35只大鼠随机分为四组,A组为正常对照组,B组为谷氨酰胺肠外营养组(GLN-TPN),C组为不含GLN的常规TPN组和经肠道营养的D组。内毒素以2mg/kg/d的剂量,混入营养液或生理盐水中,持续滴注5天。结果显示,B组肠壁蛋白质和DNA含量高于C组,其中回肠蛋白质含量有显著差别(P<0.05)。在绒毛高度、小肠粘膜及全层厚度等指标B组也明显优于C组(P<0.05),经肠道营养的D组在上述组织学观察数值上均与正常相近,且粘膜厚度、绒毛高度均超过正常值(P<0.05)。B、D二组肠道内细菌移位率均低于C组(P<0.05)。研究结果提示,加入GLN的TPN有助于防止败血症大鼠肠萎缩及细菌移位。早期应用经肠道营养更具有积极的生理意义。
35 rats were randomly divided into four groups: group A was normal control group, group B was glutamine parenteral nutrition group (GLN-TPN), group C was conventional TPN group without GLN and group D group. Endotoxin 2mg / kg / d dose, mixed with nutrient solution or saline, continuous infusion for 5 days. The results showed that the content of protein and DNA in the intestinal wall of group B was higher than that of group C, and the content of ileal protein was significantly different (P <0.05). In group B, the indexes of villus height, small intestinal mucosa and full thickness were also significantly better than those in group C (P <0.05). The intestinal histological values in group D of intestinal nutrition were similar to those in normal group, and mucosal thickness , The height of the villus exceeded the normal value (P <0.05). The intestinal bacterial translocation rates in group B and group D were lower than those in group C (P <0.05). The results suggest that the addition of GLN TPN helps prevent intestinal atrophy and bacterial translocation in rats with sepsis. Early application of enteral nutrition more positive physiological significance.
