摘要: 目的 评价大黄素固相脂质纳米粒对大鼠帕金森模型的防治效果,为大黄素新制剂的研发提供参考。方法 采用乳化蒸发-低温固化法,应用单硬酯酸甘油酯、聚氧乙烯氢化蓖麻油RH40和聚山梨酯(吐温-80)(3∶1,w/w)将大黄素制成固相脂质纳米粒,通过口服给药,调查其对6羟基多巴胺(6OHDA)诱发的帕金森病模型大鼠的行为学、中脑组织中儿茶酚O甲基转移酶(COMT)和单胺氧化酶B(MAOB)含量的影响,评价其对帕金森症的防治作用。结果 大黄素固相脂质纳米粒在透视电镜下观察,外观呈圆球形,粒径介于40~100 nm;与生理盐水组帕金森模型大鼠比较,大黄素固相脂质纳米粒能够显著降低帕金森模型大鼠的中脑组织中的COMT和MAOB浓度,大黄素混悬液能显著降低帕金森模型大鼠中脑组织中MAOB浓度,但对COMT浓度无显著影响。结论 大黄素固相脂质纳米粒通过降低6OHDA诱发的帕金森模型大鼠脑内的COMT和MAOB水平发挥治疗帕金森症的作用,其效果优于混悬液。

Abstract: Objective  To evaluate therapeutic effect of emodin loaded solid lipid nanoparticles (EMOSLN) on  Parkinson model of  rats. Methods  EMOSLN were prepared by applying emulsion evaporationsolidification at low temperature method with glyceryl monostearate and cremophor RH40 as well as polysorbate 80(tween 80) (3:1,w/w). To observe the influence of EMOSLN in 6OHDA induced  the behavior  of  Parkinson model rats′, concentration of MAOB and COMT in middle brain following oral administration, therapeutic effect of EMOSLN on rats model of Parkinson disease.Results  EMOSLN was spherical in morphology and the diameter was in the range of 40100 nm. Compared with Parkinson disease model rats divided into normal saline group, rotating behavior of rats in EMOSLN group and emodin suspension group was improved. Concentrations of MAOB and COMT in middle brain of Parkinson disease model rats for EMOSLN group were significantly reduced,while MAOB concentration in middle brain of emodin suspension group reduced significantly but COMT concentration showed no significant difference compared to normal saline control group. Conclusion  EMOSLN showed effect on 6OHDA rat model of Parkinson disease by lowering concnentation of COMT and MAOB, and its therapeutic efficiency is better than that of emodin suspension.
