Serum selenium level in healthy Koreans.
Of trace elements in the serum of living organisms, selenium (Se) is an essential mineral and plays the role of an antioxidant as selenoproteins protecting the organism against oxidative damage induced by hydrogen peroxide, other lipid hydroperoxides, and their derivatives. The aim of this study was to determine the mean serum Se levels in healthy Korean volunteers (50 males and 50 females) by using an inductively coupled plasma-mass spectrometry method. The samples were collected at the Health Promotion Centre of Kangnam St. Mary's Hospital, College of Medicine, the Catholic University of Korea, Kangnam District, Seoul in accordance with procedures approved by the Institutional Review Board of the Catholic University of Korea. The mean serum Se level in healthy subjects was 112.05 +/- 30.42 microg/l. For gender, it was 120.81 +/- 27.37 microg/l for females and 103.29 +/- 31.05 microg/l for males. From the study result, there was a significant difference between the mean Se concentrations of gender groups (p = 0.0035). Also, the study indicated no effect of age on Se levels (p > 0.05) in the healthy individuals.
