Carmi syndrome comprises of EB (Epidermolysis Bullosa) and PA (pyloric atresia). We report the radiological finding of mucosal irregularity as seen in upper GI contrast study in the antral region and along the greater curvature in a case of this syndrome. This could act as a clinical tip off for the presence of Carmi syndrome in cases of a solitary PA. It is proposed that in such a case, the PA...

2. Swine pyloric juice also exhibited two proteolytic pH maxima, at pH values 1-6 and 2-6, which are lower than those of swine or human fundic extracts or of human gastric juice. 3. Crystalline swine pepsin can be separated into two components, one of which digested proteins with pH maxima close to those found with swine fundic mucosa and the other with maxima close to those found with pyloric ...

Acquired gastric outlet obstruction (GOO) during infancy beyond the neonatal period is a very rare condition when other congenital causes like infantile hypertrophic pyloric stenosis, antral diaphragm, pyloric atresia etc are excluded. We report an unusual case of 6 month old male child who presented with recurrent episode of vomiting not relieved by medication. On gastrograffin study there was...

The gastrin cells of the Japanese quail were studied histologically and immunocytochemically. Cells reacting with antiserum to gastrin (gastrin cells) were demonstrated by the peroxidase-labelled antibody method and showed brownish cytoplasm. They also were stained argyrophil by the Grimelius' silver method. Gastrin cells were found in the epithelium of the pyloric region and small intestine an...

THE gastric mucous membrane is described as being disposed in three regions, known as the cardiac, fundic, and pyloric. These regions, although distinguished from one another by definite microscopic characters, yet merge gradually the one into the other, so as to present no well-defined lines of demarcation. The actual extent of each region varies in different animals. It has not been sufficien...

In order to elucidate the proliferative behavior of the intestinal metaplasia around gastric cancer, the authors used both in vitro tritiated thymidine (3H-thymidine) autoradiography and in vivo bromodeoxyuridine (BrdUrd) immunohistochemistry for labeling the proliferative cells of the normal pyloric glands and metaplastic gastric glands. The results of the methods were comparable: The labeling...

Neuromodulatory inputs play a critical role in governing the expression of rhythmic motor output by the pyloric network in the crustacean stomatogastric ganglion (STG). When these inputs are removed by cutting the primarily afferent stomatogastric nerve (stn) to the STG, pyloric neurons rapidly lose their ability to burst spontaneously, and the network falls silent. By using extracellular motor...

Modulation of synaptic transmission is a major mechanism for the functional reconfiguration of neuronal circuits. Neurotransmitter release and, consequently, synaptic strength are regulated by intracellular Ca(2+) levels in presynaptic terminals. In identified neurons of the lobster pyloric network, we studied localized, voltage-induced Ca(2+) accumulation and its modulation in varicosities on ...

The accumulation of Cd, Pb, Zn, and Cu in the starfish Asterias rubens was studied in a Norwegian fjord characterized by a gradient of metal pollution in the sediments, ranging from very high metal concentrations at its head to much lower levels at its opening. The concentrations of metals in starfish from natural populations along the gradient (long-term accumulation) and in starfish that were...
