BACKGROUND: Therapy with nonsteroidal anti-inflammatory drugs (NSAIDs) is associated with enteropathy in humans and experimental animals, a cause of considerable morbidity. Unlike foregut NSAID-associated mucosal lesions, most treatments for this condition are of little efficacy. We propose that the endogenously released intestinotrophic hormone glucagon-like peptide-2 (GLP-2) prevents the development of NSAID-induced enteropathy. Since the short-chain fatty acid receptor FFA3 is expressed on enteroendocrine L cells and on enteric nerves in the gastrointestinal tract, we further hypothesized that activation of FFA3 on L cells protects the mucosa from injury via GLP-2 release with enhanced duodenal HCO3(-) secretion...

Adolescent alcohol use comprises a significant public health concern and is often characterized by binge-like consumption patterns. While ethanol exposure in adulthood has been shown to alter the stress response, including the Hypothalamic-Pituitary-Adrenal (HPA) axis, few studies have examined whether binge-like ethanol exposure during adolescence results in enduring changes in HPA axis sensitivity in adulthood. In the present studies, adolescent Sprague-Dawley rats were given intragastric (i.g.) intubations of ethanol (4 g/kg) or vehicle once per day for three consecutive days, beginning on postnatal day (P) 30 (±1)...

Intragastric balloon (IGB) insertion has been most frequently used in the West as an effective endoscopic treatment for morbid obesity, in practice. Recently, there is a growing number of cases requiring IGB deployment for obesity treatment in Korea. One of the reported complications of IGB use is gastric perforation. A 47-year-old woman was admitted to the hospital with mild symptoms, 7 weeks after having an IGB placed. Esophagogastroduodenoscopy was performed and gastric ulcer perforation was observed in the ulcer base, where food particles were impacted...

Hyperglycemia and hypertension are considered to be the two leading risk factors for vascular disease in diabetic patients. However, few pharmacologic agents could provide a combinational therapy for controlling hyperglycemia and hypertension at the same time in diabetes. We aimed to investigate whether berberine treatment could directly reduce blood pressure in diabetes and what is the molecular mechanism underlying the vascular protection of berberine in diabetic rats. Berberine (50, 100, and 200 mg/kg/day) was intragastrically administered to diabetic rats for 8 weeks since the injection of streptozotocin...

Increasing evidence demonstrates inflammation contributes to neuronal death following cerebral ischemia. Lycium barbarum polysaccharide (LBP) has been reported to prevent scopolamine-induced cognitive and memory deficits. We recently indicated that LBP exerts neuroprotective effect against focal cerebral ischemic injury in mice via attenuating the mitochondrial apoptosis pathway. The aim of this study was to investigate the neuroprotective effects of LBP against the behavioral dysfunction induced by focal cerebral ischemia injury in mice...

Many studies have highlighted the immunomodulatory properties of the probiotic strain Lactobacillus casei BL23. Recently, we demonstrated the ability of this strain to modulate the Th2-oriented immune response in a mouse model of cow's milk allergy based on the induction of a Th17-biased immune response. The probiotic function of L. casei has been also linked to gut-microbiota modifications which could been potentially involved in the immune regulation; however, its precise mechanism of action remains poorly understood...

Bone cancer pain is a challenge for its not completely clarified mechanism and broad clinical morbidity. Therefore, novel and more effective drugs are urgent needed for improvement of patients' quality of life. Glutamate receptors have been associated with the development of the central sensitization of chronic pain. Inhibition of N-methyl-D-aspartate (NMDA) and metabotropic glutamate (mGlu) receptors can effectively attenuate bone cancer pain respectively. Herein, our results indicated that levo-Corydalmine (l-CDL), a compound from Corydalis yanhusuo W...

PURPOSE: Although the role of eosinophils in eosinophilic gastroenteritis (EGE) is not fully understood, they are believed to be a principal effector cell. Previous studies have demonstrated that eotaxin and its specific receptor, cysteine-cysteine chemokine receptor-3 (CCR3), play a central role in eosinophil trafficking into the gastrointestinal (GI) tract. Thus, we examined the targeting of CCR3 as a potential therapeutic intervention for EGE in a mouse model. METHODS: Eight- to 10-week-old BALB/c mice were intraperitoneally sensitized and intragastrically challenged with ovalbumin (OVA)...

BACKGROUND: Autophagy is required for the maintenance of cardiomyocyte homeostasis. However, excessive autophagy plays a maladaptive role in pressure overload-induced heart failure. To identify mechanisms by which Stachydrine inhibits pressure overload-induced cardiac hypertrophy, we determined inhibitory activities against activation of NADPH oxidase, reactive oxygen species(ROS) production and excessive activation of autophagy. METHODS: Stachydrine was administered intragastrically to Wistar rats after Transverse aortic constriction(TAC) and H9c2 cells were treated with Stachydrine after Angiotension II stimulation...

Deficient mucosal innate immunity is a hallmark of infectious diarrhea, such as Salmonella typhimurium (S. typhimurium)-induced gastroenteritis. Here, we report that oral administration of a 4,4'-diaponeurosporene-producing Bacillus subtilis (B.s-Dia) could improve mice mucosal immunity, as showed by an increased resistance against S. typhimurium infection. Intragastric administration of B.s-Dia for 7 days could increase the secretion of CCL20 by intestinal epithelial cells (IECs) and then recruit more dendritic cells...

Relationships of toxicities from intravenous (i.v.), intraperitoneal (i.p.), subcutaneous (s.c.) and intragastric (i.g.) exposure routes to mice were investigated. Regression analysis showed that the toxicities from i.v. route is strongly correlated with i.p. and s.c. routes, but poorly with i.g. route. Close toxicities from different routes for some compounds indicate that distribution rate is the determining step and dictates chemical concentration at the target site(s). On the other hand, the absorption rate is the determining step for many compounds, which lead to different toxicities between exposure routes...
