Abstract
Differences in the coagulation and fibrinolytic system of rats fed a fish oil based diet (fish oil diet) and fed a soybean oil based diet (control diet) were determined. Concentrations of plasma lipids were depressed in rats fed the fish oil diet. Prothrombin time (PT) and activated partial thromboplastin time (APTT) of rats fed the fish oil diet were longer than for the rats fed the control diet. Fish oil intake lowered the activities of most of the blood coagulation factors, and strongly depressed the factors involved in the intrinsic pathway. Fish oil also affected the fibrinolysis of rats. Plasminogen activator inhibitor (PAI) activity was elevated in rats fed the fish oil diet. In this study, both blood coagulation and fibrinolysis were down-regulated by feeding the fish oil diet.
