从50年代开始,刘机体摄入放射性核素(内照射)期间的免疫反应性的改变作了深刻的研究。近年来,在免疫学方面取得了迅速进展,因此有必要用新的免疫学观点(特别是关于T和B免疫系统的概念)来解释这方面的文献资料。抗感染保护作用的非特异性因素在动物实验中,放射性核素进入机体后,皮肤粘膜的屏障作用、皮肤的杀菌特性及其自身菌丛均可发生改变。口腔和鼻咽腔粘膜的杀菌特性取决于唾液溶菌酶。对犬给以0.2~0.02μCi/kg剂量的~(90)锶,可见唾液中的溶菌酶活性随吸收量而改变:骨骼吸收量为4.5~100rad时,其活性增高,而吸收量为100~350rad时,其活性减低。
From the 1950s onwards, Liu body intake of radionuclides (internal irradiation) during the reactivity of the immunological changes made a profound study. In recent years, there has been rapid progress in immunology, and it is therefore necessary to explain the literature in this area with new immunological perspectives, particularly on the T and B immune systems. Non-specific factors of anti-infection protection In animal experiments, the radionuclide into the body, the barrier function of the skin and mucous membranes, the skin’s bactericidal properties and its own flora can be changed. Bactericidal properties of buccal and nasopharyngeal mucosa depend on salivary lysozyme. To the dog with 0.2 ~ 0.02μCi / kg dose of ~ (90) strontium, lysozyme activity in saliva with changes in the amount of absorption: When the bone absorption 4.5 ~ 100rad, its activity increased, and the absorption of 100 ~ At 350 rad its activity decreases.
