ON THE PARALYSIS CAUSED BY THE NITROGLYCOL POISONING

Abstract

The Paralysis occurs in the hand in most of the cases, and it occurs after midnight while the patients are asleep or in the early morning after they get up. Disorders of the autonomic nervous functions have been found in 40% of the paralyzed cases by means of the pressure methods after Ashner and Czermak. Decrease of the pulse pressure has been confirmed in 61.9% of the cases by the cold-pressor test after Hines-Brown. This may serve to understand the turning pale of the fingers by exposure to cold wind outdoors. Fragility of capilaries has been ascertained by Delta-petechiometer, which revealed in 56% of the paralyzed and in 30% of the non-paralyzed 10 and more petechie at negative pressure 200mmHg of for one minute. Anemia combined with has been found in 24 of the cases, suggesting no special relation with anemia. Central relative scotoma for red has been found in 47% of the paralyzed, and dilatation or winding of the retinal in 53% of the cases. The diastolic pressure in such cases is decreases·These findings may serve to understand drug narcosis and hypotension which are common among them. There are no abnormality in the leucocyte counts and in the percentage of their classification.
