[Use of chromogenic substrates for estimation of indicators of kallikrein-kinin and blood coagulation systems in blood plasma of patients with nephrotic syndrome]. 1983

A distinct increase of kallikrein content in blood plasma of patients with nephrotic syndrome as well as activation of thrombin simultaneously with a decrease in the prothrombin level were recorded in samples with synthetic chromogenic substrates S-2160 (Bz-Phe-Val-Arg-pNa), S-2238 (D-Phe-Pip-Arg-pNA) and S-2302 (D-Pro-Phe-Arg-pNA). Limited proteolysis of prothrombin by blood plasma kallikrein appears to be among the possible reasons of thrombin activation in the patients with nephrotic syndrome. Activity of plasmin, measured with S-2251 (D-Val-Leu-Lys-pNA) as a chromogenic substrate, was practically unlatered in blood plasma of these patients.

UI MeSH Term Description Entries
D007610 Kallikreins Proteolytic enzymes from the serine endopeptidase family found in normal blood and urine. Specifically, Kallikreins are potent vasodilators and hypotensives and increase vascular permeability and affect smooth muscle. They act as infertility agents in men. Three forms are recognized, PLASMA KALLIKREIN (EC 3.4.21.34), TISSUE KALLIKREIN (EC 3.4.21.35), and PROSTATE-SPECIFIC ANTIGEN (EC 3.4.21.77).

D007700 Kinetics The rate dynamics in chemical or physical systems.
D007705 Kinins A generic term used to describe a group of polypeptides with related chemical structures and pharmacological properties that are widely distributed in nature. These peptides are AUTACOIDS that act locally to produce pain, vasodilatation, increased vascular permeability, and the synthesis of prostaglandins. Thus, they comprise a subset of the large number of mediators that contribute to the inflammatory response. (From Goodman and Gilman's The Pharmacologic Basis of Therapeutics, 8th ed, p588) Kinin
D009404 Nephrotic Syndrome A condition characterized by severe PROTEINURIA, greater than 3.5 g/day in an average adult. The substantial loss of protein in the urine results in complications such as HYPOPROTEINEMIA; generalized EDEMA; HYPERTENSION; and HYPERLIPIDEMIAS. Diseases associated with nephrotic syndrome generally cause chronic kidney dysfunction.
