Urine proteins after burn injury

Two-dimensional immunoelectrophoresis was used to examine the proteins present in urine during the first week following burn injury. Of the "serum" proteins present in the urine some glycoproteins were found to be in different relative proportions from those observed in serum. In patients sustaining severe burns the amount of protein excreted was increased compared to patients with mild burns and to controls. alpha 1-Antichymotrypsin detected in the urine of patients with severe burns was at times seen as a twin peak. This altered peak was of slower electrophoretic mobility and may represent a polymer of the protein or a complex of the protein with some other, possibly tissue-derived, protein.
