先天性非特异性免疫:是机体根据遗传或生理功能,对各种抗原本身,或其所含分子的反应性。是在种系发育过程中形成的。不是某一个体所特有,也不是针对某一特定抗原起作用。有如皮肤及粘膜的屏障作用、淋巴结及脾脏的过滤作用、单核—吞噬系统(即网状内皮系统)的吞噬作用以及某些体液因子(补体、溶菌酶、备解素、干扰素等)的作用等等。在第一次与抗原接触时即可起反应,在再次接触同种抗原时同样地起反应,而且反应强度不改变。获得性非特异性免疫:乃同样的免疫性,是由人工方法所获得的。对能产生这种作用的因
Congenital non-specific immunity: is the body according to genetic or physiological function, the various antigens themselves, or the reactivity of the contained molecules. Is formed in the development of germ line. Not unique to an individual or to a particular antigen. Such as barrier function of the skin and mucous membranes, filtration of lymph nodes and spleen, phagocytosis of the mononuclear-phagocytic system (ie, the reticuloendothelial system), and certain humoral factors (complement, lysozyme, properdin, interferon, etc.) Role and so on. In the first contact with the antigen can react, again in contact with alloantigen the same reaction, and the reaction intensity does not change. Acquired non-specific immunity: is the same immunity, is obtained by artificial methods. Cause of this effect
