Iag. Desegura et al., PLASMA ENTEROGLUCAGON LEVELS IN DIFFERENT MODELS OF INTESTINAL RESECTION IN THE RAT, Digestive diseases and sciences, 39(1), 1994, pp. 65-68
To assess the influence of the different intestinal segments On the pl
asma enteroglucagon level, three models of intestinal resection in the
rat were studied (jejunal, ileal, 90%). The basal values for this pep
tide and those obtained after an infusion of intraduodenal glucose wer
e compared. The results obtained in basal/post-glucose infusion were:
50% proximal (jejunum): 220/728 pg/ml; 50% distal (ileum): 10/233 pg/m
l; and the middle 90%: 108/297 pg/ml. The glucose infusion produced a
maximal response, permitting a better evaluation of the differences am
ong the three resection models. The highest levels corresponded to the
group in which the entire ileum was conserved.
