title: [Electrophoretic and enzymatic analysis of glycosaminoglycans in the blood serum of patients with hyperthyroidism].
abstract: An effect of hyperthyroidism on the composition and levels of glycosaminoglycans in the blood serum was studied. Glycosaminoglycans isolated from 1-ml blood samples were assayed with the following techniques: carbazole, electrophoretic and enzymatic. Separation and assay of particular GAG were made with bidirectional electrophoresis. Isomers of the remaining chondroitin sulphates were assayed enzymatically. Electrophoretograms of GAG in blood serum of healthy women have shown two fractions: low sulphate chondroitin sulphate and chondroitin-4-sulphate. The same fractions of GAG were found in blood serum of the female patients with hyperthyroidism. Mean concentration of GAG in the blood serum of hyperthyroid patients increased by 51%: low sulphate chondroitin sulphate and chondroitin-4-sulphate concentrations increased by 22% and 190% respectively. Chondroitin sulphates in the blood serum of both groups were degraded to unsaturated disaccharides not containing sulphur and unsaturated 4-sulphate disaccharides. Concentrations of unsaturated 4-sulphate and unsaturated sulphur-free disaccharides increased by 71% and 17% in hyperthyroidism. Observed changes in the blood serum GAG concentrations reflect changes in the connective tissue metabolism in hyperthyroidism.
