    Abstract:
    OBJECTIVE: To study the effect of Banxia Baizhu decoction on the spontaneously hypertensive rats and its possible mechanism. METHODS: Male SHRs of 6 weeks old were randomly and equally divided into two groups, the control SHR group and the group treated with BXBZTMD, the treated group were treated with BXBZTMD orally for 18 weeks, the control SHR group and normotensive WKY group were fed with the same amount of distilled water. Rats' blood pressure was measured through carotid artery catheterization, and protein of kidney tissues was analyzed by two-dimensional electrophoresis after extraction and purification. Different protein spots expressed significantly which were anlyzed by PDQuest software were then identified by MALDI-TOF/TOF MS. The protein expressions of peroxidase 2 and Cu-Zn superoxide in kidney were determined by Western blot. RESULTS: Compared SHR with WKY, 12 protein spots were changed. BXBZTMD could adjust kidney protein expression such as Cu-Zn superoxide dismutase, peroxidase 2 and may change kidney protein expression such as the alpha-beta-crystallin, which were closely related to oxidative stress. These discoveries of the target proteins suggested that BXBZTMD had curative effect by anti-oxidative stress. CONCLUSION: Oxidative stress plays an important role in the process of hypertensive renal injury. BXBZTMD can play a therapeutic role to oxidative stress. The discovery of the target protein provides a theoretical basis for the mechanism of the therapeutic effect of BXBZTMD.
