Abstract

To detect the effect and mechanism of procyanidin foom vaccinium (PC) on myocardial fibrosis in rats. The myocardial fibrosis model in rats was built by subcutaneous injection of 5 mg x kg(-1) x d(-1) of isoprenaline (Iso) for 7 days in vivo while intragastrically administrating PC 100, 200 and 400 mg x kg(-1) x d(-1) for 14 days. Following the model was established, myocardial indexes (heart weight/body weight, HW/BW and left ventricalar weight/body weight, LVW/BW) were measured. Besides, angiotensin II and I , III collagen quantification levels in blood serum were determined respectively by ELISA. The change in the content of nitric oxide (NO) in blood serum was determined with colorimetry. The content of malondialdehyde (MDA) in left ventricle was assayed with spectrophotometry. The contents of lactate dehydrogenase (LDH) and creatine kinase (CK) in blood serum were detected with automatic biochemistry analyzer. Compared with the control group, the myocardial indexes, the contents of I , III collagen quantification, angiotensin II in blood serum and malondialdehyde in left ventricle were markedly increased and the content of nitric oxide in blood serum was decreased, the contents of lactate dehydrogenase and creatine kinase ...Continue Reading
