目的观察玉叶解毒颗粒对多种呼吸道病毒导致病变的抑制作用。方法分别接种甲1型流感病毒FM1株、呼吸道合胞病毒long株、腺病毒7型、鼻病毒R14型于MDCK、A549、HEL细胞,采用细胞病变抑制法(CPE),观察玉叶解毒颗粒体外对多种呼吸道病毒作用。结果玉叶解毒颗粒在125mg/ml的浓度能完全抑制流感病毒A型FM1株,在6.25mg/ml浓度能完全抑制鼻病毒、腺病毒所致病变,在3.12mg/ml浓度下能完全抑制呼吸道合胞病毒。结论玉叶解毒颗粒具有体外抑制多种呼吸道病毒作用。
Objective To observe the inhibitory effect of Jade Leaf Detoxification Granules on the pathological changes caused by various respiratory viruses. Methods The FM1 strain of influenza A virus, the long strain of respiratory syncytial virus, the adenovirus type 7 and the rhinovirus type R14 were respectively inoculated into MDCK, A549 and HEL cells. The cytopathic effect (CPE) A variety of respiratory virus effect. Results Yuyoujiedu granule could completely inhibit the influenza A FM1 strain at a concentration of 125mg / ml, and could completely inhibit the rhinovirus and adenovirus-induced pathological changes at the concentration of 6.25mg / ml, and completely inhibited the respiratory tract at a concentration of 3.12mg / ml Syncytial virus. Conclusion Jade Leaf Detoxification granules can inhibit a variety of respiratory virus in vitro.
