不同穴位电针对家兔闪光视网膜电图的作用

Effects of Acupuncture of Different Points on Flash Electroretinogram in Rabbits

本文将２４只家兔随机分为４组，即合谷组、三阴交组、昆仑组和对照点组，分别施以电针，采用视觉电生理方法，在针刺前后及针刺过程中每隔５ｍｉｎ记录闪光视网膜电图（ＦＥＲＧ）１次，观察针刺对ＦＥＲＧ的影响。结果表明，针刺合谷、昆仑组ａ、ｂ波振幅增加，三阴交组振幅下降；合谷、昆仑组ｂ波峰潜时缩短，而三阴交组峰潜时延后，针刺对照点对ａ、ｂ振幅及峰潜时均无明显影响。

In order to demonstrate the effect of acupuncture on retinal function, the experiment was performed on 24 albino rabbits,which were divided randomly into four groups I i. e, Hegu group, Sanyinjiao group, Kunlun group and control group. They received electroacupunctute of Hegu (LI4), ssanyinjiao (SP 6 ),Kunlun(BL 60) and control point respectively. Flash Electroretinogram (FERG) was recorded before and after acupuncture, and during acupuncture once each 5 min.The results showed that amplitudes of both a--and bwaves increased in the Hegu group and the Kulun Group,and decreased in the Sanyinjiao group. The implicit time of b-wave shorted after acupuncture in the Hegu group and the Kunlun group,and delayed in the Sanyinjiao group. However, the implicit time of a-wave did not have evident change in all the groups. Acupuncture of the control point did not have marked effects on the amplitude and implicit time of and b-waves.
