长期以来,人们对免疫的认识,只是片面地看到在防御传染病方面的作用,而对机体因免疫功能失调所引起的许多免疫性疾病没有正确的认识。随着与免疫有关科学(如生物学、生理学、生物化学、病理学及临床医学)的发展,以及各种免疫学新技术(如免疫电镜、放射免疫、免疫化学及细胞培养等)的应用,对机体的特异性免疫与非特异性免疫、细胞免疫和体液免疫的本质及其相关联系作了进一步的研究,从而对免疫的本质有了进一步的认识。目前免疫的概念已远远超出了防御传染的狭义范畴。现已公认,免疫的概念是“自我识别”、“排除非己”和达到“自我稳定”的一种复杂的生理性保护功能。因此机
For a long time, people’s understanding of immunity has only seen the one-sided role in the prevention of infectious diseases, but not the correct understanding of many immune diseases caused by immune dysfunction. With the development of immunology-related science such as biology, physiology, biochemistry, pathology and clinical medicine, as well as the application of various new immunological technologies such as immunoelectron microscopy, radioimmunoassay, immunochemistry and cell culture, The body of the specific immune and non-specific immunity, cellular immunity and humoral immunity and its related nature of the further study, and thus have further understanding of the nature of the immune. The current concept of immunity goes far beyond the narrow category of defensive contagion. It is now recognized that the concept of immunity is a complex physiological protection function of “self-identification ”, “excluding non-self ” and “self-stability ”. So machine
