【摘要】 本文在离体状态下观察P物质对不同性激素状态兔输卵管峡部平滑肌活动的影响。动物分成动情组、间情组、去卵巢组。实验结果:(1)P物质对间情兔输卵管峡部平滑肌的收缩有明显的抑制作用。(2)P物质对动情兔和去卵巢兔输卵管峡部平滑肌的收缩没有影响。结果表明P物质对不同性激素状态下的兔输卵管峡部平滑肌的作用不一致。更多还原

【Abstract】 The effect of substance P (SP) on the activities of oviductal isthmic smoothmuscle in rabbits was studied. Rabbits were divided into estrous, diestrous andovariectomized groups. The results were as follows: (1) SP suppressed the acti-vity of the oviductal isthmic smooth muscle in diestrous rabbit (P<0.05). (2) SPdid not suppress the activities of the oviductal isthmic smooth muscles in estrous andovariectomized rabbits (P>0.05).更多还原
