title: [Oxygenation of glioblastomas and normal brain tissue during radiation therapy].
abstract: Eight patients underwent simultaneous polarographic studies of pO2 in the brain normal tissue and glial tumors under the conditions of inhaling 100% oxygen and a hypoxic gaseous mixture (10% of oxygen and 90% of nitrogen). It has been established that the inhalation of 100% oxygen causes an increase in pO2 in the brain normal tissue and tumor by 100-115%. A short-term moderate gaseous hypoxia leads to a decrease in pO2 both in the brain normal tissue and tumor by 30% on an average.
