What's the difference between chyme and duodenum?

Chyme


Definition:

  • (n.) The pulpy mass of semi-digested food in the small intestines just after its passage from the stomach. It is separated in the intestines into chyle and excrement. See Chyle.

Example Sentences:

  • (1) Diversion of chyme increased the gastric secretory response, which suggests that the distal small intestine has an inhibitory role in postprandial gastric secretion.
  • (2) Patients who have an interruption of the small bowel with a high enterostomy usually need parenteral supply or reinfusion of chyme to maintain nutritional and electrolytic balances before restoring intestinal continuity.
  • (3) The concentration of chyme ingredients and volumetric velocity of the chyme transfer from the duodenum to the jejunum were investigated in experiments on normal preoperated dogs with fistulas implanted into the stomach, duodenum and jejunum after feeding different diets throughout the entire process of active digestion.
  • (4) This effect is dependent on the presence of jejunal chyme: after gastrocolic fistulae, the jejunum to colon grafts lost jejunal functional activities.
  • (5) Chronic experiment on these dogs has revealed that this operation: has no effect on frequency and amplitude of intestine contractions during the first phase of the digestive process but it is accompanied by significant relaxation of the motor intestine activity in the second phase, causes a retardation of the rate of evacuation from stomach by 56.0% in dogs subjected to extragastric vagotomy as well as pH of chyme in the duodenum by 1-1.5 units above the norm.
  • (6) The Roux-en-Y gastrojejunostomy is useful for patients with dumping, because it slows gastric emptying and the transit of chyme through the Roux limb.
  • (7) These inquiline species are not immunogenic, or at least only slightly so, since they do not feed upon the host itself but upon its intestinal chyme.
  • (8) ATPase activity was therefore essential for folate transport at the pH of the intestinal chyme.
  • (9) The optimal conditions of nutrient assimilation were revealed, using highly caloric mixtures with basic nutrient content and poly-, oligo- and monomer rations proportional to chyme.
  • (10) Thus, we demonstrated that in healthy subjects, ileocolonic transfer of chyme occurs in boluses; this transfer is impaired in patients with myopathic pseudo-obstruction.
  • (11) The mucosa of excised pieces of jejunum of fasting rats was exposed for 10 min to fresh chyme obtained from other rats which had been digesting either buttered bread or bread alone.
  • (12) Improvement of fat malabsorption is attained by using a pancreatic enzyme supplement consisting of pH-sensitive, enteric-coated microspheres (microsphere preparations) that prevent enzyme degradation in the stomach and travel with the chyme to the small intestine.
  • (13) The possibility of ascertaining the chyme flow directly (by total collection) or indirectly (with an inert marker) is described.
  • (14) Gradual increase in concentration of the main NSs occurs in the advancing chyme.
  • (15) Trypsin outputs were similar whether or not jejunal chyme was diverted.
  • (16) The content of pepsinogen in the gastric mucosa and acid phosphatase activity in the gastric chyme are adaptively altered in animals with change from natural to artificial feeding.
  • (17) The percent of fed spheres and fed 99mTc-labeled liver in each collection was counted, and liquid chyme was returned to the distal duodenum.
  • (18) In the complete chyme as well as in all fractions the crude protein and amino acid contents were determined.
  • (19) For the rats with 30 cm crossed segments, the rat that lost intestinal chyme into its partner ate 3.6 times as much food as did its partner for a period of many months.
  • (20) The carbohydrates of peas did not affect the ileal digestibility of protein, although the ileal chyme was more loose.

Duodenum


Definition:

  • (n.) The part of the small intestines between the stomach and the jejunum. See Illust. of Digestive apparatus, under Digestive.

Example Sentences:

  • (1) At the same time the duodenum can be isolated from the stomach and maintained under constant stimulus by a continual infusion at regulated pressure, volume and temperature into the distal cannula.
  • (2) However, there was not a relationship between the contraction curve of the gallbladder and the bile flow into the duodenum.
  • (3) The CL was also longer in the duodenum, whereas the CD was shortened, indicating a reduction of the wave movements from the stomach antrum to the duodenum in the ranitidine periods.
  • (4) Blunt trauma to the epigastrum may result in a retroperitoneal hematoma involving the head of the pancreas and descending duodenum.
  • (5) In both the gastric antrum and the duodenum, the first appearance of CCK-li preceded the functional activity of its target tissues.
  • (6) Although 25 Gy IORT plus 50 Gy EBRT was tolerated by the duodenum to 135 days, these doses may cause later pancreatic injury as an expression of damage to blood vessels and ducts.
  • (7) Peak serum insulin concentrations and integrated insulin secretion were also significantly greater with perfusion of the duodenum or proximal jejunum.
  • (8) The performed studies covered the effect of tuftsin, tetrapeptide stimulating many components of immunological reactions, to histamine concentration in lungs, kidneys, liver, duodenum as well as in the blood of rabbits and guinea-pigs.
  • (9) Experimental diversion of the bile flow from the lumen of the duodenum has little effect on the relative percentage of methadone vs. metabolites circulating in the blood.
  • (10) As many as 72 patients with erosive and ulcerous injuries to the stomach and duodenum were examined for the clinical efficacy of antepsin (sucralfate).
  • (11) The studies allow the interpretation that retention of food in the diverticula is not the reason for the bacterial miscolonization of the duodenum and the biliary tract, but in patients with diverticula a disturbed self-cleaning mechanism is present.
  • (12) The head and body of the pancreas between the stricture and the duodenum were normal.
  • (13) Metoprolol was introduced into the stomach with a homogenized meal containing a nonabsorbable marker, [14C]-PEG 4000, and another marker, PEG 4000, was perfused continuously into the duodenum just below the pylorus.
  • (14) Endoscopic evaluation of the stomach and duodenum was performed, with separate registration of the duodenum distally to the duodenal bulb.
  • (15) Varicose fibres were found in the myenteric plexuses of the duodenum, jejunum, ileum and colon.
  • (16) Villous tumors of the duodenum are rare, but treatment may be problematic because of their association with invasive adenocarcinoma.
  • (17) At pH 6.0, the pH of the duodenum, there is appreciable lipolytic activity in the presence of bile salts.
  • (18) During subsequent studies, hepatic bile flow was measured, and bile was returned to the duodenum through an externalized duodenal catheter.
  • (19) In 18 of the 118 stomachs the focal concentration of the parietal cells near the duodenum was greater than the other part of the antrum, reaching more than 50% of the parietal cells of the average fundic gland.
  • (20) Endoscopy and intragastral pH-metry were used to investigate the stomach and duodenum.
