説明
We studied 35 patients with active inflammatory skin diseases, measuring the levels of lipidperoxides and of the oxygen radical scavenging enzyme superoxide dismutase (SOD) in biopsy specimens of skin lesions. Lipidperoxide levels were markedly elevated in all patients. In fifteen patients with disease that was severe and highly resistant to therapy, SOD activity was only slightly increased, in comparison with normal controls. In contrast, in the twenty patients with mild disease that responded well to therapy, SOD activity was markedly elevated. The ratio of lipidperoxide levels to SOD activity was thus an accurate prognostic indicator, being elevated only in the group not responding to treatment. These findings suggest that the severity of allergic inflammatory skin disease and/or the response to treatment may in part be governed by the degree to which the patient's SOD activity is up-regulated in response to the generation of tissue-damaging substances such as lipidperoxides. Interestingly, our studies revealed the SOD activities of both normal and inflamed skin to be unexpectedly high; our data suggest that SOD plays a critical role in protecting the skin from the effects of oxygen radicals and ultraviolet light.
