Possible Use of Microwaves in the Management of Lung Disease

Charles Susskind · 1973

The analysis focused on detecting excessive fluid accumulation in interstitial lung regions, not on identifying diseased lung tissue itself. Prior attempts to distinguish normal from abnormal cells by microwave methods at the University of Pennsylvania and in the USSR yielded negative results because electrical properties are not sufficiently different. The author noted that wavelength must be smaller than the area being mapped, so centimetric waves suit decimetric lung cavities.

THE USE OF MICROWAVE HEATING TO INACTIVATE CHOLINESTERASE IN THE RAT BRAIN PRIOR TO ANALYSIS FOR ACETYLCHOLINE

W. B. STAVINOHA, S. T. WEINTRAUB, A. T. MODAK · 1973

Uniform cholinesterase inactivation was achieved in rat brain within 4 s and in mouse brain within 2 s. In rats, whole-brain acetylcholine was 25-4 + 1-5 nmol/g after irradiation compared to 13:8 + 1-7 nmol/g after standard sacrifice. In mice, whole-brain acetylcholine was 25:5 + 2:6 nmol/g after irradiation compared to 13-7 + 1:7 nmol/g after standard sacrifice.

A SEMICLASSICAL THEORY FOR NERVE EXCITATION BY A LOW INTENSITY ELECTROMAGNETIC FIELD

Ronald J. Spiegel, William T. Jones · 1973

The paper introduces a semiclassical theory that treats the electromagnetic field classically and the membrane dipoles quantum mechanically using the density matrix approach. The model assumes a double-dipole layer membrane where nerve excitation occurs when enough outer dipoles flip orientation to reduce the potential barrier.

Further Studies in Magnetotropism

J. C. Schwarzacher, L. J. Audus · 1973

Researchers exposed roots of Lepidium sativum, coleoptiles of Avena sativa, and sporangiophores of Phycomyces blakesleeanus to an intense magnetic gradient while rotating them on a slow klinostat at 0-5 rpm. All three species showed a growth curvature away from the magnet gap, down the magnetic gradient toward lower flux density, after an initial lag period. The reciprocal of the reaction time was the best measure of response and correlated with magnetic field parameters: for Avena and Phycomyces with log dH/dx and log H·dH/dx, and for Lepidium with log H. Only Stage I sporangiophores of Phycomyces responded to the magnetic gradient, while later stages showed no consistent curvature.

The Distribution of Radiofrequency Current and Burns

Becker CM, Malhotra IV, Hedley-Whyte J · 1973

The average maximum radiofrequency current in the electrocardioscope ground electrode was 175 milliamperes (range 20-290). Approximately 100 milliamperes per square centimeter for about 10 seconds can cause skin damage. The authors suggested that radiofrequency inductors (chokes) may prevent these burns.

Nonionizing Radiation Levels in the Washington, D.C., Area

Smith SW, Brown DG · 1973

The study monitored radiation from 20 Hz to 10 GHz at ten sites within a 25-mile radius of Washington, D.C., using a mobile van equipped with six broadband and six wideband receivers. Peak power densities were summed arithmetically over four biologically relevant frequency bands based on human body absorption percentages.

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.

MICROWAVE EFFECTS ON CENTRAL NERVOUS SYSTEM ATTRIBUTED TO THERMAL FACTORS

Eugene M. Taylor et al. · 1973

Non-radiation heating produced evoked potential changes comparable to microwave heating of the same magnitude. Both microwave and exchanger heating decreased latency only in late components of the evoked potential. Concurrent cooling during radiation reduced or reversed the latency changes, showing they track temperature direction and magnitude.
