摘要

<正>The brain of the Kun-Ming strain mice were irradiated with 0. 05 Gy of 12C6+ ion or 60Coγ-ray as the pre-exposure dose, and then irradiated with 2 Gy of 12C6+ ion or 60Coγ-ray as challenging irradiation dose at 4 h after per-exposure. Body weight and serum growth hormone (GH) concentration were measured at 35th day after irradiation. The results showed that irradiation of mouse brain with 2 Gy of I2CG+ ion or 60Coγ-ray significantly diminished mouse body weight and level of serum GH. The relative biological ef-
