Lipid Peroxidation and Experimental Disseminated Intravascular Coagulation in Rats Induced by Endotoxin

Summary

The experimental model of disseminated intravascular coagulation (DIC) in rats induced by a 4 hr sustained infusion of 100 mg/kg endotoxin was used to study the relationship between lipid peroxidation and DIC. Serum thiobarbituric acid (TBA) reactive substances, important and damaging products of lipid peroxidation, increased gradually during the infusion of endotoxin. The levels of TBA reactants in serum, abdominal aortic wall and ileum mucosa were significantly increased in rats infused with 100 mg/kg of endotoxin for 4 hr, as compared with the control rats continuously given 11.4 ml of physiological saline for 4 hr. However, the levels in liver and kidney tissues, and in gastric, jejunum and colon mucosa did not increase significantly.
