摘要: | 目的:观察清热解毒软胶囊(ADSC)体内抗甲型H1N1流感病毒作用,为其用于临床治疗甲型H1N1流感病毒感染提供实验依据。方法:将BALB/c小鼠随机分为正常对照组,模型对照组,阳性药物高、中、低剂量组[磷酸奥司他韦胶囊,0.04、0.02、0.01 g/(kg·d)]和ADSC高、中、低剂量组[1.5、0.75、0.375 g/(kg·d)]。除正常对照组外,其余各组小鼠均经鼻腔滴入滴度为1.6×10-5.2 的甲型 H1N1 流感病毒悬液复制染毒小鼠模型,造模6~8 h后ig相应药物,每天1次,连续5 d。给药结束后,观察7 d内小鼠体质量变化,计算15 d内小鼠的死亡率、死亡保护率及平均存活天数。另取小鼠,分组、给药同上,末次给药8 h后,测定小鼠肺指数和肺指数抑制率。结果:模型组小鼠体质量从第5天开始明显下降,第8天开始出现死亡(15 d内死亡率为85.7%),肺指数较正常对照组明显升高(P<0.01)。ADSC和磷酸奥司他韦胶囊均可减缓染毒小鼠体质量下降趋势,降低小鼠死亡率和肺指数,延长小鼠的平均存活天数。其中ADSC高剂量组和阳性药物高、中剂量组小鼠的平均存活天数显著高于模型对照组(P<0.05);除ADSC低剂量组外,其余各给药组小鼠的肺指数均显著低于模型对照组(P<0.05)。结论:ADSC对小鼠具有一定的体内抗甲型H1N1流感病毒的作用。 |
ABSTRACT: | OBJECTIVE: To observe the antiviral effects of Qingre jiedu soft capsule (ADSC) against influenza A H1N1 virus in vivo, and to provide a experimental support for clinical therapy of influenza A H1N1 virus. METHODS: BALB/c mice were randomly divided into normal control group,model control group, positive drug high-dose, medium-dose and low-dose groups [oseltamivir phosphate capsule, 0.04, 0.02, 0.01 g/(kg·d)] and ADSC high-dose, medium-dose and low-dose groups [1.5, 0.75, 0.375 g/(kg·d)].Except for normal control group, others groups were given influenza A H1N1 virus with titer 1.6×10-5.2 via nasal cavity to induce poisoned mice model; 6-8 h after modeling, they were given relevant medicine intragastrically, once a day, for 5 days. After medication, the change of body weight within 7 d were observed in mice; the mortality and death prevention rate within 15 d, mean survival days (MSDs) were calculated in mice.Other mice were selected and grouped, and they were given same drugs as above. 8 h after last medication, lung index and inhibition rate of lung index were determined in mice.RESULTS: In model control group, the body weight of mice decreased significantly since 5th day, and mice death was beginning to occur since 8th day (mortality of 85.7% within 15 d); the lung index was increased significantly compared to normal control group (P<0.01). Both ADSC and oseltamivir phosphate capsule could slow down the decrease of body weight in mice, decreased the mortality and lung index of mice, and prolonged MSDs; the MSDs of mice in ADSC high-dose,positive drug high-dose and medium-dose groups were significantly higher than model control group (P<0.05), and lung index was significantly lower than model control group except that of ADSC low-dose group (P<0.05). CONCLUSIONS: ADSC has certain antiviral effect against influenza A H1N1 virus in vivo. |
