this experiment was conducted to determine the effects of dietary myrtle essential oil on small intestinal morphology and microbiology of broiler chickens. two hundred day-old broiler chickens (ross 308) were allocated to 5 treatments, 4 replications with a completely randomized design. the diets were supplemented with: no myrtle essential oil (control), each of myrtle essential oil at levels o...
A 71-year-old man who had small cell lung cancer was referred to our institution. Before starting chemotherapy, anemia progressed and stool examination was positive for occult blood. An abdominal computed tomography scan with contrast medium enhancement of the gastrointestinal tract disclosed a small intestinal tumor. Histological examination after the surgery confirmed that the tumor was metas...
Mouse inbred strains B10.O20 and O20 were used to study the genetics of susceptibility to small intestinal cancer. Strain B10.O20 is susceptible to tumors of the small intestine induced by a transplacental treatment with the carcinogen N-ethyl-N-nitrosourea on day 18 of gestation, whereas strain O20 is completely resistant. F1 hybrid mice are also completely resistant, indicating that homozygos...
Mouse inbred strains B10.O20 and O20 were used to study the genetics of susceptibility to small intestinal cancer. Strain B10.O20 is susceptible to tumors of the small intestine induced by a transplacental treatment with the carcinogen N-ethyl-/V-nitrosourea on day 18 of gestation, whereas strain O20 is completely resistant. F, hybrid mice are also completely resistant, indicating that homozygo...
US28 is a constitutively active chemokine receptor encoded by CMV (also referred to as human herpesvirus 5), a highly prevalent human virus that infects a broad spectrum of cells, including intestinal epithelial cells (IECs). To study the role of US28 in vivo, we created transgenic mice (VS28 mice) in which US28 expression was targeted to IECs. Expression of US28 was detected in all IECs of the...
Inherited colorectal cancer syndromes in humans exhibit regional specificity for tumor formation. By using mice with germline mutations in the adenomatous polyposis coli gene (Apc) and/or DNA mismatch repair genes, we have analyzed the genetic control of tumor regionality in the mouse small intestine. In C57BL/6 mice heterozygous for the Apc multiple intestinal neoplasia mutation (Apc(Min)), in...
Background: Since the treatment of meconium ileus is very different from other types of intestinal obstruction, it is very important to distinguish these two entities. The aim of this study was to assess sonographic findings to differentiate meconium ileus from other types of obstruction. Methods: This study was performed in Dr. Sheikh and Akbar hospitals, Mashhad Medical University of Science...
Background : Mechanical obstruction is the most common surgical disease of the small intestine , which can be potentially fatal . However appendicitis is very rare cause of intestinal obstruction and is usually . In rare cases of appendicitis, symptoms of small intestine obstruction can be more predominant than the appendicitis symptoms . This may lead to delayed diagnosis of appendicitis and...
