摘要 目的观察疏清颗粒体外抗柯萨奇A16型(CoxA16)作用,为临床治疗由CoxA16感染引起的手足口病提供理论依据。方法观察由CoxA16感染人横纹肌肉瘤细胞后引起的细胞病变效应,并用MTT法检测疏清颗粒对CoxA16的抑制作用,同时以连花清瘟胶囊和板蓝根颗粒作为阳性对照药物。结果疏清颗粒能明显抑制CoxA16引起的细胞病变效应,疏清颗粒、连花清瘟胶囊和板蓝根颗粒抑制CoxA16增殖的半数有效浓度分别为0.080+0.008 mg/m1、0.072±0.044 mg/ml和0.141±0.035 mg/m1;选择指数分别为625.00+48.73、93.89+26.42、115.00+29.70。结论疏清颗粒与连花清瘟胶囊相比,细胞毒性较小,抑制CoxA16增殖作用差异无显著性;与板蓝根颗粒组相比,具有明显的抑制CoxA16增殖作用。
