“…(cm mm), there was nonevident variation between II & III (P = 0.107). This result agrees with that of Ashwini et al [20] and Gupta et al [18] who found that the absolute neutrophil count (×10 9 /L) was 0.69 ± 0.44 (median 0.62) in cases with AA but not determine its severity and that due to hypoplastic bone marrow and peripheral pancytopenia [21] . In the present study, as regard to reticulocyte count, There was a significant decrease between studied groups (p< 0.001), also there was a significant decrease between (II & III), (II & IV), (I & III), (I & IV) (p< 0.001) as compared to healthy controls where in group (I), it ranged between 0.1 -0.4 (%) with a mean of 0.263±0.106, in group (II),it ranged between 0.1 -0.4 (%) with a mean of 0.263±0.102, in group (III), it ranged between 0.3 -0.9 (%) with a mean of 0.667±0.225, in group (IV), it ranged between 0.6 -1.9 (%) with a mean of 1.130±0.467, there was non-evident variation between (II & I) and (III & IV) as P-value was (1.000 and 0.655) respectively, which is in agreement with the Mary et al [22] study.…”
