THE ROENTGEN RAY IN OTOLARYNGOLOGY

Roentgen Ray Intoxication

These experiments show that the common laboratory animals are about equally sensitive to the x-ray given over the abdomen. The clinical reaction following a M.L.D. is very similar and the intestinal pathology almost identical. The rat and guinea pig are slightly more sensitive to the x-ray than are the dog, cat, and rabbit. By contrast birds, frogs, and reptiles are very resistant to the x-ray ...

A Study of Renal Function in Roentgen Ray Intoxication

Our experiments give no support to the current belief that an x-ray nephritis may be produced by direct or indirect action of the hard Roentgen rays. Moderate doses of x-rays given repeatedly over considerable periods of time have no demonstrable influence on renal function or renal structure. With x-ray exposures of the abdomen and shielding of the kidneys fatal intoxication may be produced wi...

Dilatation and Pulsation of the Left Subelavian Artery in the Roentgen-Ray Diagnosis of Coarctation

Postero-anterior chest roentgenograms in 17 of 20 patients with coarctation of the aorta showed widening of the left upper mediastinal shadow attributed to dilatation of the left subclavian artery; pulsations of this vessel were evident in 12 of 13 cases with roentgenkymograms. In 3 of the latter cases rib notching was absent or equivocal. The subclavian pulsations may be observed fluoroscopica...
