摘要
目的:研究菌毒清颗粒体外抗病毒的药效学。方法:将柯萨奇病毒B族3型(Cox B3)Nancy株、呼吸道合胞病毒(RSV)分别接种于人喉癌上皮Hep2细胞以复制细胞病毒模型。菌毒清颗粒原液(2 mg/ml)与氯原酸原液(2 mg/ml)以1∶2~1∶256倍比稀释后作用于病毒模型细胞,以Reed-Muench法计算50%细胞毒性浓度(TC50)和最大无毒浓度(TC0)。以1.25、0.625、0.312 5、0.15625 mg/ml菌毒清颗粒溶液与0.5、0.25、0.125、0.062 5 mg/ml绿原酸溶液培养病毒模型细胞,显微镜下评价细胞病变程度。以1.25、0.625、0.312 5、0.156 25、0.078 125 mg/ml菌毒清颗粒溶液与0.5、0.25、0.125、0.062 5、0.031 25 mg/ml绿原酸溶液作用于病毒模型细胞,Reed-Muench法计算对RSV、Cox B3细胞的50%抑制浓度(IC50)和治疗指数(TI)。结果:菌毒清颗粒TC50、TC0分别为1.79、1.25mg/ml,绿原酸TC50、TC0分别为0.71、0.5 mg/ml。当菌毒清颗粒溶液质量浓度为1.25 mg/ml时病毒感染细胞生长正常。菌毒清颗粒IC50均为0.22 mg/ml,TI均为8.14;绿原酸IC50分别为0.18、0.36 mg/ml,TI分别为3.94、1.97。结论:菌毒清颗粒具有体外抗Cox B3和RSV病毒的作用。
OBJECTIVE:To study in vitro antiviral effect of Junduqing granules.METHODS:Human laryngeal cancer Hep2 cells were inoculated with the Nancy strain of coxsackievirus B3(Cox B3) and respiratory syncytial virus(RSV) to establish virus-infected cell models.2 mg/ml original liquid of Junduqing granules and 2 mg/ml original liquid of chlorogenic acid which were diluted according to the ratio of 1 ∶ 2-1 ∶ 256 were used to act on the virus-infected cells.Reed-Muench method was adopted to calculate 50% toxic concentration(TC50)and maximal atoxic concentration(TC0).Virus-infected cells were cultured with solution of Junduqing granules of 1.25,0.625,0.312 5 and 0.156 25 mg/ml and chlorogenic acid solution 0.5,0.25,0.125,0.062 5 mg/ml,and then the degree of cytopathic effect was evaluated with a microscope.Virus-infected cells were cultured with 1.25,0.625,0.312 5,0.156 25,0.078 125 mg/ml solution of Junduqing granules and 0.5,0.25,0.125,0.062 5,0.031 25 mg/ml of chlorogenic acid solution,and Reed-Muench method was adopted to calculate 50% inhibitory concentration(IC50)and therapeutic index(TI)on RSV and Cox B3 cells.RESULTS:TC50of Junduqing granules was 1.79 mg/ml and TC0 was 1.25 mg/ml,TC50 of chlorogenic acid was 0.71 mg/ml and TC0 was 0.5 mg/ml.Virus-infected cells grew normally when the mass concentration of solution of Junduqing granules was 1.25 mg/ml.IC50 of Junduqing granules was 0.22 mg/ml and TI was 8.14;IC50of chlorogenic acid were 0.18 and0.36 mg/ml,TI were 3.94 and 1.97.CONCLUSIONS:Junduqing granules have in vitro anti-Cox B3 and RSV effect.
