Hematocrit and reticulocyte counts after PHZ treatment of normal and GATA-1^low animals.

(A) (B) Hematocrit (panel A) and reticulocyte counts (in percentage of total red cells) (panel B) in the blood of wild-type (closed circles) and GATA-1^low (open triangles) mice during recovery from anemia induced by PHZ (2 consecutive injections as indicated by the arrows). The day of the second PHZ injection was considered to be day 0. The results are presented as the mean ( ± SD) of the values observed in 18 wild-type and 12 GATA-1^low mice. Values are statistically different. *P < .05. §P < .01.
