The involvement of inhibitory transmitters for Ptychodiscus brevis toxin (PbTx)-induced depression of spinal synaptic transmission in neonatal rats was investigated. Stimulation of a dorsal root evoked monosynaptic reflex (MSR) and polysynaptic reflex (PSR) potentials in the segmental ventral root. The PbTx depressed the reflexes in a concentration-dependent manner and this depression was block...
GABRB3 gene is a recently identified located in 15q12 chromosome and encodes for gamma-aminobutyric acid (GABA) receptor subunit beta-3 protein, which linked to the GABAA receptor. The believed share role inhibitory GABAergic synapses, GABA iron-gated channel function, possible cellular response histamine. β3 expressed cerebral grey matter, thalami, hippocampi, cerebellum, among other structure...
1) chronic administration of morphine hydrochloride in the drinking water of mice induced physical dependence. jumping and diarrhea, two signs of withdrawal, were produced by intraperitoneal (ip) injection of naloxone. 2) baclofen, bicuculline and picrotoxin decreased the number of mice's jumping episodes and frequency of diarrhea. 3) muscimol decreased jumping but not diarrhea. 4) the data ind...
Objective(s): Many studies have focused on ventral tegmental area than of other mesocorticolimbic areas, and implicated a key role for the medial prefrontal cortex (mPFC) in the development of addictive behaviors. So far, the role of gamma-aminobutyric acid (GABA) receptors in the discriminative properties of morphine has received little attention and few studies evaluated the role of these rec...
background: the ventral tegmental area (vta) is well known for its role in cardiovascular control. it is demonstrated that about 20-30% of the vta neurons are gabaergic though their role in cardiovascular control is not yet understood. this study is carried out to find the effects of gaba a and gaba b receptors on cardiovascular response of the vta. methods: experiments were performed on uretha...
introduction: fennel is rich in phytoestrogens and is used for estrogen deficiency disorders. estrogens affect anxiety through neurochemical systems such as gaba-a receptors. in this study the effects of fennel on gaba-a and estrogen receptors in anxiety were investigated. methods: adult female wistar rats weighing (180±20 g) were divided into 8 groups. groups received saline, fennel (200, 500,...

g -Aminobutiric acid (GABA), the major inhibitory neurotransmitter in the central nervous system has two major receptor subtypes (GABAA and GABAB). GABAB receptors are activated by the antispastic and muscle relaxant agent, Baclofen, which is a lipophilic derivative of GABA. Since 1962 several strategies have been reported for the synthesis of baclofen.In this study an approach has been made to...
Introduction Licorice could exhibit beneficial effect in the management of insomnia by regulating key modulators such as GABA and serotonin, we therefore aimed to study potentail hypnotic licorice extract, glycyrrhizin (GCZ), on underlying mechanisms. Material methods Mice were randomly grouped a Control group, GCZ (low) (high) group DZP with 8 mice each group. Sleep latency, sleep duration loc...
Introduction: Fennel is rich in phytoestrogens and is used for estrogen deficiency disorders. Estrogens affect anxiety through neurochemical systems such as GABA-A receptors. In this study the effects of fennel on GABA-A and estrogen receptors in anxiety were investigated. Methods: Adult female Wistar rats weighing (180±20 g) were divided into 8 groups. Groups received saline, fennel (200, ...
