The number of MMC in the antrum was lower than that in the duodenum after the operation. The mean duration of MMC of the antrum, pylorus and duodenum was (49 2±10 5 ) min, (46 5±10 4 ) min and (45 9±10 0) min respectively.
The rate of HP infection in rural (85.5%), was higher in that of urban (36.6%), and positive rate of HP was more than 70% in different patients with peptic ulcer except pylorus ulcer (68.8%) and only 14.6% in controls.
In order to study the effect of a new surgical methodgastric and pyloric reconstruction after total gastrectomy on immune function of gastric carcinoma patients,serum IgA、IgG、IgM、CD4、CD8、NKL、L、IL-2、sIL-2R and INF-γ were determined in 0.5,1 year after operation.
Heterogenous distribution of peptide-containing nerve fibres within the circular muscle layer of the human pylorus
The narrow region of the circular muscle layer bordering the submucosa in the pylorus contained a rich supply of VIP, SP, ENK and CGRP immunoreactive fibres; VIP fibres were most prominent with less SP and ENK fibres and moderate amounts of CGRP.
In the acute situation, intravenous erythromycin may alleviate gastroparesis, but probably exerts little beneficial effect beyond the pylorus; parenteral metoclopramide may be tried, but, here again, convincing evidence of efficacy is lacking.
In patients for whom all medical therapy fails, other options that are tried at experienced centers include the injection of botulinum toxin into the pylorus, placement of a feeding jejunostomy, and/or placement of a gastric electrical stimulator.
Surgical resection in the form of pylorus-preserving pancreaticoduodenectomy remains the optimal solution in the attempt to clarify the diagnosis and offer treatment with low complication rates.
Parasitic fauna of the Atlantic spiny lumpsucker is represented by the larvae of Anisakis simplex that are located on the liver parenchyma and pyloric appendages.
in the pyloric caeca and intestines of the large-scaled gurnards is also the first report of the parasite in this fish species.
These peptide-containing nerve fibres were more dense than in the pyloric circular muscle, the longitudinal muscle layer and also the adjacent muscle layer.
NPY-immunoreactive fibres were sparsely distributed throughout the pyloric region.
These results suggest that the inner edge of the circular muscle, lying adjacent to the submucosa and densely innervated with peptidecontaining fibres, may be a characteristic feature of the human pyloric sphincter.
