摘要: 采用体外细胞培养方法,研究小鼠腹腔巨噬细胞在LPS刺激的情况下,从玉米蛋白粉中提取的叶黄素和玉米黄素对其生成NO的影响作用。噻唑蓝(MTT)法检测淋巴细胞及巨噬细胞增殖,比色分析检测巨噬细胞吞噬中性红的能力,生物法测定肿瘤坏死因子α(TNF-α)活性,Griess法测定NO含量。结果表明:叶黄素和玉米黄素对小鼠腹腔巨噬细胞的生长有一定的促进作用,当叶黄素、玉米黄素分别为5μmol/L和2.5μmol/L时对小鼠腹腔巨噬细胞产生NO表现为抑制作用,而当叶黄素的浓度在10~40μmol/L、玉米黄素的浓度在5~30μmol/L时巨噬细胞NO的生成水平表现为能显著提高正常小鼠腹腔巨噬细胞产生NO,且呈现剂量效应关系。叶黄素在20~50μmol/L,玉米黄素在10~40μmol/L的浓度范围内,能够促进巨噬细胞吞噬中性红的能力,并能诱导其分泌TNF-α。

Abstract: This study aimed at the relationship between lutein and zeaxanthin and NO released by macrophagesy,the mechanism of the immunomodulating activities of carotenoids. Lymphocyte and peritoneal macrophages proliferation in the presence or absence of lutein and zeaxanthin were detected with MTT assay in vitro. The percentage of phagocytosis of neutral red (NR) was detected with colorimetric assay. TNF-α in the culture supernatants were detected with biology assay. Nitric oxide (NO) production was examined by Griess reaction. The results showed: 1mg/L LPS used as stimulant,the NO release was inhibited by 5μ mol/L lutein and 2.5μmol/L zeaxanthin respectively,while NO release was enhanced when the concentration of lutein and zeaxanthin was eaceeded 10μmol/L and 5μmol/L respectively. The immunomolating function and antitumor activity of luteinand zeaxanthin may be associated with its effect on NO by macrophage in vitro.
