When Hb AIc was estimated by affinity chromatography where boron phenyl-agarose was used as a sorbent, the highest rate of Hb AIc binding with the sorbent was detected at pH 8.5-9.0 while the maximal elution of the protein occurred at 0.3-0.5 M concentration of sorbitol used as an eluent. Content of Hb AIc, estimated in 56 patients with insulin-dependent(More)
Cytokine-stimulated metabolism of sphingomyelin results in the accumulation of ceramide and sphingosine which play a part in the regulation of cell proliferation, differentiation, and reception, as well as in oncogenesis. Formation of TNF-alpha (a member of the cytokine family), accumulation of sphingosine, and DNA synthesis (measured by immunoblotting,(More)
Indirect immunoperoxidase assay and computer analysis of photographic images revealed more intensive expression of prolactin receptors in hepatocytes of women compared to men. The intensity of expression was maximum in secondary liver cancer, high in obstructive jaundice of different etiology, and less pronounced in cholelithiasis. The expression of(More)
Activities of main components of the kallikrein-kinin system: tissue (renal) and blood plasma kallikreins, kininases I and II, bradykinin-activating activity as well as free kinins, were estimated in urine of patients with latent and nephrotic forms of glomerulonephritis as compared with those parameters in urine of healthy persons. Content of tissue(More)
Activities of main components of KKS were estimated in the urine of patients with latent, nephrotic and hypertonic forms of chronic glomerulonephritis (ChGN) and compared to those parameters in urine of healthy persons. The data obtained allow to make a conclusion concerning the pathogenetic and the compensatory role of plasma KKS in the nephrotic form of(More)
The goal of this work was to study the expression of tumor necrosis factor alpha (TNFalpha), sphingomyelin cycle activation, and lipid peroxidation (LPO) processes after the removal of a cholestatic factor in the liver subjected to different durations of cholestasis. Restored bile flow after a 9-day hepatic cholestasis normalized sphingomyelinase (SMase)(More)
Several human granulocyte proteinases sensitive to the thermo- and acid-resistant proteinase inhibitor from rabbit serum (TASPI) were revealed, using TASPI-Sepharose 4B. It was found that TASPI inhibits the following human granulocyte proteinases: granules-localized kininogenase and chymotrypsin-like kininase (serine proteinases), elastase-like proteinase(More)
Elastase-like activity, alpha 1-inhibitor of proteinases and acid stable antitryptic activity were studied in blood of 26 patients and in synovial fluid of 11 patients with rheumatoid arthritis during acute stage of the disease and after treatment with salase pyridasine and orthophene. The higher values of the elastase-like activity were detected in(More)
Protein content was measured using ponceau S stain in "protein-free" urine (as shown by clinical analysis with sulfosalicylic acid) of 34 patients with insulin-dependent diabetes mellitus. In 15 patients (group 1) protein levels did not differ from those in healthy subjects. In 19 patients (group 2) protein levels surpassed the normal value by 3.6 times, on(More)
