[Biopolymers in urine of patients with syringomyelia].

Urine of patients with syringomyelia was analysed by gel filtration, ion-exchange chromatography and analytical chemistry methods. Increased level of acidic glycoproteins and decreased level glycosaminoglycans levels were found. Patients with syringomyelia had smaller glycosaminoglycans components of proteoglycans than normal subjects.

[Content and metabolism of glycosaminoglycanes in organs and tissues of different aged white rats].

Glycosaminoglycanes content was decreased in liver, brain and skin of white rats during ageing due to the decrease of non-sulfated fraction. Sulfated glycosaminoglycanes synthesis intensity was decreased too. These pathochemical processes were more expressed in skin and liver than in brain.

[Are-related changes in content of glycosaminoglycans in female skin].

Postmortem skin samples of 50 women aged from 15 to 90 years were analysed. Protein and DNA levels were stable and rather age-independent. Glycosaminoglycane (GAG) level decreased during ageing according to linear regression equation: Age = 100.

[Age changes in glycosaminoglycan level in the woman skin].

Postmortem skin samples of 50 women aged from 15 to 90 years were analysed. Protein and DNA levels were stable rather age-independent. Glycosaminoglycane (GAG) level decreased during ageing accordingly linear regression equation: Age = 100.

[Relation between cost and quality of production (e.g., the manufacturing of dental instruments)].

A conclusion on the necessity of developing the effective system of encouragement for the development and production of high-quality medical engineering was made with account of these articles on the basis of correlation between prices and quality of the production in the subbranch.
