Perindopril improves neutrophil, platelet, and red blood cell recovery following lethal irradiation of grafted mice. B6D2F1 mice (n = 30) were irradiated with a single dose of 10 Gy and received 10⁶ bone marrow cells from perindopril-treated irradiated mice, irradiated mice, or untreated mice. Each data point represents the mean ± SD of 9 mice per experiments. The Kruskal-Wallis test was used to compare irradiated mice with perindopril-treated mice: lymphocytes (A; not significant [NS]; P = .08), neutrophils (B; P < .01), platelets (C; P < .001), and red blood cells (D; P < .03).
