【摘要】：本试验旨在研究甘蔗提取物(sugar cane extract,SEC)对热应激大鼠肠道组织的影响,为SCE在动物生产上的应用提供理论依据。选取21日龄雌性Wistar-Imamichi大鼠20只,按体重均分为4组,分别是对照组(NT)、SCE组(SCE)、热处理组(HT)、SCE热处理组(SH),其中SCE组和SH组均是日粮中添加2.16%的SCE纯品。NH组和SCE组处于25℃恒温环境中,HT组和SH组每天在38℃温控环境中暴露3 h(12:00-15:00),试验期10 d。结果表明:SCE和热处理对空肠IL-1β、IL-6和TNF-αmRNA表达以及回肠IL-1β和TNF-αmRNA表达无显著影响,但SCE显著降低IL-6在回肠上的基因表达;热处理使十二指肠杯状细胞数目增多,其中SCE和热处理组尤为显著;空肠和回肠各组杯状细胞无明显变化。由此可见,甘蔗提取物可显著降低热应激大鼠回肠组织IL-6基因表达水平,且甘蔗提取物和热应激影响十二指肠杯状细胞数目。
[Abstract]:The purpose of this study was to study the effect of sugar sugar cane extract (cane extract) from sugarcane on intestinal tissue of heat stressed rats, and to provide theoretical basis for the application of SCE in animal production. Twenty 21-day-old female Wistar-Imamichi rats were divided into 4 groups according to their body weight. SCE and SH groups were fed diets supplemented with 2.16% pure SCE. NH and SCE groups were exposed to temperature control environment at 38 鈩，
