The purpose of this study was to determine the effects of laser Irradiation on Human plasma beta-endorphin levels, by treating with low level helium-neon (He-Ne) and Infrared(lR) laser. The Laser was fixed frequency of 2400Hz by continuous scanning and irradiating time was 8 minutes each point. Blood samples were taken at before, after, after 15min’’s treatment and Plasma beta-endorphin was measured by radioimmunoassay. The samples for this study were 6 normal subjects(3male, 3female). The data were analyzed by paired t-test, one-way ANOVA and simple regression. The results of this study were as follows : 1. The human plasma beta-endorphin levels were noted as significant increase in after-treatment (22.84{pm}10.63pg/ml) as compared with before-treatment (16.96{pm}9.23pg/ml) and significant increase in after 15min’’s (27.27{pm}8.81pg/ml) as compared with after-treatment (p<0.05). 2. There were no significant changes in plasma g-endorphin levels between male and female. 3. The human plasma beta-endorphin levels were high associated in between session reliability (p<0.05).
