摘要
选用42-56周龄BALB/C小鼠150只,随机分为常温对照、热应激、高温石膏用药3组,每组50只。用药组小鼠每日灌喂石膏水提物0.25 mL/只,2次/d;高温和低温对照组小鼠每日灌喂等量的生理盐水,每天2次,在试验的1,4,6,9 d结束后,每组随机挑出6只小鼠(雌雄各半)处死,分别采取十二指肠、空肠、回肠样品进行肠绒毛测定。结果表明:热应激会使小鼠的小肠绒毛长度变短,其中对十二指肠影响最大,回肠最小;石膏水提物能在高温下对小肠起到保护作用,使绒毛长度增长,其中以空肠效果最为明显。
The 150 mice at the age of 42～56 weeks were divided into 3 groups randomly. The group of fed herbal medicine was fed by the plaster water 0.25 mL/each, 2 times/d; The group of normal temperature and the group of heat stress were fed by physiological brine 0.25 mL/each, 2 times/d. At 1,4,6,9 d in the experiment, 6 mice selected from every group randomly were sentenced to death, and the villus length of duodenum, jejunum and ileum of the mice were menstruated to detect the effect of the plaster water on the intestinal villus length of the mice in heat stress. The results indicated that： heat stress caused the intestinal villus length shortening, the influence of the duodenum received was the most, and that of the ileum was the smallest; the plaster water had protective function on the length of the intestinal villus in hot stress.
