Effects of whole body chronic 50 Hz sinusoidal weak magnetic field exposure on the rat pituitary hormones

We have investigated whether functions of pituitary gland change when the rats are exposed to sinusoidal magnetic fields at dark. In this study, 26 Wistar Albino rats were divided into two groups as experimental (n=14) and sham group (n=12). Experimental was exposed to 0.75 mT sinusoidal magnetic field procuded by Helmholtz coils and sham group was housed between inactivated Helmholtz coils, for one month. After one month Animals were sacrificed and their blood were taken. Serum hormone levels were determined by Radioimmunassay method. In exposed group, serum cortisol TSH, FSH and prolactin concentration did not statistically changed according to sham exposed group (p>0.05), but Growth Hormone and testesterone levels statistically changed (p<0.05).
