        摘  要   目的:评价安儿宁颗粒的体外抗菌、抗炎和免疫增强活性。方法:采用微量稀释法检测安儿宁颗粒(1.562 5~100 mg/mL)
        对10种临床常见致病菌的抑制作用并计算其最低抑菌浓度(MIC);以RAW 264.7细胞(单核巨噬细胞)为对象,采用脂多糖(LPS)
        诱导建立细胞炎症模型,以MTT法考察安儿宁颗粒(0.312 5~20 mg/mL)对细胞增殖及其释放一氧化氮(NO)的影响;以BALB/c
        小鼠脾脏淋巴细胞为对象,以MTT法考察安儿宁颗粒(0.312 5~20 mg/mL)对细胞增殖的影响。结果:安儿宁颗粒对表皮葡萄球
        菌和肺炎链球菌的 MIC 均为 6.25 mg/mL,对变形杆菌、肺炎克雷伯菌、枯草芽孢杆菌和大肠埃希菌(标准菌株)的 MIC 均为 12.5
        mg/mL,对铜绿假单胞菌、粪肠球菌、蜡样芽孢杆菌的MIC均为25 mg/mL,对大肠埃希菌(临床分离菌株)、伤寒沙门菌的MIC均为
        50 mg/mL。与LPS模型组比较,安儿宁颗粒在0.312 5~1.25 mg/mL的剂量下能显著降低LPS诱导的RAW 264.7细胞中NO的释
        放(P<0.05);与空白对照组比较,安儿宁颗粒在试验剂量下对RAW 264.7细胞和小鼠脾脏淋巴细胞增殖无干扰或有促增殖趋势,
        其在0.625、0.312 5 mg/mL剂量下能显著促进淋巴细胞增殖(P<0.05)。结论:安儿宁颗粒在体外对临床常见的革兰氏阳性和革兰
        氏阴性致病菌均有一定的抑制作用,并具有抗炎和免疫增强作用。

        ABSTRACT    OBJECTIVE:To evaluate the in vitro antibacterial,anti-inflammatory and immunopotentiating activity of An’
        erning granules. METHODS:Micro-dilution method was used to determine the minimum inhibitory concentration(MIC)of An’
        erning granules (1.562 5-100 mg/mL) on 10 kinds of common pathogenic bacteria. Using RAW 264.7 cells (mono-nuclear
        macrophage)as objects,LPS was used to replicate inflammation model. MTT assay was used to investigate the effects of An’
        erning granules(0.312 5-20 mg/mL)on proliferation and the release of NO of macrophage. Using spleen lymphocyte of BALB/c
        mice as objects,MTT assay was used to investigate the effects of An’erning granules (0.312 5-20 mg/mL) on lymphocyte
        proliferation. RESULTS:MIC of An’erning granules to Epidermis staphylococcus and Streptococcus pneumoniae was 6.25 mg/mL;
        MIC of An’erning granules to Proteus vulgaris,Klebsiella pneumoniae,Bacillus subtilis and Escherichia coli(standard strain)
        were 12.5 mg/mL;MIC of An’erning granules to Pseudomonas aeruginosa,Enterococcus faecalis and Bacillus cereus were 25
        mg/mL;MIC of An’erning granules to E. coli(clinical isolates)and Salmonella typhia were 50 mg/mL. Compared with LPS
        model group,An’erning granules could significantly reduce the LPS-induced release of NO in RAW 264.7 cells at the dose of
        0.312 5-1.25 mg/mL(P<0.05). Compared with blank control group,An’erning granule had no interference on the proliferation of
        RAW 264.7 cells and spleen lymphocytes of mice or had a tendency to promote proliferation. It could significantly promote
        lymphocyte proliferation at doses of 0.625 and 0.312 5 mg/mL(P<0.05). CONCLUSIONS:An’erning granules not only have
        certain in vitro inhibitory effects on clinical common Gram-positive and Gram-negative pathogenic bacteria,but also have
        anti-inflammatory and immunization enhancement effects.
