Variation of alpha 1-antitrypsin glycoprotein microheterogeneity in hepatic postresuscitation disease.

Microheterogeneity of the glycoprotein alpha 1-antitrypsin has been investigated sequentially by high resolution isoelectric focusing in a child with the proteinase inhibitor MS phenotype after near-drowning. A band-splitting with additional cathodal fractions exhibited migration from the most cathodic to the anodic positions of the glycoprotein isoforms in the course of post-resuscitation disease. The pattern may reflect the time- and stage-dependent hypoxic and post-hypoxic effects on hepatocellular metabolic zonation.
