|---|---|
| peptic cell | <pathology> Cells of the basal part of the gastric glands of the stomach. They contain extensive rough endoplasmic reticulum and zymogen granules and secrete pepsinogen, the inactive precursor of pepsin and rennin. (18 Nov 1997) |
| peptic digestion | That part of digestion, chiefly of the proteins, carried on in the stomach by the enzymes of the gastric juice. Synonym: peptic digestion. (05 Mar 2000) |
| peptic gland | A pepsin-secreting gland. See: gastric glands. (05 Mar 2000) |
| peptic ulcer | <gastroenterology> An ulcer in the wall of the stomach or duodenum resulting from the digestive action of the gastric juice on the mucous membrane when the latter is rendered susceptible to its action. (13 Nov 1997) |
| peptic ulcer perforation | Penetration of a peptic ulcer through the stomach wall. May be free, i.e., at a point where the stomach wall faces a real or potential space,, or confined, i.e., at a point where the stomach wall is defended by contiguous or adjacent structures, such as the pancreas. (12 Dec 1998) |
| peptichemio | <chemical> A mixture of six synthetic oligopeptides, each containing melphalan. It is used as a broad-spectrum antineoplastic due to its alkylating and antimetabolic actions but, is toxic to bone marrow, gastrointestinal system and vasculature. Pharmacological action: antimetabolites, antineoplastic, antineoplastic agent, alkylating. Chemical name: Peptichemio (12 Dec 1998) |

| ulcer, peptic | A peptic ulcer is a hole in the lining of the stomach, duodenum, or oesophagus. A peptic ulcer of the stomach is called a gastric ulcer, an ulcer of the duodenum is a duodenal ulcer, and a peptic ulcer of the oesophagus is an oesophageal ulcer. A peptic ulcer occurs when the lining of these organs is corroded by the acidic digestive juices which are secreted by the stomach cells. Peptic ulcer disease is common, affecting millions of americans yearly. The medical cost of treating peptic ulcer and its complications runs in the billions of dollars annually in the u.s. Recent medical advances have increased our understanding of ulcer formation. Improved and expanded treatment options are now available. (12 Dec 1998) |
