title: [Changes in the permeability of the blood-brain barrier after combined exposure to gamma-radiation and a modified gas medium].
abstract: An equation was obtained representing the time of penetration of acid fuchsin into the mouse brain as a function of: (i) radiation dose given to head, (ii) radiation dose given to body, and (iii) per cent of oxygen in a gas medium during exposure. Within the dose range from 1,29 to 2.58 C/kg, irradiation of the body increased the permeability of hematoencephalic barrier more significantly than irradiation of the head. A modifying action of hyperoxia and 8% hypoxic hypoxia was more pronounced with irradiation of the head.
