ABSTRACT
Objective To study the immune responses of Th1 and Th2 subsets of T cells in 26 children with mycoplasma pneumo-niae pneumonia(MPP).Methods ELISA was used to detect the levels of interferon- ?( IFN- ?) and interleukin-4(IL-4) in the serum in 12 healthy children as normal controls and 26 patients of acute stage as acute stage MPP group, 9 of whom in recovery stage were as recovery stage MPP group. Results IFN - ? level in acute stage MPP group was significant higher than that in normal controls (P 0.05); and IFN - 7/IL - 4 ratio was significant higher than that in normal controls( P0.05).Conclusion Thl responses increase and Th2 responses decrease in children with MPP,and this kind of response persists during the recovery stage.
ABSTRACT
Objective To explore the changes of interleukin-10(IL-10) and transforming growth factor-beta 1(TGF-?1)in 26 children with mycoplasma pneumoniae pneumonia(MPP).Methods Enzyme-linked immunosorbent assay(ELISA) was used to detect the levels of IL-10 and TGF-?1 in the serum of 12 healthy children as normal controls and 26 patients of acute stage as acute stage MPP group,9 of acute stage MPP group in recovery stage as recovery stage MPP group.The levels of IL-10 and TGF-?1 were compared between the three groups.Results IL-10 level in acute stage MPP group was significantly lower than that in normal controls(P
