自近两个世纪前第一次描述帕金森病(PD)以来,许多研究已经揭示了克服这种难治性神经退行性疾病的临床症状、病理和治疗方法。1-甲基-4-苯基-1,2,3,6-四氢吡啶(MPTP)和6-羟基多巴胺(6-OHDA)是引起帕金森病的神经毒素。从使用这些神经毒素的动物研究中,已经确定氧化应激是多巴胺能神经元细胞凋亡的主要原因和必要条件。在这里,我们描述了氧化应激引起不可逆细胞死亡的机制,并提出了一种利用氢分子治疗PD的新策略。在两种实验动物模型中,氢具有减少氧化损伤和改善黑质纹状体多巴胺能神经元通路丧失的能力。因此,我们强烈建议氢可能在预防或减少PD的发生和进展方面提供很大的优势。
Since the first description of Parkinson's disease (PD) nearly two centuries ago, a number of studies have revealed the clinical symptoms, pathology, and therapeutic approaches to overcome this intractable neurodegenerative disease. 1-methy-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) and 6-hydroxydopamine (6-OHDA) are neurotoxins which produce Parkinsonian pathology. From the animal studies using these neurotoxins, it has become well established that oxidative stress is a primary cause of, and essential for, cellular apoptosis in dopaminergic neurons. Here, we describe the mechanism whereby oxidative stress evokes irreversible cell death, and propose a novel therapeutic strategy for PD using molecular hydrogen. Hydrogen has an ability to reduce oxidative damage and ameliorate the loss of nigrostriatal dopaminergic neuronal pathway in two experimental animal models. Thus, it is strongly suggested that hydrogen might provide a great advantage to prevent or minimize the onset and progression of PD.
