OBJECTIVE To observe the changes of glutamates (Glu) and gamma-aminobutyric acid (GABA) contents in brain tissue of infectious brain edema, and effects of baicalin on them in rats. METHODS The high performance liquid chromatography (HPLC) was used to determine the Glu and GABA contents in

Several hours after an hypoxic-ischemic injury to the developing brain, hyperemia, then seizures, edema, and infarction can develop. The roles of nitric oxide (NO) synthesis and excitotoxin accumulation during these later phases of injury are not known. The time course of extracellular levels of

Propofol exhibits neuroprotective effects mediated by the inhibition of excitatory amino acid (EAA) neurotransmitter release and potentiation of inhibitory amino acid (IAA) neurotransmitters. To our knowledge, this is the first study to investigate the effects of propofol on the EAA and IAA balance

Brain edema sufficient to cause intracranial hypertension and brain herniation remains a major cause of mortality in acute liver failure (ALF). Studies in experimental animal models of ALF suggest a role for ammonia in the pathogenesis of both encephalopathy and brain edema in this condition. As

The GABA amides of the antidepressants nortriptyline and fluoxetine, 1 and 2, were compared to their respective parent compounds in rodent models of pain. The amides significantly reduced early nociceptive and late inflammatory responses compared to nortriptyline or fluoxetine, where 1 exhibited

The aim of this study was to investigate the potential anti-inflammatory and anti-oxidant effects of gabapentin (GBP) in mice. The anti-inflammatory and anti-oxidant effects were evaluated using various mediators that induce paw edema, peritonitis model, myeloperoxidase (MPO) activity,

Previous studies have demonstrated that bicuculline-induced seizures of 1-2 h in duration lead to structural, metabolic, and circulatory alterations in the rat brain. Such alterations were observed even though cerebral oxygenation seemed adequate. In the present study, we explored whether

Bilobalide, a constituent of Ginkgo biloba, has neuroprotective properties. Its mechanism of action is unknown but it was recently found to interact with neuronal transmission mediated by glutamate, gamma-aminobutyric acid (GABA) and glycine. The goal of this study was to test the interaction of

Vigabatrin is a new antiepileptic drug that acts by the irreversible inhibition of gamma-aminobutyric acid (GABA) aminotransferase. During animal safety testing, vigabatrin was found to cause reversible intramyelinic edema in the brains of rodents and dogs but not in primates. In humans, the drug is

Recent studies have demonstrated that the central nervous system controls inflammatory responses by activating complex efferent neuroimmune pathways. The present study was designed to evaluate the role that central gamma-aminobutyric acid type B (GABA-B) receptor plays in neutrophil migration in a

Introduction: Encephalitis with gamma-aminobutyric acid (GABA)-B receptor antibodies (GABA-B receptor encephalitis) is known to have underlying neoplastic condition in half of the cases; however, there could be an additional event that

Hexachlorophene (HCP) is known to induce myelin vacuolation corresponding to intramyelinic edema of nerve fibers in the central and peripheral nervous system in animals. This study investigated the effect of maternal exposure to HCP on hippocampal neurogenesis in rat offspring using pregnant rats

Vigabatrin (Sabril) is a gamma-aminobutyric acid-transaminase (GABA-T) inhibitor that is effective in the treatment of certain types of drug-resistant or uncontrolled epilepsy but is known to cause microscopic vacuolation (intramyelinic edema) in the brains of treated rats, mice, and dogs. The

OBJECTIVE Children who experience complex febrile seizures are at a higher risk of subsequent epileptic episodes, and they may require therapy. This issue can be resolved by interventional studies using molecular targets identified and defined in animal models. In the current study, the molecular

BACKGROUND Mechanical ventilators are increasingly used in critical care units. However, they can cause lung injury, including pulmonary edema. Our previous studies indicated that γ-aminobutyric acid (GABA) receptors are involved in alveolar-fluid homeostasis. The present study investigated the role
