To investigate the effects of the traditional Chinese medicines, Kuei-lu-erh-hsienchiao and Chia-wei-hsiao-yao-san, on the cardiovascular systems of mimic menopausal rats, five groups were formed: group 1 (the control group) was given a sham operation and received distilled water, while groups 2, 3, 4 and 5 were ovariectomized and received distilled water, Kuei-lu-erh-hsien-chiao, Chia-wei-hsiao-yao-san and 17-β-estradiol, respectively, for 4 months. Our results demonstrated that the mean

These data suggest that there might be some estrogen-like substances in Kuei-lu-erh-hsien-chiao. However, the function of these estrogenlike substances was unknown. The mean differences of the triglyceride (TG) levels, highdensity lipoprotein cholesterol (HDL-C) levels, low-density lipoprotein cholesterol (LDL-C) levels, and the ratios of TC/HDL-C and LDL-C/HDL-C in groups 1, 3, 4 and 5 were not significantly different from those in group 2. The mean differences of the total cholesterol (TC) levels in group 5 were significantly higher than those in group 2 (p < 0.05), but no obvious difference of the TC levels was found between groups 2 and 4. Nevertheless, the mean differences of the homocysteine (Hcy) levels in groups 4 and 5 were statistically lower than those of group 2. Therefore, administration of Chia-wei-hsiao-yao-san declines the Hcy levels in OVX rats and does not affect the TC levels in these animals. In conclusion, our results indicate that Chia-wei-hsiao-yao-san shows a more profound effect than 17-β-estradiol in the prevention of atherosclerosis in these OVX rats.
