Abstract Objective To observe the effects of radiosensitivity in cold-adaptation.Methods Male Wastar rats were exposed to 4 Gy 60Co γ-ray irradiation after cold-adaptation for 4 weeks at (4±2)℃.The change of nitric oxide (NO), adrenalin (ADR) and noradrenalin (NAD) in blood were observed.Results The results showed that treatment with cold-adaptation could increase the level of NO by irradiation, and attenuat the production of the ADR level in blood.Conclusion It is suggested that the cold-adaptation should attenuate the effect of stress response exposed to irradiation.
