title: [Peculiarities of carbohydrate energy and nitrogen metabolism in rat brain affected by magnetic fields of commercial frequency].
abstract: Carbohydrate oxidation, the coupling of oxidation with phosphorylation and the level of nucleic acids in the brain tissue were studied as affected by variable magnetic fields of commercial frequency (50 Hz) depending on intensity and regime of generation. A repeated effect (15-seances) of the 32 kA/m continuous magnetic field decreases the content of glycogen, creatine phosphate, intensity of oxygen uptake and etherification of inorganic phosphate, glutamine and increases the DNA content. The 7.5 kA/m continuous magnetic field has no effect on the studied metabolic indices in the brain whereas the interrupted field (1s impulse duration, 2s interimpulse interval) of the same intensity and exposition lowers the amount of glycogen, glucose, creatine phosphate, the RNA and DNA exposition lowers the amount of glycogen, glucose, creatine phosphate, the RNA and DNA levels, activates the oxidation processes, intensifies their coupling with phosphorylation.
