Obesity is one of the major factors to increase various disorders like diabetes. The present paper emphasizes study related to the antiobesity effect of Phalaris canariensis seeds hexane extract (Al-H) in high-fat diet- (HFD-) induced obese CD1 mice and in streptozotocin-induced mild diabetic (MD) and severely diabetic (SD) mice.AL-H was orally administered to MD and SD mice at a dose of 400 mg/kg once a day for 30 days, and a set of biochemical parameters were studied: glucose, cholesterol, triglycerides, lipid peroxidation, liver and muscle glycogen, ALP, SGOT, SGPT, glucose-6-phosphatase, glucokinase, hexokinase, SOD, CAT, GSH, GPX activities, and the effect on insulin level. HS-H significantly reduced the intake of food and water and body weight loss as well as levels of blood glucose, serum cholesterol, triglyceride, lipoprotein, oxidative stress, showed a protective hepatic effect, and increased HDL-cholesterol, serum insulin in diabetic mice. The mice fed on the high-fat diet and treated with AL-H showed inhibitory activity on the lipid metabolism decreasing body weight and weight of the liver and visceral adipose tissues and cholesterol and triglycerides in the liver. We conclude that AL-H can efficiently reduce serum glucose and inhibit insulin resistance, lipid abnormalities, and oxidative stress in MD and SD mice. Our results demonstrate an antiobesity effect reducing lipid droplet accumulation in the liver, indicating that its therapeutic properties may be due to the interaction plant components soluble in the hexane extract, with any of the multiple targets involved in obesity and diabetes pathogenesis.
肥胖是导致多种疾病(如糖尿病)的主要因素之一。本研究论文强调了对大麦草种子正己烷提取物(Al-H)在高脂饮食(HFD)诱导的肥胖 CD1 小鼠和链脲佐菌素诱导的轻度糖尿病(MD)和重度糖尿病(SD)小鼠中的抗肥胖作用的研究。AL-H 以 400mg/kg 的剂量每天口服一次,共 30 天,用于 MD 和 SD 小鼠,研究了一组生化参数:葡萄糖、胆固醇、甘油三酯、脂质过氧化、肝和肌肉糖原、碱性磷酸酶(ALP)、天门冬氨酸氨基转移酶(SGOT)、丙氨酸氨基转移酶(SGPT)、葡萄糖-6-磷酸酶、葡萄糖激酶、己糖激酶、超氧化物歧化酶(SOD)、过氧化氢酶(CAT)、谷胱甘肽(GSH)、谷胱甘肽过氧化物酶(GPX)活性以及对胰岛素水平的影响。HS-H 显著降低了糖尿病小鼠的食物和水摄入量以及体重减轻、血糖、血清胆固醇、甘油三酯、脂蛋白、氧化应激水平,对肝脏具有保护作用,并增加了 HDL-胆固醇、血清胰岛素。在高脂肪饮食喂养并接受 AL-H 治疗的小鼠中,AL-H 对脂质代谢具有抑制活性,可降低体重、肝脏和内脏脂肪组织重量以及肝脏胆固醇和甘油三酯。我们得出结论,AL-H 可有效降低血清葡萄糖并抑制 MD 和 SD 小鼠的胰岛素抵抗、脂质异常和氧化应激。我们的结果表明,AL-H 具有抗肥胖作用,可减少肝脏中脂质滴的积累,这表明其治疗特性可能是由于正己烷提取物中可溶植物成分与肥胖和糖尿病发病机制中涉及的多个靶标相互作用所致。
