title: Trace elements in nasal polyps.
abstract: The aim of our study is to evaluate the status of selenium and zinc in nasal polyp tissues and to investigate the possible role of trace elements and antioxidants including superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) in nasal polyps. In this study, the antioxidant enzyme and trace element levels measured in polyp tissues of 37 patients were compared with the levels measured in conchal mucosa of 27 control cases. The antioxidant enzyme and trace element levels in tissues were measured with graphite and flame spectrophotometry methods using Shimatsu UV.1601 spectrophotometer and Perkin Elmer atomic spectrometer. The mean tissue zinc and selenium levels were, respectively, 2.55 μg/g and 30.03 pg/g in patient group, 4.37 μg/g and 44.95 pg/g in control group. The mean tissue SOD and GSH-Px levels were, respectively, 4.27 and 0.69 U/mg protein in patient group, 7.09 and 0.77 U/mg protein in control group. When the measured levels in patients and control cases were compared, there were statistically significant differences between zinc, selenium, and SOD levels (P = 0.001). There was no significant difference between GSH-Px levels (P = 0.465). In conclusion, it has been revealed that the levels of zinc, selenium, and SOD in nasal polyps were significantly lower, and it may be concluded that this may have a role in the development of nasal polyps.
