Abstract:

Introduction: Selenium (Se) is an essential micronutrient to human health. The biological actions of selenium are mediated by several selenium-dependent enzymes, the best known of which are glutathione peroxidase, thioredoxin reductase, and the iodothyronine 5-monodeiodinase. Some epidemiological studies suggest low selenium levels might predispose an individual to an increased incidence of cardiovascular disorders, cancer, and cretinism in populations from areas with low environmental availability of selenium. Aim: The purpose of this study was to assess plasma selenium level and dietary Se intake of 60 healthy adults living in Tlemcen, west of Algeria. Selenium was measured using differential pulse cathodic stripping voltammetry. Data of Se intake were collected by weighed 3-day dietary records. Results: The mean (±SD) of plasma selenium concentrations was 68.13±16.43μg/L. This concentration did not vary significantly (P>0.05) in relation to the gender of the subject, with concentrations of 70.63±17.47μg/L in men and 66.51±15.34μg/L in women group. Individuals older than 60 years had a whole blood selenium concentration significantly lower than the rest of the population. The mean of Se dietary intake was 48.23±10.10 μg/day. The subjects were found to consume less Se than the U.S. Recommended Dietary Allowance values. Conclusion: The Se status among the subjects examined was marginally lower compared to values reported from other areas of the world.

Biography :

Dennouni-Medjati Nouria is Lecturer in Department of Biology at Tlemcen University. Her research interests are the essential trace elements particularly selenium. This micronutrient is a trace element associated with the activity of the antioxidant enzyme glutathione peroxidase. It is considered to be a protective agent against free radicals through enhanced enzyme activity. She has published in reputed journals.
