[Variation in weight and food intake of rats exposed to a high-intensity electrical field at 50 Hz].
The effects of exposure to electric fields at 50 Hz of various intensities (100, 25, 10 kV/m) on the food intake and body growth were determined in the rat at various stages of development. The different field intensities were induced between 1.5 by 2 m steel plates. At 100 kV/m, 25 rats were exposed 8 h/d for 48 days. In respect to controls, after 2 weeks of exposure a marked decrease of the growth rate was observed in exposed animals, but not of the food intake. At 25 kV/m 11 animals, 28 days old, were exposed 8 h/d for 35 days. A slight decrease in growth rate, statistically significant only at the 23rd and the 26th day of exposure, was found. No effect was observed on food intake and full recovery of body weight of exposed animals was achieved in 4 weeks after the end of the exposure. At 10 kV/m, in addition to 5 rats 28 days old, exposed 8 h/d for 35 days and to the corresponding controls, 15 "sham exposed" animals were studied. No significant difference in growth rate was found between the exposed animals and the two other groups. Food intake of exposed was for two weeks of treatment the same of control animals. Thereafter, there was tendency toward a higher food intake in the exposed animals being significant during recovery.
