Experimental studies were performed to elucidate the significance of various physiological factors contributing to the pathogenesis of carbon monoxide (CO) encephalopathy, such as systemic blood pressure (BP), common carotid artery blood flow (CF), local blood flow (LBF) of the brain and blood gas including pH, and to analyse the morphological character of(More)
Twenty-eight mature cats were exposed to 0.3% carbon monoxide (CO) gas for 90-193 min using artificial ventilation. The systemic blood pressure (BP), venous pressure (VP), blood flow of the left common carotid artery (CF), and blood gas were monitored. The local blood flow (LBF) of the globus pallidus, putamen, or claustrum was measured by the hydrogen(More)
Since in a previous study hypoxia and subsequent hypotension were considered to be essential for the pathogenesis of carbon monoxide encephalopathy (CO-encephalopathy), experiments were conducted to see whether a combination of nitrogen hypoxia and subsequent systemic hypotension of similar degree and duration as in the previous experimental CO poisoning(More)
The cerebral and cerebellar lesions of the cats that were exposed to 0.3% carbon monoxide gas under artificial respiration were examined by an electron microscope at different intervals. During the first few days, the most outstanding features were segmental empty axonal swelling, dilatation of the extracellular space, swelling and necrosis of astrocytes(More)
A study was performed to elucidate the significance of various physiological factors contributing to the pathogenesis of experimental cyanide encephalopathy, such as the systemic arterial blood pressure, venous pressure, common carotid blood flow and local blood flow of the cerebral grey and white matters, and blood gas including pH. The histology and(More)

The change of Grinker's myelinopathy in carbon monoxide (CO) poisoning occurs not only in patients with the clinically diphasic type of CO-poisoning but is also found around the destructive lesions in patients with the acute form of CO-poisoning. The distribution of this myelinopathy is similar to that of the acute form of CO-poisoning. The cerebral change(More)
A study was conducted to investigate the hydrodynamics of branching flow in relation to the blood supply to the basal part of the brain. A series of measurements of the branching loss-coefficients under laminar steady flow were conducted using model branches with various geometries, and the effect of branching on blood supply to distal areas was described(More)
