[Quantitative isolation of acid mucopolysaccharides from urine in progressive scleroderma (author's transl)]

After filtration the urine was concentrated to about 1/10 of the original volume. The urine was centrifuged for 15 min at 5000 rev/min. The supernatant was chromatographed on Bio-Gel P-2-with a 10% aqueous solution of ethanol. Then the glycosaminoglycan fraction was separated into seven further fractions by chromatography on Dowex 1 X 2 and elution with increasing concentration of sodium chlorid. The desalted fractions were analysed. From the analytical data presented no definite correlation between excretion of glycosaminoglycans in urine and progressive scleroderma can be observed. These results were discussed with further data presented by Hexosamine determination.
