Risultati di ricerche sulla influenza di microonde di λ = 60-70 cm. sui vegetali

Salotti, A., Fiorenzi · 1934

Researchers investigated whether microwaves of 60-70 cm wavelength influence germination and growth of various seeds, particularly wheat. In systematic experiments, 150 wheat seeds per experiment received various doses over multiple days from a 5 W oscillator, and the results were completely negative.

Action des ondes électro-magnétiques sur les matières colorantes photodynamiques dans le coeur des batraciens

Roffo, A. S., Jr. · 1934

Researchers tested neutral red, methylene blue, erythrosin, and eosin on batrachian hearts. Irradiated solutions may exert a much stronger action on the hearts of batrachia than non-irradiated solutions. The substances acted on the auriculo-ventricular and intraventricular systems, provoking A.V. and I.V. blocks with diminished systolic amplitude.

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.

A proposito di generatori diatermici a onde corte

Reviglio, G. M. · 1934

The speaker emphasized the advantages of short wave diathermic generators and claimed they represent a real progress from a physical point of view. Clinical experience will show whether they are a real therapeutic progress, though the speaker is inclined to believe so based on theoretical considerations and treated cases.

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.

DEVELOPMENT AND FORM OF SHORT WAVE THERMAL ZONES IN AN AGAR BODY

Albrecht, W. · 1934

Researchers used a 4 per cent. agar block with a thermoindicator turning at 37 degrees C to visualize thermal zones generated by a short-wave condenser field of 3.96 m wavelength. Round condenser plates insulated by glass hooks, with diameters of 25 up. to 10 mm., heated agar layers 10-50 mm thick. When plates of equal size were used, the heated zone was band-shaped and practically the same width as the plates; when a large and a small plate were placed opposite each other, a truncated cone thermal zone formed with its borderline nearly matching the exterior connecting line between the plate surfaces.

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.
