摘  要:目的观察新型组合式生物人工肝治疗急性肝功能衰竭犬的作用。方法D-氨基半乳糖给药构建犬急性肝功能衰竭模型,实验分组:组合式生物人工肝治疗组(n=8);生物人工肝治疗组(n=8);非生物人工肝治疗组(n=8);对照组(n=8)。观察和检测所有犬一般情况、生化指标及生存率,同时进行安全性评价。结果组合式生物人工肝其有良好的解毒及合成功能。4组犬的生存率分别是87.5%、62.5%、50.O%、37.5%,仅组合式生物人工肝组与对照组之间差异有统计学意义(P〈0.05),其余各组差异均无统计学意义(P〉0.05)。结论组合式生物人工肝对治疗急性肝功能衰竭具有良好的疗效。Objective To evaluate the efficacy of a novel hybrid bioartificial liver based on multi- layer fiat-plate bioreactor in treatment of acute liver failure. Methods The animals were divided into the hybrid bioartificial liver (HBAL) treatment group ( n = 8 ), the bioartificial liver (BAL) treatment group ( n = 8 ) , the non-bioartificial liver (NBAL) treatment group ( n = 8 ) , and the control group ( n = 8). Bio- chemical parameters and survival time were determinedt. The levels of xenoantibodies ( IgG, IgM ) were determined by using enzyme linked immunosorbent assay (ELISA). The PERV mRNA expression in the plasma was detected by using reverse transcription-polymerase chain reaction (RT-PCR). Results Bio- chemical parameters were significantly decreased in all treatment groups. Analysis of survival curves showed that the 7-day survival rate was 37.5% (3/8) in the control group, 50. 0% (4/8) in the NBAL group, 62. 5% (5/8) in the BAL group and 87. 5% (7/8) in the HBAL group respectively. Survival time was significantly prolonged by HBAL treatment ( P 〈 0. 05 ). Conclusion The hybrid bioartificial liver showed a great efficiency in the treatment of acute liver failure.
