概括
袖子胃切除术 (SG) 在肥胖大鼠中显著降低了林水平,改善了体重减轻,脂肪和新陈代谢. 胃缩 (GP) 对 ghrelin 或代谢改善没有表现出类似的效果.
科学领域:
- 腹部外科 腹部外科
- 代谢研究研究 代谢研究
- 内分泌学 在内分泌学.
背景情况:
- 袖子胃切除术 (SG) 和胃复合 (GP) 是减肥手术,可以减少胃的尺寸.
- 手术后观察到的改善不仅仅是由于热量限制.
- 饮食诱导的肥胖 (DIO) 老鼠模型被用来研究这些程序.
研究的目的:
- 在SG或GP后分析DIO大鼠的脂肪和代谢变化.
- 为了将这些变化与总格林及其异型相关联.
- 为了比较SG和GP对代谢参数和激素水平的影响.
主要方法:
- 191只雄性Wistar大鼠接受了假手术 (SO),SG或GP.
- 测量了脂肪,脂溶和循环中的 ghrelin 异型.
- 结果与正常或高脂肪饮食对照对照 (PF) 进行了比较.
主要成果:
- 与SO和PF相比,SG导致显著降低脱 ghrelin (DAG) 和总 ghrelin.
- SG老鼠的体重减轻,脂肪减少,以及改善葡萄糖/脂质代谢.

Hormonal Regulation
43.1K
Hormones regulate a significant portion of digestion through activation of the neuroendocrine system. The neuroendocrine system of digestion contains many different hormones all with multiple functions that are both, directly and indirectly, involved in digestion.

Regulation of Food Intake
166
Short-term regulation of food intake primarily involves neural signals from the gastrointestinal (GI) tract, blood nutrient levels, and GI tract hormones. Communication between the gut and brain via vagal nerve fibers plays a significant role in evaluating the contents of the gut. Clinical studies have shown that protein ingestion produces a more prolonged response in these nerve fibers compared to an equivalent amount of glucose. Additionally, the activation of stretch receptors caused by GI...

Glucagon-like Receptor Agonists
280
Incretins include glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP), which stimulate insulin secretion post-meals. In type 2 diabetes, GIP's efficacy is reduced, making GLP-1 a viable drug target. GIP originates from preproGIP.
GLP-1, when administered in high doses intravenously, triggers insulin secretion, inhibits glucagon release, slows gastric emptying, reduces food intake, and restores normal insulin secretion. However, its rapid inactivation by...
