免疫是机体识别异物,排除异物,消灭异物的有力措施,以达到并保证机体自身稳定即维持免疫(生理)平衡。免疫过程中在某些情况下是有益于机体的,但有些情况是有害于机体,应该扬长避短使免疫反应为保护机体防治疾病服务。免疫反应是机体多脏器对抗原(异物)的反应,抗原集中主要作用于淋巴系统及其他血管内皮系统,也还作用于中枢神经的垂体,再作用于网状淋巴系统。免疫对内分泌及植物神经系统也都有一定的影响。激素在维护机体内部稳定上起着很重要的作用,也影响机体的免疫反应。象生长激素能促进抗体的产生,肾上腺皮质激素则有抑制细胞免疫及体液免疫的作用,对免疫反应是有明显影响的,临床上常被应用。实验证明,施行肾上腺切除后的动物和阿狄森氏病患者中淋巴细胞增多,而给以肾上腺 Immunization is a powerful measure for the body to identify foreign bodies, remove foreign bodies and eliminate foreign bodies in order to achieve and ensure that the body itself is stable, ie maintain the balance of immunity (physiology). In some cases during the immune process is beneficial to the body, but in some cases is harmful to the body, should avoid weaknesses so that the immune response to protect the body to prevent disease services. Immune response is the body’s multiple organs on the antigen (foreign body) reaction, antigen concentration mainly in the lymphatic system and other vascular endothelial system, also acts on the pituitary in the central nervous system, and then in the reticular lymphatic system. Immunity to endocrine and autonomic nervous system also have a certain impact. Hormones play an important role in maintaining the internal stability of the body, but also affect the body’s immune response. Like growth hormone can promote the production of antibodies, adrenal cortex hormones have inhibited the role of cellular and humoral immunity, the immune response is significantly affected, clinically used. Experiments show that, after the implementation of adrenalectomy in animals and Addison’s disease in patients with lymphocytes increased, while giving the adrenal gland
