摘要: 目的:观察绵马贯众水、乙醇两种提取物的抗病毒作用。方法:(1)离体实验:采用致细胞病变法观察绵马贯众水、乙醇两种提取物对流感病毒(FM1株)、呼吸道合胞病毒(Long)、副流感病毒(Ⅰ型、Ⅲ型)、腺病毒(AD3)的抑制作用,计算药物半数有效浓度(EC50)、治疗指数(TI);(2)在体实验:绵马贯众提取物按25%、12.5%、6.25%原液的浓度设高、中、低3个剂量给药,并设立正常对照组和病毒对照组,观察绵马贯众水、乙醇两种提取物对滴鼻感染FM1株流感病毒的昆明种小鼠肺指数的影响。结果:绵马贯众水、乙醇两种提取物对流感病毒(FM1株)、呼吸道合胞病毒(Long)、副流感病毒(Ⅰ型、Ⅲ型)、腺病毒(AD3)均具有一定的抗病毒作用,绵马贯众水提取物对上述病毒的EC50分别为110.58、141.72、126.21、152.66、182.55 ng/L;TI分别为34.94,14.21,30.62,25.31,21.17。绵马贯众乙醇提取物对上述病毒的EC50分别为152.08、168.27、132.28、135.26、156.38 ng/L;TI分别为14.24,11.12,16.37,16.01,13.84。绵马贯众水提物高、中剂量组、乙醇提取物高剂量组降低感染FM1株的小鼠肺指数,与病毒对照组比较差异有统计学意义(P<0.05,0.01)。结论:绵马贯众水、乙醇两种提取物均具有一定的抗病毒作用,可减低病毒引起的肺损伤。

Abstract: Objective:〖WT5”BZ〗To investigate the antiviral effects of the water and alcohol extracts of Dryopteris Crassirhizoma.〖WT5”HZ〗Methods:〖WT5”BZ〗(1)The cytopathic method was used to observe the antiviral effects in vitro of the water and alcohol extracts of Dryopteris Crassirhizoma on influenza virus(FM1),respiratory syncyntial virus(Long),para influenza virus(Ⅰ,Ⅲ),adenovirus(AD3);(2)Mice were randomly divided into treated group(25%,12.5%,6.25% extract as high,middle and low dose respectively),normal control group and model group,the in vivo antiviral effects of them were studied in mice infected with influenza virus(FM1) on induced lung index.〖WT5”HZ〗Results:〖WT5”BZ〗〖JP2〗Both the water and alcohol extracts of Dryopteris Crassirhizoma had the antiviral effect on influenza virus(FM1),respiratory syncyntial virus(Long),para influenza virus(Ⅰ,Ⅲ),adenovirus(AD3).EC50 of the water extract was 110.58,141.72,126.21,152.66 and 182.55 ng/L,TI was 34.94,14.21,30.62,25.31 and 21.17.〖JP〗EC50 of the alcohol extract was 152.08,168.27,132.28,135.26 and 156.38 ng/L,TI was 14.24,11.12,16.37,16.01 and 13.84.The water extract 250 mg/L(P<0.01)125 mg/L(P<0.05),the alcohol extract 250 mg/L(P<0.01)Significantly inhibited lung index of mice infected with influenza virus(FM1) increased the injury caused by virus.〖WT5”HZ〗Conclusions:〖WT5”BZ〗The water and alcohol extracts of Dryopteris Crassirhizoma have the antiviral effect,which can reduce the lung injury caused by virus.
