Effects on blood cells following sublethal irradiation. Effects of perindopril on platelet (A), red blood cell (RBC) (B), and neutrophil (C) count following sublethal irradiation. B6D2F1 mice (n = 30) received a single dose of 7 Gy or 8.3 Gy plus either a placebo or 10, 30, or 90 mg/kg perindopril. Each data point represents the mean ± SD of 3 mice per experiment (n = 6). The Kruskal-Wallis test was used to compare irradiated and perindopril-treated mice. See Tables 2-3. RT indicates irradiation treated.
