title: [The effect of gamma-hydroxybutyric acid on the reaction rate of phosphate-containing metabolites in the rat brain during ischemia estimated from (31)P-NMR spectroscopic data].
abstract: Protective effects of gamma-hydroxybutyric acid on bioenergetic reactions were studied in brain of rats with ischemia using 31P-NMR spectroscopy in vivo. Intraperitoneal preadministration of gamma-hydroxybutyric acid at a dose of 400 mg/kg within 30-40 min before ischemia led to a decrease in the ATP pool in ischemic brain tissue, to alteration in the PCr/ATP ratio in the 31P-NMR spectrum, to prevention of Pi concentration increase and to increase in the intracellular acidosis development rate. Possible mechanisms of the gamma-hydroxybutyric acid effects on bioenergetic reactions in nervous tissue during ischemia are discussed.
