Decay-accelerating factor in guinea pig stomachs following ischemia reperfusion stress.
A complement regulatory protein, decay-accelerating factor (DAF, CD55), is known to protect host tissues from autologous complement activation. DAF is present on the apical side of human gastric epithelial cells, and its expression increases during gastritis. To develop an animal model for analysis of DAF expression on gastric cells, a mAb to guinea pig DAF was successfully used. Although DAF e...
متن کاملDecay-accelerating factor attenuates C-reactive protein-potentiated tissue injury after mesenteric ischemia/reperfusion.
BACKGROUND C-reactive protein (CRP) is an acute pro-inflammatory mediator that has been demonstrated to enhance ischemia/reperfusion (IR) injury by virtue of activating the complement system. CRP is able to interact with complement proteins such as C1q, complement factor H, and C4b-binding protein. Since complement activation is central in the expression of tissue injury following IR, we have i...
متن کاملHepatocellular oxidant stress following intestinal ischemia-reperfusion injury.
Reperfusion of ischemic intestine results in acute liver dysfunction characterized by hepatocellular enzyme release into plasma, reduction in bile flow rate, and neutrophil sequestration within the liver. The pathophysiology underlying this acute hepatic injury is unknown. This study was undertaken to determine whether oxidants are associated with the hepatic injury and to determine the relativ...
متن کاملProtective effects of fluvoxamine against ischemia/reperfusion injury in isolated, perfused guinea-pig hearts.
Serotonin (5-hydroxytryptamine; 5-HT) is known to be activated during ischemia-reperfusion and triggers contractile dysfunction and pathological apoptosis. Here, the beneficial effects of the selective serotonin reuptake inhibitor (SSRI) fluvoxamine was demonstrated on ischemia-reperfusion injury in guinea-pig hearts perfused using the Langendorff technique. The recovery (%) of left ventricular...
متن کاملCyclooxygenase inhibition aggravates ischemia-reperfusion injury in the perfused guinea pig heart: involvement of isoprostanes.
OBJECTIVES Postischemic contractile dysfunction in the heart may be due, in part, to isoprostanes, thought to accumulate during myocardial reperfusion. This study tested whether cyclooxygenase (COX) inhibitors increase the amount of isoprostanes and, consequently, lead to deterioration of postischemic heart function. BACKGROUND Isoprostanes are bioactive prostaglandin-like compounds that are ...
