Ischemia of the intestine may manifest with different clinical features, each one requiring a specific diag­ nosis and treatment approach. Early identification and treatment of acute mesenteric ischemia is cru­ cial to improve prognosis. For that purpose, early angiography followed by surgery or a direct laparo­ tomy in critically ill patients is warranted. Embolec­ tomy and bowel resection for...

Introduction Brominated flame retardants are widely used and increasingly detected in abiotic and biotic compartments globally. Tetrabromobisphenol, polybrominated diphenyl ethers (PBDEs) and hexabromocyclododecane (HBCD) are most ubiquitous. HBCD is the principle fire retardant in polystyrene foams that are used as insulation in the building industry and for upholstering furniture. Bioaccumula...

cation after surgical repair in children with esophageal atresia. The usual treat− ment is endoscopic dilatation. If this fails, reoperation is needed. A male infant presented with type 1 esophageal atresia [1]. A gastrostomy was performed on day 1 after birth, defi− nitive repair being delayed because of the long gap. Three months later an ileoceco− coloplasty was performed, the ileum being an...

Fundamental to the understanding and inter pretation of histochemical and chemical changes in the liver following partial hepatectomy (18, 21) is a knowledge of the behavior of the cells during the process of restoration or regeneration. Some of the changes in the liver of various species including rats, following extirpation of two-thirds of the liver, have been described (3, 7, 9, 15, 17). Th...

BACKGROUND: It is a common belief that a laparogoing laparoscopically assisted right hemicolecscopic procedure results in a shorter duration of tomy compared to the dog undergoing open right postoperative ileus compared with the equivalent hemicolectomy. This data does not support the open procedure. This study was undertaken to hypothesis that a laparoscopically assisted codetermine whether la...

Mammary tumors were induced in 50-day-old albino Sprague-Dawley rats by a single feeding of 20 mg. of 7,[email protected][a]anthracene. Adrenalectomy-ovariec tomy and hypophysectomy performed within 10-20 days after tumors were first de tected resulted in tumor regression in all the animals. Estrogen administration re activated tumor growth after adrenalectomy-ovariectomy but not after hypophy s...
