[Contribution of free-radical reactions of chamber humor to the development of primary open-angle glaucoma].

The level of lipid peroxidation products (malonic dialdehyde) is more than two times increased in the anterior chamber humor in patients with far advanced glaucoma in comparison with the well-developed stage. The level of the total antioxidant activity of humor is reliably lowered. A correlation has been revealed between the antioxidant activity of humor and its production.

[Enzyme proteins of different classes of northern red-backed and large-toothed red-backed voles].

Electrophoretic characters of 9 enzyme systems from different tissue homogenates supposedly controlled by 17 loci are described. Polymorphism detected in loci for glutamate-oxalate transaminase, adenylate kinase, esterase D. glucosephosphate isomerase was thoroughly investigated.

[Soluble blood proteins and hemoglobin from red-backed and large- toothed voles].

Electrophoretic pattern of serum proteins of northern red-backed and large-toothed voles was examined. Seven main protein zones were distinguished. In four of them variability was observed, possibly genetically determined.
