title: [Changes in the fat composition and histomorphology of the liver after partial intestinal resections].
abstract: OBJECTIVE
  The partial resection of the intestine could affect the liver through alteration in nutrient absorption, loss of the bile acids via the enterohepatic circulation, alterations in the hepato-duodenobilio-pancreatic hormonal complex as well as a bacterial translocation. All these factors could sum up and induce changes in the tissue composition and in hepatic histomorphology. The aim of this experimental study is to acquire a profound knowledge of these hepatic alterations after the partial intestinal resection. M & M: 26 Dunkin Hartley guinea pigs were used: Group A with only jejunum resection, Group B with only ileum resection, and Group CtrG, the control group. They were monitored for 21 days. At the end, blood samples were taken for serum biochemical analysis. Samples of hepatic tissue were taken for histomorphological optical study. All the rest liver was homogenize and the fat liver composition was analysed (total fat, lipid fractions, phospholipids fractions and fatty acids of the liver).
  
  
  RESULTS
  There was a significant decrease in serum cholesterol in both GA & GB. There was also a decrease of the total fat/g liver tissue, without changes in the phospholipids fraction and decreases in the C18-2/C18-3 and w6/w3 ratios. There was a minimal macrosteatosis and reduction of the number of mitochondries in GB.
  
  
  CONCLUSIONS
  the partial intestinal resection, specially ileum resections, looks like influence the structural fat liver composition. However, these changes could be compensated for by the liver and oral nutrition. These findings help us to improve the liver-intestinal relationships.
