Abstract:
Objective To study the early functional change of sinusoid endothelial cell after liver transplantation in rat, and to investigate the endothelia protective effect of prostaglandin E_1(PGE_1). Methods Rat orthotopic liver transplantation model was performed in "two-cuff method", grouped as follows: group A served as normal rat blank control, group B as operative control with normal donor, group C as experimental control with shock donor, and group D as experimental group with shock donor and PGE_1 administration ( n =8 in each group). Transplanted groups (referring to recipients without specific definition) were sacrificed 6 h after operation for blood taken to detect serum liver enzymes (ALT, LDH), malondialdehyde (MDA), nitric oxide (NO) and plasm endothelin (ET). Liver tissue was resected at the same time for standard pathologic examination. Comparison of the difference the results was made between groups. Results Cold preservation time and anhepatic phase were similar in each group, (2?0.5) h and (15?3) min respectively. All survived 6 h after transplantation (8/8) in group B and D with a survival rate of 100%, only 5 survived 6 h after transplantation in group C (5/8) with a survival rate of 62.5%. Comparing with group C, blood ALT, LDH, MDA, ET decreased and NO increased significantly in group D ( P
