n-phthaloyl gaba was administrated daily (50 mg/kg body weight-i.p) to wistar rats for 21 days and circadian rhythms of thiobarbituric acid reactive substances (tbars) and antioxidants such as reduced glutathione (gsh), catalase (cat) and superoxide dismutase (sod) were studied under constant light (ll) conditions. delayed acrophase of tbars and advanced acrophase of antioxidants (gsh, cat and ...

objective(s) the aim of this study was to evaluate the effects of dexamethasone on striatal dopaminergic, glutamatergic and gamma amino butyric acid (gaba) ergic neurotransmission in normal and parkinsonian rats. materials and methods dexamethasone (0.15, 0.30, 0.60 and 0.8 mg/kg) was administered to normal or parkinsonian rats (i.p.) followed by the analysis of the striatal neurotransmitters c...

the most important risk factors for anxiety disorders include genes, early life stress, and current stress. these factors do not act independently but interact with each other throughout human development through examples such as epigenetic modifications and complex forms of learning. the neural substrate of pathological anxiety includes hyperactivity in the amygdala and other limbic brain regi...

GABAergic drugs can change analgesic effect of morphine. Wide dynamic range (WDR) neurons play an important role in pain transmission and may change behaviors in morphine tolerance. In this study WDR neuron behaviors in morphine tolerant rats and rats treated with GABA agonists, were recorded to elucidate the effect of morphine and GABA agonists on WDR behavioral changes. Rats were divided to 4...

γ-Aminobutyric acid (GABA) is a ubiquitous nonprotein amino that has multiple physiological functions and received significant attention in the pharmaceutical food industries. Although there are many GABA-producing bacteria, high cost of strain cultivation limits its additive raw material application. In our study, Lactobacillus hilgardii GZ2, novel strain, was investigated. We attempted to rep...

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,...

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...

The high neuroactive potential of metabolites produced by gut microbes has gained traction over the last few years, with metagenomic-based studies suggesting an important role microbiota-derived γ-aminobutyric acid (GABA) in modulating mental health. Emerging evidence revealed presence glutamate decarboxylase (GAD)-encoding gene, a key enzyme to produce GABA, prominent human intestinal genus Ba...
