ABSTRACT
Objective:
The aim of this study is to explore the expression of ECP in the neutrophils and its impact on the evaluation of nasal inflammation.Method:
Neutrophils and eosinophils in nasal secretions were collected and stained with ECP immunohistochemistry to observe the staining of ECP in different cells. The concentration of ECP and MPO in nasal secretion were detected of 32 patients with allergic rhinitis (AR group), 29 patients with chronic rhinosinusitis without nasal polyps and allergic rhinitis (CRSsNP group), and 21 healthy people (control group). The percentage of neutrophils and eosinophils were calculated and analyzed as well.Result:
ECP could be found in both eosinophils and neutrophils with immunohistochemical staining. The expression of ECP is much stronger in eosinophils than that in neutrophils. The ECP and MPO concentration in the nasal secretions of AR group and CRSsNP group were significantly higher than that in control group (P<0.000 1), and the ECP concentration in AR group and CRSsNP group had no difference. The expression of ECP in the AR group was not different from that in CRSsNP group, but the expression of MPO was significantly lower than that in CRSsNP group(P<0.000 1).Conclusion:
ECP is expressed in neutrophils, and which is likely to have influence on the objective evaluation to nasal inflammation. Combining with the expression of ECP and MPO, we can make a more accurate judgment of local inflammation.Palavras-chave
