摘要: 目的:探讨川芎嗪对脂多糖诱导大鼠肾小球系膜细胞增殖及细胞间粘附因子-1 表达的影响。方法:体外培养大鼠肾小球系膜细胞, 经脂多糖诱导后, 分别应用噻唑蓝(MTT) 比色法和流式细胞术检测细胞增殖抑制率和细胞周期的变化, 应用免疫细胞化学法检测细胞表面细胞间粘附因子-1 的表达。结果:川芎嗪呈剂量依赖性的抑制系膜细胞的增殖,并阻止细胞由G0/G1 期进入S 期;使系膜细胞间粘附因子-1 的表达水平明显减少。结论:川芎嗪能抑制大鼠肾小球系膜细胞增殖和降低细胞间粘附因子-1 表达水平。

Abstract: AIM: To investigate the effects of tetramethylpyrazine (TMP) on the proliferation of rat glomerular mesangial cells (GMCs) induced by LPS and the levels of intercellular adhesion molecule-1 (I CAM-1).METHODS: Different concentrations of TMP were put in the cultured rat GMCs in vitro after induced by LPS.Cell proliferation was assessed by MTT colorimetric assay and cell cycle was analyzed by flow cytometry.The levels of ICAM-1 were detected by immunohistology.RESULTS: The proliferation of MC induced by LPS was inhibited significantly by TMP with a dose-dependant manner.In the cell cycle, TMP increased the cells in G0/G1 phase and decreased the cells in S phase, and the ICAM-1 expression level was decreased.CONCLUSION: LPS-induced proliferation of MC is inhabited significantly by TMP.It blocks G0/G1 phase into S phase and inhibited the ICAM-1 expression.

Key words: tetramethylpyrazine, mesangial cells, proliferation, intercellular adhesion molecule-1
