Ingestion of diets containing Aroclor 1254, a mixture of polychlorinated biphenyls, for 2 years led to a dose-related increase in the incidence of focal lesions in the glandular stomachs of male and female F344 rats. The incidence of stomach lesions was 6% in control specimens and in speci mens from rats fed a diet containing 25, 50, or 100 ppm Aroclor 1254, the incidences of stomach lesions we...

pyoderma gangrenosum is a rare inflammatory skin condition characterized by progressive and recurrent skin ulceration of destructive course. It is usually associated with rheumatoid arthritis, paraproteinemia, myeloproliferative diseases and inflammatory bowel diseases, especially non-specific ulcerative proctocolitis. In these situations, skin lesions are described as concurrent with the intes...

PURPOSE Histological study of vascularization between a cecal pedicle flap and the testicle of Wistar rats. METHODS Fifty-three rats were studied. G1: submitted to celiotomy (a), mobilization of the right testicle (RT) to the abdomen (b), cecal flap suture to the RT (d) and cavity closure. G1: procedures a, b and d and fixation of RT into abdomen. G3: procedures a, b and d, exposition of RT t...

TRACHEO-OESOPHAGEAL fistula and oesophageal atresia (TOF) duodenal atresia, anorectal anomaly and exomphalos are known to have a significant association with renal abnormalities. 1-4 The incidence of the association varies depending on the primary gastrointestinal condition and the reported series but is sufficiently common in all to merit consideration of the routine investigation of neonates ...

Early detection of colonic polyps can prevent up to 90% of colorectal cancer deaths. Conventional colonoscopy readily detects the majority of premalignant lesions, which exhibit raised morphology. However, lesions that are flat and depressed are often undetected using this method. Therefore, there is a need for molecular-based contrast agents to improve detection rates over conventional colonos...

  Background : Approach to the small intestine has been difficult even with newer methods. Double-balloon enteroscopy (DBE) has been created for diagnostic and therapeutic interventions in diseases of the small intestine. Small intestinal diseases have different etiologies in each country. The DBE has been introduced in recent years in Iran. Our aim was to study the indications and results of D...
