Effect of Microwaves on the Eye

Leo Birenbaum et al. · 1969

Researchers investigated the acute effects of continuous-wave and pulsed 5.5 GHz microwave radiation on rabbit eyes. They used a closed-waveguide system that delivered power directly to the eye, allowing precise measurement of power entering the eye. Lens opacities appeared within four days after sufficient exposure; three minutes at one watt exceeded the cataractogenic threshold, while two hours at 1/2-watt caused no acute effect. Threshold curves for continuous-wave and pulsed (0.001 duty cycle) radiation showed no substantial difference, indicating that average power determined injury.

Effects of Electroanesthesia on Synaptic Ultrastructure

ION AND WATER TRANSPORT ACROSS MULTICELLULAR MEMBRANES THROUGH EXTRACELLULAR SPACE BY CHEMIPERISTALTIC WAVES

Freeman W. Cope · 1969

The author develops an elementary theory of sodium transport across an idealized membrane by chemiperistaltic waves. The model assumes waves of configurational change in cell surface proteins that alter ion complexing preference and water structure. The theory is consistent with frog skin experiments showing only about 8 per cent of total sodium participates in transport and most sodium is complexed.

Inhibition of Bacterial Cell Growth by 136 gc Microwaves

S. J. Webb, D. D. Dodds · 1968

Researchers exposed Escherichia coli B to 136 gc microwaves at about 10 W for up to 4 hours. When cells were exposed immediately after washing, no cell divisions occurred but cell counts did not decrease. When cells were pre-incubated for 90 minutes before exposure, cell numbers approximately doubled before inhibition began.

Hypogonadism After Microwave Radiation

David S. Rosenthal, Steven G. Beering · 1968

Researchers reported a case of a 31-year-old man repeatedly exposed at close range to high-powered microwave emission over a four-year period. Testicular biopsy revealed tubular atrophy with focal necrosis and interstitial edema. Hypospermia continued for at least a year after the patient's last exposure.

STUDIES ON THE COMBINED EFFECT OF MICROWAVES AND SOME DRUGS ON BIOELECTRIC ACTIVITY OF THE RABBIT CENTRAL NERVOUS SYSTEM

Stanisław Barański, Zbigniew Edelwejn · 1968

Researchers used 65 male rabbits, exposing one group to a single 20-minute pulse-modulated 10 cm microwave at 20 mW/cm² and another group to chronic 3-hour daily sessions totaling 70–80 hours at 7 mW/cm². In single-exposure rabbits pretreated with phenactil, microwaves still produced EEG desynchronization; cardiazole triggered a threshold reaction at a lower dose, while strychnine evoked a weaker spike response than in controls. Chronic exposure produced persistent EEG desynchronization with high amplitude and reduced phenactil synchronization. Cardiazole caused violent convulsions at 3 mg/kg and strychnine produced spikes in most animals with two deaths.

Effect of Microwaves at X-Band on Guinea-pig Skin in Tissue Culture - 2. Effect of the Radiation on Skin Biochemistry

SHIRLEY A. CARNEY, J. C. LAWRENCE, C. R. RICKETTS · 1968

Researchers exposed small pieces of guinea-pig skin to a uniform field of X-band microwaves at 8,730 MHz. Measurements showed that 26% of the incident energy was reflected, 34.4 was absorbed, and the remaining 40% was transmitted. Exposure caused a graded reduction in phosphate uptake into phospholipid, nucleic acid, and phosphoprotein fractions, a graded reduction in sulphate uptake with increasing energy density, and a significant reduction in proline uptake into collagen at the three highest power densities.
