Induction of anemic rats by treatment with phenylhydrazine hydrochloride (PHZ) and the effects of ZnSO₄ on their RBC levels. (A) Normal rats were injected with saline or a single PHZ (60 mg/kg body weight) solution at day 0; (B) After two days, the PHZ-induced anemic rats were further injected with saline or different concentrations of ZnSO₄ solution. After another two days (at day 4), the rats were sacrificed, and RBC levels and other hematological indices were measured. *, significant difference between ZnSO₄-injected and saline-injected anemic rats (p < 0.05, n = 6). This figure is representative of three different experiments.
