title: [Characteristics of energy metabolism in the tissues of lake frogs and certain reptiles during prolonged deep hypothermia].
abstract: A week hypothermia (2-4 degrees C) does not cause a considerable decrease in content of glycogen in the liver, muscles, brain tissues of Lacerta strigata, Natrix tessellata and Rana ridibunda. In Eremias arguta pangolins the level of glycogen in the liver and muscles under these conditions is twice as low. Prolongation of hypothermia till three weeks causes a 4-fold decrease in the polysaccharide level in the liver of Eremias arguta and Lacerta strigata. The content of nonesterified fatty acids in blood under hypothermia (especially of three-week one) considerably exceeds the normal level. The content of lactic acid in tissues is two-three times as high under prolonged hypothermia, in the reptile muscles creatine phosphate accumulates in high amounts.
