 Abstract
Objectives : This study was intended to observe the changes in the expression of neurotransmitters, such as nNOS, NO and NE upon the needle insertion at varying depths at the connecting point. Methods : Needles were inserted into rats, on both left and right sides of the connecting point, including the LI6, SI7 and TE5 acupoints which are three yang meridians of the hand. After insertion, needles were retained for five minutes. Each acupuncture groups were treated acupuncture at each acupoint and at the depths of superficial, middle and deep layer. After the retention, blood was drawn via cardiac puncture, and tissues of each point near meridian vessels were extracted to examine the changes in the expression of nNOS, NO and NE. Results : In terms of the effect in nNO production, there was a significant increase only in the middle and deep layer at SI7 acupoint, but there was no significant change in the expression of NO. Regarding the formation of norepinephrine within tissues, the middle layer on LI6 acupoint, the middle layer and the deep layer on TE5 acupoint showed a significant increase, while production of plasma norepinephrine was significantly decreased at the middle layer and the deep layer on LI6 acupoint and the deep layer on SI7 acupoint. Conclusions : The effect of needles applied at the connecting point of three yang meridians on the activities of nNOS, and NE could be observed, and it can be induced that the effect of needle stimulation on disrupted nervous system can be examined through additional researches based on this one.
