Experimental study on intestinal adaptation after entestinal surgery Special rifference to gut hormonl and evoked potentiel dtterence.

本文用犬和大鼠研究了回肠转位术（IJT）或术后肠道适应性的影响。杂种犬术后5、12周和6个月观察高肠溶蛋白血症。术后第5周，肠吻合口60min的胃肠道充盈模式出现一个与甘氨酸相对应的主峰，术后第14周组织学检查显示，小肠及间置回肠段肠粘膜均出现肥大，隐窝绒毛与假手术组相比有显著性差异。葡萄糖诱发电位差异的研究表明，回肠的100mMPD和PDmax均高于空肠，术前回肠的100mMPD和PDmax均高于空肠，空肠的100mMPD和PDmax均高于回肠。Corr keptbuylr leuel. IJT后10天观察到有绒毛，但IJT后40天绒毛消失。光镜下观察到40天后，光镜下观察到的光镜下

The effect of ileojcjunal transposition (IJT) or the intestinal adaptation after surgery was investigated in both dogs anf rats. Hyperenteroglu cognomina was observed 5,12 weeks and 6 months after operation in mongrel dogs. G.l filhation pattern of the sewn 60miuuts after test meal loading at 5 weeks after IJT had a main peak which correspondes glycentin Histological examination revealcd intestinal mueosal bypertrophy in all part of small in testin as well as interposed ileal segment.14weeks after IJT.There was a significant difference in crypt-villasratis betweein IJT group and sham group.
