Studies in asphyxia : 1, neuropathology resulting from comparatively rapid carbon-℗Ưmonoxide asphyxia; 2, neuropathology resulting from comparatively slow carbon-℗Ưmonoxide asphyxia; 3, neuropathology resulting from comparatively slow carbon-℗Ưmonoxide asphyxia, reaction during 16 to 165 days after exposure; 4, neuropathology resulting from comparatively rapid asphyxia by atmospheres deficient in oxygen; 5, blood chemistry changes resulting from comparatively rapid asphyxia by atmospheres deficient in oxygen; 6, blood chemistry of dogs after comparatively rapid carbon℗Ư-monoxide asphyxia.
