Effects of gastrointestinal polypeptides on hormone content of endocrine pancreas in the rat

American Journal of Physiology-Gastrointestinal and Liver Physiology, 1980
Although trophic actions of gastrointestinal peptides on exocrine pancreas have been shown, little is known regarding their effects in endocrine pancreas. Therefore, we measured the contents of somatostatin-like immunoreactivity (SLI), insulin and glucagon, in pancreatic extracts from rats that had been treated three times a day for 10 days with ...

Age-Related Topographical Metabolic Signatures for the Rat Gastrointestinal Contents

Journal of Proteome Research, 2011
Symbiotic gut microbiota is essential for mammalian physiology and analyzing the metabolite compositions of gastrointestinal contents is vital for understanding the microbiome-host interactions. To understand the developmental dependence of the topographical metabolic signatures for the rat gastrointestinal contents, we systematically characterized the

[Catecholamine content of tumors of the gastrointestinal tract].

Voprosy onkologii, 1983
The levels of catecholamines (adrenaline, noradrenaline, dopamine) in gastrointestinal tumors and normal tissue adjacent to malignant tumor were studied. Noradrenaline level in tumor was considerably lower than that in normal tissue. Neither adrenaline nor dopamine level showed any changes.

[Stability of akebia saponin D in gastrointestinal contents of rats].

Zhongguo Zhong yao za zhi = Zhongguo zhongyao zazhi = China journal of Chinese materia medica, 2014
In order to study the stability of akebia saponin D (ASD) in biological fluids in vitro, the determination methods of ASD were established in this study. Akebia saponin D was dissolved in artificial gastric juice, intestinal juice and gastrointestinal contents of rats, respectively, then thermostatically maintained at 37 degrees C.

How Age Changes the Content of Neuroendocrine Peptides in the Murine Gastrointestinal Tract

Gerontology, 1998
<i>Background:</i> Motility disorders in the gastrointestinal tract increase with ageing, and colorectal carcinoma is a tumor of the middle-aged and elderly. Gastrointestinal secretion, absorption, motility, cell proliferation, local immune defense and blood flow are all regulated by the neuroendocrine peptides.

Immunohistochemical determination of the estrogen receptor content of gastrointestinal adenocarcinomas.

The American surgeon, 1993
Recently there have been several reports documenting the presence of estrogen receptors (ERs) in human gastrointestinal (GI) malignancies, raising the possibility that these cancers may be hormonally manipulated. To test this hypothesis, 68 frozen GI tissue specimens were examined for the presence of ERs within the cell nuclei by immunohistochemical ...

The source of gallium-67 in gastrointestinal contents: concise communication.

Journal of nuclear medicine : official publication, Society of Nuclear Medicine, 1981
The sources of Ga-67 in gastrointestinal (GI) contents, and factors affecting its secretion were studied in rats. To prevent loss of fecal Ga-67, the anus was sutured before intravenous injection of Ga-67 citrate. Secretion of Ga-67 into the contents of the GI tract was rapid, 3, 6, and 9% of the injected dose were secreted at 1, 6, and 24 hr after ...

Endoscopic design for sampling gastrointestinal content

Abstract—Minimally invasive wireless devices, allowing the sampling of gut’s bacteria, are needed for a longitudinal understanding of the role of the microbiota on the human health. Herein, we present a novel magnetic actuation system fitting inside a 11.5 x 30.5 mm wireless ingestible capsule.
