extract of echinops persicus is traditionally used for a long time in iran for treatment of cough and constipation. this extract is produced by activity of bug (situphilus spp.) on the plant. we documented its anti-tussive effect in rats in our previous study.the aim of this study was to assess the anti-ulcer effect of echinops persicus in an animal model. in this study we evaluated anti-ulcer ...

A 4.5-year-old Holstein-Friesian cow underwent surgery because of left abomasal displacement. Intra-operative palpation of the pyloric region revealed a phytobezoar. The abomasum containing the phytobezoar was exteriorized, and an incision was made directly over the mass in the region of the greater curvature of the pyloric part of the abomasum.

Administration of pentagastrin in depot form to 20 pregnant bitches produced pyloric hypertrophy in about 28% and gastroduodenal ulceration in about 16% of their pups. The two lesions were not necessarily found in the same individuals. Histological appearances of the pylorus in affected pups closely resembled those of human infantile pyloric stenosis.

Plasma concentrations of gastrin, somatostatin, neurotensin, and enteroglucagon were measured by radioimmunoassay in normal 30and 45-day-old neonates and age-matched infants with confirmed idiopathic hypertrophic pyloric stenosis. Plasma gastrin and somatostatin concentrations were similar in both groups, whereas neurotensin and enteroglucagon were significantly lower in the pyloric stenosis gr...

Gastric biopsies from 35 infants with hypertrophic pyloric stenosis have been assessed for histological features of gastritis. No erosions were found, and there was no excess cellular infiltration of the lamina propria compared with a control group. Fresh haemorrhage into the lamina propria was frequent in both pyloric stenosis and control sections.

Periodic current forcing was used to investigate the intrinsic dynamics of a small group of electrically coupled neurons in the pyloric central pattern generator (CPG) of the lobster. This group contains three neurons, namely the two pyloric dilator (PD) motoneurons and the anterior burster (AB) interneuron. Intracellular current injection, using sinusoidal waveforms of varying amplitude and fr...
