Hesperidin (HSD) is a natural compound with antioxidant potential. On the other hand, chronic stress had been linked to impaired cognitive functions as it affects many neurotransmitters and brain regions such as the hippocampus. The current study was conducted to examine the effect of HSD on learning and memory after chronic mild stress. Albino Wistar rats were subjected to chronic mild stress with HSD administered as supplements. HSD was found to decrease hippocampal amyloid beta and malondialdehyde levels, in addition, to preserve cognitive functions together with preserving hippocampus histological architecture. In conclusion, the present study sheds the light on the potential of HSD to ameliorate the deleterious effects of chronic mild stress on cognitive functions through brain-derived neurotrophic factor enhancement and reduction in Aβ formation in addition to activation of the antioxidant pathway.
橙皮苷(HSD)是一种具有抗氧化潜力的天然化合物。另一方面,慢性应激会影响许多神经递质和大脑区域,如海马体,从而导致认知功能受损。本研究旨在探讨 HSD 对慢性轻度应激后学习和记忆的影响。用 HSD 作为补充剂对白化 Wistar 大鼠进行慢性轻度应激。结果发现,HSD 可降低海马淀粉样β和丙二醛水平,此外,还可保持认知功能,同时保持海马组织学结构。总之,本研究表明,HSD 通过增强脑源性神经营养因子和减少 Aβ形成以及激活抗氧化途径,有可能改善慢性轻度应激对认知功能的有害影响。
