Text

Introduction: It is to assume that cyclooxygenases play a decisive role in the pathogenesis of nasal polyposis.

Cyclooxygenases 1 (Cox-1) and 2 (Cox-2) are relevant in arachidonic acid metabolism and are therefore essential for the synthesis of prostaglandins.

However, it s still unknown in which extent a different expression of the cyclooxygenases has an impact on the responsible pathomachanism of polyposis nasi.

Methods: 87 tissue surgical specimens were immunohistochemically labeled for Cox-1 and Cox-2. These specimens were taken from patients with nasal obstruction without inflammatory disease during turbinate surgery and from patients suffering from chronic rhinosinusitis with polyposis. Staining intensities were semiquantitatively estimated and statistically analyzed.

Results: In nasal polyps the expression of Cox-1 was significantly higher than in specimens without inflammatory disease. On the other hand Cox 2 expression was labelled similarly in nasal polyps and in specimens without inflammatory disease.

Conclusion: These data show a dysbalance of Cox expression in nasal polyps. This dysbalance might play a key role in the pathogenesis of nasal polyposis.
