Effect of radiophsophorus on hematology of mice during postnatal development.
Swiss albino mice at different stages of their postnatal development (one day, one week, two weeks, three weeks, four weeks age groups) were injected intraperitoneally with radioactive phosphorus (P-32) at the dose of 1.0 muCi/g body weight and studied for their hematological response at weekly intervals up to six weeks of age when they attain sexual maturity. In all the treated groups in both males and females, the radiation injury was evident after injection of radioactive phosphorus. Animals showed reduction in blood cell number and fall in hemoglobin and hematocrit levels after injection. Reparation was also evident in the animals after some lapse of time following P-32 administration. Morphological changes in different white blood cells were not observed. No radiation sickness symptoms were observed in any of the treated groups during the study. There was no radiation mortality. The radiation damage to blood forming organs was moderate. It was observed that the females showed a greater hematological damage than the males.
