Each value represents mean ± S.E. Significant difference between groups in total WBCS count and differential leukocytic counts was analyzed by t-test in weeks 2 and 3, and one-way ANOVA in weeks 4 and 5 at p ≤ 0.05.

Parameters in the same column followed by different superscript letters are significantly different (p ≤ 0.05).
