title: [The blood flow and oxygen tension in the brain of Horsfield's terrapin (Agrionemys horsfieldi) in hyper- and hypothermia].
abstract: The dynamics of cerebral blood flow and oxygen available were studied in alert Middle Asia tortoises at high and low body temperatures. Local and total cerebral blood flow and oxygen available were found to depend on heating or cooling of the tortoise. Alterations in the values of cerebral blood and oxygen supply, pH value of the arterial blood sand packed cell volume suggest that metabolic factors participate in the regulation of cerebral blood flow in reptiles.
