Abstract
Acupuncture and Radix Astragali aqua-acupuncture stimuli have long been used to cure human diseases. However, it still remains to be unkown on its action mechanism, physiolosical and biochemical aspects. Thus, many attempts were made to show the scientific background covering the above mentioned mechanisms. Most recent studies show that these tests improve blood circulatory system and increase leucocyte counts. In this study, we have applied the acupuncture stimuli to mouse Sinsu(BL-23), which is a stimulative point of oriental medicine, to see if cytokine such as IL-6 can be detected. Mice were treated with lipopolysaccharide(LPS) for inflammation induction, and then reverse transcriptase-polymerase chain reaction (RT-PCR) using each primer set was performed to trace the amounts of mRNA. The results are summarized as follows ; 1. IL-6 was not temporarily expressed in normal mice 15 min after the acupuncture was pulled out. But, it started to show a feeble expression at 30 min after the removal of acupuncture and it started to reduce at 1h. after the acupuncture was pulled out 2. IL-6 was specifically expressed in LPS-treated mouse 30 min after the acupuncture was pulled out. The transcriptional expressions of LPS-treated mice were more effective than those of normal mice at 30 min after the removal of acupuncture 3. IL-6 was not temporarily expressed in normal mice 15 min after Radix Astragali aqua-acupuncture. But it expressed most highly at 30 min, and the transcriptional expressions of IL-6 was continued to 3 h. 4. IL-6 was not expressed in all the time after Radix Astragali aqua-acupuncture in LPS-treated mice. Therefore, a follow-up of cytokine IL-6 can be used not only a basis of the effect of acupuncture and Radix Astragali aqua-acupuncture but a diagnosis giude through the immunological action of thats. And, it is suggested that cytokine's expression by Acupuncture and Radix Astragali aqua-acupuncture stimulation should be continuously elucidated.
