An investigation into the relationship between small intestinal fluid secretion and systemic arterial blood pressure in the anesthetized rat [PDF]

open access: yes, 2015
In the absence of an ability to absorb fluid by cellular uptake mechanisms, fluid movement in vivo from the perfused rat intestine is absorptive when the diastolic blood pressure is normal or very low but is secretory when blood pressure falls below ...

Dietary saturated fatty acid content affects lymph lipoproteins: studies in the rat.

open access: yesJournal of Lipid Research, 1983
We examined effects on intestinal absorption of cholesterol and triglycerides and intestinal lipoprotein formation by feeding rats diets in which saturated fatty acids (palmitic plus stearic) comprised 78%, 68%, 48%, or 38% of triglyceride fatty acids ...

Diet-induced iron deficiency in rats impacts small intestinal calcium and phosphate absorption [PDF]

open access: yes, 2021
Aims: Recent reports suggest that iron deficiency impacts both intestinal calcium and phosphate absorption, although the exact transport pathways and intestinal segment responsible have not been determined.

Gintonin absorption in intestinal model systems

open access: yesJournal of Ginseng Research, 2018
Background: Recently, we identified a novel ginseng-derived lysophosphatidic acid receptor ligand, called gintonin. We showed that gintonin induces [Ca2+]i transient-mediated morphological changes, proliferation, and migration in cells expressing ...

Reduction in jejunal fluid absorption in vivo through distension and cholinergic stimulation not attributable to enterocyte secretion [PDF]

open access: yes, 2018
Jejunal fluid absorption in vivo was reduced by distension and by hydrostatic pressure and further declined on adding E. coli STa enterotoxin but no net fluid secretion was detected.

Gastro-intestinal absorption of isoniazid and rifampicin in patients with intestinal tuberculosis [PDF]

open access: yes, 1990
The gastro-intestinal absorption of isoniazid and rifampicin was studied in 12 patients with intestinal tuberculosis (10 slow and 2 rapid acetylators of isoniazid) and compared with that in 18 patients with pulmonary tuberculosis (8 slow and 10 rapid ...

The use of the Ussing chamber system to investigate iron absorption by the duodenum, jejunum and ileum in the mouse : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Physiology at Massey University, Palmerston North, New Zealand [PDF]

open access: yes, 2002
Iron deficiency anaemia is found in approximately 30% of the worlds population and is particularly prevalent in developing countries. The majority of these deficiencies are due to insufficient absorption of iron from the diet.

Diarrhea induced by insufficient fat absorption in weaned piglets: Causes and nutrition regulation

open access: yesAnimal Nutrition
Fat is one of the three macronutrients and a significant energy source for piglets. It plays a positive role in maintaining intestinal health and improving production performance.
