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.

Versuche über den Einfluß elektromagnetischer Wellen auf die Reaktionsfähigkeit von Zellen und Geweben III. Mitteilung: Einfluß der Bestrahlung mit Rotlicht und Mikrowellen auf die Pinocytose von FL-Zellkulturen

Silke Heller · 1972

FL cells grown in tubes on plastic foil were inoculated with ink that had been irradiated with infrared and/or microwaves, then some cells were irradiated themselves, and uptake of ink particles was recorded. Irradiation of the ink with red light followed by irradiation of the cells with cm-waves yielded the highest number of cells that had taken up ink, and this difference from the non-irradiated group was statistically significant. The results indicated a maximum value for the uptake of ink particles into the cells.

Nonionizing Electromagnetic Wave Effects in Biological Materials and Systems

Curtis C. Johnson, Arthur W. Guy · 1972

The paper summarizes related work in the literature and presents new results. High radiation intensities can produce burns, cataracts, and chemical changes. Biological effects have been reported at lower intensities, but it is not known if they are harmful. Most effects are not harmful under controlled conditions and can be used for therapeutic purposes and diagnostic measurements.

The Influence of Electric Current on Bone Regeneration In Vivo

L. S. Lavine, I. Lustrin, M. H. Shamos, M. L. Moss · 1971

Ninety-one rabbits received a femoral defect and were exposed to 2-4 microamperes of direct current for one to three weeks. Three weeks of current at 2.5-3.5 microamperes produced the most new bone formation. Direct current increased healing by roughly a factor of two compared to controls without current. Three-week experimental animals showed similar bone formation to six-week controls.

RADIATION (Lasers, Microwaves, Electrical Fields)

DE ROUNDS, T LANWILL · 1971

The study aimed to determine if subthreshold laser energy in the green to infrared spectrum could produce chromosomal or genetic changes persisting through several cell generations. Human lung and tumor cells received UV laser irradiation as a single pulse. Tumor cells were more susceptible to damage than human fibroblasts, with dilatation and fragmentation of ribosomes in non-tumor cells and no detectable mitochondrial changes. Tumor cells showed extensive blebbing of cytoplasmic components, structureless and swollen mitochondria, and non-membrane bound clear areas of cytoplasm. Few cells showed dramatic changes in nuclear ultrastructure, suggesting the primary damage sites were not the protein synthesis machinery.

Microwave Absorption in a Helical Polypeptide Molecule

Mansel Davies, P. Maurel, A. H. Price · 1971

Researchers measured microwave absorption at 3, 8.5, 36, and 72 GHz on three molecular weight samples of poly(γ-benzyl-L-glutamate) in two solvents. In each case a distinct, narrow absorption centered between 2 and 15 GHz was observed and was almost temperature independent. The absorption’s frequency, intensity, and contour are not inconsistent with a helical-spring vibration mode proposed to explain an abnormal polarizability increase.
