Study of the Cardiovascular Effects of Exposure to Electromagnetic Field
Life Science Journal (2011-07)Abstract: This study was conducted to throw light on electromagnetic radiofrequency (EMR) emitted from cell phones which was accused of causing a number of negative health effects in the form of influencing on the heart and circulatory system. 110 adult albino rats, of both sexes, weighing 180- 200 gms were used in the present study. Animals were allocated into two main groups: group I, including rats exposed to cell phone EMF for 4 weeks; and group II, including rats exposed to EMF for 8 weeks. Each group was further subdivided into four subgroups, a control group and three subgroups exposed to EMF for either 1h/day, 2hrs/day or 3hrs/day, exposure being carried out six days/ week, at fixed time of the day. All rats were subjected to measurement of the systolic blood pressure on the day prior to the day of sacrifice, ECG recording, assessment of cardiac weights, absolute& relative, and MDA level in cardiac tissue, as well as determination of plasma renin activity, plasma total antioxidant capacity and plasma calcium level. Specimens from the apex of the heart were subjected to histopathological examinations. …

On conclusion, long-term exposure to cell phone EMF increases the liability for hypertension reflected on the ECG and cardiac weights which is accompanied by histopathological changes in the myocardium. In addition, an interaction of EMF with biological functions was achieved in the form of increased PRA, decreased plasma total antioxidant capacity and hypocalcemia.
