Effects of gabexate mesilate on the reactions of lipid metabolism in endotoxic shock

Advances in Shock Research

Abstract

Endotoxic shock was induced in rabbits of either sex by IV injection of 50 micrograms/kg endotoxin (ET) extracted from E coli O-55 by Boivin's method. A polyvinyl catheter was introduced into the superior vena cava under local anesthesia 1 day prior to the experiments. We observed a rise of plasma-free fatty acids (FFA) from an initial mean value of 190 muEq/liter to a level of 290 muEq/liter within 6 h after injection of endotoxin. The increase of FFA was followed by a rise of plasma triglycerides (TG) and an increase of very low-density lipoproteins (VLDL), beginning 1-2 h later. The rise of FFA and the following increase of TG and VLDL were significantly reduced by infusion of 14 micrograms/kg X min gabexate mesilate (GM). Our results indicate that GM--in addition to its well-known proteinase inhibitory action--effects fatty acid metabolism.

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.

ApoE, Lipids & Cholesterol

Serum cholesterol, triglycerides, apolipoprotein B (APOB)-containing lipoproteins (very low-density lipoprotein (VLDL), immediate-density lipoprotein (IDL), and low-density lipoprotein (LDL), lipoprotein A (LPA)) and the total cholesterol/high-density lipoprotein (HDL) cholesterol ratio are all connected in diseases. Here is the latest research.
