Objective: To investigate the effect of Yiye Anti-influenza capsule (YYAFC) on the resistance to influenza A/H1N1 virus. Method: ICR mice were randomly divided into control group (0.5%CMC
20 mL·kg-1)
ribavirin(0.07 g·kg-1)
influenza virus particles group (4.24 g·kg-1) and YYAFC group(1.5
0.75
0.38 g·kg-1). The pneumonic model of mice were infected by influenza A(H1N1) with nasal drops
mice were administrated after infection virus in treatment andprecautiongroups. The lung index
death rate
death protection rate
the average survival period and life prolongation were calculated;cytopathic effect(CPE) was used to evaluate the anti-influenza virus(H1N1) effect of YYAFC in vitro. Result: Compared to normal group
mice were infected with the A/H1N1 influenza virus (FM1 and PR8)
the lung indexin treatment and precaution groupswassignificantly increased (P<0.01)
death rate was 90% and 90% in treatment group and 85%and 55% in precautiongroup
respectively
the average survival period was 9.20 days and 9.25 days in treatment griups and 9.35 days and 11.60 days in precaution group. In the treatment group of high and medium dosage YYAFC
the lung index decreased significantly
while the life span of mice was prolonged.In the precaution group of high and medium dosage YYAFC
the life span of mice was prolongedsignificantly. The IC50 of the sample inhibiting CPE caused by FM1 in vitro with doses of 0.89 g·L-1 and the TI was 6.75. Conclusion: YYAFC showed inhibitory effect on influenza A virus FM1 stain in vivo and in vitro.
