title: Prevention of postoperative adhesions by tissue-type plasminogen activator (t-PA) in the rabbit.
abstract: The fibrinolytic system of the peritoneum is important in the pathogenesis of adhesions. Plasminogen activator activity is depressed by serosal types of injury, which cause ischemia. Ischemic peritoneum induces fibrinous adhesions. When local fibrinolytic activity is impaired, persistence of fibrin and organisation of the fibrinous adhesions may occur. Peritoneal adhesion in rabbits were created by drying the serosa of the uterine horns and by introducing a small amount of blood intraperitoneally. In one group of rabbits tissue-type plasminogen activator (t-PA) was given intraperitoneally at the end of the operation: another group served as controls. 48 rabbits were operated on. The animals were killed 3 h, 1, 3 and 7 days postoperatively for evaluation of adhesions. All animals of the control group had adhesions. The animals of the t-PA group had less adhesions than the animals of the control group.
