Evaluation of hematological toxicity in the control, 0.1 MBq, and 1 MBq groups. The mean counts of WBC, lymphocytes, PLT, and RBC, are expressed as mean ± SD (*: P < .05 between the control group and 1 MBq group. **: P < .05 between 0.1 MBq group and 1 MBq group by unpaired t-test with Bonferroni correction). The normal count of WBC (6.38 ± 1.80 *10^9/L), PLT (1241 ± 154 *10^9/L) and RBC (9.82 ± 0.5 *10^12/L) from the supplier are shown as dotted lines.
