The possibility of glandular stomach cancer being induced was studied in 75 random bred white rats exposed to chrysotile asbestos. A perforated polyethylene capsule containing 100 mg asbestos and filler (beef fat and natural wax mixture 1:1) was introduced in an artificial bag placed on the greater curvature of the stomach. A capsule containing filler only was introduced in a similar way in 40 ...

thyroid hormoned are known to influence acid and pepsin secretion,though exact mechanism(s) are not fully understood.in this study distention-stimulated acid and pepsin secretionof hypo and hyperthyroid rats were compared with controls.each group consisted of 8 N-mari rats from both sexs,weighing  246.6+_9.2g. hypo and hyper thyroid states were induced by administration of methimazole(500mg/l H...

Effects of afferent stimulation of the lingual nerve (LNAS) on gastrointestinal motility and the reflex pathways which mediate the response to LNAS were investigated in rats. LNAS induced excitatory, inhibitory or biphasic responses in the stomach, duodenum and proximal colon. These responses continued after bilateral vagotomy, but were abolished after additional bilateral splanchnicotomy or tr...

1. Inflation of the cardiac stomach of the cod induced rhythmic contractions of the muscles and a slow increase in stomach volume towards a maximum. After deflation, the stomach remained relaxed and easily distensible for one or more hours. Section of the vagal tracts to the stomach did not change the response. 2. Inflation in vitro produced a somewhat faster relaxation and a much faster recove...

BACKGROUNDS/AIMS The aim of this retrospective study is to compare stomach cancer incidence, characteristics between gallstones, cholecystectomy and control groups. It also aims to investigate key variables' potential effects on overall survival. METHODS A total of 99 patients, diagnosed with stomach cancers between April 1994 and December 2015, were identified. We excluded stomach cancer pat...

The stomach is traditionally regarded as a hollow muscular sac that initiates the second phase of digestion. Yet this simple view ignores the fact that it is the most sophisticated endocrine organ with unique physiology, biochemistry, immunology and microbiology. All ingested materials, including our nutrition, have to negotiate this organ first, and as such, the stomach is arguably the most im...

PURPOSE Small intestinal function returns first after surgery, and then the function of the stomach returns to normal after postoperative ileus (POI). The aim of this study was to investigate inflammatory responses in the muscle coat of stomach and small intestine in guinea pig POI model. MATERIALS AND METHODS The distance of charcoal migration from pylorus to the distal intestine was measure...

This study aimed to understand the structural devolution of 10% w/w rennet-induced (RG) and transglutaminase-induced acid (TG) gels in H2O D2O under vitro gastric conditions with without pepsin. The real-time structure at a nano- (e.g. colloidal calcium phosphate (CCP) micelle) micro- (gel network) level was determined using ultra-small (USANS) small-angle neutron scattering (SANS) electron mic...
