Anti-influenza and anti-inflammatory effect of INAE in vitro. a Anti-influenza effect of INAE on MDCK cells. INAE was administrated 2 h prior to, simultaneously, or 2 h after influenza A virus infection to evaluate the antivirus capacity in phases of virus adhesion to cells, virus propagate in or release from the infected cells. b Effect of INAE on LPS induced nitric oxide (NO) production. LPS (1 μg/mL) was used as initiators in peritoneal macrophages and dexamethasone (10 μM) was used as positive control. Data were presented as mean ± S.D. (n = 4). *P < 0.05, ***P < 0.001 compared with LPS group, tested by ANOVA and Fisher’s PLSD
