中文摘要:

  采用健康雄性Ｗｉｓｔａｒ大鼠９７只，行胸部音 及分次，照射。于照射后０．５，１，２，３，６，１２个月分批活杀，进行病理形态观察。实验结果表明，照射后脊髓主要呈四种类型的变化：（１）出血型；（２）坏死型；（３）萎缩型：（４）空泡型。在光镜观察的基础上，对型病变的发生率做了统计，并对放射性脊髓损伤的发病机理进行了讨论。

英文摘要:

  The whole thorax of Wistar rat was irradiated with 60Co ray including single exposure (30Gy) and fractional exposures (30,60Gy).Animals from each group were sacrificed at 0.5,1,2,3,6,12months after irradiation.The sections of spinal cord were examined wit
