The effectiveness of the T6 process (surfactant treatment) to decrease calcification of porcine aortic valvular (PAV) and bovine pericardial (BPV) bioprostheses was investigated. Morphologic and biochemical studies were made of standard and T6-treated PAVs and BPVs that had been implanted for a mean of 20 weeks in the tricuspid position in young sheep.(More)
We studied proliferation and interleukin 2 production by B6 mouse spleen cells in response to stimulation by irradiated cynomolgus monkey spleen cells and compared the results with responses against whole MHC-disparate allogeneic controls (BALB/c). We found that (a) primary xenogeneic helper responses were absent, whereas primary allogeneic responses were(More)
The purpose of the present study was to identify which of the several possible defects in cell-surface-molecule interactions are responsible for diminished mouse helper T cell responses to xenoantigens. We measured primary mouse anti-monkey, anti-pig, and anti-human proliferation in vitro in experimental systems in which potential defects were partially(More)
We studied the follow-up status of 56 patients after operation for fixed left ventricular outflow tract obstruction (LVOTO), 42 with discrete LVOTO consisting of an obstructing membranous ring in the left ventricular outflow tract (LVOT) and 14 with tunnel (diffuse) LVOTO. Forty-one of the 56 patients were available for long-term follow-up. Patients with(More)
Studies of postmyeloablative immune reconstitution have been reported for allogeneic bone marrow transplantation and also for non-T cell-depleted autologous/syngeneic BMT. However, there is a paucity of information regarding immune recovery following T cell-depleted autologous/syngeneic BMT. We have developed a primate transplantation tolerance model in(More)
B10.PD1 mice are transgenic animals expressing a class I MHC antigen of pigs. B10.PD1 skin graft survival on B6 mice was prolonged by anti-CD4 antibody treatment in vivo but not by anti-CD8 treatment. These results suggest: (1) that the defect in cell-mediated recognition of xenografts involves an interaction with the xeno-MHC antigens themselves and not(More)
INTRODUCTION Endotracheal intubation is one of the most invasive stimuli in anesthesia and it's often accompanied by a hemodynamic pressor response. The purpose of this study was to investigate the efficacy of a single pre-induction 2 µg/kg bolus injection of fentanyl followed by two puffs of nitroglycerin sub lingual spray (400 µg /spray) with a(More)
Our interest in MHC-mismatched allogeneic bone marrow transplantation (BMT) in the rhesus monkey prompted us to investigate restriction fragment length polymorphism analysis as a means for detecting lymphohematopoietic chimerism in the primate. A human MHC (HLA) class II DR beta gene cDNA probe was tested on rhesus peripheral blood mononuclear cell DNA(More)
