Abstract
The free radical theory of aging was introduced in 1956 by Denham Harman. This aging theory proposed that normal aging results from random deleterious damage to tissues by free radical and supplying antioxidant lead to decrease oxidative damage, inhibit aging process. In this study, we investigated antioxidantive effects of four Korean constitutional prescriptions for 'Soum' constitution - Palmulgunjatang(Y1), Sipyimiguanjungtang(Y2), Osuyubujayijungtang(Y3) and Seungyangyikkibujatang(Y4). Antioxidative activity of this prescriptions was examined by 1,1-diphenyl-2-picrylhyrdazyl radicals, superoxide anion radicals, peroxyl radical, hydroxyl radical scavenging effects and erythrocyte hemolysis inhibitory effects. Y2 and Y3 were shown to have relatively high antioxidative activity on this methods. In additions, result of the cytoprotective effects of Korean constitutional prescriptions agianst 2,2'-azobis(amidinopropane) dihydrochloride (AAPH), a free radical initiator, induced cytotoxcity in human hepatoblastoma cell line was similarly obtained. On the basis of this result, we assayed the antioxidative effects of Y2 and Y3 on experimental oxidative damage, induced in mouse by 100mg/kg AAPH. Male ICR mouse were given oral administration of 500mg/kg Y2 and Y3 for 4 weeks. Thiobarbuturic acid reactive substance (TBARS) and protein degradation level in liver, plasma and brain as index of oxidative damage were decreased and thiol compound, total antioxidant status in plasma were increased by Y2 administration. But, Y3 injected group was decreased only protein degradation level in brain. Also, glutathione, a potent water-soluble endogenous antioxidant, concentration was increased by Y2 and Y3 administration in liver and brain. However, superoxide dismutase and catalase activity as a major antioxidative enzyme in vivo were not shown change by Y2 and Y3 administration. On the basis of these result, Y2 have an antioxidative effects on both water-soluble fraction and lipid-solube fraction in cell and tissues. But, Y3 has a lower antioxidative effects on lipid-soluble fraction than Y2 in cell and tissues. These results suggest that Y2 has a antioxidative effects by protect the tissue against oxygen free radical mediated oxidative damage and Y3 has a limited antioxidaitve effects on water-soluble fraction in vivo. Therefore, we make report that Y2 is more effective prescriptions for anti-aging or therapeutics of diseases.
