MICROWAVE IRRADIATION SACRIFICE – APPLICATION IN NEUROCHEMICAL RESEARCH

D.E. Schmidt, M.J. Schmidt, G.A. Robison · 1973

Researchers applied microwave irradiation sacrifice to rats and measured brain temperature, enzyme inactivation rates, and levels of acetylcholine and cyclic AMP. Brain temperature reached 70-80°C within 15-20 seconds of microwave exposure. Complete and simultaneous inactivation of cholinesterase, phosphodiesterase, and adenyl cyclase occurred throughout the brain at temperatures of 60-75°C. Acetylcholine levels were higher than literature values, free choline was significantly lower at 28.7 nmoles/mg whole brain, and cyclic AMP levels were comparable to those from rapid freezing.

THE EFFECT OF MICROWAVES ON RATS SUBJECTED TO THE ACTION OF GASEOUS MEDIA WITH AN ALTERED CONTENT OF OXYGEN AND CHEMICAL AGENTS OF ANTIOXIDATIVE ACTION

V. M. Koldaev · 1972

Rats were subjected to microwave irradiation at a wavelength of 12.6 cm and frequency of 2380 Mc/s. Their resistance during inhalation of gaseous mixtures with reduced oxygen content and following introduction of some chemical agents was investigated. The duration of survival correlated with the extent of the muscle relaxant and chemical content. Chemical treatment at this level was accompanied with shortening and its increase with lengthening of the experimental period.

CHANGE IN METABOLISM OF NITROGENOUS SUBSTANCES IN ANIMAL NERVE TISSUE UNDER EFFECT OF ELECTROMAGNETIC FIELD OF SUPERHIGH FREQUENCY

L. I. Mishchenko, S. P. Frenkel · 1972

Researchers studied ammonia, glutamine, glutamate, amide nitrogen of proteins, AMP, and AMP desaminase activity in the brain of rats exposed to electric and magnetic fields of superhigh frequency. Electric field exposure increased ammonia, amide nitrogen in proteins, and AMP desaminase activity, which the authors suggest may be largely due to a decrease in ammonia and glutamine. Magnetic field exposure decreased ammonia and glutamine while increasing AMP and amide nitrogen in brain proteins.

PECULIARITIES OF NITROGEN METABOLISM IN THE RAT BRAIN UNDER EFFECT OF IMPULSIVE ELECTROMAGNETIC FIELD OF LOW FREQUENCY

F. A. Kolodub, H. I. Evtushenko · 1972

Researchers studied nitrogen metabolism in rat brain during exposure to a 7 kHz impulsive electromagnetic field at 24 and 72 kA/m. At 72 kA/m, ammonia and glutaminic acid content decreased while amide nitrogen of proteins was unchanged and adenylic acid desamination and glutamine synthesis were inhibited due to ATP deficit. At 24 kA/m with chronic exposure, ammonia shifts were phase-like and occurred without a corresponding rise in glutamine.
