摘要
用氨甲蝶呤诱发小肠炎后 ,SD大鼠分别饲喂Gln含量不等的氨基酸营养液 ,结果表明 ,72h内 ,第一组 (零剂量组 )大鼠的死亡率为 6 6 .7% ,第二组 (含Gln质量分数 2 % )为 16 .7% ,第三组 (活性肽组 ,含Gln质量分数 2 0 % )和第四组 (结晶氨基酸液 ,含Gln质量分数 2 0 % )为 0 ,并且第三组和第四组的体重、蔗糖酶活、氨肽酶活、DNA和RNA的含量增加 ,说明Gln活性肽营养液对小肠具有明显的营养作用。
Administration of methotrexate to rats caused severe enterocolitis with 66.7% and 16.7% mortalities within 72 hours in the first group (control group) and the second group (2% Gln) respectively. But the sucrase and aminopeptidase activities,DNA and RNA contents of small intestine in rats of group 3 (glutamine bioactive peptide group) and group 4(20% Gln) were significantly higher than those of group 1 and group 2. These results showed that glutamine bioactive peptide enhanced digestion processes, so it can be used to improve nutritive conditions of the small intestine.
