| orphan products | Drugs, biologicals, and medical devices (including diagnostic in vitro tests) that may be useful in common or rare diseases but which are not considered commercially viable. Synonym: orphan drugs. (05 Mar 2000) |
| orphan viruses | Virus's, such as the enteric orphan virus's, which when originally found were not specifically associated with disease; a number of these have since been shown to be pathogenic. (05 Mar 2000) |
| tablets, enteric-coated | Tablets coated with material that delays release of the medication until after they leave the stomach. (12 Dec 1998) |
| enteric | Relating to the intestine. (18 Nov 1997) |
| enteric bacteria | A large group of Gram negative rod-shaped bacteria characterised by a facultatively aerobic metabolism. Many of them are commonly found in the intestines of animals. (09 Oct 1997) |
| enteric-coated | A term designating a special coating applied to tablets or capsules which prevents release and absorption of their contents until they reach the intestines. (18 Nov 1997) |
| enteric coated tablet | An oral dosage form in which a tablet is coated with a material to prevent or minimise dissolution in the stomach but allow dissolution in the small intestine. This type of formulation either protects the stomach from a potentially irritating drug (e.g., aspirin) or protects the drug (e.g., erythromycin) from partial degradation in the acidic environment of the stomach. (05 Mar 2000) |
| enteric coating | A coating put on a capsule or pill so that it does not dissolve until itreaches the small intestine. (09 Oct 1997) |
| enteric fever | <disease, microbiology> An infectious febrile illness usually spread by contamination of food, milk or water supplies with Salmonella typhi, either directly by sewage, indirectly by flies or by faulty personal hygiene. There are less than 600 cases per year in the us. Asymptomatic carriers harbor the organism in their gallbladder and excrete it in their stools for years. Average incubation time is 10-14 days. Fever, diarrhoeal stools (often bloody), abdominal pain, malaise and a rose coloured rash on the upper abdomen are seen. Severe cases may progress to delirium and obtundation. Complications include glomerulonephritis. Treatment includes intravenous fluids and antibiotics (chloramphenicol or ampicillin). Vaccines are recommended for travel to endemic areas. (27 Sep 1997) |
| enteric nervous system | Two ganglionated neural plexuses in the gut wall which form one of the three major divisions of the autonomic nervous system. The enteric nervous system innervates the gastrointestinal tract, the pancreas, and the gallbladder. It contains sensory neurons, interneurons, and motor neurons. Thus the circuitry can autonomously sense the tension and the chemical environment in the gut and regulate blood vessel tone, motility, secretions, and fluid transport. The system is itself governed by the central nervous system and receives both parasympathetic and sympathetic innervation. (12 Dec 1998) |
| enteric organism | A microorganism that lives in the intestines. (09 Oct 1997) |
| enteric plexus | The autonomic plexus in the wall of the intestine; it consists of three parts, submucosal, myenteric, and subserosal; ganglionic cells are scattered through the myenteric and submucosal plexus. Synonym: plexus entericus. (05 Mar 2000) |
| enteric tuberculosis | A complication of cavitary pulmonary tuberculosis usually resulting from expectoration and swallowing of bacilli that then infect areas of the digestive tract where there is relative stasis or abundant lymphoid tissue. See: tuberculous enteritis. (05 Mar 2000) |
| enteric viruses | Virus's of the genus Enterovirus. (05 Mar 2000) |
