Figure 1.

Body weight and temperature of surviving ricin-intoxicated antitoxin-treated mice. Mice were intranasally intoxicated with 2LD₅₀ (7 µg/kg) ricin. Antitoxin was administered to indicated groups of mice at 24 h PE. Sham group was administered PBS instead of either ricin or antitoxin. (A) Body weight and (B) body temperature were monitored for 30 days following intoxication. Sham—black triangles (n = 8); ricin—blue circles (n = 7); ricin + antitoxin—red squares (n = 12–16).
