Oxidative stress in dyslipidemia

The effect of radiofrequency electromagnetic radiation (EMR) on the balance of oxidants/antioxidants is not well studied, but there is a growing evidence that oxidative stress is involved in atherosclerosis. The aim of the study was to assess the effect of radiofrequency EMR on the oxidative stress status and the level of serum lipids in broadcasting (BC) and TV station operators. 49 BC and 61 TV station operators and control group of 110 operators, matched by sex and age, were studied. The EMR was assessed and the time-weighted average (TWA) was calculated. The malondialdehyde (MDA), as an index of oxidative stress, was determined with spectrofluorimetric method and the lipid indices were assessed with enzyme tests. A highly significant effect of radiofrequency EMR on MDA and on lipid indices studied was found, the greatest on MDA, followed by low density lipoprotein cholesterol (LDL-C) and total cholesterol (TC). The MDA correlated with TWA. The multiple regression analysis showed that the MDA values were predicted by TC and TWA, and MDA and TWA participated in the regression equations of TC and LDL-C. Our data show that the radiofrequency EMR contributes to oxidative stress and dyslipidemia in BC and TV station operators.
