黄酮

The mechanism might be elevated the HIF-la in histocyte through which accelerate the expression of EPO level, enhance the bodys ability of carrying and transporting oxygen and increase the activity of key enzymes in glycolysis in hypoxia mice, and elevated the ATP level to remission the energy metabolism in hypoxia mice.

马齿苋总黄酮能够提高小鼠抗缺氧能力，机制可能通过提高组织HIF-1α含量，促进EPO表达，增加了血红蛋白的合成和红细胞的数量，增强机体携运氧能力，同时促进了无氧酵解进行，缓解了缺氧小鼠的能量代谢障碍。

Methods The article applied the orthogonal design to find out the optimum proportion of the rutin, soybean isoflavone and curcumin. The free radical DPPH scaving ratio was used as evaluating standard of orthogonol design and the hominal liver cancer cell SMMU-7721 was used in MTT trial to evaluate the inhibitory ability of the compound. Results The optimum proportion of rutin-soybean isoflavone-curcumin 2:3:7 was achieved.

选取3种天然植物抗氧化物质芦丁、大豆异黄酮、姜黄素，利用正交试验设计选择合适配方，以自由基DPPH的清除率作为正交试验评价标准，并利用人肝肿瘤细胞SMMU-7721进行四甲基偶氮唑盐试验来考察配方体外试验对肿瘤细胞的抑制作用。

The dopamine release in vivo was monitored by fast cyclic voltammetry and the concentrations of DA and its metabolites dihydroxy-phenylacetic acid and homovanillic acid were determined by high performance liquid chromatography electrochemical detection in the process study. In addition, the effects of some traditional Chinese herbs and related marine drug on behavioral changes were also evaluated in order to provide some suggestive clue for rational drug design of anti-Parkinon's disease .

许多因素都参与PD的DA能神经元的死亡，所以，本研究在制备PD动物模型的基础上，应用国内率先引进的快速周期伏安法检测设备在体动态监测DA的释放，同时应用另一种电化学检测技术—高效液相色谱电化学检测法离体检测DA及其代谢产物二羟苯乙酸和高香草酸的含量，结合行为学测定及其它方法，研究了雌激素和铁在PD发病中的作用，以及一些药物，如吲哚醌、牛磺酸、铁离子螯合剂、胆囊收缩素（CCK-8）、乌鸡白凤丸有效成份、大豆异黄酮及海洋酸性寡糖HSH971，对DA能神经元的影响，从DA能神经递质角度对PD的发病机理提供进一步的实验依据，并为PD的预防和治疗提供新的干预措施。
