Atypical and anaplastic meningiomas--does the new WHO-classification of brain tumours affect the indication for postoperative irradiation?

abstract：:In anaesthetized artificially ventilated dogs, the effect of graded arterial hypoxaemia on cerebral blood flow (CBF) and on the oxidative carbohydrate metabolism of the brain was tested. It is shown that the hypoxic vasodilatory influence on cerebral vessels is present even at moderate systemic hypoxaemia, provide tha...
