Stimulation of localised pyloric contractions may be an important mechanism in the slowing of gastric emptying by cholecystokinin infusion. The effect of cholecystokinin octapeptide on fasting pyloric motility was investigated in 14 healthy volunteers. Antral, pyloric, and duodenal pressure responses to normal saline and graded injections of cholecystokinin octapeptide (5, 10, and 20 ng/kg) wer...

The modulation of the pyloric network of the stomatogastric ganglion (STG) of the lobster Panulirus interruptus by the neuropeptide proctolin is described. First, the effects of proctolin on the pyloric motor patterns were characterized in terms of frequency and phase relations. Pyloric cycle frequency and lateral pyloric (LP) neuron activity increased and ventricular dilator (VD) neuron activi...

Sir, I should like to report a case of hypertrophic pyloric stenosis presenting at the age of 2 years 6 months. This male, only child was admitted with a 5-day history of fever and vomiting, which was not bile stained. His past history was normal and he had not vomited in infancy. The vomiting settled within two days and he was discharged to be readmitted 8 days later with a recurrence of his s...

Surgeons should perform several tasks during medical operations (i.e. suture, ligature, etc.). In particular, the suture and ligature require high level skills in order not to damage skin or tissues. Therefore, many trainees practice using surgical training models. However, these training models focus only on helping trainee to learn a surgical procedure by simulation and imitation, and do not ...

Introduction: Gastrointestinal Endoscopy is  as a diagnosis and treatment of gastrointestinal diseases in children. Due to severe response and spastic in  the muscles of the digestive tract is created during endoscopy,endoscopy is often face with difficult. The aim of this study is to evaluate peppermint impact in pyloric spasm in children undergo endoscopy.   Material and Methods: In this ...

The pentapeptide proctolin has been localized previously to the crustacean stomatogastric nervous system and shown to modulate the rhythmic activity of the pyloric network in the stomatogastric ganglion (STG) (Marder et al., 1986; Hooper and Marder, 1987). We have now identified a pair of modulatory proctolin-containing neurons (MPNs) that cause proctolin-like modulation of the pyloric rhythm. ...

INTRODUCTION Pyloric duplication is an extremely rare gastrointestinal tract malformation in neonates. This is the first case report of pyloric duplication in our country (Lithuania). CASE PRESENTATION We report the case of a 2-day-old Lithuanian girl who suffered from pyloric duplication mimicking an alternative common bile duct cyst or other intra-abdominal organs cysts. A laparotomy was pe...

Pyloric-gland type adenoma of the gallbladder is formed by proliferation of glands resembling pyloric glands, morphologically. No previous report has described the cellular phenotype and differentiation of pyloric-gland type adenoma of the gallbladder, using CD10 as a marker of proper biliary phenotype. Immunostainings were performed for mucin markers such as MUC5AC, human gastric mucin (HGM) f...
