(A) Survival rate. (B) Mice body weight. (C) Clinical score. Three-day-old
ICR mice are i.p. inoculated with EV71 and administrated with vehicle
(N = 10), lycorine (0.4 mpk, N =
10), 14 before EV71 infection (10 mpk, N = 10), 14 after EV71 infection (10 mpk, N = 9), and ribavirin (100 mpk, N = 11, or 50 mpk, N = 12).
