补充Galactooligosaccharide (GOS) 有效地减少了老鼠的焦虑和压力反应. GOS使行为,免疫和肠道微生物群的障碍正常化,显示出与压力相关的疾病的治疗潜力.
科学领域:
- 神经科学是一个神经科学.
- 微生物学 微生物学
- 免疫学 免疫学 免疫学
背景情况:
- 杏仁体的中央核 (CeA) 调节恐惧和压力,过度活跃与焦虑症有关.
- 肠道微生物群的变化与焦虑,抑郁和PTSD的病理生理学有关.
- 了解肠-大脑轴对于开发新的治疗策略至关重要.
研究的目的:
- 为了研究银河氧糖 (GOS) 补充剂在缓解压力引起的障碍方面的疗效.
- 在大鼠模型中评估GOS对行为,血液学,免疫学和肠道微生物群参数的影响.
主要方法:
- 老鼠经历了长期电刺激CEA (Stim) 或假冒程序 (Sham).
- 刺激组要么没有补充剂,要么接受3周的GOS补充剂.
- 进行了行为测试 (动量计,升高加迷宫),血液计数,血细胞因子分析和肠道微生物群概况.
主要成果:
- 刺激诱导过活,增加焦虑,改变血细胞计数 (WBCs,LYMs,RBCs,PLTs),TNFα升高,IL-10降低,以及肠道失调.
- GOS补充剂使这些Stim诱导的干扰正常化,往往达到假的水平.
- GOS的效果与citalopram相似,WBCs/PLTs的正常化和IL-10诱导的优势更高.
结论:
- 在焦虑和与压力有关的疾病中,GOS显示出显著的治疗潜力.
- GOS补充剂可以作为PTSD,抑郁症和焦虑症的辅助治疗或预防措施.
- 用GOS准肠道微生物群为管理与压力相关的疾病提供了一个有希望的途径.

Drugs Acting on Autonomic Ganglia: Stimulants
Ganglionic stimulants activate NM nicotinic receptors in autonomic ganglia, falling into two categories: nicotine mimetics [e.g., lobeline, dimethylpiperazine, tetramethylammonium] and muscarinic receptor agonists [e.g., muscarine, methacholine]. The first category's action is rapid and blocked by nicotinic receptor antagonists, while the second category's action is delayed and blocked by atropine-like agents. Nicotine, an alkaloid, affects the heart rate by stimulating sympathetic or...
