[Influence of hyperthermia and protective effect of ionol and carbon dioxide gas on ATP, ADP and AMP content of the rat brain].

It is shown that the amount of ATP in rats under hypothermia up to heat stroke lowers and that of ADP and AMP somewhat rises. Ionol administration normalizes the ATP level and increases the ADP and AMP contents. Inhalation of CO2 and especially administration of ionol contribute to a higher resistance of the animals to hyperthermia.
