摘要: 本研究通过高糖高脂饮食(high-fat and high-sugar diet,HSHF)建立SD大鼠代谢综合征模型,旨在探究葡萄籽原花青素对代谢综合征大鼠的体质量、血糖浓度、胰岛素敏感性、血清脂质水平和炎症的干预作用。结果表明,与正常对照组相比,24?周后,喂食HSHF的大鼠出现腹部肥胖、葡萄糖耐量降低、动脉粥样硬化性血脂紊乱、肝脏脂肪沉积。葡萄籽原花青素(20、40、80?mg/kg mb)干预大鼠8?周后,空腹血糖、血清甘油三酯、总胆固醇、低密度脂蛋白胆固醇、炎症因子白细胞介素-6和肿瘤坏死因子-α水平均显著降低,高密度脂蛋白胆固醇水平显著升高。苏木精-伊红切片分析结果表明,葡萄籽原花青素能够减小脂肪组织细胞脂滴面积,减轻了肝脏脂肪沉积。葡萄籽原花青素降低代谢综合征大鼠的体质量,改善大鼠血糖和脂代谢紊乱,以及降低血清炎症因子水平,因此有望作为潜在的调节代谢综合征的天然活性产物。

Abstract: In this study, an SD rat model of metabolic syndrome was established by feeding a high-fat and high-sugar diet (HSHF), aiming to explore the effects of grape seed proanthocyanin extract (GSPE) on body mass, blood glucose, insulin sensitivity, serum lipids and inflammation in rats with metabolic syndrome (MetS). The results showed that the HSHF diet-fed rats developed abdominal obesity, impaired glucose tolerance, atherosclerotic dyslipidemia, liver fat deposition and other phenotypes after 24 weeks compared with the control group; and after GSPE (20, 40 and 80 mg/kg mb) intervention in rats for 8 weeks, fasting blood glucose, serum triglyceride, total cholesterol, low-density lipoprotein cholesterol, and the inflammatory cytokines interleukin-6 and tumor necrosis factor-α were significantly reduced, while high-density lipoprotein cholesterol levels were significantly elevated. In addition, hematoxylin-eosin staining analysis showed that GSPE reduced adipose cell size and liver fat deposition. Therefore, GSPE can reduce the body mass of MetS rats, improve blood sugar and lipid metabolism disorders, and reduce serum inflammatory cytokine levels and are expected to be a potential bioactive product for regulating metabolic syndrome.
