【Abstract】 Serum lipid peroxied(LPO) levels and activities of superoxide dismutase (SOD) of erythrocytes were measured in 65 patients with systemic lupus erythematosus(SLE).Oxygen radicals (OR) levels were significantly increased in active SLE patients while SOD activities were markedly decreased,LPO levels were increased.The gradual increase in SOD activities and decline in LPO levels were observed in inactive patients after treatment with corticosteroid suggesting a reduced OR level.Ultroviolet light and some medications could stimulate neutrophils to generate excessive OR that could enhance the autoimmune reaction.更多还原
