| Popis: | The aim of this study was to detect the effect of a magnetic field on manganese transport into rat brains. An experimental group of Female Wistar rats was given 0.48 mg Mn2+ per kg body weight intratracheally twice a week for 3 months and simultaneously exposed to a magnetic field: B = 10 mT, f = 50 Hz for 1 hr. Rats in one control group of rats received the same dose of manganese as the experimental group but were not exposed to the magnetic field. Rats in a second control group had neither exposure to manganese nor exposure to the magnetic field. After the last dose, all rats were sacrificed and their brains and other tissues were analyzed for manganese content. The results indicated that the magnetic field had a positive effect on increasing the manganese content in the brains of rats in the experimental group relative to those of the control groups. Visual evoked potentials (VEP) measured at the end of the exposure periods on randomly selected experimental and control rats showed a shortened but not statistically significant latency of the P1 peak of VEP in rats that had been exposed to both factors but not in control rats. |
