Figure 4
Effect of maoto extract on the proliferation of influenza virus in the nasal and bronchoalveolar cavities of upper respiratory tract influenza virus-infected mice. A/J mice were infected intranasally with mouse-adapted influenza virus A/PR/8/34 and administered orally with water or maoto extract from 4 to 52 hours postinfection. The infectious virus titers in nasal wash (a) and BALF (b) were estimated at 52 hours postinfection with plaque assay. Values represent mean ± S.E. (–18).
