Antithrombin III (ATIII) is the main inhibitor of the coagulation proteases like factor Xa and thrombin. Anticoagulant activity of ATIII is increased by several thousand folds when activated by vascular wall heparan sulfate proteoglycans (HSPGs) and pharmaceutical heparins. ATIII isoforms in human
The difference between absorption of unfractionated heparin (UFH) and low molecular weight heparin (LMWH) after oral and oral cavity administration were studied respectively, and the compatible enhancer for oral cavity delivery system of both drugs was found. The LMWH and UFH films were prepared
35S-labelled heparins were recovered from adipose tissue, hearts, lungs, peritoneal cavities and skins of rats given H2(35)SO4. Their purification involved incubation with Pronase, precipitation with cetylpyridinium chloride in 1.0 M-NaCl, gradient elution from DEAE-Sephacel and incubation with
Our studies aimed at determining a loss of active heparin from the peritoneal cavity after its intraperitoneal administration (250 JU/l of dialysis fluid) in 16 patients treated because of the end-stage renal failure with intermittent peritoneal dialysis and at comparing heparin influx clearance
Hepatocyte transplantation is being explored as a treatment strategy for end-stage liver disease; however, the main limitation is the insufficient vascularization of transplanted hepatocytes. To overcome this problem, a suitable 3D microenvironment and the types of transplanted cells must be
BACKGROUND
The antithrombin-heparin/heparan sulfate (H/HS) and thrombin-H/HS interactions are recognized as prototypic specific and non-specific glycosaminoglycan (GAG)-protein interactions, respectively. The fundamental structural basis for the origin of specificity, or lack thereof, in these
To evaluate the effectiveness of heparin and heparin fractions in decreasing abscess formation, rats were divided into six groups. A fibrin clot containing 10(9) live Escherichia coli was placed in the peritoneal cavity of each rat. Group 1 (controls) received daily subcutaneous (SQ) injections of
The effect of heparin upon the clinical and pathologic course of experimentally induced peritonitis in the rat was studied. Peritonitis was induced in 40 rats by creating a closed ileal loop 4 centimeters long at a distance of 5 centimeters from the ileocecal valve. The rats were divided into two
Injury to the central nervous system causes glial reactions, which eventually lead to the formation of a glial scar and inhibit axonal regeneration. The present study aimed to reduce the extent of glial scar formation in injured cerebral cortex using heparin hexasaccharide (6-mer) and octasaccharide
Cranial neural tube defects occur when heparin is added to the culture media of postimplantation rat embryos undergoing organogenesis in vitro. Timed-exposure studies were undertaken to determine whether the defects caused by heparin were the result of defective folding and fusion of the neural
