Title: [Mitigation of mice radiation damage after acute and prolonged γ-irradiation by a laser device].

All mice died following acute γ-irradiation at the dose rate of 1.14 Gy/min for 5 days or combined exposure for 11 days. Thirty percent survival from prolonged exposure to the dose rate of 0.027 Gy/min was observed after 19-day γ- and 38-day combined irradiation. Peripheral blood parameters did not differ significantly after acute and prolonged exposure; however, hyperchromemia was observed in mice after 24 hours of acute γ-irradiation. The count of mitoses per 1000 nucleus-containing BM cells evidenced that BM was virtually collapsed after 72 hours since the acute γ-exposure. It was demonstrated that laser can manage protection from a broad range of ionizing radiation doses and mitigate the adverse effects of equally acute and prolonged radiation exposure.Read More
