Cobra venom factor was given to prevent hyperacute rejection and FK506 was given to prevent cellular rejection. The xenograft recipients were killed and cardiac xenografts harvested 4, 8, 12, 16, 24 hours after transplantation. Histologic examination was used to demostrate the degree of rejection and coagulation while revers transcriptase-polymerase chain reaction was used to detect the expression of tissue factor mRNA, and the guinea pigs hearts, harvested but not transplanted, were studied as controls in all samples.
