摘要 目的:观察苦参碱(Matrine,Mat)对U937细胞及人脐静脉血管内皮细胞(HUVECs)增殖的影响。方法:采用体外培养技术,通过细胞形态、MTT实验、细胞周期测定观察Mat对U937细胞及HUVECs增殖的影响。结果:Mat(0.2~0.5mg/mL)作用24h后对U937细胞均有增殖抑制作用(P〈0.05或P〈0.01),在该浓度范围内呈剂量和时间依赖性,其作用U937细胞48h的半数抑制浓度(IC50)约为0.4mg/mL,有效作用时间为1d;Mat(0.1~0.5mg/mL)作用24、48、72h后对HUVECs增殖无明显抑制作用,亦无剂量和时间依赖性(P〉0.05);Mat(0.2~0.5mg/mL)作用U937细胞48h后,S期细胞比例增加,细胞发生S期阻滞(P〈0.05或P〈0.01);Mat(0.1~0.5mg/mL)作用HUVECs 48h后,对细胞周期无明显影响(P〉0.05)。结论:一定浓度Mat对U937细胞具有增殖抑制作用,呈时间-剂量依赖关系。Mat在一定浓度和时间下不能抑制HUVECs增殖,对其细胞周期亦无明显影响。 AIM: To observe the proliferative effects of matrine on U937 cells and human umbilical vein endothelial cells. METHODS: The effects of matrine on U937 cells and human umbilical vein endothelial cells proliferation were observed by morphology, MTT and cell cycle detection. RESULTS: U937 cells treated with matrine at the concentration of 0.2 mg/mL to 0.5 mg/mL for 24 h were inhibited proliferation in a time and dose-dependent manner detected by MTT (P 〈 0.05 or P 〈 0.01) and increased at the S stage ( P 〈 0.05 or P 〈0.01). The half-inhibition concentration ( IC50 ) was 0. 4 mg/mL in U937 ceils compared with human umbilical vein endothelial cells (P 〉 0.05). HUVECs treated with matrine at the concentration of 0.1 to 0.5 mg/mL for 48 h showed no effect on cell cycle ( P 〉 0.05). CONCLUSION: Matrine has an inhibited effect on U937 ceils proliferation in a time and dose-dependent manner.
