Objective: In this study, an attempt was made to clarify theroles played by eosinophil cationoc protein (ECP) and soluble interleukin-2 receptor (sIL-2R) in the pathogenic mechanism of asthma.
Methods: The
fluorescent enzyme immunoassay (FEIA) and BA-ELISA were adopted to determine
ECP and sIL-2R in sera from 30 healthy subjects, 61 patients with advanced bronchial
asthma. ECP and sIL-2R in sera from 37 patients were determined continuously
after treatment.
Results: The
results showed that both the levels of ECP and sIL-2R in sera from the patients
with bronchial asthma in the acute stage were significantly higher than those
from the controls (P<0.01). Both the levels decreased significantly after
treatment (P<0.01).
Conclusion: ECP is an important inflammatory medium for airway inflammation, and the level of ECP in serum is conductive to the judgment for the activity and the severity Of asthmatic airway inflammation. The results indicated that a significant correlation exists between the activation of eosinophil and that of T-lymphocyte, as well as between the increased level of ECP and the activation of T-lymphocyte.
