    Author: Li X, Huang A.
    Journal: Zhonghua Er Bi Yan Hou Ke Za Zhi; 2000 Aug; 35(4):255-6. PubMed ID: 12768698.
    Abstract:
    OBJECTIVE: To investigate the distribution and content of immunoreaction interleukin-8(IL-8) antigen in the human nasal polyps. METHODS: Twenty-two cases of nasal polyp and 10 cases of normal inferior turbinate were studied with immunohistochemical SABC method and ELISA method. RESULTS: Immunohistochemical results demonstrated that IL-8 antigen staining occurred predominantly within inflammatory and epithelium cell plasm. The level of IL-8 in nasal polyp tissue was higher than in normal control specimens. The value in nasal polyp tissue was in 322.06-2091.41 pg/ml, but in normal with a range of 29.31-332.19 pg/ml. The results demonstrated a remarkable difference between the two groups (P < 0.001). CONCLUSION: These data demonstrated the presence of IL-8 antigen in nasal polyps. Thus IL-8 likely plays a significant role in the pathogenesis of this disease process. There is an important significance of finding a potential treatment method.
