[Renal excretion of glycosaminoglycans under normal conditions and in several nervous system diseases in children]. / Pochechnaia ékskretsiia glikozaminoglikanov v norme i pri nekotorykh zabolevaniiakh nervoi sistemy u detei

The authors studied 101 children with diseases of the nervous system (with hereditary and acquired pathology) and 205 practically normal children. The urine excretion of specific components of the connective tissue (glycosaminoglycanes) was higher than in normals. Lesions of the connective tissue stroma in such forms of pathology is expressed not only in quantitative changes of glycosaminoglycane, but in their qualitative characteristics. Disturbances of the fractional compounds of glycosaminoglycane in the urine of patients differs from the parameters of chromatograms of normals by a high content of fractions of heparansulfate in a relatively low level of chondroethylsulfatolike fractions. In such states the severity of the clinical picture is accompanied by expressed metabolic disturbances.
