- Abstract: Aim To explore the effeet of puerarin (Pue) on aortic function and blood pressure in hyper-tensive mice induced by high-fat diet.Methods Thirty male mice were divided into five groups named as normal diet group ( Con ) , high-fat diet group (1)10), high-fat diet + low-dose puerarin group (20 mg 'kg-1 •(!"'), high-fat diet + medium-dose puera¬rin (40 mg • kg"1 • d ~1 ) group and high-fat diet + high-dose puerarin group (80 mg 'kg-1 • d~l).Hie mice were injected intraperitoneally with Pue for eight weeks.Body weight, blood pressure and blood glucose were measured.Serum was collected to detect blood lipid.Aortas were separated from aortic endothelial cells to test the vasodilative function.Aortic endotheli¬al cells from 1)10 mice were isolated to perform Iran-swell and cell proliferation experiments.Results I High-rlose puerarin treatment could reduce the body weight, body fat, blood glucose and blood pressure in obese mice ( P < 0.01 ) ; 2 High dose of puerarin could improve the vasodilative function of aortas com¬pared with those from 1)10 mice (P <0.01 ) ; (3) The migration ability of primary endothelial cells from 1)10 + Pue group was improved compared with that from 1)10 group (P <0.01 ).Conclusions Puerarin can significantly reduce blood pressure in obese mice in¬duced by high fat diet by improving the aortic diastolic function and endothelial cell proliferation and migra-tion.
