Data represent means ± SE for n = 6 rats/group at 45 days of age and 5 rats/group at 180 days of age. Data are combined for male and female rats. WBC, white blood cells; RBC, red blood cells; HGB, hemoglobin; HCT, hematocrit; MCV, mean corpuscular volume; MCH, mean corpuscular hemoglobin; MCHC, mean corpuscular hemoglobin concentration; Polys, polymorphonuclear cells; Lymph, lymphocytes; Monos, monocytes. P values were determined by Student's t-test.
