四季抗病毒合剂抗A16型柯萨奇病毒作用- 5.0共5页
- 目的 观察四季抗病毒合剂的抗A16型柯萨奇病毒(CoxA16)作用.方法 采用75倍半数(75TCID50)、50 TCID50 CoxA16感染Vero细胞模型,5日龄BALB/c乳鼠腹腔注射感染1×106 TCID50 CoxA16建立动物模型,分别检测四季抗病毒合剂对CoxA16感染Vero细胞损伤的量效、时效指标;观察不同剂量四季抗病毒合剂对病毒感染乳鼠死亡率、存活时间、体质量、临床症状评分等的影响.结果 ①四季抗病毒合剂对Vero细胞的半数抑制浓度为9.59 mg·mL-1;②32.3 g·kg-1单次和连续给予四季抗病毒合剂对5日龄BALB/c乳鼠无明显致毒作用;③四季抗病毒合剂对CoxA16病毒具有显著抑制作用.浓度>1.22 mg·mL-1四季抗病毒合剂能显著提高Vero细胞存活率,抑制75 TCID50和50 TCID50 CoxA16诱发Vero细胞病变;④四季抗病毒合剂可显著改善CoxA16病毒感染乳鼠的临床症状,当剂量>1.62 g·kg-1时,乳鼠存活率等指标与利巴韦林相当或略高,且临床评分优于利巴韦林.结论 四季抗病毒合剂可显著抑制CoxA16细胞增殖,明显降低CoxA16诱发乳鼠病毒性致死率,显著改善乳鼠感染病毒的临床症状评分.%Objective To verify the antiviral effects of Siji Kangbingdu mixture (SJKBDM) against coxsackievirus A16 (CoxA16).Methods Vero cells and 5-day-old suckling mice, injected with 75/50 and 1×106 TCID50 CoxA16, were used as evaluation models.The preventive influences of SJKBDM against CoxA16 in Vero cells were assessed in the models.The effects of SJKBDM on the mortality, survival time, change rate of body weight, and clinical symptom scores of suckling mice were observed.Results ①The half maximal inhibitory concentration of SJKBDM on Vero cells was 9.59 mg·mL-1.②Toxic effects were not observed from 32.3 g·kg-1 single dose or continuous intraperitoneal injectin of SJKBDM in suckling BALB/c mice.③The SJKBDM had significant inhibitory effect against CoxA16 virus.Doses higher than 1.22 mg·mL-1 could significantly improve the Vero cell survival rate, and the SJKBDM inhibition of 75/50 TCID50 CoxA16 induced pathological changes in Vero cells.④The SJKBDM significantly improved clinical symptoms of mice with CoxA16 viral infection, especially with crude drug doses of higher than 1.62 g·kg-1.The survival rate and other indicators were comparable or slightly higher compared with ribavirin, and the clinical score was higher than that of ribavirin.Conclusion The SJKBDM has significant inhibitory effect on CoxA16 cell proliferation, significantly decreases death rate, and improves clinical symptoms of mice infected with CoxA16 virus.
四季抗病毒合剂及其主成分抗肠道病毒71型的作用及机制研究- 5.0共7页
- 目的探讨四季抗病毒合剂(Siji Kangbingdu Mixture,SJM)及其主成分(principal component,PC:连翘酯苷A、连翘酯苷B、连翘苷、甘草苷、甘草酸、木犀草苷、绿原酸、1,3-二咖啡酰奎宁酸、3,5-二咖啡酰奎宁酸)抗肠道病毒71型(enterovirus 71,EV71)增殖和感染的作用及其作用机制。方法MTS法检测SJM、PC对非洲绿猴肾细胞(Vero)的毒性;基于EV71感染细胞模型检测SJM、PC抗损伤的效果;基于EV71感染乳鼠模型观察SJM、PC对其存活率、存活时间、临床症状评分的改善情况;检测乳鼠模型肌肉与血清中白细胞介素-6(interleukin 6,IL-6)、肿瘤坏死因子-α(tumor necrosis factor-α,TNF-α)、单核细胞趋化蛋白-1(monocyte chemoattractant protein-1,MCP-1)水平。结果(1)EV71对Vero细胞的半数组织培养感染剂量(TCID 50)为10-5.68·mL^(-1);(2)SJM、PC对Vero细胞的半数抑制质量浓度分别为11.83 mg·mL^(-1)(按生药量计)、20.67μg·mL-1(按连翘酯苷A计);(3)单次和连续给予SJM与PC对ICR乳鼠无明显致毒作用;(4)SJM与PC可显著抑制EV71的增殖,以提高被感染细胞的存活率;(5)SJM与PC可显著改善被感染乳鼠的存活率、临床症状等指标;(6)SJM与PC均可显著调节肌肉与血清中IL-6、TNF-α、MCP-1的水平。结论SJM与PC可显著抑制EV71的增殖,调节免疫炎症因子,PC可在一定程度上替代SJM,发挥治疗手足口病的重要作用。
