title: [The effect of gamma-hydroxybutyric acid on the biosynthesis of macromolecules and metabolic paramagnetic centers in hepatocytes in acute radiation injury].
abstract: It has been shown, that the single injection of gamma-hydroxybutyric acid (GHBA) (100 mg/kg) to mice 30 min before irradiation (6 Gy) prevents whole-body irradiation-induced inhibition of DNA at early post-irradiation period. GHBA stimulates the biosynthesis of macromolecules at 1-2 days after irradiation. GHBA also prevents the increase in the degree of reduction of the mitochondrial and microsomal electron transport chains at early post-irradiation time (up to 2 h.), that takes place only under irradiation. It means, that GHBA inhibits the production of O2 radicals, which induce lipid peroxidation processes at post-irradiation period.
