Abstract:
Objective To study the role of the expression of P-selectin and intercellular adhesion molecule-1(ICAM-1) in hamster to rat concordant cardiac xenotransplantation.Methods Intra-(abdominal) cardiac transplantation was performed by using SD rats as recipients of Golden Syrian(hamster) hearts.The rats were divided into 4 groups randomly: group I(n=15),unmodified(recipients) were used as control; group II(n=15),splenectomy at day 0;group III(n=15),the rats were treated with cyclosporine A(CsA) 10 mg/kg every day from day 0;group IV(n=15),splenectomy in combined with CsA.The survival of hamster hearts was observed in each group.The xenograft was harvested at rejection and scheduled time in accordance with the experimental design,and analyzed for histology.The expression of P-selectin and ICAM-1 was detected by immunohistochemistry in xenograft after xenotransplantation.Results The mean survival time of the xenograft in group IV was 34.20?8.98 days,which was significantly longer in groups I,II and III (P
