title: The importance of NPSH on the radiosensitizing effect of oxygen in Chinese hamster V-79 cells.
abstract: The radiosensitivity of Chinese hamster V-79-171B fibroblasts increased more rapidly with increasing partial pressure of oxygen when the cell cultures had low endogenous levels of non-protein sulphydryl (NPSH), about 5 mumol per cell compared with about 15 mumol per cell. There was a good correlation between initial NPSH content and sensitization by oxygen concentrations between 0.06 and 0.7 per cent.
