Enteral fish oil immunonutrition prevents pulmonary dysfunction during intra-abdominal sepsis and hypertension in rats / 肠外与肠内营养

ABSTRACT

Objective:To investigate whether an enteral fish oil immunonutrition during intra-abdominal sepsis and hypertension dose improve pulmonary function.Methods: We divided 25 rats into three groups.The rats were supplemented by gavage with(Ⅰ)normal saline as control group(9);(Ⅱ)fish oil(0.3%,8) and(III)fish oil(0.6%,8).The cytokine levels were analyzed.The lungs were harvested,stained with hematoxylin-eosin,and analyzed. Results:Intra-abdominal sepsis and hypertension induced thickening of alveolar walls and inflammatory reaction.Fish oil decreased expression of pro-inflammatory cytokines(TNF-? and IL-1?),inhibitted infiltration of MPO positive cells,and protected pulmonary structure.Conclusion: The lung may be protected by an enteral fish oil nutrition through attenuating inflammatory reaction.
