Major depressive disorder (MDD) is a severe disorder that causes enormous loss of quality of life, and among the factors underlying MDD is stress in maternal deprivation (MD). In addition, classic pharmacotherapy has presented severe adverse effects. Centella asiatica (C. asiatica) demonstrates a potential neuroprotective effect but has not yet been evaluated in MD models. This study aimed to evaluate the effect of C. asiatica extract and the active compound madecassic acid on possible depressive-like behavior, inflammation, and oxidative stress in the hippocampus and serum of young rats submitted to MD in the first days of life. Rats (after the first day of birth) were separated from the mother for 3 h a day for 10 days. When adults, these animals were divided into groups and submitted to treatment for 14 days. After subjecting the animals to protocols of locomotor activity in the open field and behavioral despair in the forced swimming test, researchers then euthanized the animals. The hippocampus and serum were collected and analyzed for the inflammatory cytokines and oxidative markers. The C. asiatica extract and active compound reversed or reduced depressive-like behaviors, inflammation in the hippocampus, and oxidative stress in serum and hippocampus. These results suggest that C. asiatica and madecassic acid have potential antidepressant action, at least partially, through anti-inflammatory and antioxidant profiles.
重度抑郁症(MDD)是一种严重的疾病,会导致生活质量的巨大损失,而导致 MDD 的因素之一是母体剥夺(MD)引起的压力。此外,经典的药物治疗已经表现出严重的不良反应。积雪草(C. asiatica)表现出潜在的神经保护作用,但尚未在 MD 模型中进行评估。本研究旨在评估积雪草提取物和活性化合物积雪草酸对生命早期第 1 天经历 MD 的幼鼠海马和血清中可能出现的抑郁样行为、炎症和氧化应激的影响。大鼠(出生后第 1 天)每天与母亲分离 3 小时,共 10 天。成年后,这些动物被分为几组,并接受 14 天的治疗。在对动物进行旷场运动活动方案和强迫游泳试验中的行为绝望方案后,研究人员对动物进行安乐死。收集海马体和血清并分析炎症细胞因子和氧化标志物。积雪草提取物和活性化合物可逆转或减轻抑郁样行为、海马体中的炎症以及血清和海马体中的氧化应激。这些结果表明,积雪草和积雪草酸至少部分通过抗炎和抗氧化作用具有潜在的抗抑郁作用。
