[Metabolism of sialoglycoproteins of the stomach of rats with experimental diabetes].

Experiments on white non-inbred male rats studied gastric sialoglycoprotein metabolism. It was found that rats with experimental (alloxan) diabetes exhibit enhanced catabolic processes in sialoglycoprotein metabolism characterized by elevated concentrations of free, oligobound sialic acids and sialidase activity in insignificantly elevated concentrations of protein-bound sialic acids.

[Changes in metabolism of sialoglycoproteins of the rat stomach during long-term immobilization stress and glucocorticoid hormone deficiency].

The effect of glucocorticoid hormone deficiency (caused by administration of chlordithane) on the methabolism of gastric sialoglycoproteins at the prolonged immobilized stress was investigated in male albino rats. Under conditions of prolonged deficit of glucocorticoid hormones (> 10 days) the imobilised stress caused higher increase of catabolic processes of sialoglycoproteins than in rats with normal level of glucocorticoids.
