| 摘 要： | 研究目的:补充大豆低聚肽对大鼠小肠上皮组织形态学和IEL的影响,观察大豆低聚肽对高强度运动后肠道粘膜屏障的保护作用.方法:雄性SD大鼠40只,被随机分为灌喂水安静(A)组、灌喂大豆低聚肽安静(B)组、灌喂水运动(C)组和灌喂大豆低聚肽运动(D)组.大鼠在适应性喂养及膳食平衡1周后,进行实验及指标测试.结果:高强度运动后,大鼠肠道粘膜机械屏障出现轻微损伤和IEL减少,而补充大豆低聚肽后,与C组比较,D组大鼠小肠粘膜厚度增高33.36%(P<0.05),小肠绒毛高度增高12.91%(P<0.05),小肠粘膜隐窝深度增加32.84%(P<0.05),IEL增加40.96%(P<0.05).结论:补充大豆低聚肽可改善高强度运动后小肠粘膜屏障功能. |

Effects of soy ol igopeptides supplemention on small intestinal mucosa barrier af ter high intensity exercise in rats |

| Abstract: | This paper was to study the effect s of soy oligopeptides supplementation on small intestinal mucosa barrier after high intensity exercise. Forty male SD rat s were randomly divided into four groups , Group A (no training and water supplemented) , Group B ( no training and soy oligopeptides supplemented) , Group C (training and water supplemented) , Group D (training and soy oligopeptides supplemented) . After one week meal adaption , small intestinal morphology were determined. It was shown that the small intestinal mucosa barrier were injured slightly after high intensity exercise. The mucosal thickness in Group D increased by 33. 36 % (p < 0. 05) than that of Group C. And the villous height increased by 12. 91 % ( p < 0. 05) , the crypt depth by 32. 84 % ( p < 0. 05) and IEL by 40. 96 % ( p < 0. 05) . It was proved that soy oligopeptides could im2 prove the the small intestinal mucosa barrier after high intensity exercise. |
