Hexosamine, sialic acid, fucose, seromucoid, and protein levels of sera of some species.

Abstract

The levels of hexosamine and protein in human, rodent, bovine, porcine, and ovine sera, and the levels of sialic acid, fucose, seromucoid hexosamine, and seromucoid sialic acid in bovine, porcine, and Ovine sera were determined for a number of animals of different groups. In the porcine sera the levels of hexosamine, fucose, and seromucoid hexosamine and sialic acid were higher than in the sera of the other animals. The sera of bovine, porcine, and ovine immature animals contained significantly less protein and fucose than the sera of mature animals. In cows and pigs two and a half times more hexosamine and twice as much sialic acid were present in the seromucoid fraction isolated from the sera of immature than from the sera of mature animals. Some other differences between immature and mature animals were detected.The effect of chronic fluorosis on the hexosamine and protein contents of bovine serum was studied. Statistically significant depression of both serum hexosamine and protein in the animals affected by chronic fluorosis was observed. Some other conditions influencing the serum hexosamine and protein were investigated.
