title: Effects of electromagnetic field (1.8/0.9 GHz) exposure on growth plate in growing rats.
abstract: The purpose of this study was to determine the effects of whole-body electromagnetic field (EMF) exposure on growth plates in growing male rats. Two groups of rats were exposed to either 900 MHz EMF or 1800 MHz EMF 2 h/day for 90 days. Sham control rats were kept under similar conditions without exposure to the EMF. The rats in the EMF group experienced a more rapid weight gain and increase in length (p < 0.05). Calcium, growth hormone, estradiol and testosterone levels in the EMF groups were higher (p < 0.05). The Safranin O staining density of femoral growth plate was lowest in the reserve zone of rats exposed to 1800 MHz and was increased in the proliferative zone of the control group (p < 0.05). The trabecular zone was thinnest among all zones and the reserve and proliferative zones were thicker (p < 0.05) than other zones in 1800 MHz group.In conclusion, 1800 MHz and 900 MHz EMF may cause prolong the growth phase in growing rats.
