| 摘要: |
| [目的] 研究三七总皂苷微乳及溶液对1-甲基-4-苯基－1，2，3，6-四氢吡啶（MPTP）诱导的帕金森模型小鼠的治疗作用，为后期药代动力学及PK-PD研究奠定基础。[方法] 首先成功复制MPTP所致帕金森病的小鼠模型，连续5 d腹腔注射MPTP（30 mg/kg）。于造模起第3天给予三七总皂苷微乳及溶液（100 mg/kg）预处理MPTP所致的帕金森模型小鼠。于最后1次给药后进行行为学指标的测试，行为学实验结束后第2天各组小鼠断头取脑，用高效液相色谱-荧光检测器测定多巴胺（DA）含量。[结果] 在MPTP所致的帕金森模型小鼠中，其行为学障碍明显；三七总皂苷微乳及溶液治疗组，行为学障碍略有改善。与正常组比较，模型组DA含量显著降低（P<0.01），PNS微乳及溶液给药组DA含量显著升高（P<0.01），且两组间有统计学差异（P<0.01）。[结论] 三七总皂苷微乳对帕金森模型小鼠有明显的治疗作用，且三七总皂苷微乳组的效果优于溶液组。 |

| Abstract: |
| [Objective] To study the effective onset time of panax notoginseng saponin microemulsion on 1-methyl-4-phenyl-1, 2, 3, 6-tetrahydropyridine (MPTP)-induced Parkinson's mouse model, which is lay the fundation of the pharmacokinetics and PK-PD study.[Methods] First, MPTP-induced mouse model of Parkinson's disease was injected intraperitoneally with MPTP (30 mg/kg) for 5 days. On the third day after the model was given, Panax notoginseng microemulsion and solution (100 mg/kg) were given MPTP-induced Parkinson's model rats. After the last day of administration behavioral tests index, the next day after the behavioral experiments in each group decapitation brains were removed by HPLC-Determination of Dopamine in a fluorescence detector.[Results] Mice MPTP induced Parkinson in which significant behavioral disorders; Panax notoginseng saponins microemulsion and solution treatment group, a slight improvement in behavioral disorders. Compared with the normal group, the dopamine content in the model group was significantly lower (P<0.01), the dopamine content in the PNS microemulsion and solution administration group was significantly higher (P<0.01), and there was a significant difference between the two groups (P<0.01).[Conclusions] Panax notoginseng saponins microemulsion on the Parkinson model mice have a significant therapeutic effect, he effect of Panax notoginseng microemulsion group was better than that of solution group. |
