Microcirculatory alterations after orthotopic pig-to-baboon heart transplantation.

abstract：BACKGROUND:Both the complement and the coagulation systems play important roles in the development of hyperacute or acute antibody-mediated xenograft rejection. Atrase B is a novel metalloproteinase isolated from the venom of Naja atra. In this study, we investigated the inhibitory effects of atrase B on complement act...
