BACKGROUND The early inflammatory response induced following vascularized organ allotransplantation is mediated by adhesin-ligand interactions between blood leukocytes and allogeneic endothelial cells. In the present study, we focused on the role of allogeneic blood lymphocytes in early immune alterations following lung reperfusion. METHODS We developed(More)
Postoperative hepatic insufficiency is a rare cause of liver failure. Consequences of this usually predictable complication can be limited by appropriate preventive measures and careful postoperative management. This report reviews the current experimental and clinical literature with regard to postoperative hepatic insufficiency. L'insuffisance hépatique(More)
BACKGROUND In a model of mouse isolated lung, we have recently demonstrated that E-selectin is involved in the activation of endothelial cells induced by allogeneic blood perfusion. In the present study, we explored the signaling pathway of apoptosis induced by E-selectin triggering. METHODS Lungs were perfused for 3 hours with fresh blood in the absence(More)
OBJECTIVES Pulmonary vascular resistance decreases dramatically after pulmonary thromboendarterectomy and further improves in time. This may reflect the slow regression of postobstructive pulmonary vasculopathy. We hypothesized that postobstructive pulmonary vasculopathy may regress after reperfusion in a piglet model of chronic (5 weeks) left pulmonary(More)
BACKGROUND The advent of cardiac gene therapy in clinical practice requires a more efficient and safer myocardial gene delivery in large animals. A new approach to adenovirus-mediated intracoronary gene transfer in the piglet, using a heterotopic heart transplantation model, was designed to maximize the duration of contact between the vector and the heart(More)
OBJECTIVE Increase in lung permeability is an inevitable consequence of pneumonectomy in relation to inflammatory injury and increased perfusion flow. We tested whether inhaled nitric oxide, a potent vasodilatator and anti-inflammatory agent, prevents postpneumonectomy edema in the first 24 hours after pneumonectomy in pigs. METHODS We assessed(More)
BACKGROUND The interaction between host lymphocytes and graft endothelial cells plays an important role in graft rejection. METHODS Using our model of isolated ventilated lung from female mouse perfused with fresh blood from either isogeneic or allogeneic male mouse for 3 hours without noticeable ischemia, we have investigated the kinetics of the early(More)
Acid extracted collegen is prepared from rat skin 48 hours after burning ; the material obtained is purified by salt precipitation and fractionnated by carboxymethylcellulose chromatography as described by Piez (3). Control samples are studied by a similar procedure. It can be concluded that after burning, rat skin collagen becomes insoluble ; the result(More)
BACKGROUND We hypothesized that gene transfer of vascular endothelial growth factor (VEGF) mediated by an adenovirus vector might induce pulmonary artery angiogenesis in a lamb model of pulmonary artery hypoplasia. METHODS Thirteen fetal lambs had left pulmonary artery banding at 106 days of gestation. Following birth, 3 groups were divided: VEGF group (n(More)
A fibrinogen variant was identified in a pregnant patient with disseminated intravascular coagulation and abruptio placentae. This dysfibrinogen was also found in four asymptomatic members of the patient's family. Coagulation studies showed prolongation of both the thrombin and reptilase times, and discrepancy was noted between the levels of plasma(More)
