The present experiments were conducted to evaluate the possible contribution of GABAergic inputs to the basal forebrain in the region of the nucleus basalis magnocellularis (nbm) to memory. In two experiments, rats implanted with bilateral intra-nbm guide cannulae were trained in the double Y-maze task to perform working- and reference-memory components. Animals were placed in one of two start ...
In vivo effects of GABA(B) receptor-positive modulators suggest that they have therapeutic potential for treating central nervous system disorders such as anxiety, depression, and drug abuse. Although these effects generally are thought to be mediated by positive modulation of GABA(B) receptors, such modulation has been examined primarily in vitro. The present study was aimed at further examini...
BACKGROUND Intervention to achieve alcohol abstinence represents the most effective treatment for alcohol-dependent patients with liver cirrhosis; however, anticraving drugs might worsen liver disease. We aimed to investigate the effectiveness and safety of baclofen in achieving and maintaining alcohol abstinence in patients with liver cirrhosis. METHODS Between October, 2003, and November, 2...
Pre- and postsynaptic adenosine 5'-triphosphate-sensitive potassium (ATP-K+) currents were studied using whole-cell recordings from substantia nigra zona compacta "principal" neurons in midbrain slices. The GABAA and GABAB receptor-mediated synaptic potentials were unaffected by the ATP-K+ channel inhibitor glibenclamide (30 microM) or by the opener diazoxide (500 microM), indicating that ATP-K...
The pharmacological profile of the gamma-aminobutyric acid (GABA)(B) receptor regulating cholinergic twitch contraction in the guinea pig ileum myenteric plexus-longitudinal muscle preparation was investigated. GABA and (-)-baclofen inhibited the contraction, exhibiting quite close potencies (pD(2) for GABA = 5.70; pD(2) for (-)-baclofen = 5.33). The compound CGP 47656 also reduced the choliner...
Activation of gastric vagal mechanoreceptors by distention is thought to be the trigger for transient lower esophageal sphincter relaxations (TLESR), which lead to gastroesophageal reflux. The contribution of higher-threshold gastric splanchnic mechanoreceptors is uninvestigated. GABA(B) receptor agonists, including baclofen, potently reduce triggering of TLESR by low-level gastric distention. ...
BACKGROUND Several of the behavioral effects of amphetamine (AMPH) are mediated by an increase in dopamine neurotransmission in the nucleus accumbens. However, evidence shows that γ-aminobutyric acid B (GABAB) receptors are involved in the behavioral effects of psychostimulants, including AMPH. Here, we examined the effects of co-administration of the GABAB receptor agonist baclofen and a posit...
OBJECTIVE To assess changes in body composition, body weight and resting metabolic rate in patients who received intrathecal baclofen therapy for spasticity. DESIGN Prospective, longitudinal, quasi-experimental, with a pre/post design. PATIENTS Twelve patients with spasticity, fulfilling study criteria, and due for pump implantation for intrathecal baclofen therapy, completed the study. M...
CONTEXT Gamma-aminobutyric acid (GABA) is a potent inhibitory neurotransmitter. There is evidence that GABA(B) receptors located in the dorsal complex and in afferent fibers of the vagus nerve participate in the control of gastrointestinal motility. OBJECTIVE To assess the intracerebroventricularly (ICV) and intravenously (IV) effect of baclofen, a GABA(B) receptor agonist, on liquid and soli...
Spasticity is relatively common among children with cerebral palsy. This condition can be painful, can severely impair a child's ability to perform basic tasks, and can place an enormous emotional and financial burden on the family. Intrathecal baclofen delivered via an implantable pump is an effective treatment option for children unresponsive to oral medication and needing generalized motor c...
