食物中缺乏纤维素被认为是憩室病的重要病因。一般认为西方社会中城市居民的食物缺乏纤维素可使结肠平滑肌增厚,继而导致憩室形成。作者等用大鼠作实验,探讨两种不同含量的纤维素饲料对大鼠结肠形态学上的影响。方法:用10只Wistar大鼠分为两组,每组各5只,观察1年。出生后6周断奶。5只饲以无纤维饲料,5只饲以高纤维饲料。无纤维组将饲料中4.8％的粗纤维完全除去;高纤维组的饲料中加入麸皮,使饲料的粗 The lack of dietary fiber is considered an important cause of diverticular disease. It is generally believed that the lack of cellulose in the food of urban residents in Western society can thicken the smooth muscle of the colon, which in turn leads to the formation of diverticula. The author used rats as an experiment to investigate the morphological effects of two different contents of cellulose on colonic morphology in rats. Methods: Ten Wistar rats were divided into two groups of 5 rats each for 1 year. 6 weeks after birth, weaning. 5 were fed with no fiber feed, 5 fed with high fiber feed. No fiber group will feed 4.8% of the crude fiber completely removed; high fiber group feed added bran, the feed coarse
