Abstract
Objective To explore the expression and mechanisms of MMP-9 in vascular remodeling of two-kidney and one-cliped hypertension rats. Methods Male Wistar rats were randomly divided into sham operation group( n = 10), two-kidney and one-clip model (2KIC) group ( n = 10) and telmisartan group ( n = 7 ). Telmisartan group were injected with telmisartan every day. The blood pressure was determined every week. The morphologic change of carotid artery and thoracic aorta was observed with HE stainning 8 weeks after treatment with telmisartan.Arteries was performed to evaluate the expression of MMP-9 with immunohistochemisty. Results The blood pressure,vessel wall,and the expression of MMP-9 in model group were significantly higher than that of control group.Telmisartan nearly normalized arterial pressure and suppressed all these changes. Conclusion MMP-9 was related to vascular remodeling and Telmisartan could regulate vascular remodeling in 2-kidney and 1-cliped hypertension rats by inhibiting the pathway of MMP-9. Key words: MMP-9 ; 2K1 C, Hypertension; Vascular Remodeling ; Telmisartan
