Neurotoxic effects induced by gammahydroxybutyric acid (GHB) in male rats.

The results show for the first time that the repeated administration of GHB, especially at very low doses, produces neurotoxic effects, which is very relevant because its abuse, especially by young persons, could produce considerable neurological alterations after prolonged abuse.

γ‐Hydroxybutyrate (GHB), γ‐Butyrolactone (GBL), and 1,4‐Butanediol (1,4‐BD) Reduce the Volume of Cerebral Infarction in Rodent Transient Middle Cerebral Artery Occlusion

It is concluded that GHB, GBL, and 1,4‐BD protect against rat focal cerebral ischemia from transient MCAO.

Possible long-term effects of γ-hydroxybutyric acid (GHB) due to neurotoxicity and overdose

A single acute pharmacological dose of γ-hydroxybutyrate modifies multiple gene expression patterns in rat hippocampus and frontal cortex.

It is demonstrated that a single acute anesthetic dose of 1 g/kg GHB alters a large number of genes, 121 in hippocampus and 53 in prefrontal cortex; 16 genes were modified simultaneously in both brain regions by using DNA microarray studies.

γ‐Hydroxybutyrate: Cerebral Metabolic, Vascular, and Protective Effects

The cerebral protection afforded by each of several preparations of γ‐hydroxybutyrate (GHB) was examined in the hypoxic mouse model and brain biopsies taken after the cumulative dose of GHB 1100 mg/kg showed a trend toward lower phosphocreatine levels and higher lactate and lactate/pyruvate levels than in untreated dogs.

Significance of γ-hydroxybutyric acid in the brain

Involvement of local ischemia in endothelin-1 induced lesions of the neostriatum of the anaesthetized rat

The results indicate that ET-1 injected in the neostriatum may produce lesions by causing local ischemia, related to its vasoconstrictor activity and possibly also to an activation ofET-1 receptors in the astroglial-endothelial complex.

Neuroprotective effect of dapsone against quinolinate- and kainate-induced striatal neurotoxicities in rats.

Findings provide evidences to suggest that dapsone is acting as a neuroprotective agent against excitotoxicity induced by glutamate receptor agonists.

EFFECTS OF γ‐BUTYROLACTONE ON LOCAL CEREBRAL GLUCOSE UTILIZATION IN THE RAT

It is suggested that γ‐butyrolactone profoundly depresses cerebral energy metabolism throughout the brain and that it might prove useful in clinical conditions in which a temporary reversible reduction in cerebral energy demand is desired.
