background: for a long time, intestinal parasite infections are among the major problems of public health in iran. our aim was epidemiological studies on the frequency of intestinal parasites in patients re­ferred to three hospitals in tehran during 2007-2008. methods : during 2007-2008, by simple random selection, 1000 stool samples were collected from mi­lad, hazrat-e-rasoul and shahid fahmid...

Gender is one of the factors influencing the intestinal microbial composition in mammals, but whether fish also have gender-specific intestinal microbial patterns remains unknown. In this decade, endocrine disrupting chemicals in surface and ground water of many areas and increasing observation of freshwater male fish displaying female sexual characteristics have been reported. Here we identifi...

Intestinal anastomosis is a surgical procedure that restores bowel continuity after surgical resection to treat intestinal malignancy, inflammation, or obstruction. Despite the routine nature of intestinal anastomosis procedures, the rate of complications is high. Standard visual inspection cannot distinguish the tissue subsurface and small changes in spectral characteristics of the tissue, so ...

Intestinal obstruction may be duo to various mechanical or functional reasons. Worms, especially Ascaris worms are one of the mechanical reasons of intestinal obstruction. Obstruction due to Taenia saginata is a rare phenomenon. Here we report a case of intestinal obstruction due to Taenia saginata infection in a 30 year-old male patient undergoing laparatomy with the diagnosis of intestinal ob...

Behçet's disease (BD) is a multisystem inflammatory disorder that presents as recurrent oral and genital ulcers in conjunction with other dermatological and ocular manifestations. The prevalence of BD is higher in Middle and East Asia than in Western countries. Intestinal BD is a specific subtype of BD, characterized by intestinal ulcers and associated gastrointestinal symptoms. Similar to infl...

1. The effects of several CYP3A substrates (alpha-naphthoflavone (alphaNF), terfenadine, midazolam, erythromycin) on nifedipine oxidation and testosterone 6beta-hydroxylation activities were investigated in hepatic and intestinal microsomes from mouse and human. 2. alphaNF (10 microM) and terfenadine (100 microM) inhibited nifedipine oxidation activities (at substrate concentration of 100 micro...

A 55-year-old woman was admitted to our hospital reporting of nausea, vomiting and anorexia. One month before admission, she had been diagnosed with lung cancer with intestinal metastasis. A CT scan confirmed intussusception due to intestinal metastasis and she underwent emergency laparoscopic surgery followed by resection of the primary lung cancer. Histopathological findings of the intestinal...

We investigated the prevalence and characteristics of intestinal alkaline phosphatase (ALP; EC 3.1.3.1) identified in human serum by cellulose acetate electrophoresis in 8% of fasting serum samples from hospital patients (n = 500) and in 35% of fasting serum samples from patients with diabetes mellitus (n = 106; not differentiated between types 1 and 2). The intestinal ALP electrophoretic band ...

Behçet's disease (BD) is a multi-systemic inflammatory disorder of an unknown etiology and shows a chronic recurrent clinical course. When the disease involves the alimentary tract, it is called intestinal BD because of its clinical importance. Intestinal BD is more frequently reported in East Asian countries than in Western or Middle Eastern countries. While any part of the gastrointestinal tr...

The normal immunoregulatory mechanisms that maintain homeostasis in the intestinal mucosa, despite continuous provocation by environmental antigens, are jeopardized in inflammatory bowel diseases. Although previous studies have suggested that intestinal intraepithelial lymphocytes prevent spontaneous intestinal inflammation, there is limited knowledge about the characteristics of regulatory cel...
