Intraperitoneal administration of extracts of the small intestine epithelium of hibernating ground squirrels (C. Parryi Rich., C. undulatus) to white mice caused a decrease in oxygen consumption by 50-80%, the 5.5-14.0 degrees C drop in body temperature, inhibition of the muscle shivering thermogenesis, a decrease in heart rate, reduction of locomotor activity, development of hypnogenic effect and a closer dependence of body temperature on environmental fluctuations. The effects lasted for 30-40 hrs. Extracts from the small intestine tissue of non-hibernating ground squirrels caused insignificant changes of these parameters.
给小白鼠腹腔注射冬眠地松鼠（C. Parryi Rich.、C. undulatus）小肠上皮提取物后，耗氧量降低了50 - 80%，体温下降了5.5 - 14.0摄氏度，肌肉颤抖产热受到抑制，心率降低，运动活性减弱，产生催眠作用，且体温对环境波动的依赖性增强。这些作用持续了30 - 40小时。非冬眠地松鼠小肠组织提取物对这些参数的影响不显著。
