Study on effect of Hegu laser He-Ne iradiation on some peripheral blood indexes

ABSTRACT

20 healthy male students from 20-25 years of age were studied on the changes of peripheral blood indexes after the exact Hegu laser He-Ne irradiation with intensity 130 mW/cm2 for 2 minutes/point. 10 (changed most clearly) of 20 these students were irradiated laser outside the Hegu (1cm far from the Hegu) as the control group. Before irradiating, after laser 10, 30 minutes, vein blood was taken to investigate the following indexes RBC, WBC, HGB, HCT, MCV, MCH, MCHC, PLT, NEUT/1, LYMPH/1, MDX/1, RDW-SD, MPV, P-LCR. The results showed that PLT, WBC, LYMPH/1 reduced markly after 10, 30 minutes (p<0.05); there were no differences of the other (RBC, HGB, HCT, MCV, MCH, MCHC, NEUT/1, RDW-SD, PDW, P-LCR) between before and after laser irradiation. There was no differences between before and after outside-Hegu laser He-Ne irradiation; the time when the peripheral blood indexes changed more clearly is at the 30th minute after irradiating.
