Research for specificity of meridian and acupoint on acupuncture medicine.

针灸医学是建立在经络和穴位系统之上的。但目前对其性质尚不清楚，认为经络穴位系统不是由特定的组织组成，而是由功能系统组成。经络穴位系统的特殊作用是从皮肤-内脏反射的框架中现象学地研究的。用超声层析机拍摄胆囊层析片，用图像处理机检测其面积。刺激穴位有久代、谷野、直津、潭鱼、小悟空和非穴位。分别给予针刺或电针刺激6~10分钟。结果如下：1)久代增大了胆囊截面积；2)谷野缩小了胆囊截面积；3)悟空增大或缩小了胆囊截面积；4)结节、潭鱼和非穴位对胆囊截面积无明显影响，提示经穴系统可能具有特定的作用。

Acupuncture and moxibusion medicine is founded on the meridian and acupoint system. but its nature is nuknown at present.It is considerd that the meridian and acupoint system dose not consist of specifc tissues,but consist of functional system.The specific effects of the meridian and acupoint system was phenomenalogically investegated from a frame of cutaneous-viscral refex.The target organ was a gallbladder. Tomogram of gall-bladder was taken by ultrasonic tomograph ,its area was examined by image processor. Stimulated points were Kyukyo,Tanno,Jitsugetsu,Tanyu,Gokoku,and nonacupoint. They were stimulated by acupuncture or electroacupuncture for 6-10 minutes. And Effects of acupuncture on sectional area of gallbladder that was reduced by egg were examined,too.Results are as follows.1) Kyukyo enlarged sectional area of gallbladder.2) Tanno reduced sectional area of gallbladder.3) Gokoku enlarged or reduced sectional area of gallbladder.4) Gitsugetsu,Tanyu and nonacupoint could not change sectional area of gallbladder remarkably.These results suggested that meridian and acupoint system have the specific effects probably.
