目的:研究并比较用于动脉重建手术的主要合成假体的细胞毒性,包括聚四氟乙烯(PTFE)和聚对苯二甲酸乙二醇酯(涤纶)。
材料与方法。在人脐静脉内皮细胞(英文:human umbilical vein endothelial cells,HUVEC)培养3代中,进行了MTS检测,用于实验室研究,利用细胞技术研究药物和医疗器械的细胞毒性。测试涉及使用MTS试剂,即3-(4,5-二甲基噻唑2-基)-5-(3-羧基甲氧基)-2-(4-磺苯基)- 2h -四唑;此外,还使用了吩嗪硫酸甲酯(PMS),其起到了电子结合试剂的作用。在实验中,细胞与聚四氟乙烯和涤纶在37℃,5% CO2含量下孵育24小时。在标准生长培养基中培养人脐静脉内皮细胞作为对照。经吩嗪硫酸甲酯存在时,内皮细胞线粒体脱氢酶将MTS降低为甲瓒,其中有蓝色染色。使用Stat Fax3200分析仪(microplate reader)Awareness technology Inc.Palm City Fl.(美国)进行细胞培养上清液光热测定。
结果。涤纶组光密度的最低平均值平为0.21(0.20-0.22)个光密度单位,对照组平均光密度最高,为0.36(0.35-0.38)个光密度单位;聚四氟乙烯组指标为0.35(0.33-0.36)。实验组比较,对照组与涤纶(p<0.001)、对照组与聚四氟乙烯(p=0.037)、涤纶与聚四氟乙烯(p<0.001)差异有统计学意义。与对照组相比,涤纶潜伏期导致细胞代谢活性下降41.7%(p<0.001)。暴露于聚四氟乙烯的细胞代谢活性与对照组接近,即符合内皮细胞体外培养的最佳条件。
结论。与聚对苯二甲酸乙二醇酯(涤纶)相比,聚四氟乙烯(PTFE)是体外内皮细胞代谢活动最不明显的抑制剂。
