    Abstract:
    We studied the involvement of coagulation and fibrinolysis system in the induction and development of atherosclerosis in rabbits with hyperlipidemia induced by a high-cholesterol diet (HCD). In HCD rabbits, plasma lipids and atherogenic indices were maintained at a high level throughout the experimental period compared with those in rabbits fed on a standard diet. In the early phase, a significant increase in fibrinogen level was followed by increases in the activities of plasminogen and tissue-type plasminogen activator with a decrease in alpha 2-plasmin inhibitor activity and platelet count. In the middle and late phases, significant increases in plasminogen activator inhibitor-1 and antithrombin-III were observed in HCD rabbits. These results suggest that the early enhancement of coagulation followed by high activity of fibrinolysis is involved in the induction and development of hyperlipidemic thromboembolism and atherosclerosis in HCD rabbits.
