通过饮食补充钙能减少大鼠结直肠肿瘤的发生率,还能减少人或动物肠道细胞的更新。作者采用Sprague-Dawley鼠(n=99)分为2组。1组作80％中小肠切除,另1组作空肠横切。每组动物有一半在饮水中加入乳酸钙24g/l。收集术后7周的粪便,以测定游离胆汁酸和游离脂肪酸。在3种不同浓度的钙中持续培养对照组的结肠粘膜,随后用有丝分裂中断法(Stathmokinetic)测量
Supplementation of calcium through diet can reduce the incidence of colorectal tumors in rats, but also reduce the regeneration of intestinal cells in humans or animals. The authors used Sprague-Dawley rats (n = 99) divided into two groups. A group of 80% for small intestine resection, the other group for jejunal transection. Half of each animal in the drinking water added calcium lactate 24g / l. Stool was collected 7 weeks after surgery to determine free bile acids and free fatty acids. Colonic mucosa of the control group was continuously cultured in 3 different concentrations of calcium and subsequently measured by the mitotic disruption method (Stathmokinetic)
