【Abstract】 Systolic intensity 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.更多还原
