The Effect of ILLLI on Peripheral Blood SOD, MDA in Psoriasis Treatment

摘要

Objective: To research the effect of Intravascular low level laser irradiation (ILLLI) on the SOD,MDA in the treatment of psoriasis. Method:47 patients suffering from psoriasis from five groups were treated by Intravascular low level laser irradiation (power:4-5mw,1h per day, period of treatment: 10 days). We checked the change of SOD,MDA peripheral blood in 10 normal people between pre and post treatment. Group A were treated by He-Ne laser combined with drug, group B were treated by semi-conductor laser combined with drug, group C were treated only by He-Ne laser, group D were treated only by semiconductor laser, group E were treated only by drug . Results: The levels of SOD in red cell of psoriatic patients from five groups after treatment were significantly lower than that of controlled group. The levels of SOD of them were significantly increased and nearly closed to that of controlled group; the levels of MDA in red cell of psoriatic patients from five groups after treatment were significantly higher than that of controlled group; the levels of MDA of them are decreased ,however, they were still not recovered to normal levels. Conclusions: ILLLI, both He-Ne laser and semiconductor laser, can activate SOD in psoriasis patients and enhance their ability of anti-oxidation.
