实验方法:用120只小鼠,分成四组,第一组用一次总剂量500r X綫照射,第二组把小鼠的下肢和驅体下部浸入95—100℃热水中燙1秒钟,第三组以上两因素同时作用,第四组作对照。在用以上方法照射引起損伤后的不同时期內,經皮下注射以Fe~(59)标記的氯化鉄生理溶液,经一天后杀死小鼠,分离血液中的血球,测定其放射性。 結果:損伤后小鼠紅血球中放射性鉄对健康小
Experimental method: 120 mice were divided into four groups, the first group was irradiated with a total dose of 500r X-rays, and the second group was immersed in the hot water of 95-100° C. for 1 second in the lower limbs and the lower part of the mice. The third group and the above two factors act simultaneously, and the fourth group serves as a comparison. In different periods after irradiation with the above method, the physiological solution of strontium chloride labeled with Fe~(59) was injected subcutaneously. After one day, the mice were sacrificed, and the blood cells in the blood were separated and their radioactivity was measured. Results: The radioactive cesium in the red blood cells of mice after injury was less healthy
