摘要 目的:通过建立大鼠肝卵圆细胞增殖肝再生模型,探讨维生素K2对大鼠肝再生模型部分肝切除术后肝再生过程中肝功能恢复的影响。方法:180只SD雄性大鼠随机分为6组,实验组5组:(1)2AAF+VLVK2/PH,(2)2AAF+LVK2/PH,(3)2AAF+MVK2/PH,(4)2AAF+HVK2/PH,(5)2AAF+VHVK2/PH;对照组:2AAF/PH。分别于术后第4、8、12、16、20天采血检测血清天门冬氨酸氨基转移酶(AST)、血清丙氨酸氨基转移酶(ALT)、白蛋白(ALB)的动态变化情况。结果:2AAF/PH组第4、8天ALT、AST与5组维生素K2不同剂量实验组相比较明显升高(P<0.01),而血清ALB含量在第4、8天与5组维生素K2不同剂量实验组相比较明显降低(P<0.05)。5组维生素K2不同剂量实验组中2AAF+MVK2/PH组第4、8天与2AAF+VLVK2/PH、2AAF+LVK2/PH相比较血清ALT、AST明显降低(P<0.01),而血清ALB含量在第4、8天相比较明显升高(P<0.01)。2AAF+MVK2/PH组与2AAF+HVK2/PH、2AAF+VHVK2/PH组比较,ALT、AST、ALB差异无统计学意义(P>0.05)。结论:维生素K2对大鼠肝再生模型术后肝功能恢复有明显的改善作用;当剂量低于20mg/kg时,肝功能恢复呈剂量依赖性。 Objective To investigate the positive effect of the vitamin K2 on recovery of liver function in the rat liver regeneration process. Methods 180 SD rats were randomly divided into six groups including five experimental groups: (1) 2AAF+VLVKyPH, (2) 2AAF+LVK2/PH, (3) 2AAF+MVK2/PH, (4) 2AAF+HVK2/ PH, (5) 2AAF+VHVKJPH, and control group: 2AAF/PH. The 70% partial hepatectomy (PH) were performed on the day 4, 8, 12, 16 and 20. The levels of ALT, AST, ALB in blood serum were examined. Results Rats in 2AAF/PH group had significantly higher ALT, AST and a markedly lower level of ALB than other experimental groups on the day 4, 8(P 〈 0.01, P 〈 0.01, P 〈 0.05). Rats in 2AAF+MVK2/PH had significantly lower ALT, AST and a more increased level of ALB than 2AAF+VLVK2/PH, 2AAF+LVKz/PH (P 〈 0.01., P 〈 0.01, P 〈 0.01 ). There was no significant difference among 2AAF+MVKi/PH, 2AAF+VLVKi/PH and 2AAF+LVK2/PH (P 〉 0.05). Conclusion Vitamin K2 can promote the recovery of rats liver function, and when dose were lower than 20 mg/ kg, the effect was dose dependent.
