中文摘要：

目的探讨朱砂和雄黄在安宫牛黄丸(AGNH)配方中对脂多糖(LPS)介导的神经损伤的保护作用及机制。方法制备大鼠中脑原代神经元-神经胶质细胞联合培养模型。实验分为正常对照组、LPS 10μg.L-1模型组、LPS +朱砂(4和40 mg.L-1)组、LPS +雄黄(4和40 mg.L-1)组和LPS +AGNH(40和400mg.L-1)组。药物与细胞作用30 min后加入LPS;7 d后进行实验指标检测。采用免疫组织化学染色法检测酪氨酸羟化酶阳性的细胞数量和形态学变化以及小神经胶质细胞的激活情况,实时RT-PCR检测细胞中肿瘤坏死因子α(TNF-α)mRNA和诱导型一氧化氮合酶(iNOS)mRNA表达水平,酶联免疫吸附试验(ELISA)与Griess试剂分别检测细胞培养上清液中TNF-α和一氧化氮(NO)的含量。结果与正常对照组比较,LPS10μg.L-1作用于细胞,多巴胺能神经元的数量明显下降了40%(P<0.05);LPS显著诱导小神经胶质细胞的激活,TNF-αmRNA和iNOS mRNA的表达分别增加了9倍和2倍(P<0.05),同时神经元-胶质细胞联合培养上清液中TNF-α和NO的含量分别增加了20倍...

英文摘要：

OBJECTIVE To investigate the role of cinnabar and realgar in Angong Niuhuang Wan (AGNH)-produced neuroprotection against lipopolysaccharide (LPS)-mediated neuronal damage and further explore the corresponding mechanisms.METHODS Primary rat midbrain neuron-glia cultures were used as an in vitro model to investigate effects of AGNH on LPS-mediated degeneration of dopamine (DA) neurons.The experiment was divided into normal control group,LPS model group,LPS+cinnabar (4 and 40 mg·L-1) groups,LPS+realgar (4 and ...
