The purpose of this study was to examine the effect and beta-endorphin level as conventional transcutaneous electrical nerve stimulation (TENS) application on acupuncture paints. Twelve healthy adult male volunteers were participated in this study. The subjects were assigned to TENS group (n=6) and naloxone group (n=6). The LI 3 and M 10 meridian points of dominant arm were stimulated comfortably with 100 pps, 75{mu}s conventional TENS for 30 minutes. Experimental pain threshold measurement and plasma beta-endorphin level were detected before and after conventional TENS application. Experimental pain threshold increased significantly (p<.01) but plasma beta-endorphin level was not change in TENS group. Experimental pain threshold increased significantly (p<.01) but plasma beta-endorphin level was not change in naloxone group. In this study, the conventional TENS induced analgesic effect, and plama beta-endorphin level was not increase concomitantly with analgesia. These results suggest that the beta-endorphin did not involved in conventional TENS analgesia.
