INTRODUCTION: Parkinsonism is a neurodegenerative disorder. Pomegranate (POM) has been previously shown to have a dopaminergic neuroprotective effect against parkinsonism. OBJECTIVE: The aim of the current study is to investigate the possible effect of POM in combination with each of vinpocetine, propolis, or cocoa in the treatment of parkinsonism disease even without being given as adjuvant to L-dopa . METHODS: Rats were divided into seven groups, one normal and six RT model groups. One of the RT groups (2.5 mg/kg/48 h/10 doses sc), for 20 days served as non-treated parkinsonism model, whereas the others were treated with either L-dopa (10 mg/kg, p.o./day) or with POM (150 mg/kg, p.o./day) together with each of the following; vinpocetine (VIN) (20 mg/kg, p.o./day), propolis (300 mg/kg, p.o./day), cocoa (24 mg/kg, p.o./day). Motor and cognitive performances were examined using four tests (catalepsy, swimming, Y-maze, open field). Striatal dopamine, norepinephrine, serotonin, GABA, glutamate, acetylcholinesterase, , BDNF levels were assessed as well as MDA, SOD, TAC, IL-1β, TNF-α, iNOs, and caspase-3. Also, histopathological examinations of different brain regions were determined. RESULTS: Treatment with L-dopa alone or with all POM combination groups alleviated the deficits in locomotor activities, cognition, neurotransmitter levels, acetylcholinesterase activity, oxidative stress, and inflammatory markers as well as caspase-3 expression induced by RT. CONCLUSION: Combinations of POM with each of VIN, propolis, or cocoa have a promising disease-modifying antiparkinsonian therapy even without being given as an adjuvant to L-dopa.
引言:帕金森症是一种神经退行性疾病。先前已证明石榴(POM)对帕金森症具有多巴胺能神经保护作用。 目的:本研究的目的是探究石榴与长春西汀、蜂胶或可可分别联合使用在治疗帕金森症方面的可能效果,即使不与左旋多巴联合使用作为辅助治疗。 方法:将大鼠分为七组,一组为正常组,六组为利血平(RT)模型组。其中一组RT组(2.5毫克/千克/48小时/10剂,皮下注射),连续20天作为未治疗的帕金森症模型,而其他组则分别用左旋多巴(10毫克/千克,口服/天)或石榴(150毫克/千克,口服/天)与以下物质联合使用:长春西汀(VIN)(20毫克/千克,口服/天)、蜂胶(300毫克/千克,口服/天)、可可(24毫克/千克,口服/天)。使用四项测试(僵住症、游泳、Y迷宫、旷场试验)来检测运动和认知能力。评估纹状体中的多巴胺、去甲肾上腺素、血清素、γ-氨基丁酸(GABA)、谷氨酸、乙酰胆碱酯酶、脑源性神经营养因子(BDNF)水平,以及丙二醛(MDA)、超氧化物歧化酶(SOD)、总抗氧化能力(TAC)、白细胞介素-1β(IL-1β)、肿瘤坏死因子-α(TNF-α)、诱导型一氧化氮合酶(iNOs)和半胱天冬酶-3(caspase-3)。此外,还对不同脑区进行了组织病理学检查。 结果:单独使用左旋多巴或所有石榴联合用药组的治疗均减轻了由利血平诱导的运动活动、认知、神经递质水平、乙酰胆碱酯酶活性、氧化应激和炎症标志物以及半胱天冬酶-3表达方面的缺陷。 结论:石榴与长春西汀、蜂胶或可可分别联合使用,即使不与左旋多巴联合作为辅助治疗,也具有前景广阔的疾病修饰性抗帕金森病治疗作用。
