文题释义:
肠道屏障功能:是指肠道将肠腔环境与机体内组织环境分隔开,防止肠道内致病性抗原、毒素以及致病微生物侵入的功能。肠道屏障主要由肠道正常菌群、黏液层、肠上皮细胞层和肠道免疫系统组成。
益生菌:在人体肠道中定植,并通过一系列代谢活动调节肠道微生态平衡,增强人体消化吸收、免疫、对机体肠道黏膜的保护作用、促进肠道上皮细胞增生、加强肠道紧密连接、增加黏液分泌、促进胃肠动力、增加结肠黏膜短链脂肪酸的产生和减少氨的释放等方面具有重要的意义。
摘要
背景:
长时间的力竭性运动应激引起机体不同组织器官免疫功能发生变化及益生菌干预引起机体机制尚不明确。
目的:通过力竭性运动和益生菌干预观察大鼠不同组织器官形态学变化和细胞膜的保护作用。
方法:40只SD雄性大鼠随机分为安静对照组(正常对照),运动对照组,安静给药组,运动给药组。运动对照组与运动给药组进行6周力竭训练,速度为19.3 m/min,坡度为5°,每天训练1次,6 d/周。安静给药组与运动给药组每日灌胃浓度为107CFU/mL益生菌溶液10.0 mL/(kg.d)。6周力竭训练结束后,通过光学显微镜下观察其病理组织学变化和测定大鼠肝、肠和胃组织Na+/K+-ATP酶、Ca2+/Mg2+-ATP酶、T-ATP酶的指标。
结果与结论:①力竭运动引起大鼠肝、胃和肠组织结构紊乱、肿胀和有炎症细胞浸润现象,各组织中Na+/K+-ATP酶、Ca2+/Mg2+-ATP酶、T-ATP酶的活性有所下降;②通过服用益生菌溶液后大鼠肝、胃和肠组织结构排列紧密、清晰、无明显的充血和水肿,但仍有少量的炎症细胞和轻微的溃疡,各组织中Na+/K+-ATP酶、Ca2+/Mg2+-ATP酶、T-ATP酶的活性增高;③结果表明,益生菌溶液能够保护长时间力竭运动引起肝、胃和肠组织结构的变化和增高各组织中Na+/K+-ATP酶、Ca2+/Mg2+-ATP酶、T-ATP酶的活性来保证细胞膜的完整性及流动性。

Abstract:

BACKGROUND: Changes in the immune function of different tissues after long-time exhaustive exercise stress and probiotics intervention are still unclear.
OBJECTIVE: To observe the morphological changes and cell membrane protective effects of different tissues and organs in rats after exhaustive exercise and probiotics intervention.
METHODS: Forty Sprague-Dawley male rats were randomly allocated into quiet control group, exercise control group, quiet administration group and exercise administration group. Rats in the exercise control and exercise administration groups underwent 6 weeks of exhaustive training, at a speed of 19.3 m/min, slope of 5o, once daily, 6 days weekly. Rats in the quiet administration and exercise administration groups were given 107 CFU/mL probiotics via gavage, 10.0 mL/(kg•d). The histopathological changes were observed under light microscope and Na+/K+-ATPase, Ca2+/Mg2+-ATPase and T-ATPase in the liver, intestine and stomach were tested after 6 weeks of training.
RESULTS AND CONCLUSION: After exhaustive exercise, the liver, stomach and intestinal tissue presented with structure disorders, swelling and inflammatory cell infiltration and an decrease in the activity of Na+/K+-ATPase, Ca2+/Mg2+-ATPase and T-ATPase. After probiotic solution administrated, the structure of liver, stomach and intestine arranged closely and clearly, with no obvious congestion and edema. However, there were a few inflammatory cells and slight ulcers, and the activities of Na+/K+-ATPase, Ca2+/Mg2+-ATPase and T-ATPase were increased. These findings show that probiotic solution can protect the liver, stomach and intestinal tissue from injury caused by long-time exhaustive exercise, and maintain the integrity and fluidity of cell membrane by increasing Na+/K+-ATPase, Ca2+/Mg2+-ATPase and T-ATPase activities.
