Abstract

We have examined the effects of an inhibitor of plasminogen activator inhibitor-1 (PAI-1) production, (3E,4E)-3-benzylidene-4-(3,4,5-trimethoxy-benzylidene)pyrrol idine-2,5-dione (T-686), on lipopolysaccharide (LPS)-induced death in mice. Oral administration of T-686 (10 and 100 mg/kg/day) for 8 days prior to the LPS injection (35 mg/kg, i.v.) protected mice from the lethal effect of LPS in a dose-dependent fashion. Moreover, treatment with 100 mg/kg T-686 attenuated the increase in plasma PAI-1 activity and the decrease in AT-III activity induced by LPS. We conclude that T-686 can reduce the mortality of mice induced by LPS, which seems to be partially correlated with both hypercoagulation and hypofibrinolysis.

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.
