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.

Stimulation of Partial Limb Regeneration in Rats

R. O. Becker · 1972

Control animals with no device or very low current showed minimal growth, while high current caused bone destruction. The experimental device produced a current of 3-6 nA. Rats receiving this current frequently developed organized regrowth of the distal humerus with epiphyseal centers. In animals with higher growth scores, new organized skeletal muscle formed distal to the amputation line along with ingrowth of nerves and blood vessels, and the authors concluded that appropriate electrical stimulation can restore regenerative growth in mammals.

DOSIMETRY STUDIES ON A UHF CAVITY EXPOSURE CHAMBER FOR RODENTS

Arthur W. Guy, Susan F. Korbel · 1972

Absorbed power density patterns were measured by thermographic techniques in simple phantom models of 227 gm rodents exposed to 500 MHz EM energy in a cavity type exposure chamber. The peak measured values varied between 0.35 and 90 mW /em? when the models were placed in fields corresponding to 1 mW/em= or lower of indicated power density. Peak absorption was highly dependent on posture and position of the phantom and was found to be as high as three orders of magnitude greater than that calculated for flat layered or equivalent spherical tissue models exposed to an incident plane wave with the same indicated power density.

Deformity and Intra-Uterine death after short wave therapy

Dietzel F, Kern W, Steckenmesser R · 1972

Researchers exposed 749 pregnant rats to a single abdominal short-wave treatment during the first 16 days of pregnancy, raising rectal temperatures to about 40° within 10 minutes. Treatment on the first two days of pregnancy caused 65% embryo deaths compared to 25% in controls. Embryonic injuries occurred only when maternal rectal temperature reached at least 40° for 10 minutes; lower temperatures caused no injuries.

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.
