an obstructed inguinal hernia is a common surgical emergency, which presents with a variety of contents like the small intestine, omentum, and colon. intestinal knotting is a rare entity encountered in surgical practice; it occurs when one coil of intestine wraps around the other and eventually leads to complications such as intestinal obstruction, ischemia, and gangrene. both conditions are co...

background: blastocystis  is a zoonotic protozoan parasite habit in intestinal tract of humans and wide range of animals. because of the mysterious nature and unknown or less-known aspects of blastocystis, comprehensive information about epidemiology of this parasite is not available. the objective of this study was to investigate the available parasitology studies during the last decade in ira...

background: intestinal parasites of humans are important health problems of most communities, especially those situated in tropical and subtropical areas. this study was carried out in rural population of mazandaran province, northern iran, during 2004-2005, with the purpose of achieving a better understanding of the distribution of intestinal protozoan parasites in this province. methods: a to...

Objective(s): Intestinal ischemia-reperfusion is a major problem, which may lead to multiorgan failure and death. The aim of this study was to evaluate the protective effects of dexmedetomidine on cell proliferation, antioxidant system, cell death, and structural integrity in intestinal injury induced by ischemia-reperfusion in rats. Materials and Methods: Animals were randomized into three gro...

Introduction: As a congenital and genetically related disease, many single nucleotide polymorphisms (SNPs) have been reported to be associated with the risk of HSCR. Our previous research showed that SNP rs2439302 (NRG1) interacted rs2435357 (RET) increase HSCR development. However, underlying molecular mechanism is still not well understood. Methods: were genotyped in 470 cases. The expression...

SUMMARY From April L 989 to March 1989 !here were 13 patients with small intestinal volvulus 23%, or all palients operated for small intestinal obstruction.All were male, age between 6 to 75, without any history of abdominal operation. Mortality was 38, 5% and morbidity included, intraabdominal abscesses, recurrent obstruction and wound infection were observed. Being the 3rd cause of intestin...

The enteric nervous system (ENS), the intrinsic innervation of the gastrointestinal tract, is an essential component of the gut neuromusculature and controls many aspects of gut function, including coordinated muscular peristalsis. The ENS is entirely derived from neural crest cells (NCC) which undergo a number of key processes, including extensive migration into and along the gut, proliferatio...

Loss of Endothelin-3/Endothelin receptor B (EDNRB) signaling leads to aganglionosis of the distal gut (Hirschsprung's disease), but it is unclear whether it is required primarily for neural crest progenitor maintenance or migration. Ednrb-deficient gut neural crest stem cells (NCSCs) were reduced to 40% of wild-type levels by embryonic day 12.5 (E12.5), but no further depletion of NCSCs was sub...
