Abstract：Systolic in tensity of intestinum tenue of 47 Erinaceus europaeus in hibernation bout at low temperature stage and 53 ones in non-hibernation has been studied under different conditions, such as at different temperatures (11.5℃and 37℃), in vitro, and by supplying of adrenaline (Ad), acetylcholine(Ach), propranolol and atropine(Atr). The results showed that both in and out of hibernation, the intestinum tenue was basically motionless at 11.5℃, but at 37℃, its motional intensity in the hibernation bout at low temperature stage was obviously higher than that in the non-hibernation. Ad, Ach, propranolol and Atr could evidently improve the systolic intensity of intestinum tenue in the hibernation bout at low temperature stage when compared with that in non-hibernation.
