Study of Danshen Yin on lipid-lowering mechanism in hyperlipemia model rats
Objective,2,To explore the effect and mechanism of Danshen Yin on lipid metabolism in rats with hyperlipidemia induced by long-term feeding with high-fat diet.,Methods,2,Totally 70 Wistar rats were randomly divided into basic group (,n,=14 ) and high-fat group (,n,=56 ). The rats in the basic group were fed with basic diet, and the rats in the high-fat group were fed with high-fat diet. The blood lipid level of the animals was measured in the eighth week. The rats in the basic group met the requirements were taken as the blank group. According to body weight and blood lipid levels, the successful modeling rats in the high-fat group were randomly divided into model group, simvastatin control group (0.004 g/kg ), high-dose Danshen Yin group (3.6 g/kg crude drug ) and low-dose Danshen Yin group (0.9 g/kg crude drug). Four weeks after administration, the blood lipid biochemical indexes (TC, TG, HDL-C, LDL-C) and the levels of lipid metabolic enzymes (HL, LCAT, PLTP) in plasma were detected and the pathological morphology of liver tissue was observed by HE staining.,Results,2,Compared with the model group, the plasma contents of TC, TG and LDL-C in high-dose Danshen Yin group were decreased (,P,<,0.05), while the content of HDL-C was increased (,P,<,0.05), and the plasma contents of TC and TG in low-dose Danshen Yin group were decreased (,P,<,0.05). HL content in plasma of rats in high-dose and low-dose Danshen Yin groups was increased (,P,<,0.05,P,<,0.01). The contents of LPL and MTP in liver tissues of rats in the high-dose and low-dose Danshen Yin groups were increased (,P,<,0.05), and the content of HMG-coA reductase was decreased (,P,<,0.05). Both Danshen Yin groups could significantly improve the pathological morphology of liver tissue in hyperlipidemia model rats, and the effect of high-dose Danshen Yin group was more obvious than that of low-dose Danshen Yin group.,Conclusion,2,Danshen Yin has significant lipid-lowering effect, and its mechanism may be related to the effect of Danshen Yin on lipid absorption, synthesis, transportation and metabolism.
