Ileal pouch-related adenocarcinoma remains a rarity; thus, guidelines on treatment are currently lacking. We present this case of a 54-year-old man who underwent restorative proctocolectomy with stapled ileal pouch-anal anastomosis formation for familial adenomatous polyposis during the 1980s. Despite undergoing annual surveillance endoscopy, the patient was noted to be anaemic and passing fres...

1. Lipolytic and proteolytic activities and pH values were determined in secretions collected from innervated abomasal pouches and in abomasal contents from preruminant calves given liquid diets. 2. No lipolytic activity was detected in pouch secretions collected during 1 h after feeding, though lipolytic activity was present in abomasal contents; pepsin (EC 3.4.23.1) and renin (EC 3.4.23.4) we...

This study discusses the percentage of Hartmann’s pouch of gall bladder and whether the Hartmann’s Pouch is an anatomical variation or pathological presentation in North Coastal Andhra Pradesh. India. Knowledge of relevant anatomy is important for the safe execution of any operative procedure,specifically in laparoscopic cholecystectomy. It has been recognized since long that misinterpretation ...

The purpose of this study was to determine whether dexamethasone attenuates grain sorghum dust extract-induced increase in macromolecular efflux from the in situ hamster cheek pouch and, if so, whether this response is specific. By using intravital microscopy, we found that an aqueous extract of grain sorghum dust elicited significant, concentration-dependent leaky site formation and increase i...

INTRODUCTION In gout, monosodium urate (MSU) crystals deposit intra-articularly and cause painful arthritis. In the present study we tested the hypothesis that Transient Receptor Poten-tial Ankyrin 1 (TRPA1), an ion channel mediating nociceptive signals and neurogenic in-flammation, is involved in MSU crystal-induced responses in gout by utilizing three experi-mental murine models. METHODS Th...

BACKGROUND Hancornia speciosa Gomes (Apocynaceae), popularly known as "mangabeira," has been used in folk medicine to treat inflammatory disorders, hypertension, dermatitis, diabetes, liver diseases and gastric disorders. Although the ethnobotany indicates that its fruits can be used for the treatment of ulcers and inflammatory disorders, only few studies have been conducted to prove such biolo...

OBJECTIVE The authors compared clinical bowel function and complications of a low anterior resection with either a straight or colonic J pouch anastomosis. SUMMARY BACKGROUND DATA Urgency and frequent bowel movements after rectal resection with a low anastomosis have been related to the loss of rectal reservoir function. Reconstruction with a colonic J pouch possibly can obviate some of this ...

The cheek pouch of the Syrian hamster is an excellent model for the experimental study of oral carcinogenesis. The carcinogenic chemical 7,12-dimethylbenz[a]anthracene consistently produces epidermoid carcinomas in the cheek pouch of the Syrian hamster, giving rise to characteristic histopathological lesions in a time-dependent manner. We now present experimental evidence that c-Ki-ras mRNA can...

BACKGROUND AND METHODS The comparative benefits and drawbacks of straight coloanal anastomosis (CAA), colonic J-pouch and coloplasty anastomosis after anterior resection are uncertain. Studies published between 1986 and 2005 of colonic J-pouch versus transverse coloplasty or straight CAA were analysed. Endpoints included postoperative complications, and functional and physiological outcomes mea...

The digestive tract in workers of some species of the pseudomyrmecine ant genus Tetraponera is characterized by a conspicuous pear-shaped diverticulum at the transition between the midgut and the intestine, that so far has not been found in any other ant species. As this organ is filled with a mass of bacteria, we propose to designate it as a bacterial pouch. Its distal wall is formed by a thin...
