Extracellular acidosis (ph 5.9 to 6.5) was found to be significantly retard the subcellular response of Ehrlich ascites tumor cells (EATC) to anoxic injury. The cells initially showed a reversible stage of cell injury with diffuse mitrochondrial condensation and swelling of endoplasmic reticulum (ER) at pH 7.9 by 1 h, while by 3 h at this pH all cells showed high amplitude and intramatrical flocculent densities of mitochondria, and fragmentation of membrane systems. At pH 7.4 cells were normal at 15 min., the mitochondria were condensed as above by 1 h, some cells still showed condensed mitochondria and dilated ER while others showed high amplitude swelling of mitochondria by 3 h and all cells showed irreversible changes by 4 h. At pH 5.9 to pH 6.5 mitochondria remained condensed until 3 h and only by 6 h did some cells show high amplitude swelling, whereas most cells showed persistent mitrochondrial condensation. Not until 8 h did all cells show high amplitude swelling of mitochondria. Furthermore, ultrastructural differences in the pattern of necrosis were seen at the lower pH values consisting of greater density of the cell sap, irregularly dispersed flocculent densities in apposition to fragmented cytoplasmic membranes and in mitochondria, and more prominent persistent clumping of nuclear chromatin.
