小鼠经亚致死剂量全身照射后的整个恢复过程可用分次照射的方法研究,以“骨髓”或“小肠”死亡作为标准。用12～16周龄的雄性和雌性 F_1(CBA×C57BL)小鼠。~(136)Cs 的γ线作全身照射,剂量率为45伦/分。第二次照射(有3～7次)是在第一次照射后1～30天的时间内进行,第一次不给防护剂照射350伦或500伦,在腹腔注射350毫克/公斤半胱胺-S-磷酸盐后照射595伦。
The whole recovery process of mice after sublethal dose of whole body irradiation can be studied by fractional irradiation, with “bone marrow” or “small intestine” death as the standard. Male and female F_1 (CBA × C57BL) mice at 12-16 weeks of age were used. ~ (136) Cs γ ray for whole body irradiation, the dose rate of 45 Lun / min. The second irradiation (3 to 7 times) is carried out within 1 to 30 days after the first irradiation. The first time, no 350 or 500 Lun cells are irradiated with the protective agent, and 350 mg / kg of cysteine Amine-S-phosphate 595 after Lun Lun.
