Objective: To evaluate the splenic parenchymal blood distribution through scintigraphic study. Methods: Thirty Wistar rats were randomly divided into six groups (n = 5). Group 1 (spleen – 30 minutes) and Group 2 (spleen – 90 minutes) underwent laparotomy with direction of blood flow to the spleen by ligature of the aorta near the iliac bifurcation and splanchnic vessels, keeping blood flow only...
AIM To investigate the immunological repertoire in the peritoneal cavity of gastric cancer patients. METHODS The peritoneal cavity is a compartment in which immunological host-tumor interactions can occur. However, the role of lymphocytes in the peritoneal cavity of gastric cancer patients is unclear. We observed 64 patients who underwent gastrectomy for gastric cancer and 11 patients who und...
The bioavailability of drugs is determined by gastrointestinal physiological factors and the physicochemical property of drugs. The presence of food changes the physiological functions of gastrointestinal mucosa (e.g., gastric pH, gastric emptying, hepatic blood flow) which may lead to increase or decrease in the bioavailability of drugs. Intestinal absorption of penicillin, captopril, ciproflo...
The new H2-receptor antagonist, ranitidine, has been compared with cimetidine and metiamide as an inhibitor of gastric acid secretion in the dog. All three compounds were effective both intravenously or by mouth in inhibiting secretion induced by histamine, pentagastrin, or bethanechol. This inhibition was mainly attributable to a reduction in the volume of secretion, although there was also a ...
Changes in meal composition and duration affect postprandial endothelial function in healthy humans.
Endothelial function, measured by flow-mediated dilatation (FMD), predicts cardiovascular events and is impaired postprandially. The objective of this study was to evaluate the effects of changes in composition or duration of ingestion of a meal, which slows gastric emptying and/or small intestinal nutrient exposure, on postprandial endothelial function. Twelve healthy subjects (6 male, 6 femal...
The response of mass activity of the gastric vagal afferent nerve to intravenous administration of interleukin-1 beta (IL-1 beta) and the involvement of cholecystokinin (CCK) in the response were investigated in pentobarbital-anesthetized rats. Intravenous administration of 2 micrograms.kg-1 of IL-1 beta caused an increase in the afferent activity, which reached 150% of control activity by 30 m...
Aneurysm formation is a potential complication of granulomatosis with polyangiitis (GPA), previously known as Wegener's granulomatosis. It is a very rare complication, but immediate diagnosis and therapy should be performed because an aneurysm can be life-threatening if it ruptures. An accessory left gastric artery (ALGA) is also a rare variant gastric artery that may obtain its blood supply fr...
