[Expression and significance of Eotaxin and Eotaxin-2 in nasal polyposis and nasal polyp tissue].

OBJECTIVE

To study the expression of Eotaxin and Eotaxin-2 in nasal polyposis and nasal polyp and explore the different mechanism between polyposis and polyp.

METHOD: Fifteen cases of nasal polyposis, thirteen cases of polyp and eight cases of normal middle turbinate were studied with immunohistochemical SP method to detect the expression of Eotaxin and Eotaxin-2.

RESULT: There were significant differences between either two groups about the expression of Eotaxin-2 (P < 0.05). The expression of Eotaxin in nasal polyposis and polyp were dramatically higher than in controls (P < 0.05), the expression of Eotaxin between nasal polyposis and polyp was no remarkable difference (P > 0.05).

CONCLUSION

Both of Eotaxin and Eotaxin-2 likely play key roles in the inflammatory reaction process of nasal polyposis and polyp. The different expression of Eotaxin-2 between nasal polyposis and polyp demonstrates it may be one of the main causes in the different mechanism of the two diseases.
