Male Sprague-Dawley rats were anesthetized and subjected to sham or hemorrhage to 30 mmHg for 30 min followed by reperfusion. All rats were placed on TPN for 5 days, then underwent laparotomy for in vivo renal artery and aortic blood flow for 60 min. The kidney was perfused in vitro with Krebs-Henseleit buffer at 3 ml/min (pH 7.4, 37 degrees C) and venous effluent was collected for analysis of PGE2, 6-keto-PGF1 alpha and thromboxane B2 by EIA. Hemorrhage/reperfusion followed by TPN for 5 days increased renal PGE2 2-fold and decreased in vivo renal artery blood flow by 50% compared to the sham group. Hemorrhage/reperfusion followed by TPN did not alter release of the other eicosanoids measured. These data suggest that the kidney has a limited capacity to maintain renal blood flow by increasing release of PGE2 when the animal is subjected to long-term resuscitation with TPN following mild hemorrhage/reperfusion injury.","PeriodicalId":20659,"journal":{"name":"Prostaglandins, leukotrienes, and essential fatty acids","volume":"44 1","pages":"335-9"},"PeriodicalIF":3.0,"publicationDate":"1995-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90674436","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Anesthetized Sprague-Dawley rats (300 g) were subjected to sham or superior mesenteric artery occlusion for 20 min followed by 30 min of reperfusion. The ischemia/reperfusion groups received either enteral allopurinol (10 mg/kg) daily for 5 d prior to ischemia, pentoxifylline (50 mg/kg) 10 min prior to ischemia or carrier. The kidney was removed and perfused in vitro with oxygenated Krebs buffer and the effluent was assayed for release of 6-keto-PGF1 alpha, PGE2 and thromboxane B2 (TXB2) by enzyme immunoassay. Mesenteric ischemia/reperfusion decreased renal PGE2 release by 50% (compared to sham) but did not alter release of TXB2 or 6-keto-PGF1 alpha. Pentoxifylline pretreatment (not allopurinol) preserved renal PGE2 release at the sham level. These data showed pentoxifylline exerted a protective effect against severe mesenteric ischemia/reperfusion injury by maintaining release of renal PGE2, a potent endogenous renal vasodilator.","PeriodicalId":20659,"journal":{"name":"Prostaglandins, leukotrienes, and essential fatty acids","volume":"7 1","pages":"41-8"},"PeriodicalIF":3.0,"publicationDate":"1994-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74746794","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
