ON THE POSSIBILITY OF NONTHERMAL BIOLOGICAL EFFECTS OF PULSED ELECTROMAGNETIC RADIATION

LAWRENCE D. SHER, EDWARD KRESCH, HERMAN P. SCHWAN · 1970

The study examined two mechanisms for alternating electrical fields interacting with biological tissue: heat development and field-induced force effects. For continuous wave fields in physiologic media, heating above 1°C always occurs before any field-induced force effect can appear. Using pearl-chain formation as a model, the researchers demonstrated that pulsed fields offer no greater likelihood than CW fields of equal RMS strength for producing pearl-chain formation.

Studies on the Effect of Radio-Frequency Waves on Biological Macromolecules

Shiro Takashima · 1966

Researchers irradiated alcohol dehydrogenase at 200 volts peak-to-peak across frequencies from 1 to 60 Mc/s. Enzyme activity was measured by the rate of DPN reduction, while DNA structure was assessed by optical density at 260 mu and viscosity. Optical density and viscosity of irradiated DNA showed no significant difference from control samples. The ratio of the first-order rate constant for irradiated versus control alcohol dehydrogenase was nearly unity, indicating no change in activity.

Laser irradiation of mouse liver caused histologic disruption and mitochondrial staining loss, while Physarum polycephalum showed central coagulation and peripheral cytoplasmic gelation. Freezing and thawing mouse liver diminished all measured nuclear metabolic activities, with rapid thawing causing greater impairment than slow thawing.

Effect of Radio-Frequency Fields on the Electrophoretic Mobility of Some Colloids

David J. Wilkins, John H. Heller · 1963

Four sizes of polystyrene latex, starch grains, and gelatin-coated polystyrene showed a voltage-dependent, frequency-specific loss of negative surface charge when exposed to radio-frequency fields. Each particle size had a specific frequency at which maximum reduction in electrophoretic mobility occurred, for example 1.305 y-diam PSL at 13 000 Mc/sec and starch grains at 7.50 Mc/sec. The lost charge recovered linearly over hours, with larger particles taking longer, but a one-minute exposure to a different frequency restored the original charge. At high particle concentrations no mobility change occurred, yet diluting an already-exposed concentrated suspension caused its mobility to drop to the level it would have had if exposed while dilute.

The study presented two units for electro-physiological investigations of the excitability of neuro-muscular preparations (n. ischiadicus and n. gastrocnemius) during irradiation with microwaves in the 10 cm range. A polystyrene chamber measuring 130 by 45 millimeters held the preparation during irradiation. The system included a unit for dosing the power flux density of the microwaves.

A New Physical Method of creating Chromosomal Aberrations

John H. Heller, A. A. Teixeira-Pinto · 1959

Researchers used a pulsed radio-frequency source at 27 Mc./s. with pulses of 5 X 10-5 sec. and 80 to 180 pulses per second. Garlic root tips were exposed for 5 minutes between insulated electrodes with no temperature rise in the water. Observed chromosomal aberrations included linear shortening of chromosomes, pseudochiasmiata, amitotic division, bridging, and irregularities in the chromosomal envelope.
