background : cardiovascular operations are associated with an inherent bleeding tendency that sometimes leads to severe bleeding and transfusion requirement. pharmacological intervention to minimize post-bypass bleeding and blood product transfusions has received increasing attention from both medical and economic viewpoints. methods: this double-blind, randomized, placebo-controlled clinical t...

BACKGROUND The technique of deep hypothermic circulatory arrest (DHCA) for cardiothoracic surgery is associated with increased risk for perioperative blood loss and renal dysfunction. Although aprotinin, a serine protease inhibitor, reduces blood loss in patients undergoing cardiopulmonary bypass, its use has been limited in the setting of DHCA because of concerns regarding aprotinin-induced re...

Endogenous serine proteases have been reported to control the reabsorption of Na(+) by kidney- and lung-derived epithelial cells via stimulation of electrogenic Na(+) transport mediated by the epithelial Na(+) channel (ENaC). In this study we investigated the effects of aprotinin on ENaC single channel properties using transepithelial fluctuation analysis in the amphibian kidney epithelium, A6....

BACKGROUND Given the evidence accrued by other authors on beneficial effect of protease inhibitors on experimental immune nephritis, and following our preliminary report on abrogation of immune glomerulopathy in the rat by antifibrinolytic and antiproteolytic drug, epsilon-aminocaproic acid (EACA), we investigated the effect of this drug on the rat autologous anti-GBM nephritis. Along with the ...
