Gastric mucosal phospholipids, and in particular those of the surface layer, play an important part in mucosal barrier function. This study examined whether the phospholipid composition of the full thickness gastric mucosa is changed in peptic ulcer disease and gastritis. The phospholipid composition of gastric mucosa from endoscopic biopsy specimens in 28 subjects (eight healthy controls, 12 patients with duodenal ulcer, and eight with chronic atrophic gastritis) was studied. In addition, the phospholipid composition of gastric mucosa was compared with that of duodenal mucosa in 10 patients with duodenal ulcer. As expected phosphatidylcholine and phosphatidylethanolamine prevailed in all three groups. Lysolecithin was the smallest component in the duodenal ulcer and chronic atrophic gastritis groups. The phosphatidylethanolamine value was higher in duodenal ulcer and lower in chronic atrophic gastritis compared with the control group. In chronic atrophic gastritis there was an appreciable amount of phosphatidylglycerol that was not present in patients with duodenal ulcer or in the control group. There was no significant difference in phospholipid composition between antral and duodenal sites in duodenal ulcer patients. In conclusion, the phospholipid composition of gastric mucosa changes in human gastrointestinal diseases but its relation to cellular functions needs further study.

D008875	Middle Aged	An adult aged 45 - 64 years.	Middle Age
D010743	Phospholipids	Lipids containing one or more phosphate groups, particularly those derived from either glycerol (phosphoglycerides see GLYCEROPHOSPHOLIPIDS) or sphingosine (SPHINGOLIPIDS). They are polar lipids that are of great importance for the structure and function of cell membranes and are the most abundant of membrane lipids, although not stored in large amounts in the system.

D011706	Pyloric Antrum	The region between the sharp indentation at the lower third of the STOMACH (incisura angularis) and the junction of the PYLORUS with the DUODENUM. Pyloric antral glands contain mucus-secreting cells and gastrin-secreting endocrine cells (G CELLS).

D002855	Chromatography, Thin Layer	Chromatography on thin layers of adsorbents rather than in columns. The adsorbent can be alumina, silica gel, silicates, charcoals, or cellulose.

D002908	Chronic Disease	Diseases which have one or more of the following characteristics: they are permanent, leave residual disability, are caused by nonreversible pathological alteration, require special training of the patient for rehabilitation, or may be expected to require a long period of supervision, observation, or care (Dictionary of Health Services Management, 2d ed). For epidemiological studies chronic disease often includes HEART DISEASES; STROKE; CANCER; and diabetes (DIABETES MELLITUS, TYPE 2).

D005753	Gastric Mucosa	Lining of the STOMACH, consisting of an inner EPITHELIUM, a middle LAMINA PROPRIA, and an outer MUSCULARIS MUCOSAE. The surface cells produce MUCUS that protects the stomach from attack by digestive acid and enzymes. When the epithelium invaginates into the LAMINA PROPRIA at various region of the stomach (CARDIA; GASTRIC FUNDUS; and PYLORUS), different tubular gastric glands are formed. These glands consist of cells that secrete mucus, enzymes, HYDROCHLORIC ACID, or hormones.

D005757	Gastritis, Atrophic	GASTRITIS with atrophy of the GASTRIC MUCOSA, the GASTRIC PARIETAL CELLS, and the mucosal glands leading to ACHLORHYDRIA. Atrophic gastritis usually progresses from chronic gastritis.	Atrophic Gastritides,Atrophic Gastritis,Gastritides, Atrophic
