Clinical and experimental study on Jiudaiqingyuan oral liquid in strengthening immunologic function of children with recurrent respiratory infection(RRI) / 中国免疫学杂志

ABSTRACT

Objective:To explore the effect of Jiudaiqingyuan oral liquid in strengthening immunologic function of children with RRI.Methods:100 children with RRI were randomly divided into two groupsthe routine treatment group(RTG) and the group treated with Jiudaiqingyuan oral liquid (JDG).Venous blood was drawn before and after treatment to detect T lymphocyte subsets(SP method),NK cell activity (MTT method),sIL 2R(ELISA method),IgG,IgA,IgM(transmission turbidimetric method).Results:CD3 +,CD4 +,CD4 +/CD8 +,NK cell activity and IgG,IgA of the children with RRI were notably lower and CD8 +、IgM、sIL 6R markly higher before treatment.These indexes recovered to some extent after routine treatment but were still significantly different from those of normal controls(P0 05).Conclusion:Jiudaiqingyuan oral liquid has strong effect on immunologic regulation.It may markly enhance cellular and humoral function of children with RRI.
