RESUMO
Objective To study the effect of portal vein blocking on the permeability of the intestinal mucosa in pigs. Methods Healthy Rongchang pigs were divided into 3 groups: ① sham operation group(SO), ② portal vein clamping for 45 min group (PVC-45'), ③ portal vein clamping for 60 min group (PVC-60'). Urine lactulose/mannitol(L/M) ratio was measured after portal vein blocking. Results The L/M ratio was increased significantly (P<0.05) in PVC-45' and 60' groups than in SO group, with that of PVC-60' higher than that of PVC-45' group, but not significantly. Conclusion The increase of intestinal mucosal permeability after portal vein blocking is an early and important index for the damage of the intestinal mucosa barrier.
