ABSTRACT
OBJECTIVE: To study the effects of Anxin Granules on dyslipidemia in rabbits caused by high fat plus high cholesterol diet. METHODS: Thirty-two healthy New Zealand male white rabbits were randomly divided into 4 groups: normal control group, untreated group, Zhibituo Tablet-treated group and Anxin Granule-treated group. Rabbits in the normal control group were fed with regular chow, while rabbits in the other three groups were fed with high fat plus high cholesterol diet. Zhibituo Tablets and Anxin Granules were administered to the rabbits in Zhibituo Tablet-treated group and Anxin Granule-treated group at a daily oral dose respectively. At the end of the 10th week, the levels of serum total cholesterol (TC), triglycerides (TG), high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C), apolipoprotein A(1) (ApoA1) and apolipoprotein B (ApoB) were tested in each group, and the ultrastructures of the aorta were also observed by an electron microscope. RESULTS: Anxin Granules could reduce the levels of TC, TG, LDL-C and ApoB. The results observed by electron microscope showed that, as compared with the untreated group and the Zhibituo Tablet-treated group, the atherosclerosis of aorta in the Anxin Granule-treated group was lighter. And it was found that there were few lipid droplet vacuoles in cytoplasm of the endothelial cells, and various cell organs and elastic membrane were existed, but no lipid droplet vacuoles in cytoplasm of the medial smooth muscle cells. CONCLUSION: Anxin Granules can regulate the metabolism of blood lipid and inhibit the formation of atherosclerosis caused by hyperlipidemia in rabbits.
ABSTRACT
Objective: To observe the effect of Ruxiankang (RXK) Capsule (Radix Bupleuri, Poria, Rhizoma Atractylodis macrocephalae, Radix Angelicae Sinensis, Radix Paeoniae Alba, Rhizoma Cyperi, etc.) on mammary gland and sex hormone of rat with mastoplasia. Methods: After benzoate estradiol and progestogen were injected into rats for 30 days the mastoplasia model was made, the model rats were treated with tamoxifen and RXK Capsule for 30days, and injected estradiol at the same time. Results: RXK Capsule and tamoxifen could significantly inhibit HMG rat's mammary gland swell, reduce quantity of lobule alveolus in mammary glands and secretion ( P
