Stimulation of Ca2+ absorption can counteract hypocalcemia at the onset lactation. The plant bioactive lipid compound (PBLC) menthol is an agonist for nonselective cation channels transient receptor potential (TRP) family. It acutely stimulated in ruminal epithelia nonadapted animals ex vivo and caused higher plasma concentrations cows sheep vivo. To elucidate pathway by which feeding increases...

Gastrointestinal stromal tumors (GISTs) of the duodenum are relatively rare and difficult to diagnose in early stage because it lacks pathognomonic symptoms. Here, we report a case of multiple GISTs involving the third and fourth portions of the duodenum and proximal jejunum, which were revealed in an emergent laparotomy. A 40-year-old, previously healthy man was referred to the Emergency Depar...

Jejunum and ileum from vitamin D-deficient rats actively secreted calcium when studied in vitro, while duodenum from these animals actively absorbed calcium. Acute repletion with a single physiologic dose of 25-hydroxyvitamin D3 (25-OH D3) (15 i.u.) increased calcium absorption in duodenum and ileum but had no effect on jejunum. Studies of the distribution of 25-OH D3 and its metabolites in the...

Introduction: Considering the long traditional history of anti-inflammatory and anti-spasmodic effects of Matricria spices on the gastrointestinal system, the present study aimed to investigate the role of calcium channels and Histamine receptors in the inhibitory effects of hydroalcoholic dry extract of German chamomile (Matricaria recutita L.) on the isolated rabbit jejunum. Methods: All ...

Abstract Forty Holstein bull calves were fed 1 of 3 starch-based milk replacers for either 10 or 35 days to determine responses in organ mass and small intestinal length. Calves (87.2 ± 7.7 kg) bottle-fed a cornstarch-based replacer (727 g cornstarch daily) alone, with added casein (154.7 g/d) glutamate (45.5 d. Prior receiving treatments commercial 12 15 weeks so that measures length collected...

This research was conducted with aim knowing effect adding ration at different levels on internal organ profile broiler chickens. method used this study a completely randomized design factorial pattern 3 treatments (factor A) 4 B) using 2 replications for each replication or experimental unit containi...

OBJECTIVE The present study has been undertaken with the main objective of evaluating the aqueous extract of flowers of Muntingia calabura for antispasmodic activity on isolated rabbit's jejunum. MATERIALS AND METHODS The study was carried out on isolated rabbit's jejunum preparations. The aqueous extract of flowers of M. calabura was applied in different doses by cumulative manner without wa...

OBJECTIVE To determine alterations in quantities and distributions of natural antimicrobials following ischemia-reperfusion injury. We hypothesized that these compounds would be upregulated in areas of small intestine where changes in permeability and cellular disruption were likely and where protective mechanisms would be initiated. METHODS Rats with ischemia-reperfusion underwent superior m...

During intestinal absorption, dietary polyglutamyl folates are hydrolyzed to monoglutamyl folates by pteroylpolyglutamate hydrolase (folate conjugase). This enzyme is present in the brush border and intracellular fractions of human jejunal mucosa. We compared the activities of brush border and intracellular folate conjugase (BBFC and ICFC), and other mucosal enzymes in the jejunum in continuity...
