Acidic Hib[crude] administration does not have a therapeutic effect on PR8 virus infection. a PR8 virus inoculation scheme and therapy schedule is shown. b Changes in body weight after viral inoculation were evaluated in each mouse. n = 5 per group. c The survival percentage is shown. d Mice were euthanized, and the lungs were collected on days 3 and 5. The viral titer in 1 g of lung was evaluated. n = 5 per group. (b–d) Student’s t test (b, d), and Log-rank test (c) were performed to analyze statistical significance. n.s: not significant. The results represent three similar experiments
