【摘要】 应用电生理学方法，观察到微量Ｐ物质或组胺注于大鼠背部足太阳膀胱经的＂肝俞＂至＂胆俞＂一段的皮下部位，可以引起外周感觉神经末梢的传入放电明显增多。表明Ｐ物质和组胺可能是经脉线上传递信息的化学物质。更多还原

【Abstract】 It was found by electrophysiologic method that subcutaneous injection of a trace of substance P or histamine into points "Ganshu" (BL 18)and "DanShu"(BL 19)of Bladder Chancel of Foot-Taiyang on the back of rats induced an increase of the afferent discharge in the endings of peripheral sensory nerves.It is indicated that substance P and histamine may possibly be mediators of information transmission along the channels and collaterals.更多还原
