Effects of Whole-Body Magnetic Field on Changes of Glucose and Cortisol Hormone in Guinea Pigs‪.‬

Abstract: The main goal of this study was to evaluate the possible effect of whole-body magnetic field (MF) exposure on the variations of glucose and corlisol hormone levels on 36 adult male Guinea pigs. in four separate experiments, male Guinea pigs, were exposed to sinusoidal 5Hz ,0.013 [micro]T and 50 Hz - 0.207 [micro]T MF. Duration of exposure was 2 and 4 h/day over a period of 5 days. At the end of the exposure, blood samples were isolated and level of Serum glucose measured by Auto analyzer. cortisol content of blood sera was assayed by radioimmunoassay (RIA).We found significant decreases in the levels of glucose and cortisol hormone in 50 Hz - 0.207[micro]T MF after 2 h exposure (p 0.05). This condition was seen only for Glucose hormone after 4 h exposure (p 0.05). In all test samples , exposure after 2 or 4 h in 50 Hz - 0.207[micro]T, showed greater decrease compared to 5Hz ,0.013 [micro]T MF exposure. Our results indicated that a presumably direct effect of whole - body MF exposure on levels of glucose and cortisol hormones. Key words: Magnetic fields, glucose, cortisol, hormone, guinea pigs
