Background: This study assessed the peritoneal fibrinolytic response during the first week after colonic surgery in rats with and without bacterial peritonitis, and possible modulation of the response by two hyaluronan-based antiadhesive agents. Methods: A colonic anastomosis was constructed in 90 male Wistar rats. Peritonitis was induced in...

Several clinical studies have demonstrated an inverse relationship between circulating levels of estrogen and tissue-type plasminogen activator (t-PA). The present study was designed to test the hypothesis that estrogen lower plasma levels of t-PA by increasing its clearance from the bloodstream. 17α-Ethinyl estradiol (EE) treatment resulted in...

The fibrinolytic activity of blood is to a large extent determined by the plasma level of tissue-type plasminogen activator (t-PA). Changes in the plasma level of t-PA are mainly achieved by the endothelium by two mechanisms: (a) a rapid, short-term release of t-PA, which occurs within minutes (acute release, regulated secretion) and (b) a long...

Pharmacological modulation of the in vivo induction of plasminogen activator inhibitor type-1 (PAI-1) synthesis was studied in rats using the induction of PAI-1 by endotoxin as a model system. Both the cyclooxygenase inhibitors acetylsalicylic acid and indomethacin enhanced PAI-1 induction. The combined cyclooxygenase-lipoxygenase inhibitor,...

Tissue-type plasminogen activator (t-PA) and its inhibitor, plasminogen activator inhibitor 1 (PAI-1), play an important role in regulating the fibrinolytic capacity of plasma. Both t-PA and PAI-1 are synthesized by the endothelium. We report that retinoic acid (vitamin A acid) and other retinoids rather specifically stimulate the production of...

The acute release of tissue-type plasminogen activator (t-PA) was studied in perfused rat hindlegs. Pretreatment of rats with the protein synthesis inhibitor cycloheximide (2 mg/kg) at 1, 3 or 5 h prior to perfusion of rat hindlegs did not influence the amount of t-PA released by platelet-activating factor (20 nM) or bradykinin (1 μM). The...
