The effect of Samyonjihwangtang(SJT) on th level of brain antioxidants was examined in aged rat. Samyongjihwangtang(SJT) is assed Cervi Pantiri-chum Cornu, Ginseng Radix to Yukmijihwangtang. The experimental groups were divided into three groups and treated as follows ; normal group(NC), Vt.E administrated group(PC), SJT administrated Group(SJT). From the purified microsome of brain tissue, those were measures the amounts of oxidant materials like malonaldehyde(MDA) and H_2O_2, then activities of antioxidants enxymes like Superoxide dismutase, Catalase, NADPH-cytochrome P-450 reductase.
The results were as follows;
1. In TBA reaction to measure the amount of MDA, oxidant material of brain tissue of aged rat, both treated groups showed significant decrease.
2. In the formation of Hydrogen peroxide, the treated group(SJT) showed a little decrease.
3. The activity of Superoxide dismutase was increased significantly in both treated groups than normal group.
4. the activity of Catalase was increased significantly in both treated groups than normal group.
5. The activity of NADPH-cytochrome P-450 reductase in the treated group(SJT) showed a little increase.
According to the above results, it is suggested that Samyongjihwangtag(SJT) has some antioxidant effects on the tissue of brain.
