目的:对南板蓝根和北板蓝根进行抗甲型流感病毒作用的实验研究,了解广西习用品南板蓝根与北板蓝根抗甲型流感病毒作用的差异。方法:用鸡胚培养法观察两种板蓝根对甲型流感病毒的直接作用、治疗作用及预防作用,以利巴韦林为阳性对照药。结果:血凝滴度实验表明,南、北板蓝根均能明显灭活甲型流感病毒,其中直接作用与预防作用北板蓝根强于南板蓝根,治疗作用南板蓝根稍强。结论:南、北板蓝根都有抗甲型流感病毒作用。
OBJECTIVE: To study the anti-influenza A virus activity of southern and southern Radix Isatidis and find out the difference between the anti-influenza A and anti-influenza viruses of Southern Bananas and Radix Isatidis in Guangxi. Methods: The direct effect, therapeutic effect and preventive effect of two kinds of Banlangen on influenza A virus were observed by chicken embryo culture method. Ribavirin was used as positive control. Results: Hemagglutination titer experiments showed that both southern and northern Banlangen could inactivate influenza A virus significantly. The direct and preventive effect of Banlangen was stronger than that of Banlangen, and the therapeutic effect of Ban Ban Lan was slightly stronger. Conclusion: Both southern and northern Banlangen have anti-influenza A virus effect.
