The effect of X irradiation on rat parotid acinar cell function was evaluated in vitro 1, 3, and 7 days following in vivo exposure to 2000 R. Several cellular functions were followed: protein secretion (amylase release), ion movement (K+ efflux and reuptake), amino acid transport (α-amino[14C]isobutyric acid), and an intermediary metabolic response ([14C]glucose oxidation). In addition both the morphologic appearance and in vivo saliva secretory ability of parotid cells were assessed. Our results demonstrate that surviving rat parotid acinar cells, isolated and studied in vitro 1-7 days following 2000 R, remain functionally intact despite in vivo diminution of secretory function.
