正文 無患子皂苷對自發性高血壓大鼠AngⅡ_p38MAPK 通路介導的炎症反應與心肌肥厚的影響(3 / 3)

[Abstract] Objective: To investigate the effects of sapindus saponins on myocardial inflammation mediated by Ang Ⅱ/p38MAPK signal pathway and cardiac hypertrophy in spontaneously hypertensive rats . And also to explore the correlation of cardiac hypertrophy and inflammation. Method: Thirty,two 16,week,old spontaneously hypertensive rats (SHR) were randomly divided into four groups, one with placebo as model group, one with captopril tablets(27 mg·kg-1)as positive control, one with low,dose sapindus saponins(27 mg·kg-1), one with high,dose (108 mg·kg-1). And another eight healthy Wistar,Kyoto strain(WKY) rats were used as the normal group. The animals were treated for eight weeks, and the indicators detected were as follows: ①left ventricular mass index (LVMI); ②the content of AngⅡ and hs,CRP in plasma were determined by ELISA;③the protein expression of AT1R and VEGF were determined by immunohistochemical method; ④the protein expression of p,p38MAPK in myocardial cells was determined by Western blot. Result: Sapindus saponins reduced LVMI, and blocked the expression level of AngⅡ, AT1R, p,p38MAPK, VEGF and hs,CRP in myocardial tissue. Vs the SHR model group, there were significant differences (P
