OBJECTIVE To determine the comparative efficacy of selective decontamination of the digestive tract in critically ill surgical and medical patients, and in selected subgroups of surgical patients with pancreatitis, major burn injury, and those undergoing major elective surgery and transplantation. DATA SOURCES The MEDLINE database was searched from January 1966 to December 1996 using the term...

A strain of Bacillus licheniformis, established in the digestive tract of gnotobiotic mice, inhibited the subsequent establishment of a Clostridium perfringens strain ingested by the animals. This inhibitory effect depended on the in vivo production by B. licheniformis of an antibiotic substance having a number of the characteristics of bacitracin. If C. perfringens was the first to become esta...

A method based on the use of the bacterial luciferase genes was developed in order to investigate Lactococcus lactis gene expression in the mouse digestive tract. Germfree mice were monoassociated with different strains containing transcriptional fusions of promoters with the luciferase genes. Our results demonstrate that this method is readily applicable to the study of promoter strength and p...

Short-term fate of dietary dieldrin in the digestive tract of fishes is poorly known. Studies of the uptake, distribution, and elimination of chlorinated hydrocarbons have suggested that uptake or degradation is rapid in the intestine (GROSS 1969; MACEK et al. 1970; GRZENDA et al. 1970, 1971). The present study was designed to determine the short-term fate of a single oral dose of dieldrin in t...

To the Editor: Fish bone is a kind of common ingested foreign body. In most cases, it may pass through the gastrointestinal tract or retain upper digestive tract such as the oral cavity, esophagus.[1] However, ascending colon perforation by huge fish body is rare, which can cause several complications.[2] There are only few case of colon perforation by foreign body in the literature.[3] Here, w...

OBJECTIVE We wanted to report on our experience with modified radiology-guided percutaneous gastrostomy (MRPG) without endoscopic or nasogastric access for treating patients with complete obstruction of the upper digestive tract. MATERIALS AND METHODS Fourteen oncology patients (13 had hypopharyngeal cancer and 1 had upper esophageal cancer) with complete obstruction of the upper digestive tr...

UNLABELLED AIR-FILLED CYSTS: Pneumatosis cystoides intestinalis (PCI) is a benign air-filled cystic formation lying in submucosal or subserous digestive tissue. PCI has been reported all along the digestive tract. CLINICAL SIGNS Manifestations of PCI vary greatly. Some cases are asymptomatic, while others are revealed by abdominal pain or pneumoperitoneum. Outcome is usually favorable. EXPL...

DNA amplification by the polymerase chain reaction (PCR) was applied in the investigation of the presence of Leishmania (Kinetoplastida: Trypanosomatidae) parasites in single phlebotomine sandflies. Three phlebotomine/parasite pairs were used: Lutzomyia longipalpis/Leishmania chagasi, Lutzomyia migonei/Leishmania amazonensis and Lutzomyia migonei/Leishmania braziliensis, all of them incriminate...

PETRINEC, Z., S. NEJEDLI, S. KUŽIR, A. OPAČAK: Mucosubstances of the digestive tract mucosa in northern pike (Esox lucius L.) and european catfish (Silurus glanis L.). Vet. arhiv 75, 317-327, 2005. ABSTRACT The distribution and quality of mucosubstances in the digestive tract of pike (Esox lucius) and catfish (Silurus glanis) is described. The digestive tract of pike and catfish is short, in ac...

However, the particularity of the alimentary track restricts the utilization of the current available examine techniques. The upper gastrointestinal tract can be examined by Gastroscopy. The bottom 2 meters makes up the colon and rectum, and can be examined by Colonoscopy. In between, lays the rest of the digestive tract, which is the small intestine characterised by being very long (average 7 ...
