针术与深部感受器放电反应的关系

在29只兔上观察到每类深部感受器均可对所用针术产生放电反应;针刺影响感受器的有效刺激点。说明针刺对感受器的有效刺激主要是针刺的压力、牵拉和振动等所产生的使感受器发生形变的应用作用。认为胀与胀痛,包括酸感为主的手针针感主要是兴奋了深痛感受装置。

THE RELATIONS BETWEEN ACUPUNCTURE MANIIPULATIONS AND RESPONSIVE DISCHARGES OF DEEP RECEPTORS

Twinty-nine rabbits were used.The spindle,tendon organ,light and hea-vy pressure receptors in medial gastrocnemius muscle were identified by reco-rding discharges of single afferent fiber in medial gastrocne mius nerve fromfine filaments by dissection.The discharge patterns of the receptors respon-ding to the manipulations,i.c.lift and thrunst,twist and twirl,rotate,scra-pe flick the needle and finger-pressure were observed.Data at 85 units werecollected totally.Every type of deep receptor can react to any manipulation.The dischargepatterns of different receptors were alike when stimulated with same manipu-lation,but there were different patterns while varying manipulations actingon the same receptor.These are due to the movement forms,the force amo-unt,the time duration of the manipulations.All these facts are nearly thesame as in cutaneous receptors.Acupuncture effect on deep receptors was not limited to one point butwithin a certain area,namely distant effect existed.The area size variedfrom receptor to receptor and from manipulation to manipulation.Because of the distant effect on receptors by acupuncture,and the loseof responsibility in units when receptor destroyed,we suggest that effectiveacupuncture stimulation is induced mainly due to the receptor deformation,whichis caused by the stress from pressure,stretch and vibration of acupuncture.In view of the needling sensation is closely related to the curativeeffects,the receptors dealing with needling sensation are analysed according tothis series works and other facts,we further advance the opinion that the re-ceptors of deep pain are the chief material foundation to induce the sensationof hand needling.
