摘要
采用放射免疫法测定３０例急性支气管肺炎患儿的唾液ＳＩｇＡ，结果：患儿组唾液ＳＩｇＡ明显低于对照组（７６．９±４２．９ｍｇ／Ｌ，３２０±３２．１ｍｇ／Ｌ，Ｐ＜０．０１），同时发现患儿唾液ＳＩｇＡ与血清ＩｇＡ之间呈正相关关系（ｒ＝０．９３，Ｐ＜０．０１）。提示急性支气管肺炎患儿大多有体液免疫紊乱，以ＳＩｇＡ及ＩｇＡ降低明显。
The saliva SigA in 30 cases of children with acute bronchopneumonia were detected by using RIA technique. The results showed that the level of saliva SIgA in studied children with acute bronchopneumonia (76.9±42.9mg/L) was significantly lower than normal control group(320±32.1mg/ L) with P<0.01. A linear correlation was simultaneously found between saliva SIgA and serum IgA (r=0. 93,P<0.01). The results suggest that the disorder of liquid immunity might exist in the children with acute bronchopneumonia.
