- W2001097744 abstract "We have used phase-contrast microscopy to determine a necrotic end point of the order of minutes in primary hepatocytes exposed to oxyradicals generated with xanthine oxidase plus hypoxanthine. This study examines whether the morphologic end point thus determined agrees with other criteria of cell necrosis. When 95–100% of the cells were shown to be necrotic by our morphologic assay, transmission electron microscopy confirmed definitive subcellular evidence of cell death, trypan blue exclusion revealed a 92% loss in the ability of cells to exclude the dye, and there was a 47% specific release of 51 Cr (versus a 50% theoretical value). In contrast, the appearance of extracellular aspartate aminotransferase activity was relatively slow and did not corroborate the morphologic end point. In summary, we have validated the morphologic end point in our cell-based assay of oxyradical damage.Key words: necrosis, oxyradical damage, hepatocyte, validation." @default.
