The present study investigated the effect of ChumDoSunBup (CDSB) Qi-training (Korean traditional psychosomatic training) on cellular immunity. The acute change of natural killer cell activity were determined at three time, before (-10min), immediately after, and I hour after the Qi-training. Assay for cytotoxicity were analyzed by using a non-isotopic method which measures the LDH release from tumor target cell. NK cell subsets (CD57) were examined by flowcytometry. The increase in NK cell cytotoxicity observed immediately after Qi-training. NK activity was significantly increased more than 1.6times compared to the basal value of before Qi-training (P<0.01). The increased level of NK activity was recovered to basal level within two hour. The resting (sedentary) subjects did not show any change of specific lysis for the resting 2 hours. There was no change in the number of NK cell subset after Qi-training. And no correlation between the NK cell number was found. There data suggest that CDSB changes of NK cell subset, may exert a positive immunological effect in man. |
