In order to study the effects of Guibitanggamibang on blood pressure and hyperlipidemia, experimental study were performed on hypertension in normal and SHR rats, and on hyperlipidemia induced by Triton WR-1339 in normal rats. Also the level of total cholesterol, triglyceride, LDL-cholesterol, HDL-cholesterol, phospholipid and transaminase(GOT, GPT) were measured. The results are summarized as follows: 1. After Guibitanggamibang was given to normal rats, the results showed that inhibitory effects on blood pressure and heart beat were not statistically significant. 2. After Guibitanggamibang was given to SHR rats, the results showed that inhibitory effects on blood pressure were statistically significant. 3. In the model of hyperlipidemia induced by 2% cholesterol food, Guibitanggarrubang had significantly-decreasing effects on total cholesterol, triglyceride, HDL-cholesterol, LDL-choleste rol, Transaminase(GOT, GPT) level in serum. 4. In the model of hyperlipidemia induced by Triton WR-1339, Guibitanggamibang had significantly-decreasing effects on total cholesterol, triglyceride, LDL-cholesterol, phospholipid, Transaminase(GOT, GPT) level in serum. 5. In the model of hyperlipidemia induced by Triton WR-1339, Guibitanggamibang had no significant effects on HDL-cholesterol level in serum. These results show that Guibitanggamibang(歸脾湯加味方) has significant inhibitory effects on blood pressure and hyperlipidemia and that it could be clinically applied for hypertension and hyperlipidemia.
