duplications of gastrointestinal tract are congenital anomalies found in about 0.2% of all children. these include the rare gastric duplication. we present such a cyst in a 14 years old girl with gastric outlet obstruction. she was found to have a noncommunicating antral duplication cyst .the cyst was managed by cystectomy and marsupialization. microscopically the duplication cyst contained a m...

cutis laxa (cl) is a rare congenital and acquired disorder characterized by loose and redundant skin with reduced elasticity. three types of congenital cutis laxa have been recognized. other findings are pulmonary emphysema, bronchiectasia, hernia and diverticulosis. we describe a female neonate involved by cutis laxa syndrome and a positive family history. we focus on the radiologic findings o...

MANY of our research studies on dogs have required the repeated removal of large liver samples which must be processed immediately for biochemical or other studies. A simplified technique has been used. The tip of one of the lobes of the liver is gently grasped with a sponge (Fig. 1a). A 0 cotton ligature is placed as far back as is necessary to obtain the required size biopsy. The ligature is ...

Umbilical granulomas are common inflammatory reactions to the resolving umbilical stump. The double-ligature technique is simple to perform and provides good cosmetic and functional results with only minor complications. The granuloma becomes necrotic and drops off within seven to 14 days. The double-ligature is a preferable alternative to multiple topical applications of silver nitrate for the...

 The endocrine cells of Salmo trutta macrostigma stomach and pyloric caeca have been investigated using immunohistochemical techniques. 8 antisera were tested and 6 of them were detected in the endocrine cells serotonin, somatostatin, substance P, galanin, CCK and neuropeptide Y. These immunoreactive cells are described for the first time in the stomach and pyloric caeaca of Salmo trut...

The most common cause of gastric outlet obstruction in neonates and infants is hypertrophic pyloric stenosis. Pyloric web as a cause of gastric outlet obstruction is relatively rare in children and presents with non bilious vomiting, abdominal pain and failure to thrive. The onset of symptoms is usually late with nonspecific symptoms like vomiting and failure to thrive that seems to be due to n...

We report a case of recurrent gastritis with pyloric stenosis and cholangitis due to a rare variation in bile duct anatomy. A 72-year-old female patient showed recurrent gastral ulcers and biliary colic with cholangitis caused by gallstones in the main bile duct with an ectopic orifice in the prepyloric region and concurrent inflammatory pyloric stenosis. After temporarily successful endoscopic...

Different Shaker family alpha-subunit genes generate distinct voltage-dependent K+ currents when expressed in heterologous expression systems. Thus it generally is believed that diverse neuronal K+ current phenotypes arise, in part, from differences in Shaker family gene expression among neurons. It is difficult to evaluate the extent to which differential Shaker family gene expression contribu...

The amines dopamine (DA), serotonin (5-HT), and octopamine (Oct) each elicit a distinctive motor pattern from a quiescent pyloric network in the lobster stomatogastric ganglion (STG). We previously have demonstrated that these amines alter the synaptic strength at multiple, distributed sites within the pyloric network that could contribute to the amine-induced motor patterns. Here, we examined ...
