title: Prophylactic effect of a Beta vulgaris extract on experimental influenza infection in mice.
abstract: An aqueous Beta vulgaris extract was repeatedly administered to mice by intranasal (i.n.) instillation, prior to i.n. inoculation of influenza virus A/PR/8/34 (H1N1). The extract conferred a partial protection against the experimental influenza infection: there was a significant decrease in the hemagglutination titers recorded in mouse lung homogenates, a decrease in mortality rate and an increase in the mean survival time as compared with the untreated, virus-inoculated controls.
