Question

英语翻译
Eight-month-old Sprague-Dawley rats were fed on diets containing dietary fiber at the 5% level for 3 weeks to examine the effect on the lipid metabolism and immune function.Among cellulose,guar gum,partially hydrolyzed guar gum(PHGG),glucomannan and highly methoxylated pectin,guar gum induced a significant decrease in the food intake and weight gain,as well as a signimal increase in the liver weight .In addition ,the epidydimal adipose tissue weight of the rats fed on PHGC was significantly highter than that of the rats fed on cellulose .There was no significant effect on the serum lipid levels,but the serum IgG level of the rats fed on guar gum was significantly lower than that of the rats fed on cellulose.The IgA and IgG productivity in mesenteric lymph node (MLN) lymphocytes was significantly higher in the rats fed on guar gum ,glucomannan and pectin than on those fed on cellulose ,while the effect on Ig productivity in spleen lymphocytes was not as marked.In addition,only guar gum induced a significant increase of IgM productivity in MLN lymphocytes when compared to the cellulose group.These results suggest that enhancement of the immune function by dietary fiber is expressed in the gut immune system.

Answer 1

8个月大的SD大鼠饲喂含3周的5％的水平,膳食纤维膳食研究的脂质代谢及免疫效果function.Among纤维素,瓜尔豆胶,部分水解瓜尔豆胶（PHGG）,葡甘聚糖,高甲氧基果胶,瓜尔豆胶诱发的食物摄入量和体重明显下降,以及在肝脏重量signimal增加.此外,该epidydimal对PHGC饲养大鼠脂肪组织重量明显高于新海对纤维素饲养大鼠.没有对血脂水平显着影响,但血清IgG对瓜尔豆胶饲养大鼠水平显着低于对cellulose.The IgA和IgG的生产力在肠系膜淋巴结喂养大鼠的节点（肠系膜）淋巴细胞显着高于对瓜尔豆胶,葡甘聚糖,比那些吃纤维素果胶饲养大鼠,而对脾淋巴细胞免疫球蛋白在生产力的影响是不作为marked.In此外,只有瓜尔豆胶诱导的显着增加生产力的抗体肠系膜淋巴结细胞相比,结果表明纤维素group.These由膳食纤维,对免疫功能的增强功能是在肠道中表达的免疫系统.
