title: [The protective effect of pantothenic acid derivatives and changes in the system of acetyl CoA metabolism in acute ethanol poisoning].
abstract: Calcium pantothenate (CaP), calcium 4'-phosphopantothenate (CaPP), pantethine, panthenol, sulfopantetheine and CoA decrease acute toxicity of acetaldehyde in mice. All studied compounds diminish duration of the narcotic action of ethanol--ET (3.5 g/kg intraperitoneally) in mice and rats. In the latter this effect is realized at the expense of "long sleeping" and "middle sleeping" animals. CaP (150 mg/kg subcutaneously) and CaPP (100 mg/kg subcutaneously) prevent hypothermia and a decrease of oxygen consumption in rats induced by ET administration. Combined administration of ET, CaP and CaPP leads to a characteristic increase of acid-soluble CoA fractions in the rat liver and a relative decrease of acetyl CoA synthetase and N-acetyltransferase reactions. The antitoxic effect of preparations of pantothenic acid is not mediated by CoA-dependent reactions of detoxication, but most probably is due to intensification of ET oxidation and perhaps to its elimination from the organism.
