Abstract:
Objective To observe the effect of mature rehmannia extract on platelet derived growth factor (PDGF) and b-cell lymphoma-2 (bcl-2) 2 in myocardial tissue of rats with myocardial infarction.Methods A total of 30 healthy SD rats were randomly divided into blank group,model group and rehmannia glutinosa group with 10 rats in each group.Myocardial infarction models were established in rats of model group and prepared Rehmannia glutinosa group.The rats in the prepared rehmannia glutinosa group were subcutaneously injected with the extract of the prepared Rehmannia glutinosa 4 g/kg.The rats in the blank group and the model group were subcutaneously injected with the same volume of saline.Once a day for 15 days.The cardiac function was measured by echocardiography in rats.The HE staining was used to observe the histopathological changes of myocardium.The levels of PDGF and Bcl-2 in myocardium were detected by ELISA.The levels of vascular endothelial growth factor (VEGF),basic fibroblast growth factor (BFGF) and CD34 protein were detected by immunoturbidimetry.Results Compared with the model group,the levels of LVDd,LVDs,LVEDs and LVESV in the Rehmannia glutinosa group were significantly decreased (P＜0.05) and LVEF was significantly increased (P＜0.05),while the levels of PDGF (0.53 ± 0.02 g/ml vs.0.35 ± 0.01 g/ml),Bcl-2 (1.04 ± 0.20 g/ml vs.0.84 ± 0.12 g/ml),VEGF (85.24 ± 12.45 pg/ml vs.65.26 ± 10.06 pg/ml),BFGF (86.27 ± 6.56 pg/ml vs.62.26 ± 4.37 pg/ml) and CD34 (102.36 ± 10.52 pg/ml vs.26.37 ± 3.94 pg/ml) in in the Rehmannia glutinosa group were significantly increased (P＜0.05).Conclusions The Rehmannia glutinosa extract can improve the cardiac function of rats with myocardial infarction,Promote the formation of new blood vessels and improve myocardial damage.
