Abstract:

Young adult male albino rats received 50 rday of Co-60 gamma radiation for 91 days with results compared with non-irradiated controls. The latter surpassed the irradiated animals in increase in body weight skeletal growth rate of fracture healing and bone strength. A macrofractionated study was conducted with A one group of young adult male albino rats which received 50 rday of C -60 gamma radiation continuously for 77 days b one group with alterna ing 7-day radiation and rest periods for the sa e length of time and c one group receiving no radiation. The fractionated radiation produced less deleterious effects on certain aspects of skeletal statu than the continuous radiation exposure and the non-irradiated controls surpasse the two irradiated groups. Quantitative microradiographic techniques were applied to a study of the mechanism of the healing of bone fractures. Author
