摘  要:【摘要】目的观察N(3,4-二甲氧基肉桂酰)邻氨基苯甲酸(3,4-DAA)对大鼠肝移植急性排斥反应的预防作用。方法以Wistar大鼠为供体,sD大鼠为受体,建立大鼠肝移植模型,随机分为4组。A组:对照组(n=22),B组:3,4-DAA400mg/(kg·d)组(n=22),C组:环孢素A(CsA)5mg/(kg·d)组(n=22)。D组:3,4-DAA400mg/(kg·d)+CsA5mg/(kg·d)组(n=22)。各组于手术当天起连续口服给药,分别于术后第3、5、7天处死受体,收集血液行肝功能检测并观察肝组织病理学变化。各组另随机选4只受体观察生存时间。结果(1)4组受体平均生存时间分别为(11.3±1.7)、(16.0±0.8)、(21.5±1.7)、(26.5±1.3)d,B组与A组比较生存时间延长,差异有统计学意义(P〈0.01);D组受体存活时间最长,与A、B、C3组比较,差异均有统计学意义(P〈0.01)。(2)B组大鼠术后各时间外周血谷丙转氨酶(ALT)、谷草转氨酶(AST)、总红胆素(T—BIL)值均低于A组(P〈0.05)。D组各时间点AIJT、AST、T-BIL值低于A、B、C组(P〈0.05)。(3)术后第7天肝脏排斥活动指数B组明显低于A组(P〈0.05),D组得分最低,与A、B、C组比较,差异有统计学意义(P〈0.05)。结论3,4-DAA能抑制大鼠肝移植术后急性排斥反应,与CsA合用具有协同作用。Objective To investigate the role of N-(3',4'-dimethoxycinnamonyl) anthranilic acid ( 3,4-DAA) in the prevention of acute rejection after orthotopic liver transplantation in rats. Methods The Wistar-SD rat orthotopic liver transplantation model was established and divided into four groups: group A (control group) , given normal saline (2 ml/d) orally after operation; group B, given 3,4-DAA at dose of 400 mg/(kg.d) ; group C, given cyclosporin A (CsA) at 5 mg/(kg·d) ; group D, given 3,4-DAA at 400 mg/( kg·d) and CsA at 5 rag/( kg· d). The samples ( peripheral blood and liver tissue) were obtained at 3rd, 5th and 7th day post-operation. Pathological study and serum test were performed on each sample. Four recipients were chosen randomly in each group for survival observation. Results ( 1 ) The average survival time of recipients in groups A, B, C and D was ( 11.3 ±1. 7 ) , ( 16.0 ± 0. 8 ), (21.5± 1.7 ) and (26. 5 ± 1.3 ) days, respectively. Recipients in group B survived longer than in group A (P 〈0. 01 ), and those in group D survived the longest in four groups ( P 〈 0. 01 ) ; (2) In group A, alanine aminotransferase (ALT), aspartate aminotransferase (AST) and total bilirubin (T-BIL) were dramatically increased, and the pathological examination showed severe acute rejection (AR) on the day 7. In group B, ALT, AST and T-BIL were decreased and the pathological examination showed lower RAI on the day 7 ( P 〈 O. 05 ). In group D, ALT, AST and T-BIL were decreased to the normal levels and AR was uncertainly detected on the day 7 (P 〈 O. 05 ). Conclusion 3,4-DAA exerts the anti-rejection effect after liver transplantation in rats.
