In fiscal year 2011, using carbon, silicon, neon, and iron HI and X-rays, we demonstrated that 1) in the in utero studies, the priming low dose neon-ion irradiations could not induce any protective effects against the detrimental effects from the challenging irradiations from X-rays; 2) in the in vivo studies, no AR was observable in the following combinations for the priming and challenging irradiations: silicon plus carbon, iron plus carbon, and iron plus silicon. Thus we have finished all the radiation combinations in the in utero studies. The findings in the in utero studies indicate that induction of AR by X-rays against high LET HI is an event depending on the LET or/and species of the ions, and it seems hardly to induce AR by high LET HI against X-rays. For the in vivo studies, most radiation combinations are finished or under investigation, and we expect to complete the remaining combination in the fiscal year 2012., 平成23年度HIMAC共同利用研究成果発表会}, title = {胎児・成体マウスにおける放射線誘発適応応答は重粒子線にも当て嵌まるか}, year = {2012} }
