门冬氨酸鸟氨酸对肝切除术后肝功能保护作用的研究

Objective To investigate the protective effects of L-Ornithine-L-Aspartate on liver function in patients after liver resection. Methods Eighty-two patients undergoing liver resection were randomly divided into study group and control group. Control group was treated with conventional therapy and study group had conventional therapy plus L-Ornithine-L-Aspartate for injection intravenously from the first day before operation to the seven day after operation. The fasting alanine aminotransferase (ALT), aspartate aminotransferase ( AST ), γ-glutamyl transpeptadase(GGT), total bilirubin(TB), direct bilirubin(DB) and blood ammonia(BA) levels were determined before operation and on days 1, 3 and 7 after operation. Results On days 1, 3 and 7 after operation, ALT and AST levels in the study group ALT: ( 115.58 ± 69. 20), (81. 36 ± 14. 55 ), ( 61.24 ± 11. 32) U/L; AST: ( 127.29 ±33.61 ), (95.26 ± 16.83 ), (55.16 ± 14.83 )U/L] were significantly lower than those in the control groupALT:(175.27 ±68.35), (97.37 ±34.24), (78.28 ± 19. 73) U/L;AST: (152. 29 ±31.65), (115.28 ±35.24),(82.49 ± 28.18) U/L] (P ＜ 0.05 ). In the study group of the porta blocked over 15 min, levels of AST, ALT were obviously lower than that of the control group( P ＜ 0. 05 ). Conclusions L-Ornithine-L-Aspartate for injection can alleviate the hepatic dysfunction after hepatectomy, especially in the long time of porta blocked and has protective advantage for liver function.
