Abstract

Overview

The increasing prevalence of devices emitting electromagnetic radiation (EMR) in everyday settings has prompted significant research into potential adverse effects on living organisms. This in vitro study specifically investigates the impact of EMR from liquid-crystal-display (LCD) monitors on cellular structures and the protective role of vitamin A against such effects.

Objectives

  • Assess changes in malondialdehyde (MDA) concentration—a marker of lipid peroxidation—in blood platelets exposed to EMR.
  • Evaluate the antioxidant role of vitamin A during exposure.

Materials and Methods

EMR from LCD monitors, characterized by parameters such as 1 kHz frequency and 220 V/m intensity at 15 cm distance, was tested. Porcine blood platelets were exposed at intervals of 30 and 60 min, with subsets receiving vitamin A supplementation.

Findings

  • Significant increase in MDA concentration in blood platelets after 60 minutes of exposure compared to control.
  • Vitamin A addition led to a noticeable reduction in MDA levels.

Conclusion

These findings highlight the potentially harmful effects of EMR on cellular membranes, evidenced by altered MDA concentrations, while also suggesting that vitamin A may mitigate these risks.
