The stimulative effect of supracutaneous electroacupuncture on human skin and its analgesic effect on rats

The stimulative effect of supracutaneous electroacupuncture using a blunt-tip electrode on 120 points of human skin was observed in 12 healthy volunteers. A comparison of stimulation by the more expensive supracutaneous instrument specifically designed for this treatment and that of the more conventional transcutaneous electroacupuncture instrument, modified by use of a blunt-tip, belt-type electrode instead of the traditional electro-needle, showed similar therapeutic effects. An animal experiment, using the rat tail flick analgesia method to compare supracutaneous electroacupuncture, showed that the pain threshold was raised by both types of electroacupuncture, with both having an optimal stimulation time of 10–20 minutes. The percentage of change in maximum pain threshold was 206.6% for supracutaneous electroacupuncture at 7V and 175.4% for transcutaneous electroacupuncture at 2V.     

精神分裂症阳、阴性症状与其阳性家族史、脑器质性因素关系的探讨

本文收集了符合DSM-Ⅲ-R诊断标准的466例精神分裂症患者的资料,发现有27.5％病人有精神病的阳性家族史,17.8％病人有假定的器质性因素。把精神分裂症的阴性和阳性症状与其阳性家族史和假定的器质性因素比较,发现精神病的阳性家族史和假定的器质性因素与精神分裂症的阴性症状明显相关,而与阳性症状关系不大。这与国外研究的结果一致,支持阴性综合症和阳性综合症的病因不同这一假说。
