近十多年来,由于免疫学的进展,关于扁桃体的生理功能及扁桃体摘除术的指征等,提出了一些新的问题,现综合部分文献如下,供参考。一、扁桃体的生理功能扁桃体虽无输入淋巴管,但公认其为一淋巴器官,具免疫功能。淋巴组织是人体免疫活动的基础,它分为中央型和周围型二类。前者直接来源于肠上皮或与肠上皮紧密结合的组织,主要的代表是胸腺。由第三、第四咽囊发育而来。在鸟类,胸腺和法氏囊(Bursa of Fabricius)共同负责免疫活动。胸腺产生小淋巴细胞,与抗原起反应,法氏囊负责产生抗体的浆细胞,在功能上两者虽有区别,但也有联系。鸡切除法氏囊,过一段时间胸腺皮质萎缩,脾变小,不仅影响抗体产
In recent ten years, due to the progress of immunology, the physiological function of tonsils and tonsillectomy indications, put forward some new problems, are integrated part of the following literature for reference. First, the physiological function of the tonsils Although there is no input of tonsils lymphatic vessels, but recognized as a lymphoid organs, with immune function. Lymphatic tissue is the basis of human immune activity, which is divided into two types of central and peripheral type. The former comes directly from the intestinal epithelium or tissue closely integrated with the intestinal epithelium, the main representative is the thymus. From the third and fourth pharyngeal pouch developed. In birds, thymus and Bursa of Fabricius jointly responsible for immune activity. Thymus produces small lymphocytes, react with antigen, the bursa is responsible for the production of antibody plasma cells, although there are differences in the function of both, but also linked. Chicken resection of the bursa, thymus cortical atrophy over time, the spleen becomes smaller, not only affect the antibody production
