Abstract

Some studies report that electroacupuncture(EA) boost natural killer cell(NK cell) activity. And also it is well known that hypothalamus is deeply related to effects of EA on analgesia. Some reports said that especially lateral hypothalamic area(LHA) is related to splenic NK cell activity. In order to investigate the relation between hypothalamus and effects of EA at ST36 point on NK cell activity of Spraque-Dawley rats. Lesions were made bilaterally at lateral hypothalamic area(LHA). And NK cytotoxities of normal and lesioned rats were measured with 51Cr release immunoassay after EA stimulation for 2 and 14 days. NK cell activity of EA group was significantly higher than sham group at 2nd, 14th day in normal rats. And LHA lesions abolished effects of EA on NK cell activity at 2nd day. But LHA lesions did not affect the effects of EA at 14th days. We also had an evidence that the decrease of NK cell activity was almost recoverd at 14th day. These results strongly suggest that LHA is deeply related to increase of NK cell activity induced by EA.
