[The concentration of cerebral natriuretic peptide in tear and blood serum.].

The natriuretic peptides regulate pressure and water metabolism in human organism. The concentration of N-thermal cerebral natriuretic propeptide (NT-proBNP) in tear and blood serum was analyzed. The sampling included 49 patients divided on three groups.

[The relationship between content of malonic aldehyde, activity of glutathione peroxidase and polymorphism of gene GPX4 (718C/T) under chronic hepatitis C].

The study was carried out to evaluate concentration of malonic dialdehyde and activity of glutathione peroxidase in blood serum in their relationship with biochemical tests of functional conditions of liver; data of fibroelastography and polymorphism of gene GPX4 (718C/T) in patients with chronic hepatitis C. The sampling consisted of 100 patients with chronic hepatitis C. The control group included 80 healthy donors.

[The concentration of procalcitonin in blood andi enteric exudation in patients at early post-operation period].

The study sampling included 46 patients operated on the occasion of acute surgical pathology of abdominal organs. The concentration of procalcitonin was analyzed at 2-3 days after operation in simultaneously obtained samples of blood serum and exudation of small intestine. The level of procalcitonin was analyzed using enzyme-linked immunosorbent assay with test-systems with sensitivity 0.
