三阴交是临床治疗中的常用穴之一

《甲乙经》云:“三阴交在内踝上三寸

骨下陷者中

足太阴、厥阴、少阴之会。”我们为了客观验证祖国医学有关三阴交与足三阴经交会的理论

为针灸临床提供可靠依据

并探索观察针刺得气的客观指标。现对14例受试者

针刺三阴交得气前后脾、肝、肾及非经部位的冷光信息作了69人次观察比较

结果如下: 方法一、仪器:详见前文

要点如下: 选用高灵敏度的光电倍增管做探测器

接收经穴不断发放的超微弱冷光信息

再经一系列的放大甄别

由记录仪自动描其发光On 14 subjects by 69 experiments

it was found that before needling

the intensity of luminescence of Yinbai

Dadun

Yungquan and Nei Zhi- yin (3 mm by the inner side of the nail of little toe) remained constant for a definite duration. During needling at the acupoint Sanyinjiao

when a definite needling sensation was to be elicited

the luminescence of all these acupoints increased prominently; whereas at the sites of non- acupoint

it remained unchanged. Statistically

there was significant dif- ference in luminescence between the non-acupoints and the Jing points of the three channels (i.e. Spleen

Liver and Kidney); there was also stron- ger luminescence at Yinbai of Spleen Channel in comparison with the Jing points of Liver and Kidney channels. This result provides evidence that Sanyinjiao

which

according to the classical theory of meridian

belongs to the channel of Spleen

is the "Meeting" point of the three ch- annels(i.e. Spleen

Liver

Kidney). This experiment provides also a quantitative method to determine objectively the needling sensation.
