Alanyl-glutamine protects the intestinal barrier function in trained rats against the impact of acute exhaustive exercise

Braz. j. med. biol. res; 53 (5), 2020
Strenuous exercise triggers deleterious effects on the intestinal epithelium, but their mechanisms are still uncertain. Here, we investigated whether a prolonged training and an additional exhaustive training protocol alter intestinal permeability and the putative effect of alanyl-glutamine (AG) pretreat...

Glutamine protects intestine against ischemia-reperfusion injury by alleviating endoplasmic reticulum stress induced apoptosis in rats

Acta cir. bras; 35 (1), 2020
Abstract Purpose Glutamine, as an essential part of enteral nutrition and parenteral nutrition agent, has been widely recognized to be a kind of important intestinal mucosa protectant in clinical practice and experimental research. However, the mechanisms of its protective effects are still not fully u...

A suplementação com quercetina previne mudanças em células imunorreativas à serotonina e caspase-3 do jejuno de ratos diabéticos

Arq. gastroenterol; 56 (4), 2019
ABSTRACT BACKGROUND: Serotonin (5-HT) is present in the epithelial enterochromaffin cells (EC), mast cells of the lamina propria and enteric neurons. The 5-HT is involved in regulating motility, secretion, gut sensation, immune system and inflammation. OBJECTIVE: Evaluate the effects of diabetes and ...

Effects of anti-TNF-α in experimental diversion colitis

Acta cir. bras; 34 (10), 2019
Abstract Purpose: To evaluate the effects of infliximab on the inflammation of the colonic mucosa devoid from fecal stream. Methods: Twenty-four rats were submitted to a Hartmann's procedure. They remained for 12 weeks with the fecal derivation to development of diversion colitis on excluded colorectal...

Effect of copaiba oil in intestinal mucosa of rats submitted to hypovolemic shock

ABCD (São Paulo, Impr.); 32 (3), 2019
ABSTRACT Background: Hypovolemic shock is a common disease in polytrauma patients and may develop ischemia in various organs, increasing morbidity and mortality. The bowel is usually most affected by this condition. Aim: To evaluate the effects of copaiba oil on the intestinal mucosa's injury of rats ...

Oxidative stress assessment in intestine of newborn rats submitted to hypoxia and reoxygenation with tadalafil

Acta cir. bras; 34 (4), 2019
Abstract Purpose: To evaluate the functional and structural response of tadalafil effects in the intestinal mucosa, using an experimental model of hypoxia and reoxygenation injury in rats. Methods: The animals were divided into 4 groups: CTL, H/R, H/R+Td and M+Td. The newborn rats allocated in groups ...

Enemas with mesalazine increase the tissue contents of mucins in the colonic mucosa devoid of fecal stream

Acta cir. bras; 34 (4), 2019
Abstract Purpose: To evaluate the inflammatory reaction and measure the content of mucins, in the colonic mucosa without fecal stream submit to intervention with mesalazine. Methods: Twenty-four rats were submitted to a left colostomy and a distal mucous fistula and divided into two groups according t...

Evaluation of growth performance and gastro-intestinal parameters on the response of weaned piglets to dietary organic acids

An. acad. bras. ciênc; 90 (1), 2018
ABSTRACT Two experiments (E) were carried out to evaluate the effects of fumaric acid and an acidifier blend [composed by calcium formate, calcium lactate and medium-chain fatty acids (capric and caprylic)] in piglet diets containing colistin (40 ppm) or halquinol (120 ppm) on performance, diarrhea incid...

Dietas altas en grasas y sus efectos sobre el intestino

El objetivo de esta revisión fue exponer el conocimiento actual sobre la relación existente entre dietas altas en grasa (DAG), alteraciones morfológicas de la mucosa intestinal, efectos inflamatorios y cáncer intestinal. Las DAG inicialmente producen aumento de la microbiota patógena, lo que reduce ...

Rev. Col. Bras. Cir; 45 (5), 2018
RESUMO Objetivo: examinar os efeitos da sinvastatina na mucosite gástrica e intestinal após o tratamento com 5-fluorouracil (5-FU), determinados pela expressão de citocinas e histologia em ratos. Métodos: ratos pesando 270±15g foram divididos em dois grupos. O grupo 5-FU+salina foi tratado com 5-F...
