[ effect of extremely low frequency pulsed electromagnetic field on serum lipids in male rabbit with and without hypercholesterol diet]

ABSTRACT

Increasing blood lipids is one of the mortality factors in human communities. In this study the effects of extremely low frequency electromagnetic field [EMF] exposure on the lipid profile [total cholesterol, triglycerides, LDL and HDL] in 48 male rabbits with normal diet and hyper-cholesterol diet were investigated. This study was experimentally conducted on 48 New Zealand adult male rabbits. The rabbits in control groups, C1 [normal diet] and C3 [hyper-cholesterol diet], were not exposed to any electromagnetic field. Sham exposed groups male rabbits, containing C2 [normal diet] and C4 [hyper-cholesterol diet] were exposed to sham stimulated [without electromagnetic stimulation] for 5 days, 2 hours per day, and the rabbits in the treatment groups, including T1 [normal diet] and T2 [hyper-cholesterol diet], were treated with triangular form 10 Hz of electromagnetic field for 5 days, 2 hours per day. Immediately after the mentioned period, blood samples were obtained from ear vein, and levels of so-called factors were measured. Acquired data were compared with statistical method of One-Way ANOVA. In the exposed groups, the levels of Total cholesterol, Triglycerides, and LDL were significantly decreased compared with the control groups; and the amount of HDL was significantly mounted [p<0.05]. The results acquired indicate extremely low frequency triangular electromagnetic field can positively alter the levels of serum lipids both in rabbits with normal diet and rabbits with hyper lipid diet
