Lipid Peroxidation and Antioxidase Activities on Hairless Mouse Induced by UYB Irradiation and Effects of Tannic acid
자외선B파로 유도된 Hairless mouse의 과산화지질 및 항산화효소활성도와 탄닌의 효과
Abstract
Inhibitory effects of tannic acid on the lipid peroxidation induced by UVB were investigated. Tannic acid was administered either topically or orally for 3 days to hairless mice, which were previously irradiated with UVB, and inhibitory effects of tannic acid were measured. The UVB was found to cause skin erythema and hemolysis. When tannic acid was administered either topically or orally, hemolysis was decreased. After the skin was irradiated by UVB, the production of malondialdehyde was significantly decreased in erythrocyte and skin tissue, and the activities of SOD and catalase were significantly increased in plasma and skin tissue. In case of oral treatment, catalase activity was not significantly increased. The inhibitory effects of tannic acid on malondialdehyde production, SOD inhibition and catalase inhibition were more prominent in orally administerd groups than in topically administerri groups. However, the difference between two groups was not statistically significant. In conclusion, tannic acid decreased lipid peroxidation possibly by free radical scavenger action. The route of administrations, topical or oral, did not affect the antioxidative activity of tannic acid.
