摘要: 本试验旨在研究布鲁氏菌侵染小鼠巨噬细胞过程中一氧化氮(NO)对布鲁氏菌的抑制作用,以及NO和非对称性二甲基精氨酸(ADMA)的相互作用关系。以布鲁氏菌标准疫苗株M5侵染小鼠巨噬细胞,采用Griess试剂法和酶联免疫吸附法(ELISA)测定细胞内外NO含量和ADMA水平,并对各个侵染时间段进行CFU计数。结果显示,被布鲁氏菌侵染后巨噬细胞的NO含量呈上升趋势,且胞外含量显著高于胞内(P<0.05),与对照组相比均差异显著(P<0.05);而巨噬细胞的ADMA含量随着侵染时间的增加与NO含量呈负相关,与对照组相比均差异极显著(P<0.01)。结合CFU计数结果,表明NO对布鲁氏菌的抑制作用只发生在侵染前期(12 h前),在侵染后期(12 h后)NO对布鲁氏菌的生长并未起到抑制作用,而ADMA在布鲁氏菌侵染小鼠巨噬细胞过程中对NO的生成有一定的抑制作用。

Abstract: This experiment was aimed to study the inhibition effects of nitric oxide (NO) on Brucella in the process of Brucella infecting mice macrophage, and the interaction relations between NO and asymmetry dimethylarginine (ADMA). Brucella vaccine strain M5 was used to infect mice macrophags, then NO production and ADMA levels were determined by the Griess reagent method and ELISA. CFU were counted for each infection period. Results suggest that the NO production of macrophages rose when they were infected by Brucella, and the extracellular release quantity was significanty higher than the intracellular (P<0.05). Compared with the control group, the differences were significant (P<0.05). But the ADMA levels showed the opposite trend with NO content. There were extremely significant differences (P<0.01) compared with the control group. Combined with CFU count results, it showed that the inhibition effects of NO on Brucella only occurred at the early stage of the infection (the former 12 h), but not at the later period (the last 12 h). The ADMA had certain inhibitory effect on NO generated in the process of Brucella infecting mice macrophage.
