Effects of 2100 MHz radio frequency radiation on the viscosity of blood and oxidative stress parameters in hypertensive and normal rats

Background: with the development of technology, human beings are increasinglyunder the exposure of radio frequency radiation (rfr) (due to wirelesstechnologies, mobile phones, base stations etc). the aim was to investigate thepossible effects of radio frequency radiation (rfr) on blood, aorta and heart tissuein hypertensive and non-hypertensive rats with various parameters. materials andmethods: male wistar albino rats were divided into 4 groups: 1.control (c),2.hypertension (h), 3.rfr, 4.rfr+hypertension (rfr+h). 60 mg/kg l-nitroargininemethyl ester (l-name) was administered for 1 month by oral gavage to inducehypertension. the rats were exposed to 2100 mhz rfr for 60 minutes/day, 5 days/week for 8 weeks. blood hematocrit, blood and plasma viscosity, malondialdehyde(mda), total nitric oxide (nox), and total sulphydril groups (rsh) / glutathione(gsh) levels in plasma and heart tissue were determined. histological examinationof the aortic wall and left ventricular muscle was performed. results: rfrexposure resulted in a marked increase in cardiac and plasma mda and noxlevels and a decrease in rsh/gsh levels (p<0.05). blood viscosity increased inthe hypertensive group with rfr exposure (p<0.05). there was an increase inleft ventricular weight and number of muscle cells in hypertensive groups(p<0.05). conclusion: according our study suggests that exposure to rfr causesmore negative effects on hypertension in terms of oxidative stress and antioxidantsin the heart and plasma. also, rfr exposure showed more prominent leftventricular fibrosis and aortic degenerative effects in hypertensive groups.
