[Glucose content in the tissues of susliks and rats of different ages under hypothermia]

A short-term cooling of adult rats and gophers up to 30, 25 and 20 degrees C is accompanied by a rise of the glucose level in blood. No dependence is found between lowering the body temperature drop and degree of glycaemia. Prolongation of hypothermia of 30 and 20 degrees C up to 3 h causes (as compared to the control) a decrease in the glucose amount in blood of gophers but not in the rats. The cooling of the eye-opening, month and adult rats up to 20 degrees C is accompanied by a significant increase in the content of glucose in the brain and skeletal muscles. Simultaneously in the eye-opening and adult animals, contrary to the month ones, the level of glucose in the liver and blood rises. The content of glucose in the brain of the normothermal gophers (61.2 mg.) is 3,4 times as high as in the rat brain. At all the studied stages of artificial hypothermia as well as at 15 and 30-day hibernation (5 degrees C) the amount of glucose of the gopher brain remains at a relatively high level (41.6-101.5 mg%).
