Regional cerebral blood flow and regional metabolism in cold induced oedema.
24 hours following a cold induced oedema in cats rCBF was measured in the lesion area, the bluish stained cortex immediately adjacent to the lesion, a cortical area remote from the lesion, and in the contralateral uninjured hemisphere. Thereafter the brain was frozen and the respective tissue areas were removed and analyzed for water and electrolyte content as well as metabolite concentrations. It seems, that in the neighbourhood of a local lesion at least 3 different brain regions can be differentiated with regard to their characteristic pattern of data. In non-oedematous regions either hyperaemia or hypoaemia could be observed. In areas with local brain oedema rCBF was reduced inversely p…
Arterial pCO2 and Blood Flow in Different Parts of the Central Nervous System of the Anesthetized Cat
It cannot be regarded as proven that the mechanisms involved in the regulation of local circulation are identical in all parts of the central nervous system. Evidence has been presented that carbon dioxide exerts differential effects in different parts of the CNS [2, 3, 7, 10].
Effect of arterial oxygen tension on cerebral blood flow at different levels of arterial PCO2.
Die Wirkung des arteriellen O2-Partialdruckes auf die Durchblutung des Grosshirns, Kleinhirns und Hirnstammes bei normalen und erhohten CO2-Partialdrucken im arteriellen Blut wird an der anaesthesierten Katze untersucht. Die Wirkung des PaO2 ist von der Hohe des PaCO2 abhangig.
