Fish oil ameliorates the intra-abdominal sepsis and hypertension-induced ileus / 肠外与肠内营养

ABSTRACT

Objective:To investigate whether the fish oil improves intestinal motility function during intra-abdominal sepsis and hypertension.Methods: 25 rats were divided into three groups.The rats were supplemented by gavage with: ①normal saline as control group(n=9);②fish oil(0.3%,n=8)and ③fish oil(0.6%,n=8)for 4 weeks before operation.The rats were killed on the 24th hour after operation.In vitro ileual smooth muscle contractions were recorded.Ileum sections were assessed pathologically.Immunopositivity of c-kit as markers of ICC-MY by confocal microscopy were evaluated.Results: In the bowel segment with NS,muscles showed a significant reduction in the frequency of contraction compared to that with FO.This change was associated with the changes of ICC-MY network.Conclusion:The intestinal motility may be protected by an enteral fish oil nutrition through attenuating injury of ICC-MY network.
