【摘要】 帕金森病(PD)是目前较为公认的一种难治的、缓慢进展的原因不明的脑病,尚没有十分满意的治疗方法。本文用熄风定颤胶囊灌胃给药的方法对PD模型大鼠进行了治疗,观察熄风定颤胶囊对PD模型大鼠行为学的影响;并测定熄风定颤胶囊对PD模型大鼠纹状体丙二醛(MDA)、超氧化物歧化酶(SOD)、谷光甘肽(GSH)、谷胱甘肽过氧化物酶(GSH-PX)含量的影响;观测熄风定颤胶囊对PD模型大鼠黑质酪氨酸羟化酶(TH)的影响。本实验将6-羟基多巴胺(6-OHDA)注入大鼠纹状体制备PD模型大鼠,设计并成功地对PD模型大鼠进行了熄风定颤胶囊灌胃给药治疗,发现给药后PD模型大鼠的行为学有了显著改善(p<0.01)。同时,纹状体丙二醛(MDA)含量下降,而谷胱甘肽(GSH)、谷胱甘肽过氧化物酶(GSH-PX)含量升高,说明中药熄风定颤胶囊可以增强PD模型大鼠的抗氧化应激能力,从而减少氧化应激反应所致的DA能神经元损伤。组织形态学检测发现,酪氨酸羟化酶(TH)阳性细胞增加,证实了给予PD模型大鼠熄风定颤胶囊,增加了TH的阳性表达,从而减轻PD型大鼠的旋转行为。本实验不但证明了中药熄风定颤胶囊治疗PD的方法是可行的,而且是行之有效的;同时揭示了熄风定颤胶囊治疗PD模型大鼠的作用机制,从而为中药治疗PD奠定了理论与实验基础,为PD的治疗提供了一种新的思路和方法。

【Abstract】 It is accepted at present that Parkinson’s disease(PD) is an Idiopathic encephalopathy to be slowly progressive and intractable, and has no satisfying methods to treat yet.This paper describes and discusses a method to cure the PD-model white rat by giving the TCM of Xi-feng-ding-chan capsule and its influence to rat behavior, relevant bio-chemical criterion and histomorphology.In this experiment, author prepares a PD-model white rat by injecting the 6-OHDA into the rat’s caudate putamen(CPu), and succeeds in designing and giving the TCM of Xi-feng-ding-chan capsule to the rats. As a result, rat not only survival but also remarkable improvement(p<0.01)in behavior after being given the TCM of Xi-feng-ding-chan capsule. At same time, MDA content decrease, the content of GSH and GSH-PX increase, so the TCM of Xi-feng-ding-chan capsule can improve anti-oxygenstress ability of PD-model white rat, and abate lethal damage to dopaminergic neurons bringing out by anti-oxygen stress.Histomorphology detection suggests that TH-positive cells increase after TCM treatment, and that demonstrate that TCM of Xi-feng-ding-chan capsule can increase the expression of TH-positive cells, and thereby inhibit the rat rotation behaviour.This experiment proves the TCM of Xi-feng-ding-chan capsule not only feasible but also valid; at one time, it make clear the function mechanism of this kind of TCM, and establishes a theoretical and experimental basis for curing PD by the TCM of Xi-feng-ding-chan capsule, and provides a new idea and method.
