Monkeys are important experimental models for investigating human diseases. The aim of this study was to survey the alimentary tract parasites among imported vervet monkeys (Cercopithecus aethiops) to Iran. Fecal samples were collected from 40 vervets imported from Tanzania to Razi Vaccine and Serum Research Institute of Iran. Fecal samples were assessed by direct smear and Telman sedimentation...

Many surgical procedures are used to restore the defect of the alimentary tract after cervical oesophagectomy. We present a case of a 69-year old woman, affected by a G2 squamous cell carcinoma of retro-cricodeal hypopharynx extend to the cervical oesopaghus. She underwent a direct reconstruction with a direct trans-oral anastomosis by a mechanical device and without any interposition. No posto...

Cytochrome P-450 (P450) enzymes in the mucosa of the alimentary tract may be involved in the activation and/or inactivation of ingested xenobiotics and procarcinogens. Since the multiple P450 enzymes have overlapping substrate specificities and, in some cases, similar antigenic determinants, definitive identification of P450 genes that are expressed in various tissues requires molecular analysi...

BACKGROUND Widely considered probiotic organisms, Bifidobacteria are common inhabitants of the alimentary tract of animals including insects. Bifidobacteria identified from the honey bee are found in larval guts and throughout the alimentary tract, but attain their greatest abundance in the adult hind gut. To further understand the role of Bifidobacteria in honey bees, we sequenced two strains ...

(Pp. xiii + 411; figs. 60. 60s.) London: William Heinemann Medical Books, 1963. THE appearance of this book is an important event. There has not been for many years a standard British textbook of gastroenterology, and recent attempts to supply one have not been so successful as one could have wished. The authoritative and massive three-volume work of Bockus is the stand-by of every gastroentero...

Duplications of the alimentary tract are rare congenital malformations and may be found anywhere along the alimentary tract. Their importance lies in the fact that they readily mimic other surgical disease processes and may result in significant morbidity if left untreated. We report a case of ileal duplication with heterotopic gastric mucosa presenting with melena and peptic ulcer perforation ...
