Die bioklimatologische Bedeutung des elektrostatischen Gleichfeldes / The Bioclimatological Importance of the Constant Electrostatic Field

G. Fischer · 1973

Researchers exposed NMRI-Hahn mice to a constant electrostatic field of 24000 Volt/m, a Faraday cage, or normal lab conditions for 10 days and measured total activity, food intake, and water consumption. Total activity increased in the electrostatic field and decreased in the Faraday cage, with differences highly significant (p = < 0,001). Liver oxygen consumption was significantly higher in mice from the field chamber and lower in mice from the Faraday cage compared to controls. After 15 days exposure to fields of 40, 200, 1000, 5000, and 24000 V/m, plaque-forming cells in the spleen increased most at 1000–5000 V/m, while the Faraday cage reduced plaque counts below control levels. Rectal temperature rose from 37,5°C to 37,8°C in mice exposed to the field for 20 days.

Mathematics of Interaction Between Blood and Electromagnetic Fields

Abul Rashid · 1973

The author reviews electromagnetic energy effects on human systems and proposes blood-electromagnetic interaction as the basic mechanism for unexplained effects. Equations are also presented relating the change in velocity, density, pressure and temperature of blood when it is exposed to electromagnetic fields. The author notes that no attempt was made to solve the equations and that experimental validation is needed.

Accuracy of Cardiac Auscultation by Microwave

Raymond L. H. Murphy et al. · 1973

Fifty subjects, including twenty-seven patients with known heart murmurs and the remainder normal volunteers, were examined both directly and via a microwave telestethoscope by an observer 2.7 miles away who was blinded to their status. All murmurs of grade 2/6 or louder were accurately described, while two of the 32 grade 1/6 murmurs were not heard. Overall findings matched in 98 percent of cases, with 19 of 24 systolic murmurs graded identically and five differing by one grade.

Effects of active magnetic fields on permanently implanted triggered pacemakers

Nicholas P. D. Smyth et al. · 1973

Fifty-two patients with triggered ventricular, atrial, A-V synchronous, and A-V sequential pacemakers were exposed to magnetic fields generated by fixed and portable weapons detectors ranging from 100 Hz to 450 kHz at 0.5 to 1.35 gauss. No standard ventricular pacemaker, unipolar or bipolar, was affected by any of the weapons detectors. Of the eight patients with sensitive atrial pacemakers, one showed a single-beat rate increase that was not reproducible on repeat testing. In the two sensitive A-V groups, a brief rate change occurred in all three patients in each group, and any changes resolved immediately after leaving the magnetic field. No pacemaker stopped functioning, post-test ECGs showed no persistent rate changes, and no patient reported symptoms during exposure.

LOW-LEVEL MICROWAVE INTERACTION WITH ISOLATED MAMMALIAN HEARTS

R.G. Olson, C.H. Durney, J.L. Lords, C.C. Johnson · 1973

Researchers used isolated rat hearts back-perfused with oxygenated Ringer's solution and exposed them to microwave radiation in a stripline configuration inside a Faraday shield. Hearts were stabilized for 30 minutes then irradiated for 30 minutes at an absorbed power of 1.5 to 2.5 mW/cm³, which was determined using a liquid crystal optical fiber temperature probe. Exposure caused pronounced bradycardia, with heart rates decreasing 15 to 40 percent below baseline or temporary cessations of 5 to 12 seconds, and the effect reversed within 2 to 8 minutes during continued irradiation.

UHF IRRADIATION AND THE WORKER IN INDUSTRY

M. N. Sadchikov et al. · 1972

Researchers examined 59 workers with radiowave disease who were exposed to UHF electromagnetic fields up to several milliwatts per 1 em. Extracranial vessels showed a similar 48 percent reduction in hyperemia and a 57 percent increase in tone, while peripheral circulation in hands and feet remained within normal ranges. Rabbits irradiated at 50 microvolts per em2 for four hours daily over four months showed reduced phagocytic activity.
