[Hematoencephalic barrier function during irradiation under hypo- and hyperoxia].
The hematoencephalic barrier status was shown to change depending upon radiation dose and time after exposure. Synergism, additivity, and antagonism were observed after the combined effect of radiation and a changed gas medium. On the whole, hypoxic hypoxia, as opposed to air and oxygen, had a slight radioprotective effect, but after 5 h, no variations were virtually found in the groups animals exposed to superlethal radiation doses in different gas media.
