title: [DNA degradation and changes in the permeability and form of Ehrlich ascites tumor cells when incubated in an anaerobic medium without glucose].
abstract: After a 3-hour incubation of the Ehrlich ascite tumor cells in buffered Hanks solution, without glucose and oxygen, the extensive cell injuries were observed. The time-course of appearance of these injuries was as follows: cell blebbing, staining of the cells with trypan blue, and then their staining with ethidium bromide. The DNA degradation registered with fluorometric method coincided in time with cell staining with trypan blue. All injuries (except DNA degradation) were delayed at pH 6.0 compared with those at pH 7.3. Glucose added to the cell suspension greatly protected the cells from these injuries, although DNA degradation at pH 6.0 in these conditions was a little higher than that at pH 7.3.
