liver, and intestinal walls are combined with digestive materials as they move through the small intestine, encouraging them to contact the absorbent surface. In the small intestine, appetizer waves transport digestive substances, while rhythmic segmentation breaks up these substances, ...
Amoxicillin absorption was rate and site dependent in the gastrointestinal tract. The drug was well absorbed in the duodenum and jejunum, with no significant differences in absorption when administered as a bolus or 4‐hour infusion, but absorption was decreased and rate dependent in the ileum, ...
With respect to the mechanisms by which antifolates and CP cause differential toxicity, it is well established that folate absorption and drug metabolism are greater in the human small intestine compared to the large intestine28,29,30,31. Thus, differential toxicity observed in murine intestinal ...
The data showed excellent absorption of the drug from all intestinal segments studied (jejunum 0.97±0.16, ileum 0.7±0.13, right colon 0.7±0.13, and left colon 0.88±0.19 μg/cm/min), despite a concomitant secretion of sodium chloride and water. No statistical differences in absorptive ...
The large intestinal epithelium is specialized for mucus secretion, salt and water absorption The epithelial component of the mucosa of the large bowel is a mixture of absorptive cells and mucous cells. These are arranged as simple, straight, non-branching tubular downgrowths extending from the sur...
“Watery stools” can be caused by any condition that causes food residue to be rushed through the large intestine too quickly to allow water absorption. This may be due to bacterial irritation of the canal. Dictionary of Unfamiliar Words by Diagram Group Copyright © 2008 by Diagram Visual ...
Absorption of insulin from the intestinal tract. Oral administration of insulin to a patient with blockage of the pancreatic duct and secondary achylia produced no change in the level of the blood sugar. ... F Chrometzka,W Wedderer - 《Ztsc.hr.ges.exp.med》 被引量: 11发表: 1936年 ...
endocrine cell densities in patients with irritable bowel syndrome T Mazzawi1,2,3, T Hausken2,3, D Gundersen4 and M El-Salhy1,2,3 BACKGROUND/OBJECTIVES: To determine the large intestinal endocrine cell types affected following dietary guidance in patients with irritable bowel syndrome (IBS). ...
The enzyme responsible for this hydrolysis is glutamate carboxypeptidase II, also known as folylpoly-γ-glutamate carboxypeptidase or folate conjugase, found in the intestinal brush border of humans. To our knowledge, no studies to date have examined either the presence of folate conjugase or its ...
Intestinal solute carriers: an overview of trends and strategies for improving oral drug absorption. A large amount of absorptive intestinal membrane transporters play an important part in absorption and distribution of several nutrients, drugs and prodrug... B Steffansen,CU Nielsen,B Brodin,... -...
