• segment
  • METHODS: A closed 10 cm segment of upper jejunum was exposed to 15 micrograms of cholera toxin for two hours prior to closed segment perfusion with plasma electrolyte solution containing a non-absorbable volume marker, [14C]-polyethylene glycol. (bmj.com)
  • METHODS: A 25 cm segment of rat jejunum was perfused in situ with iso-osmotic solutions containing either (1) saline, (2) D-arginine 20, (3) L-arginine 20, (4) L-NAME 0.1, 1, or 20 mmol/l, or (5) a combination of L-arginine 20 and L-NAME 0.1, 1, or 20 mmol/l. (bmj.com)
  • study
  • It is possible that glutamine transport was maintained in this previous study, because the jejunum had not been exposed to luminal glutamine. (physiology.org)
  • cells
  • Many goblet cells in the mucosa produce mucus to protect the intestinal walls and to lubricate chyme passing through the jejunum. (innerbody.com)
