title: Changes in capillary permeability during severe experimental acute pancreatitis in rats.
abstract: Abnormalities of microcirculation are thought to have an important role in the pathogenesis of severe acute pancreatitis (SAP) and in the associated multiple organic failure. We studied changes in capillary permeability during experimental SAP in rats. Necrotizing acute pancreatitis was induced by retrograde injection of sodium taurocholate in pancreatic ducts in rats (n = 30). The animals were distributed in three groups in which the spaces of compartmental distribution as well as the tissue distribution of labeled tracers were evaluated with the use of erythrocytes and albumin tagged with radioactive chromium, apart from determining the volume of total body water. All the studies were carried out four hours after the induction of acute pancreatitis and the administration of radioactive tracers.
