In an effort to reduce carcass contamination and consequent reprocessing, market-age broilers are often subjected to feed withdrawal (FW) before processing to reduce intestinal content and intestinal ruptures during processing. However, little is known regarding the effects of FW on mucus content and intestinal morphology. Therefore, 2 experiments were conducted to determine the effects of FW o...

background: parasitic diseases are among the most important problems of many countries in the world, especially developing ones. since various parts of iran have different types of weather, jobs and people, different and separate epidemiological studies for each province will be necessary. we have scarce information on the epidemiology of intestinal parasites in tribal regions of khuzestan prov...

introduction ingestion of foreign bodies has been previously reported in some patients with schizophrenia. this behavior may be a manifestation of delusional beliefs or a response to command hallucinations and can lead to severe complications. case presentation this paper reports a patient with schizophrenia who, as a manifestation of his illness, ingested a metallic skewer to kill ademon insid...

in order to evaluate the results of abdominal radiation plus chemotherapy in cases with stage ii and iii of immunoproliferative small intestinal disease in comparison to chemotherapy alone, fifty-one patients referred to shiraz university of medical sciences' affiliated hospitals were studied between 1980 and 1994. out of them 38 patients who had an abdominal mass were gathered into two gr...

Oral sulfasalazine (SASP) is now used clinically as a probe substrate of a breast cancer resistance protein (BCRP) activity; however the intestinal absorption characteristics of SASP are not well understood. The purpose of this study was to clarify the characteristics of SASP transport in the mouse intestine. The everted ileum was incubated with SASP in the absence or presence of the Bcrp inhib...

BACKGROUND Cryptosporidium is known as an opportunist disease-causing agent in man in recent decades. It causes diarrhea and intestinal disorders in the immune deficit and immune competent individuals. This study was aimed to investigate the clinical characteristics of HIV/AIDS patients with cryptosporidiosis infection. METHODS This cross-sectional descriptive study was performed on 53 HIV/AI...

Enterocytozoon was 1st described in 1985, in an AIDS patient with intestinal malabsorption and diarrhea. Since then, additional cases of infection with this organism have been observed, but only in individuals with AIDS and malabsorption. Intestinal tissue biopsies were obtained from a 45-year-old man prior to AIDS diagnosis, again nine months later and then at autopsy two months later. When th...

The digestive physiology of the germ-free animal has a number of characteristics (cecal hypertrophy, slower small intestine cell renewal, slower gastric emptying and intestinal transit) which distinguish it from that of the conventional animal. If the germ-free model is to be used to determine the role of gastrointestinal microflora in the nutrition of the conventional animal, it is essential t...

Fecal samples of 60 turkey poults that showed chronic progressive symptoms like unthriftiness, loss ofweight, diarrhea were collected from the most rural areas with high rate of turkey population in north andwest part of country for intestinal protozoan parasites. According to the morphological characteristics, likeshape, presence or absence of micropyle, and/or polar granule, the 5 different t...

Although endogenous CO2 hydration and serosal HCO3- are both known to contribute to the high rates of intestinal HCO3- secretion important to marine fish osmoregulation, the basolateral step by which transepithelial HCO3- secretion is accomplished has received little attention. Isolated intestine HCO3- secretion rates, transepithelial potential (TEP) and conductance were found to be dependent o...
