We studied the impact of high-frequency electromagnetic field (HF EMF) on pancreas tissue, of sexually mature rats Wistar strain. Experimental animals were exposed to HF EMF, characteristics: frequency of 1,9 GHz, electric field strength: 4,79 V/m, magnetic field strength: 0,24 A/m and Specific absorption rate (SAR) value: 2,0 W/m2, 7 hours per day and 5 days per week, for thirty days. These are the same fields which are emitted by antennas for mobile communications and mobile phones. The experiment was conducted on total of 30 male rats divided into two groups: one group with 15 animals who were exposed to aforementioned fields and the other group with 15 individuals who weren’t exposed. Hematological analysis established a change of glucose and insulin concentration in blood, of exposed and control rats. Histological and stereological analysis established a change in volumetric density of exocrine and endocrine component of the pancreas and change in absolute surface of exocrine and endocrine cells in both groups were determined by unbiased design-based stereology. There was statistically a significant difference between the parameters in pancreas tissue exposed and control groups animals (ANOVA, F=7,15, p<0,05). Results of this research reached to significant statistical change in concentration gradient of insulin and glucose at animals who were exposed to HF EMF comparing to control group. Furthermore, histological measurements of stereological parameters show significant change at animals who were exposed to electromagnetic fields in contrary to control group. In conclusion our analysis shows pancreas’ sensitivity on impact of high-frequency electromagnetic fields.
