Chemiluminescence of neutrophiles stimulated by opsonized Zymosan in children with asthma bronchiale and pneumonia

摘要

Oxygen metabolism of neutrophils after stimulation with opsonized zymosan was examined using Chemiluminescence test (in the presence of the patient serum or pooled serum). Into the study 37 children aged from 2 to 12 years were enrolled (20 girls and 17 boys). 10 healthy volunteers comprised the control group (group III). Two groups of patients were established: group I - children with bronchial asthma (without infection), group Ⅱ - children with pneumonia. The examination in both groups was performed twice - in acute phase and in remission period. The group I in acute phase comprised 16 children and in remission phase 9 children, group Ⅱ - 21 children in acute phase and 9 children in remission phase, respectively. The following parameters of CL were estimated average value of so called spontaneous CL, maximal excitation of neutrophils after stimulation by zymogen (CLmax), time of zymosan opsonization. The following results were obtained: increased spontaneous CL and CLmax (at the presence of both sera) in acute phase of bronchial asthma and pneumonia in comparision to the control group. In the period of remission both these parameters were insignificantly decreased. The longest time of zymosan opsonization in acute period of disease was observed in children with pneumonia (18 min.). This time did not change during remission phase. Only slightly longer time of opsonization was observed in the patients from group Ⅰ (in exacerbation) (15 min) than in the control group (13,1 min). This time was prolonged in the clinical remission (20 min).
