Abstract

The aim of this study was to examine whether glycosaminoglycan (GAG) from Mactra veneriformis had an impact on the protein C (PC) system in rats and expression of relevant factors in human umbilical vein endothelial cells. Isotonic saline, heparin sodium (4 mg/kg), and GAG (1, 4, and 16 mg/kg) were administered to Wistar rats through caudal vein at the total volume of 0.5 ml for each injection, and the anticoagulant blood was prepared. The activities of PC and protein S, and the concentrations of activated protein C inhibitor (APCI) and thrombomodulin were detected according to the kit instructions. The expression levels of tissue factor, tissue factor pathway inhibitor and thrombomodulin genes in human umbilical vein endothelial cells were detected by the reverse transcription polymerase chain reaction method. GAG could significantly reduce the activity of PC (P < 0.05, P < 0.01) and slightly increase the concentration of APCI, and high concentration of GAG could significantly decrease the activity of protein S (P < 0.05) and significantly increase the concentration of thrombomodulin (P < 0.05). GAG could significantly downregulate the expression level of tissue factor gene (P < 0.05, P < 0.01) and significantly upregulate the...Continue Reading

Aminoglycosides (ASM)

Aminoglycoside is a medicinal and bacteriologic category of traditional Gram-negative antibacterial medications that inhibit protein synthesis and contain as a portion of the molecule an amino-modified glycoside. Discover the latest research on aminoglycoside here.

Blood Clotting Disorders

Thrombophilia includes conditions with increased tendency for excessive blood clotting. Blood clotting occurs when the body has insufficient amounts of specialized proteins that make blood clot and stop bleeding. Here is the latest research on blood clotting disorders.
