Ischemia-reperfusion (IR) injury is a major cause of organ dysfunction following lung transplantation. We have recently described increased apoptosis in transplanted human lungs after graft reperfusion. However, a direct correlation between ischemic time, cell death, and posttransplant lung function has not yet been demonstrated. We hypothesized that an(More)
Although lung transplantation is a widely applied therapeutic modality for end-stage pulmonary disease, the long-term survival following this procedure is limited by the development of bronchiolitis obliterans (BO). We investigated the role of RANTES, a C-C chemokine, in the evolution of fibrous airway obliteration (FAO) using a rat heterotopic tracheal(More)
BACKGROUND Transplant immunosuppression regimen facilitates successful adenovirus-mediated gene transfection and retransfection in the rat lung. Herein, we investigated the effect of this strategy on circulating cytokines and antiadenoviral immunoglobin G antibody. METHODS Male Lewis rats were transfected with 1 x 10(9) pfu/mL of E1-deleted Ad5CMVLacZ(More)
OBJECTIVES Cardiopulmonary bypass (CPB) induces systemic inflammatory response with neutrophil activation and subsequent lung dysfunction. Rolipram, a selective phosphodiesterase type 4 inhibitor, blocks the decrease in levels of cyclic adenosine monophosphate associated with neutrophil activation. Here, we tested the protective effect of rolipram on(More)
