在粘膜表面粘液中存在着很多分泌型免疫球蛋白(S-IgA),它对细菌和病毒有防御作用,在局部免疫上有重要意义。耳鼻咽喉器官是直接与外界异物相接触的部位,因此,在发生中耳炎、鼻窦炎和扁桃体炎时,S-IgA与此有很大关系。作者用免疫电泳方法测定健康成人和儿童的腮腺唾液S-IgA浓度与鼻分泌液中S-IgA浓度的关系,再测慢性中耳炎、慢性鼻窦炎、慢性扁桃体炎儿童的腮腺唾液S-IgA浓度,与正常者相比的结果如下:
There are many secretory immunoglobulins (S-IgA) in the mucosal mucus, which have a defensive effect on bacteria and viruses and are of great importance in local immunization. Otorhinolaryngology is a site that comes into direct contact with foreign bodies, so S-IgA is strongly associated with otitis media, sinusitis, and tonsillitis. The authors used immunoelectrophoresis to measure the concentration of salivary S-IgA in the parotid gland and the concentration of S-IgA in nasal secretions in healthy adults and children, and then measured the salivary S-IgA concentration in the parotid gland of children with chronic otitis media, chronic sinusitis, chronic tonsillitis, Compared with the normal results are as follows:
