The current investigation aimed to scrutinize the neuro-protective effect of hyperforin on β‑amyloid peptide (Aβ) and HO induced injury in PC12 cells and colchicine induced Alzheimer's disease (AD). PC12 cells were treated with HO and (Aβ) in the presence of hyperforin. The cell viability was determined via suing the MTT assay; malondialdehyde (MDA) and lactate dehydrogenase (LDH) levels were also scrutinized. Colchicine induced the destruction of memory and learning which was exhibited in neurobehavioral theory (passive avoidance and Morris water maze) connected with reduced activity of acetylcholinesterase (AChE). Anti‑oxidant and inflammatory parameters also estimated. Hyperforin dose dependently increased the cell viability and reduced the MDA and LDH release via PC12 cell injured with HO and (Aβ). Hyperforin treatment lead to a considerable enhance in TLT in the retention trials as comparisian to acquisition trial suggesting as boosting memory and learning in rats. Hyperforin treatments significantly increase the AChE and reduced the superoxide dismutase, glutathione, MDA, protein carbonyl, glutathione peroxdiase, catalase, NF‑kB and IL‑1β at dose dependent manner. In summary, the model of HO and (Aβ) induced PC12 cell injury was successfully developed and dose dependently treatment of hypoforin showed the neuroprotective effect against the HO and (Aβ) induced cell damage. These finding clearly exhibited that hyperforin reverted the colchicine induced neuro‑chemical and behavioural alteration via potent anti‑inflammatory and anti‑oxidant activity.
当前的研究旨在探究贯叶连翘素对β-淀粉样肽(Aβ)和羟基自由基(HO)诱导的PC12细胞损伤以及秋水仙碱诱导的阿尔茨海默病(AD)的神经保护作用。在贯叶连翘素存在的情况下,用HO和(Aβ)处理PC12细胞。通过MTT法测定细胞活力;还检测了丙二醛(MDA)和乳酸脱氢酶(LDH)水平。秋水仙碱诱导记忆和学习能力的破坏,这在神经行为学实验(被动回避和莫里斯水迷宫)中表现出来,同时伴随着乙酰胆碱酯酶(AChE)活性的降低。还评估了抗氧化和炎症参数。贯叶连翘素剂量依赖性地增加细胞活力,并减少HO和(Aβ)损伤的PC12细胞中MDA和LDH的释放。与获取试验相比,贯叶连翘素治疗导致在保留试验中被动回避潜伏期显著延长,表明对大鼠记忆和学习有促进作用。贯叶连翘素治疗以剂量依赖性方式显著增加AChE,并降低超氧化物歧化酶、谷胱甘肽、MDA、蛋白质羰基、谷胱甘肽过氧化物酶、过氧化氢酶、核因子κB和白细胞介素-1β。总之,成功建立了HO和(Aβ)诱导的PC12细胞损伤模型,贯叶连翘素的剂量依赖性治疗显示出对HO和(Aβ)诱导的细胞损伤的神经保护作用。这些发现清楚地表明,贯叶连翘素通过强大的抗炎和抗氧化活性逆转了秋水仙碱诱导的神经化学和行为改变。
