Tuberculosis of the Larynx

G. McD. Van Poole · 1934

Researchers applied a shortwave condenser field at 3.96 m wavelength to agar blocks with a thermoindicator to visualize thermal zones. The thermoindicator changed at 37 degrees C. With equal plates on both sides the heated zone was band-shaped and matched the plate width; with unequal plates it formed a truncated cone following the plates' outer edges. Heating started near the plates and spread toward the center until zones merged. The author noted that wavelength relative to the maximal heating value affected heat distribution, with shorter wavelengths giving more even penetration.

THE EFFECT OF HYPERPYREXIA INDUCED BY RADIATION UPON THE LEUKOCYTE COUNT

William Bierman, M.D. · 1934

Researchers induced hyperpyrexia in 24 human subjects using 30 m radio waves, raising rectal temperature to 104° to 106° F. and maintaining it for 3 to 4 hours. White blood cells initially fell 25 to 30 per cent by the end of the first or second hour. By the third to fifth hour leukocyte counts rose to 80 per cent above baseline, reaching as high as 22,600, and immature forms such as myelocytes, metamyelocytes, premyelocytes, and myeloblasts appeared.

Ein räumliches Modell für die thermischen Wirkungen elektrischer Schwingungen in der Therapie

Holzer, W. · 1934

Holzer described a simple system using parallel insertion of a resistance and a condenser to model the thermal action of Hertzian short waves in electrotherapy. The model uses a diagram to show the special relationship between the diathermic zone and the short wave zone. This consideration explains the relatively intense heating of the skin in diathermy. It also explains the uniform heating in short-wave therapy. The principal difference between diathermy and short-wave therapy is the latter's property of negativity regarding resistance.

Referat uber elektrische Wellen und biologische Phanomen

Dessauer, F. · 1934

Ultra-short diathermic waves increased conductive capacity, permitting more homogeneous heat in deep tissues and avoiding metallic skin contact during treatment of inflammatory processes. Varying the wavelength could direct maximum heat to deep tissues, but this approach did not yield notable practical effects despite initial hopes. Microscopic effects in cells and organ elements such as blood followed rules described by Desye based on studies by Schafer and Danzer.

Therapeutic Applications of High Frequency Currents

Professor d'Arsonval · 1932

He defined high frequency current as an alternating current reversing several million times per second instead of 80 to 100. Therapeutic currents of 4 to 6 million reversals per second produced only warmth at high intensity and caused no sensation, pain, or muscle contractions even at 3 amperes. First clinical diathermy application in 1896 at Hotel Dieu showed convincing results, but the procedure took sixteen years to be adopted from Germany and Austria.

THE PATHOLOGICAL ACTION OF LIGHT UPON THE EYE

W. STEWART DUKE-ELDER · 1926

Rabbit experiments showed that 2-5 minutes of exposure to a quartz mercury lamp produces conjunctivitis and corneal stippling. The human eye is more sensitive than the rabbit eye, and the reaction varies directly with exposure time and inversely with the square of the distance. Repeated exposures are additive for up to 24 hours if the interval is not long enough for physiological repair.
