| 目的：探讨富含支链氨基酸的肠外营养对肝硬化大鼠肝部分切除术后肝脏自然杀伤细胞（NK 细胞）的影响。方法：20 只肝硬
化大鼠随机分为肝部分切除术后行8.5%Novamin 的肠外营养5 d 组10 只，肝部分切除术后行10%Hepa 的肠外营养5 d 组10
只。应用流式细胞仪测定大鼠肝脏NK 细胞的百分率；应用4 小时51Cr 释放法测定肝脏NK 细胞的杀伤活性。结果：与8.5%
Novamin 的肠外营养5 d 组比较，10%Hepa 的肠外营养5 d 组肝脏NK 细胞占全部淋巴细胞的百分比和肝脏NK 细胞杀伤活性
明显升高（P<0.05）。结论：富含支链氨基酸的肠外营养可以增加肝脏NK 细胞的百分率和肝脏NK 细胞的杀伤活性。 |

| Objective: To explore the effect of parenteral nutrition (PN) with branch-chain amino acids enrichment on the natural
killer cells in the liver after partial hepatectomy in rats with liver cirrhosis. Methods: Twenty rats with liver cirrhosis were randomly
divided into post-operation 8.5% Novamin PN 5 day group (n=10) and post-operation 10% Hepa PN 5 day group (n=10). Activity of NK
cells was measured by 4h 51Cr-release assay. The percentages of the NK cells in the livers was examined by flow cytometry. Results:
Compared with the 8.5% Novamine PN 5 day group, the percentages and the activity of NK cells in the livers were significantly increased
in the 10%Hepa PN 5 day group (P<0.05). Conclusion: Parenteral nutrition with branch-chain amino acids enrichment after partial
hepatectomy in rats with liver cirrhosis can ameliorate the percentages and the activity of NK cells in the livers. |
