摘　　要：以１５０Ｇｙ高能Ｘ射线１次或分２次（每次７５Ｇｙ，间隔２４ｈ）照射小鼠全脑，１周后处死小鼠，立即取出全脑称重（湿重）后测定。结果，１次与分２次照射，对脑组织靶区产生相同的放射生物学效应，即引起脑组织乳酸脱氢酶（ＬＤＨ）活性和Ｎａ＋、Ｃａ２＋含量明显升高（Ｐ＜０．０５或Ｐ＜０．０１），Ｋ＋含量下降（Ｐ＜０．０５）。Two groups of mice on whole brain were irradiated by 150 Gy X ray. One group was under single full dose and another group in twice fractionated irradiation. The results showed that the LDH, Na +, Ca 2+ of brain tissue increased significantly (P<0.05 or P<0.01) and the K + decreased significantly (P<0.05). No apparent differences were found between the 2 groups of mice.
