jasminum amplexicaule buch.-ham. (oleaceae) has been commonly used in the traditional medicine in dysentery, diarrhoea and bellyache in china. in the present work, the methanol extract of jasminum amplexicaule (jme) was examined for pharmacology on human colonic epithelial cell line t84 by the short-circuit current technique. the results showed that pretreatment of t84 cells with jme produced a...

objective: acinetobacter baumannii (a. baumannii) has a good potential to colonize on various surfaces. as a virulence factor, adhesion to surfaces is the first step in colonization. the two-partner secretion system (tps) proteins are key factors for bacterial attachment. the purpose of this study is to identify and study the role of this family of proteins in adhesion of a. baumannii to human ...

objective: gut–brain axis (gba) is very important in creation and modulation of gastrointestinal problems. aloe vera gel has gastroprotective properties. the purpose of this study was to evaluate the effect of aqueous extract of aloe vera leaves on the gastric acid secretion and brain and intestinal water content following acetic acid gastric ulcer induction. materials and methods: gastric ulce...

isolation of rat islets of langerhans was carried out by using collagenase and the destruction of exocrine tissue was performed through the injection of hanks' solution into the common bile duct. the identification of the islets was done by techniques including the use of a stereomicroscope against a black background. vital staining was done by an injection of neutral red solution through ...

migratory birds can become long-distance vectors for a wide range of microorganisms. the objective of the present study was to investigate the presence of cryptococcus neoformans in the cloacae, crop and nasal cavity of migratory birds in order to assess their role as potential reservoirs and/or mechanical vectors of human and animal cryptococcosis. a total of 700 samples (cloacae, crops and na...

tumor necrosis factor-related apoptosis-inducing ligand (trail), a member of tnf family, is an interesting ligand which selectively induces apoptosis in tumor cells and, therefore, it has been developed for cancer therapy. this ligand has been produced by various hosts such as e.coli. however, protein expression in e.coli cytoplasm leads to problems such as incorrect folding, reduction in biolo...

introduction: the protective and antisecretory effects of dopamine agonists on the stomach have been already reported, but the effect of bromocriptine (d2 dopamine agonist) on histamine stimulated gastric acid secretion (gas) needs to be investigated. methods: for gastric sampling, animals were anesthetized and a polyethylen tube was introduced into the stomach through esophagus. a cannula was ...

abstract injection of sulpiride (d2 receptor antagonist, antipsychotic drug) into vmn hypothalamus, increased gastric volume secretion and decreased gastric ph. the present study the effect of sch23390 (d1 dopamine receptor antagonist) on the gastric acid secretion and its acidity were studied. 70 rats were divided into 7 groups: two control groups, two sham groups given medicine solvents, a sc...

introduction: the effect of esophageal distension (ed) on gastric motility has been well documented, but a few investigations have been carried out on the effect of ed on gastric secretion. the aim of this study was to investigate the effect of ed on gastric acid and pepsin secretion and the mechanism(s) involved. methods: male adult wistar rats (200-240 g) were anesthetized with urethane (1.2 ...
