Abstract:
Objective To detect levels of IL - 4 and INF - ? in induced sputum dynamically in children with mycnplasma pneamo-niae pneumonia( MPP), and to analyze the function of Th1 /Th2 cell factor immune response in the genesis and development of MPP, so as to evaluate the clinical value of induced sputum method in MPP research. Methods There were 38 cases who were diagnoses as MPP using 3% high osmotic pressure of saline water to ultrasonic atomizing inhalation for inducing sputum. ELISA was used to detect IL-4 and INF-?. Results The content of IL-4 in acute stage was higher than that in convalescence stage in induced sputum of MPP children. Severe stage was higher than mild stage. However, the comparison between acute and convalescence stage didn't have statistics difference in the content of INF-?, neither did the comparison between severe and mild stage. IL- 4/INF- ? in acute stage was higher than that in convalescence stage. Severe stage was higher than mild stage. In convalescence stage, the comparison of INF - ?, IL - 4, IL - 4/INF - ? between the severe and the mild didn' t have statistic significance. Conclusions IL-4 and INF - ? have participated in the monogenesis of MPP. The disequilibria of Th1 /Fh2 is existed in MPP and Th2 reaction predominates. So induced sputum analysis can be a better way to judge the light or heavy press degree of MPP practically, conveniently and sensitively.
