Accumulation of reactive oxygen species (ROS) in response to excess alcohol exposure is a major cause of gut barrier disruption and lipopolysaccharide (LPS)-induced hepatic inflammation, as well as liver steatosis and apoptosis. This study was designed to investigate protective effects of the cricket , an edible insect recognized by the Korea Food and Drug Administration, against acute alcoholic liver damage in mice. Administration of extracts (GBE) attenuated alcohol-induced steatosis and apoptotic responses in the liver and intestinal permeability to bacterial endotoxin. These protective effects were associated with suppression of ROS-mediated oxidative stress in both the liver and small intestine. Furthermore, in vivo and in vitro studies revealed that GBE inhibits LPS-induced Kupffer cell activation and subsequent inflammatory signaling. Importantly, the protective effects of GBE were more potent than those of silymarin, a known therapeutic agent for alcoholic liver diseases.
活性氧 (ROS) 的积累是对过量酒精暴露的反应,是肠道屏障破坏和脂多糖 (LPS) 诱导的肝炎症以及肝脂肪变性和细胞凋亡的主要原因。本研究旨在探讨蟋蟀的保护作用,蟋蟀是韩国食品药品管理局认可的可食用昆虫,可防止小鼠急性酒精性肝损伤。提取物 (GBE) 的给药减轻了酒精引起的肝脂肪变性和肝凋亡反应,以及肠道对细菌内毒素的通透性。这些保护作用与抑制肝脏和小肠中 ROS 介导的氧化应激有关。此外,体内和体外研究表明,GBE 抑制 LPS 诱导的枯否细胞激活和随后的炎症信号。重要的是,GBE 的保护作用强于水飞蓟素,水飞蓟素是一种已知的治疗酒精性肝病的药物。
