[Characteristics of energy metabolism in tissues of edible frog in different seasons].
The lowest content of glycogen (2540 mg%) in the vigil frog liver tissue is found in March, soon after hibernation, the maximum content (8000 mg%) is marked in November, before hibernation. In autumn the highest level of nonesterified fatty acids is observed in blood (0.33 muequiv./ml), that of creatine phosphate (64.3 mg%) and ATP (66.6 mg%) in the brain tissues. In December-January, in the period of a week an one-and-a-half month hibernation (2-4 degrees C) the content of glycogen in the liver is 5.5-3.2 times as low, in the brain tissues and femur muscles it increases. The content of glucose in the liver, blood, muscles (but not in the brain) also increase; the level of fatty acids in blood lowers slightly. The content of macroergic phosphates in the brain tissues becomes 5.4-2.1 times as low. Awakening does not lead to a decrease in the content of glycogen in the tissues, the content of fatty acids increased by 110%.
