局部免疫系统是一种复杂的防御机构,它是保证机体免受各种抗原损害的第一个免疫屏障.从口腔开始的消化道各个部分都具有防卫功能,这已引起了许多研究者的兴趣,并证明了免疫在胃肠道发病机制中的作用.生物体液中免疫球蛋白的水平是局部免疫的重要指标之一,分泌的免疫球蛋白在保证器官粘膜功能的完整性中起着主导作用.本文对316例健康儿(新生儿26例,1～12月70例,1～12岁220例)的唾液、十
The local immune system is a complex defensive mechanism that is the first immune barrier that protects the body from damage by various antigens and has been of interest to many researchers since all parts of the digestive tract that start with the oral cavity have a defensive function , And demonstrated the role of immunity in the pathogenesis of the gastrointestinal tract.The level of immunoglobulins in biological fluids is one of the important indicators of local immunity and the secreted immunoglobulins play a leading role in ensuring the integrity of organ mucosal function In this paper, 316 cases of healthy children (26 newborns, 70 cases of 1 to 12 months, 220 cases of 1 to 12 years of saliva, ten
