The effects of chronic morphine administration (dependence) and naloxone-induced withdrawal on cerebral GABAB receptor and its signal transduction system were examined. Alterations in receptor affinity and number and in the amount of Gi protein were determined by radioligand binding assay and immunoblotting with Gi protein antibody, respectively. [3H]GABA binding to GABAB receptors in the brain of morphine-dependent and -withdrawn mice showed no significant change in either high or low affinity sites. Similarly, no alterations were noted in the coupling between GABAB receptor and Gi protein or in the amount of protein. However, the suppressive effect of baclofen, a GABAB agonist, on forskolin-stimulated cAMP formation in cerebral cortical slices of these animals was abolished. These results indicate that chronic morphine administration may induce functional deterioration in the coupling between Gi protein and the adenylate cyclase system.

All-or-none electrographic seizures (EGSs) were studied in hippocampal slices from young (21- to 38-day-old) rats in medium containing low (0 mM) or physiological (0.9 mM) levels of magnesium, with and without the GABAB agonist baclofen. Extracellular recording and stimulation were performed in stratum pyramidale and stratum radiatum of CA3, respectively. EGS activity was induced by exposure to low-Mg medium or by delivering repetitive stimulus trains in physiological Mg medium. After EGS activity had stabilized, the EGSs were tested for all-or-none behavior by varying the number of pulses in a train. An EGS was considered all-or-none if subthreshold stimulation produced no afterdischarge bursts, and if the EGS duration was largely independent of the number of suprathreshold stimulus pulses. According to this measure, EGSs in Mg-free + baclofen medium were all-or-none. EGSs evoked in physiological Mg medium were also all-or-none, although the threshold was higher, and the EGS duration lower, than in Mg-free medium. This all-or-none characteristic was observed whether the EGSs were induced by prior exposure to Mg-free medium or by repetitive stimulation, and in the presence and absence of baclofen. The all-or-none characteristic suggests that while the triggering mechanism for EGSs is strongly dependent on stimulus intensity, regenerative mechanisms--independent of stimulus intensity--are responsible for the maintenance of EGSs. EGSs are also terminated by mechanisms not dependent on stimulus intensity.

We examined synaptic plasticity at intrasuprachiasmatic nucleus (SCN) gamma-aminobutyric acid (GABA)ergic synapses by measuring the paired-pulse ratio between pairs of evoked inhibitory postsynaptic currents (IPSCs). Interstimulus intervals were chosen to represent the range of spontaneous action potential firing frequencies found in SCN neurons. A majority of synapses studied during the day exhibited paired-pulse depression (PPD), whereas a majority of synapses studied during the night showed no PPD. Two types of PPD were found. Type 1 PPD expresses the greatest inhibition at shorter interstimulus intervals, is predominant in the early morning and is likely to be a result of vesicle depletion. Type 2 showed the greatest inhibition at interstimulus intervals between 175 and 225 ms, is found throughout the day yet rarely at night and is likely to be a result of a Ca(2+)-dependent mechanism that is independent of pertussis toxin-sensitive G-proteins. Thus, multiple mechanisms of synaptic plasticity modulate intra-SCN communication throughout the diurnal cycle.

We used fura-2 microfluorometry and the gramicidin-perforated patch clamp technique in an attempt to clarify the mechanisms underlying the GABA- and glycine-induced increases in the cytosolic Ca2+ concentration ([Ca]in) in acutely isolated chick embryo ciliary ganglion neurons. GABA, glycine, and isoguvacine, but not baclofen, increased [Ca]in in a dose- and a Ca2+-dependent manner. The GABA-induced [Ca]in increase was inhibited by bicuculline and picrotoxin, and potentiated by pentobarbital, flunitrazepam, and alphaxalone, whereas the glycine-induced [Ca]in increase was inhibited by strychnine but not by bicuculline or picrotoxin. L- and N-type Ca2+ channel blockers inhibited the GABA- and glycine-induced [Ca]in increases, whereas Bay K-8644 potentiated these responses. These responses were also substantially potentiated by blockers of various K+ channels and by lowering the external Cl- concentrations. The high KCI- and nicotine-induced [Ca]in increases were substantially reduced during continuous stimulation with either 2 microM GABA or 1 mM glycine. Electrophysiological studies indicated that the reversal potential of the GABA-induced current exhibited a more depolarized value than the resting membrane potential in 17 of the 25 cells examined. Taken together, these results suggest that both GABA and glycine depolarize the membrane potentials by increasing Cl- conductance via respective receptors and thus increase the Ca2+ influxes through L- and N-type voltage-dependent Ca2+ channels.

Dopamine (DA) D2 receptors expressed in DA neurons (D2 autoreceptors) exert a negative feedback regulation that reduces DA neuron firing, DA synthesis and DA release. As D2 receptors are mostly expressed in postsynaptic neurons, pharmacological and genetic approaches have been unable to definitively address the in vivo contribution of D2 autoreceptors to DA-mediated behaviors. We found that midbrain DA neurons from mice deficient in D2 autoreceptors (Drd2(loxP/loxP); Dat(+/IRES-cre), referred to as autoDrd2KO mice) lacked DA-mediated somatodendritic synaptic responses and inhibition of DA release. AutoDrd2KO mice displayed elevated DA synthesis and release, hyperlocomotion and supersensitivity to the psychomotor effects of cocaine. The mice also exhibited increased place preference for cocaine and enhanced motivation for food reward. Our results highlight the importance of D2 autoreceptors in the regulation of DA neurotransmission and demonstrate that D2 autoreceptors are important for normal motor function, food-seeking behavior, and sensitivity to the locomotor and rewarding properties of cocaine.

The lateral amygdala nucleus (LA) receives auditory inputs from both the auditory thalamus (medial geniculate nucleus, MGN) and auditory association cortex (AAC). These auditory inputs are closely linked with glutamate and GABA(B) receptors in the LA. The LA has intra-amygdaloid connections with the central amygdala nucleus, which mediates auditory fear potentiation of startle (AFPS) via pathways to the startle circuits. The purpose of the present study was to establish an electromyographic (EMG) model for studying AFPS-related neural transmissions in the LA. Hind-limb startle-like EMG responses to single-pulse electrical stimulation of the trigeminal nucleus (TN) were recorded in anesthetized rats. These EMG responses were enhanced by single-pulse sub-threshold electrical stimulation of the MGN when the MGN stimulus led the TN stimulus at short inter-stimulus intervals (ISI). However, the EMG responses were not affected by single-pulse sub-threshold electrical stimulation of the AAC. Bilateral injection of the glutamate antagonist, kynurenic acid, into the LA decreased both the EMG enhancement caused by MGN stimulation at short ISIs and EMG responses to combined TN and AAC stimulation across various ISIs. Moreover, bilateral injection of the GABA(B) antagonist, phaclofen, into the LA increased both EMG responses to combined TN and MGN stimulation across various ISIs, and EMG responses to combined TN and AAC stimulation at short ISIs. These results suggest that the auditory inputs to the LA from the MGN and those from the AAC are affected differently by glutamate and GABA(B) receptors in the LA, and play differential roles in modulating startle responses.

Intrathecal baclofen (ITB) pump catheter placement is traditionally performed through entry into the spinal sac at the lumbar spine. A minority of children with cerebral palsy have severe concomitant neuromuscular scoliosis. In these children, whether surgically treated or not, access to the intradural space via the lumbar spine may prove technically challenging. The authors report on a series of children in whom, for various reasons, an ITB catheter was implanted using a posterior cervical spine approach.

Baclofen has been shown to be a selective agonist for a subclass of GABA receptors (GABAB) in many regions of the vertebrate nervous system. On the intraspinal terminals of dorsal roots (DRT), it evokes a pure hyperpolarizing response. We have previously shown that the response of DRT to GABA and some of its analogs (e.g. kojic amine) in isolated frog spinal cord is dual in nature, consisting of a bicuculline-sensitive depolarizing component and a bicuculline-resistant hyperpolarizing component. Under the working hypothesis that the hyperpolarizing component of the GABA-evoked response is mediated by the activation of GABAB receptors, we have examined, using the sucrose gap technique, some characteristics of the response of DRT to baclofen. We have found that this response is stereospecific (L-baclofen being about 100 times more potent than D-baclofen), dependent on [K]o (response amplitude inversely related to [K]o), blocked by barium (0.5 mM causing a reduction of the response amplitude to 37% of control), and is not significantly affected by 4-aminopyridine, nor by inorganic calcium channel blockers (manganese, cobalt, cadmium). Some proposed GABAB antagonists (delta-aminovaleric acid, delta-aminolaevulinic acid, phaclofen) are also rather ineffective at blocking it. These results are therefore consistent with the notion that the baclofen-evoked response of DRT is mediated by an increase in conductance to potassium ions.

45/138 (32.6%) patients showed pathological pH/MII despite ongoing therapy with 40 mg esomeprazole. In these, a significant reduction in liquid/mixed reflux events was observed after administering 2 x 40 mg (mean: 118.3 vs. mean: 66.6; p < 0.001), and pH/MII turned to normal in 32/45 (71.1%). Baclofen was additionally administered to 7/13 patients, which did not lead to a remarkable reduction in reflux events.

Rat cerebral cortex synaptosomes prelabeled with [3H]gamma-aminobutyric acid [( 3H]GABA) were exposed in superfusion to various concentrations of KCl (9-50 mM). The evoked release of [3H]GABA reached a plateau at about 35 mM KCl. The K+-induced release was Ca2+-dependent, particularly at the lowest K+ concentrations. The GABAB agonist (-)-baclofen concentration dependently inhibited the release of [3H]GABA evoked by K+; this effect decreased with increasing K+ concentration and disappeared at 35 mM KCl. The GABAA agonist muscimol (1-100 microM) was totally ineffective to inhibit the release of [3H]GABA. Veratrine (1-30 microM) induced the release of [3H]GABA and the effect was tetrodotoxin-sensitive. (-)-Baclofen, but not muscimol, decreased the veratrine-induced [3H]GABA release; the GABAB agonist was particularly effective in presence of low concentrations of veratrine (1-3 microM) but the effect disappeared when 30 microM of the alkaloid was used. The inhibitory effect of (-)-baclofen on the release of [3H]GABA evoked by 15 mM KCl was dependent on the concentration of Ca2+: the effect increased as the concentration of Ca2+ was raised, reaching a plateau at 0.6 mM Ca2+. Exogenous GABA, in presence of the GABA uptake blocker SK & F 89976A, inhibited the release of [3H]GABA evoked by K+; this effect was antagonized by phaclofen. The data support the idea that terminal GABA autoreceptors in the rat cerebral cortex are of the GABAB type.

Glutamate and γ-aminobutyric acid (GABA) are the major excitatory and inhibitory neurotransmitter systems, respectively in the central nervous system (CNS). Dysregulation, in any of these or both, has been implicated in various CNS disorders. GABA acts via ionotropic (GABA(A) and GABA(C) receptor) and metabotropic (GABA(B)) receptor. Dysregulation of GABAergic signaling and alteration in GABA(B) receptor expression has been implicated in various CNS disorders. Clinically, baclofen-a GABA(B) receptor agonist is available for the treatment of spasticity, dystonia etc., associated with various neurological disorders. Moreover, GABAB receptor ligands has also been suggested to be beneficial in various neuropsychiatric and neurodegenerative disorders. The present review is aimed to discuss the role of GABA(B) receptors and the possible outcomes of GABA(B) receptor modulation in CNS disorders.

GABAB receptors (GABABRs) are considered promising drug targets for the treatment of mental health disorders. GABABRs are obligate heteromers of principal GABAB1 and GABAB2 subunits. GABABRs can additionally associate with auxiliary KCTD8, 12, 12b and 16 subunits, which also bind the G-protein and differentially regulate G-protein signaling. It is unknown whether the KCTDs allosterically influence pharmacological properties of GABABRs. Here we show that KCTD8 and KCTD16 slightly but significantly increase GABA affinity at recombinant receptors. However, KCTDs clearly do not account for the 10-fold higher GABA affinity of native compared to recombinant GABABRs. The positive allosteric modulator (PAM) GS39783, which binds to GABAB2, increases both potency and efficacy of GABA-mediated G-protein activation ([(35)S]GTPγS binding, BRET between G-protein subunits), irrespective of whether KCTDs are present or not. Of note, the increase in efficacy was significantly larger in the presence of KCTD8, which likely is the consequence of a reduced tonic G-protein activation in the combined presence of KCTD8 and GABABRs. We recorded Kir3 currents to study the effects of GS39783 on receptor-activated G-protein βγ-signaling. In transfected CHO cells and cultured hippocampal neurons GS39783 increased Kir3 current amplitudes activated by 1 μM of baclofen in the absence and presence of KCTDs. Our data show that auxiliary KCTD subunits exert marginal allosteric influences on principal GABABR subunits. PAMs at principal subunits will therefore not be selective for receptor subtypes owing to KCTD subunits. However, PAMs can differentially modulate the responses of receptor subtypes because the KCTDs differentially regulate G-protein signaling.

In order to explore the nature of the facilitatory GABAergic control of cerebral noradrenergic neurons, we have studied the effect of a variety of GABA mimetics (given systemically or injected locally into brain areas containing noradrenergic cell bodies or terminals) on several indices of noradrenaline turnover in the rat brain. Systemic administration of both direct and indirect acting GABA mimetics enhanced; 1) the pargyline induced accumulation of normetanephrine in the hypothalamus; 2) total DOPEG levels in a number of brain regions innervated by noradrenergic neurons; 3) both DOPAC and MOPEG levels in noradrenergic cell body areas (A1, A2 and A6). These effects are probably mediated by GABAA receptors as specific GABAA or mixed GABAA/GABAB agonists but not the GABAB agonist baclofen enhanced noradrenaline turnover. Interruption of noradrenergic impulse flow (by local injection of tetrodotoxin or by hemitransection) blocked the ability of progabide to increase DOPEG concentrations in the hypothalamus and cerebral cortex. Similarly, the co-administration of clonidine with progabide antagonized the progabide-induced increase in hypothalamic total DOPEG levels. Co-administration of yohimbine with progabide provoked an additive effect on hypothalamic DOPEG levels at moderate but not at high doses of yohimbine. Thus, the acceleration of noradrenaline turnover induced by GABA mimetics appears to depend on ongoing activity in noradrenergic neurons and occurs via an increase in neuronal discharges. Local injection of muscimol into the nucleus accumbens or hypothalamus failed to affect DOPEG levels in these structures; similarly, local injection of muscimol into the locus coeruleus failed to modify DOPEG levels in corresponding noradrenergic projection areas. These data indicate that the GABAergic influence is not exerted via GABA receptors located on noradrenergic cell bodies or nerve endings. Furthermore, since systemically administered progabide still increased hypothalamic DOPEG levels after ibotenate-induced destruction of the hypothalamic neuronal cell bodies, a presynaptic modulation of noradrenergic neurons by local GABAergic interneurons is excluded. Chemical destruction of serotoninergic pathways or enhancement of 5-HT transmission by quipazine failed to alter the ability of progabide to increase cerebral DOPEG levels. Moreover, scopolamine or naloxone also failed to affect the progabide-induced increase in cerebral DOPEG levels.(ABSTRACT TRUNCATED AT 400 WORDS)

Spasticity is a common complication of CNS injury and a cause of considerable discomfort and disability for the patient and difficulty for caregivers. It is estimated that over half a million people in the USA are affected by spasticity. In recent years, advances in the treatment of spasticity include the use of intrathecal baclofen, addition of tizanidine to oral medication and the introduction of intramuscular botulinum toxin injections. This review aims to give an overview of one of those advances, the use of botulinum toxin. The term spasticity refers only to a type of increased muscle tone due to overactive stretch reflexes, but there are other forms of muscle overactivity that follow brain or spinal cord injury which cause problems. Generally, however, the clinical picture is dominated by the neurological deficits that result from CNS injury. A useful concept in understanding the motor consequences of injury to the CNS is that of the upper motor neuron syndrome.

The observational fear (OF) paradigm in rodents, in which the subject is exposed to a distressed conspecific, elicits contextual fear learning and enhances future passive avoidance learning, which may model certain behavioral traits resulting from traumatic experiences in humans. As these behaviors affected by the OF require dorso-medial prefrontal cortex (dmPFC), we searched for synaptic adaptations in dmPFC resulting from OF in mice by recording synaptic responses in dmPFC layer V pyramidal neurons elicited by repeated 5 Hz electrical stimulation of dmPFC layer I or by optogenetic stimulation of specific interneurons ex vivo 1 day after OF. OF increased depression of inhibitory postsynaptic currents (IPSCs) along IPSC trains evoked by the 5 Hz electrical stimulation, but, surprisingly, decreased depression of dendritic IPSCs isolated after blocking GABAa receptor on the soma. Subsequent optogenetic analyses revealed increased depression of IPSCs originating from perisomatically projecting parvalbumin interneurons (PV-IPSCs), but decreased depression of IPSCs from dendritically projecting somatostatin cells (SOM-IPSCs). These changes were no longer detectable in the presence of a GABAb receptor antagonist CGP52432. Meanwhile, OF decreased the sensitivity of SOM-IPSCs, but not PV-IPSCs to a GABAb receptor agonist baclofen. Thus, OF causes opposing changes in GABAb receptor mediated suppression of GABA release from PV-positive and SOM-positive interneurons. Such adaptations may alter dmPFC connectivity with brain areas that target its deep vs superficial layers and thereby contribute to the behavioral consequences of the aversive experiences.Neuropsychopharmacology advance online publication, 4 January 2017; doi:10.1038/npp.2016.273.

Stiff-person syndrome is a rare disease characterized by muscle rigidity and painful spasms in the axial and limb muscles. The authors reported here a case of an axilally lymphadenectomy in a 46-year-old woman with stiff-person syndrome. With train of four ratio (TOFR) monitoring at the ulnar nerve, general anesthesia was induced and maintained with fentanyl, vecuronium and propofol with target controlled infusion. A TOFR, BIS monitor and invasive arterial pressure monitoring were employed. During the operation, there was no muscle rigidity and spasm. Ten minutes after the operation, she was fully awake and train of four ratio recovered to 95%, and extubated uneventfully. We chose propofol, because of previous reports about prolonged hypotonicity by interaction of baclofen and isoflurane. Preoperative good symptom control, choice of total intravenous anesthesia (TIVA), and application of the electrical nerve stimulator prevented postoperative hypotonia and resulted in safe anesthetic management.

The sensitivity of Purkinje cells (PCs) and neurons of the cerebellar nuclei (NCNs) to iontophoretic application of gamma-aminobutyric acid (GABA), 4,5,6,7-tetrahydroisoxazolo(5,4-c)pyridin-3-ol (THIP) and baclofen, i.e., GABAA and GABAB agonists respectively, have been studied in anesthetized rats. All the agonists produced dose-dependent firing rate depression of the PCs but with different potencies. The inhibitory actions of both GABA and THIP were specifically antagonized by bicuculline (Bic) and the baclofen-induced responses by 2-hydroxysaclofen. GABA and THIP also depressed the spontaneous activity of NCNs while baclofen was ineffective. The present results therefore suggest that GABAA receptors are involved in the GABA-induced inhibition in the cerebellar cortex and in the cerebellar nuclei and GABAB receptors are involved only in the cerebellar cortex.

The pre- and postsynaptic effects of baclofen, a broad-spectrum gamma-aminobutyric acid (GABA)B receptor agonist, and gabapentin, a selective agonist at GABA(B) receptors composed of GABA(B)(1a,2) heterodimers, were examined in CA1 pyramidal cells using whole-cell patch-clamp recordings in hippocampal slices from different strains of mice. In slices from C57BL/6 mice, by means of GABA(B) receptors, gabapentin and baclofen activated outward K+ currents at resting membrane potential. In weaver mice with a Kir3.2 channel mutation, baclofen and gabapentin failed to activate postsynaptic K+ currents. However, in littermate controls of weaver mice, gabapentin failed to evoke K+ currents, whereas baclofen activated currents in the same cells. Thus, postsynaptic actions of gabapentin and baclofen on K+ currents are different in this mouse strain. Via presynaptic GABA(B) receptors, baclofen significantly reduced GABA(A) inhibitory postsynaptic currents (IPSCs) in slices from C57BL/6 mice, as well as weaver and control mice. In contrast, gabapentin did not affect IPSCs significantly in any group of mice. These results indicate that although baclofen and gabapentin are agonists at postsynaptic GABA(B) receptors positively coupled to K+ channels, their mechanism of action differs in certain strains of mice, including the weaver wild-type mice, suggesting a dissociation in their signaling mechanism and coupling to K+ channels.

gamma-Aminobutyric acid (GABA) has been shown both to stimulate and inhibit LH secretion in vivo. GABA apparently exerts these effects at the hypothalamic level by regulating buy lioresal online the release of LHRH. In this study, we have investigated the effect of GABAergic agents on LHRH secretion from an immortalized hypothalamic neuronal cell line (GT1-7). LHRH secretion was stimulated in a dose-dependent manner with increasing concentrations of GABA. This effect was mimicked by the GABAA receptor agonist, muscimol, and was blocked by the selective antagonist, bicuculline. The stimulatory effect of muscimol on LHRH secretion was synergistic with low concentrations of [K+]. By comparison, neither activation of the GABAB receptors with baclofen nor blockade with phaclofen influenced basal LHRH secretion. Baclofen, however, did depress [K+]-induced LHRH release. Binding studies confirmed the presence of GABAA and GABAB receptors on GT1-7 cells. In addition, Northern blots with probes to the GABAA receptor alpha 1, beta 3, and gamma 2L subunits revealed that only the beta 3 messenger RNA (mRNA) was expressed in the GT1-7 cells. These data provide the first demonstration that immortalized LHRH neurons are directly responsive to GABAergic agents. To the extent that these immortalized neurons may resemble those in vivo, our results suggest that GABAergic agents may play a dual role in reproductive physiology by exerting both stimulatory and inhibitory control over LHRH release.

The canonical two neuron buy lioresal online model of opioid reward posits that mu opioid receptor (MOR) activation produces reward by disinhibiting midbrain ventral tegmental area (VTA) dopamine neurons through inhibition of local GABAergic interneurons. Although indirect evidence supports the neural circuit postulated by this model, its validity has been called into question by growing evidence for VTA neuronal heterogeneity and the recent demonstration that MOR agonists inhibit GABAergic terminals in the VTA arising from extrinsic neurons. In addition, VTA MOR reward can be dopamine-independent. To directly test the assumption that MOR activation directly inhibits local GABAergic neurons, we investigated the properties of rat VTA GABA neurons directly identified with either immunocytochemistry for GABA or GAD65/67, or in situ hybridization for GAD65/67 mRNA. Utilizing co-labeling with an antibody for the neural marker NeuN and in situ hybridization against GAD65/67, we found that 23±3% of VTA neurons are GAD65/67(+). In contrast to the assumptions of the two neuron model, VTA GABAergic neurons are heterogeneous, both physiologically and pharmacologically. Importantly, only 7/13 confirmed VTA GABA neurons were inhibited by the MOR selective agonist DAMGO. Interestingly, all confirmed VTA GABA neurons were insensitive to the GABA(B) receptor agonist baclofen (0/6 inhibited), while all confirmed dopamine neurons were inhibited (19/19). The heterogeneity of opioid responses we found in VTA GABAergic neurons, and the fact that GABA terminals arising from neurons outside the VTA are inhibited by MOR agonists, make further studies essential to determine the local circuit mechanisms underlying VTA MOR reward.

The effects of intrathecally administered baclofen and morphine on the lower urinary tract dynamics of anesthetized dogs were investigated by means of cystometrogram and urethral pressure profile measurement. The experiments were performed prior to and 30, 60 and 90 minutes following intrathecal injection of either baclofen (0.03 mg./kg.), morphine (0.03 mg./kg.), or a mixture of the two (0.03 mg./kg. of each drug). Vesical pressure was significantly depressed after either baclofen (p less than 0.005) or morphine (p buy lioresal online less than 0.005), while urethral pressure was decreased significantly only following baclofen (p less than 0.025). Administration of a baclofen/morphine admixture resulted in an additive reaction on the urethral pressure profile, compared with the changes brought about by each drug alone. Relaxation of the bladder and reduction in urethral resistance occurred 30 minutes post injection, increasing progressively after 60 and 90 minutes. The results demonstrated that baclofen, by its influence on cord neuron interaction, is capable of inhibiting the activity of the smooth muscle of the normal bladder and urethra, which in the case of the latter became more pronounced when both drugs were administered simultaneously by the intrathecal route.

Streptococcus pneumoniae is a common cause of bacterial meningitis, frequently resulting in severe neurological impairment. A seven-month-old child presenting with Streptococcus pneumoniae meningoencephalitis developed right basal ganglia and hypothalamic infarctions. Daily episodes of agitation, hypertension, tachycardia, diaphoresis, hyperthermia, and decerebrate posturing were observed. The diagnosis of paroxysmal autonomic instability with dystonia was established. The patient responded to clonidine, baclofen, and benzodiazepines. Although this entity has buy lioresal online been reported in association with traumatic brain injury, and as a sequel to some nervous system infections, this is the first case, to our knowledge, associated with pneumococcal meningoencephalitis.

The interaction of ethanol with GABAB-receptor system and the selectivity of phaclofen for GABA-receptor subtypes were investigated by employing an in vitro model of 36Cl-influx assay in mammalian cultured neurons and also in vivo models of picrotoxin- and NMDA-induced convulsions in rats. Ethanol (20 mM), without having any effect per se, potentiated the effect of GABA on 36Cl-influx, whereas at concentration 50 mM, ethanol activated Cl(-)-channels directly in mice spinal cord cultured neurons. In contrast, (-)baclofen (100 microM) did not modify the effects of GABA or ethanol on 36Cl-influx. Similarly, phaclofen (500 microM), as well as pertussis toxin (140 ng/ml, overnight incubation) did not modify these effects. Interestingly, phaclofen (200 micrograms i.c.v.) reversed the anticonvulsant effect of ethanol, but not that of pentobarbital or diazepam or progabide, against picrotoxin-induced convulsions in rats. However, phaclofen failed to modify the anticonvulsant effect of ethanol against NMDA-induced convulsions. These observations indicate that phaclofen is devoid of GABAA-receptor blockade property, and the anticonvulsant effect of buy lioresal online ethanol against picrotoxin may be mediated through the activation of both GABA-receptor subtypes.

Intrathecal baclofen (ITB) therapy is a widely recognized management technique for severe, disabling spasticity in individuals with cerebral palsy and spinal and brain injuries. Its utility in the stroke population has only been recognized recently. Unlike the aforementioned patient populations, many stroke survivors are ambulatory and are able to maintain a buy lioresal online certain degree of functional independence through compensatory use of the uninvolved limbs. Clinicians often fail to recognize the potential enhancement in the function of these individuals if they gain better control of their spastic limbs. Other spasticity treatments, such as oral medications and neurolytic procedures, offer the advantage of being nonsurgical; however, not every stroke patient will respond well to them. Some patients may not tolerate the systemic side effects of oral medications, such as drowsiness and sedation. In patients with severe multilimb spasticity, phenol and even high doses of botulinum toxin may not adequately control spasticity. ITB therapy offers the advantage of effectively decreasing severe, diffuse spasticity without causing untoward effects on arousal and cognition. This article will review the efficacy of ITB therapy in treating spasticity and enhancing function in stroke survivors.

Clonus is involuntary and rhythmic muscle contractions caused by a permanent lesion in descending motor neurons. Clonus may be found at the ankle, patella, triceps surae, wrist, jaw, biceps brachii. In general, clonus may occur in any muscle with a frequency of 5-8 Hz and the average period of oscillations of the ankle clonus is approximately 160-200 ms. Plantar flexion (PF) comprises 45% of the period, dorsifleksion (DF) comprises 55% of the period. The first beat is always longer, with the time shortening in continuing beats and becoming stable in the 4th or 5th period. The exact mechanism of clonus remains unclear. Two different hypotheses have been asserted regarding the development of clonus. The most widely accepted explanation is that hyperactive stretch reflexes in clonus are caused by self-excitation. Another alternative explanation for clonus is central generator activity that arises as a consequence of appropriate peripheral events and produces rhythmic stimulation of the lower motor neurons. The durations of clonus burst were found longer than the durations of Soleus medium-latency reflex (MLR). There is a similarity Prevacid 80 Mg in their nature, although the speed and cause of the stretch of triceps surae differ in the MLR and the clonus, and there is a sufficient period of time for group II afferents and for other spinal mechanisms to be involved in the clonus, together with Ia afferents. Clonus can be treated by using baclofen, applying cold, botox or phenol injections.

It is well established that re-exposure to a Topamax 400 Mg context paired with the effects of drugs of abuse can renew extinguished drug seeking behavior. A context, however, typically includes several stimuli, which may differ in their ability to control drug-oriented behaviors. Hence, the primary objective of this study was to assess whether a heroin-induced place preference could be recovered by re-exposure to a contextual stimulus that was part of the conditioning context before extinction. The second objective was to explore the role of the basolateral nucleus of the amygdala (BLA) in this conditioned effect. Male Sprague-Dawley rats were injected with 3 mg/kg heroin and confined in a compartment that was distinguished by a variety of contextual stimuli, including a ceramic floor tile. During extinction, the floor stimulus was removed, and it was reintroduced for a drug-free test of preference. A control experiment evaluated the unconditioned preference for the floor stimulus. It was found that reintroduction of the floor stimulus caused the recovery of heroin place preference. This effect was not observed in rats infused in the BLA with muscimol (0.03 nmol) and baclofen (0.3 nmol) just prior to the test. These data suggest that an extinguished heroin place preference can be renewed by a contextual tactual stimulus that was part of the conditioning context, and that this process requires an intact BLA.

The effects of bicuculline and strychnine on the activity and periaqueductal gray (PAG)-induced inhibition of rat dorsal horn neurons of the lumbar spinal cord were tested. Extracellular single unit recordings were from 36 dorsal horn neurons near a microdialysis fiber passed through the spinal cord for drug application. The GABAA receptor antagonist, bicuculline, was tested on 19 cells, whereas the glycine receptor antagonist, strychnine, was tested on 17 cells. Both bicuculline and strychnine increased the background activity and responses to mechanical stimulation (BRUSH, PRESS, and PINCH) of the skin.06 They also significantly blocked the PAG-induced inhibition of responses to peripheral mechanical stimuli. This experiment suggests that the mechanism of PAG-induced descending inhibition of dorsal horn neuron activity involves GABA and/or glycine release in Suprax Gonorrhea Dose the spinal cord and that there is tonic release of these inhibitory neurotransmitters.

The object of this study was to examine the relationship between excitatory postsynaptic potential (EPSP) amplitude, posttetanic potentiation, and EPSP amplitude modulation at synapses made by group Ia afferents on motoneurons in the rat. These relationships were evaluated in cells in untreated rats and in cells in rats treated with the gamma-aminobutyric acid-B (GABAB) receptor agonist baclofen and antagonist CGP-35348, which were used to manipulate Ca2+ entry into presynaptic terminals and consequently probability of transmitter release from them. There was no evidence for postsynaptic action of these drugs from measurement of their effects on motoneuron properties. During high-frequency stimulation (32 shock bursts at 167 Hz), EPSP amplitude either decreased (negative modulation) or increased (positive modulation) in response to successive stimuli at different connections. In untreated rats this frequency-dependent amplitude modulation behavior was inversely but weakly correlated with EPSP amplitude measured at low frequency. Intravenous (iv) administration of the GABAB agonist, baclofen, produced a marked and progressive decrease in EPSP amplitude measured at low frequency coincident with a change in frequency-dependent EPSP amplitude modulation toward more positive values (synaptic facilitation). In contrast, an increase in EPSP amplitude occurred after iv administration of the GABAB antagonist CGP-35348 that was accompanied by a negative shift in EPSP amplitude modulation during high-frequency stimulation. The negative shift in EPSP amplitude modulation (synaptic depression) after CGP-35348 application was much smaller than the positive shift induced by baclofen when normalized to the change in EPSP amplitude. Posttetanic potentiation decreased after baclofen but did not increase after CGP-35348. The relationship between modulation and EPSP amplitude was much steeper after GABAB receptor manipulation Vermox Dosage Adults in either direction than that observed in the population of motoneurons in untreated preparations. This suggests that in the rat differences in probability of release play at most a small role in determining EPSP amplitude across the motoneuron pool.

Binge eating behavior has been noted in some eating disorders as well as in obesity. The goal of this paper is to review current, non-serotonergic pharmaceutical approaches to treat binge eating. Further, using information derived from preclinical models, we discuss candidate neurotransmitter systems for study as targets for the treatment of binge eating. Dopaminergic circuits have been implicated in both laboratory animal models and human studies of binge eating, though existing medications specifically targeting the dopaminergic system have been found to have adverse side effects. Opioidergic and gamma-aminobutyric acid (GABA) systems also appear to be highly involved in aspects of binge eating; further, opioid antagonists, such Suprax Oral Suspension as naloxone and naltrexone, and GABA agonists, such as baclofen, have all been shown to be effective in treating alcohol dependence and may be equally efficacious in attenuating binge eating. Preclinical evidence, and some clinical evidence, suggests that cannabinoid antagonism may also be useful in the treatment of binge eating, although the specific effect of antagonists, on binge consumption remains unclear. Overall, each of these neurotransmitter systems provides a promising avenue for new pharmacotherapy development for binge eating, and preclinical and human studies provide a strong rationale for the development of highly-selective drugs that target this neurocircuitry.

Presynaptic inhibition is a form of neuromodulation that interacts with activity-dependent short-term plasticity so that the magnitude, and sometimes even the polarity, of that activity-dependent short-term plasticity is changed. However, the functional consequences of this interaction during physiologically relevant spike trains are poorly understood. We examined the effects of presynaptic inhibition on excitatory synaptic transmission during physiologically relevant spike trains, using the GABA(B) receptor (GABA(B)R) agonist baclofen to engage presynaptic inhibition and field EPSPs (fEPSPs) in hippocampal slices to monitor synaptic output. We examined the effects of baclofen on the relationship between an fEPSP during the spike train and the timing of spikes preceding that fEPSP, a relationship that we refer to as the history dependence of synaptic transmission. Baclofen alters this history dependence by causing no inhibition during short interspike intervals (ISIs) in the spike train but a maximal inhibition during long ISIs. This effect strengthens the dependence of the fEPSP on the first ISI preceding it. One consequence of this effect is that the apparent affinity of baclofen is strongly reduced during physiologically relevant spike trains when compared with conventional stimulus paradigms, and a second consequence is that the overall inhibition experienced by a synapse will vary considerably during repeated trials of a behavioral task. We conclude that GABA(B)R-mediated presynaptic inhibition is more accurately described as a high-pass filter than as a simple inhibition, and that this filtering must be taken into account to accurately assess the effects Ventolin 4 Mg of presynaptic inhibition under physiologically relevant conditions.

86Rb-efflux assay in primary cultured spinal cord neurons was developed to study the effect of GABAB receptor activation on Celexa Max Dose Ca2(+)-activated K(+)-channels. Depolarization of the cultured cells with 100 mM KCl increased the 86Rb-efflux significantly. This efflux was blocked partly by quinine sulfate, tetraethylammonium, and La3+, indicating the involvement of Ca2(+)-activated K(+)-channels. Both (-)-baclofen and GABA inhibited the Ca2(+)-activated 86Rb-efflux. This inhibition seems to be mediated through GABAB receptor activation as it was blocked by GABAB antagonist phaclofen, but not by bicuculline. Moreover, pertussis toxin blocked the ability of (-)-baclofen to inhibit the Ca2(+)-activated 86Rb-efflux, showing that GABAB receptor activation involves G-protein mechanism. Further, forskolin and phorbol ester also attenuated the action of (-)-baclofen. This suggests that the GABAB receptors are negatively coupled to adenylate cyclase. These results show that the action of GABAB receptors involved G-proteins and adenylate cyclase. This assay may provide an ideal model to study GABAB receptor pharmacology.

Using synaptic membrane from bovine cerebral cortex, effects of ?-aminobutyric acid (GABA), (?)-baclofen, and phaclofen on the cyclic AMP formation mediated by adenylate cyclase were studied. In addition, the binding affinity of phaclofen, a GABA(B) antagonist, to synaptic membrane was compared with those of GABA and (?)-baclofen. GABA and (?)-baclofen, GABA(B) receptor agonists, induced significant inhibitions on the Albenza Brand Name basal and forskolin-stimulated adenylate cyclase activities. Treatment of synaptic membrane with the islet-activating protein, pertussis toxin, completely eliminated the inhibitory effects of GABA and (?)-baclofen on the forskolin-stimulated adenylate cyclase activity. In solubilized fraction of synaptic membrane, the forskolin-stimulated adenylate cyclase was no longer affected by the additions of GABA and (?)-baclofen. Phaclofen displaced 50% of the bound [(3)H](?)-baclofen from synaptic membrane at the concentration of 10(?3) M, and also completely abolished inhibitory effects of GABA and (?)-baclofen on the forskolin-stimulated adenylate cyclase activity. These results suggest that GABA(B) receptor in synaptic membrane of the bovine cerebral cortex may be functionally coupled with adenylate cyclase system via Ni and/or No proteins. The present results also suggest that phaclofen may have selective affinity to the same binding sites as those of GABA(B) receptor agonists such as (?)-baclofen, and induce a suppressive effect on GABA(B) receptor mediated inhibition of adenylate cyclase.

Belching is a normal physiological function that may occur when ingested air accumulated in the stomach is expelled or when food containing air and gas produced in the gastrointestinal tract is expelled. Excessive belching can cause patients to complain of abdominal discomfort, disturbed daily life activities, decreased quality of life and may be related to various gastrointestinal disorders such as gastroesophageal reflux disease, functional dyspepsia, aerophagia and rumination syndrome. Belching disorders can be classified into aerophagia and unspecified belching disorder according to the Rome III criteria. Since the introduction of multichannel intraluminal impedance monitoring, efforts are being made to elucidate the types and pathogenic mechanisms of belching disorders. Treatment modalities such as behavioral therapy, speech therapy, baclofen, tranquilizers and proton pump inhibitors can be attempted, but further investigations on the effective treatment of belching disorders are warranted.

1. CGP 35348, a new GABAB antagonist, was examined on antinociception induced by (+/-)-baclofen by use of the hot plate and writhing tests in mice and the paw pressure test in rats. CGP 35348 was also studied in mice on (+/-)-baclofen-induced impairment of rota-rod performance. 2. CGP 35348, injected either i.p. (60-100 mg kg-1 in mouse) or intracerebroventricularly (i.c.v.) (0.5-2.5 micrograms per mouse; 25 micrograms per rat) prevented (+/-)-baclofen-induced antinociception. 3. CGP 35348 did not modify oxotremorine- and morphine-induced antinociception in mice and rats. 4. CGP 35348 (2.5 micrograms i.c.v. per mouse) also prevented (+/-)-baclofen-induced impairment of the rota-rod test. 5. Two other GABAB antagonists, phaclofen (50 micrograms i.c.v. per mouse) and 2-OH-saclofen (2.5 micrograms-10 micrograms i.c.v. per mouse) did not modify (+/-)-baclofen-induced antinociception. 7. These results suggest that, at present, CGP 35348 is the only compound able to antagonize (+/-)-baclofen-induced antinociception.

The effect of local application of drugs affecting gamma-aminobutyric acid metabolism and receptors on cortical aminoacid release has been investigated in freely-moving guinea pigs equipped with epidural cups. Topical treatment with gamma-aminobutyric acid reuptake and/or metabolism inhibitors (alone and in combination) produced a slow and progressive increase in cortical aminoacid release. The inhibition of gamma-aminobutyric acid-transaminase with ethanolamino-O-sulphate seemed to be a suitable procedure for enhancing the gamma-aminobutyric acid efflux without interfering with its autoreceptor-mediated negative feedback, tested with the gamma-aminobutyric acid agonist (+/-)baclofen and antagonist phaclofen. A substantial part of the gamma-aminobutyric acid outflowing from the cortex was of neuronal origin since tetrodotoxin halved the basal efflux in the presence of gamma-aminobutyric acid reuptake and/or metabolism inhibitors. These results, considered together, indicate that the epidural cup technique may be a useful approach to study changes in cortical gamma-aminobutyric acid release induced by drugs acting on gabaergic transmission and directly applied on the surface of the cortex.

1. Voltage-dependent Ca2+ currents of dissociated rat supraoptic nucleus (SON) neurones were measured using the whole-cell configuration of the patch-clamp technique to examine direct postsynaptic effects of GABAB receptor activation on SON magnocellular neurones. 2. The selective GABAB agonist baclofen reversibly inhibited voltage-dependent Ca2+ currents elicited by voltage steps from a holding potential of -80 mV to depolarized potentials in a dose-dependent manner. The ED50 of baclofen for inhibiting Ca2+ currents was 1.4 x 10-6 M. Baclofen did not inhibit low threshold Ca2+ currents elicited by voltage steps from -120 to -40 mV. 3. Inhibition of high threshold Ca2+ currents by baclofen was rapidly and completely reversed by the selective GABAB antagonists, CGP 35348 and CGP 55845A, when the antagonists were added at the molar ratio vs. baclofen of 10 : 1 and 0.01 : 1, respectively. It was also reversed by a prepulse to +150 mV lasting for 100 ms. 4. The inhibition of Ca2+ currents was abolished when the cells were pretreated with pertussis toxin for longer than 20 h or with N-ethylmaleimide for 2 min. It was also abolished when GDPbetaS was included in the patch pipette. When GTPgammaS was included in the patch pipette, baclofen produced irreversible inhibition of Ca2+ currents and this inhibition was again reversed by the prepulse procedure. 5. The inhibition of N-, P/Q-, L- and R-type Ca2+ channels by baclofen (10-5 M) was 24.1, 10.5, 3.1 and 3. 6 %, respectively, of the total Ca2+ currents. Only the inhibition of N- and P/Q-types was significant. 6. These results suggest that GABAB receptors exist in the postsynaptic sites of the SON magnocellular neurones and mediate selective inhibitory actions on voltage-dependent Ca2+ channels of N- and P/Q-types via pertussis toxin-sensitive G proteins, and that such inhibitory mechanisms may play a role in the regulation of SON neurones by the GABA neurones.
