Abstract: 本文报道了小剂量 X 射线分次全身照射和低剂量率60Coγ射线持续全身照射对雄性大鼠下丘脑组织中 LRH 含量,血清及尿中 LH 和睾丸酮含量影响的实验结果。接受 X 射线照射的大鼠,全身累积吸收剂量为1.5Gy 和3.0Gy,下丘脑组织中 LRH 含量均于停照后1周显著高于对照组;血清 LH含量在3.0Gy 组于停照后4周高于对照组;尿中睾丸酮含量1.5Gy 组在停照后2和4周及3.0Gy 组在停照后2周均显著高于对照组。接受60Coγ射线照射的大鼠,于照射结束后24小时血清 LH 含量在全身累积吸收剂量为1.76Gy 组显著低于对照组;血清中睾丸酮含量在1.37和1。76Gy 组、尿中睾丸酮含量在0.98Gy 组均显著高于相应对照组。
