Effects of portulaca total flavone on proliferation of vascular smoothmuscle stimulated by PDGF-BB
摘要
Abstract
AIM: To study the effects of por tulaca total flavone (PTF) on proliferation in duced by PDGF-BB of rabbit aortic smooth mus cle cells (VSMCs) and explore its mechanisms.METHODS: The VSMCs of cultured organiza tion-adherence was induced to proliferate by PDGF-BB, and effects of PTF on VSMCs was tested by cell counting method and 3H-thymi dine (3H-TdR) incorporation test;The effect of PTF on cell proliferative cycle of VSMC was ob served by flow cytomytry technique;The intra cellular calcium concentration was investigated by fluorimetry.RESULTS: PTF inhibited the proliferation of VSMCs induced by PDGF-BB in a dose dependent manner, and DNA symthesis, the cells numbers of G1 /G0 phase were increased and that of G2/S phase were decreased markedly (P<0.01).CONCLUSION: Proliferation of VSMCs induced by PDGF-BB can be inhibited by PTF.The mechanisms may be related with di minished VSMCs [Ca2+]i.关键词
