Mucosal alkaline phosphatase and bile lipids in the gallbladder in cholecystitis. 1983

E Kouroumalis, and D Hopwood, and P E Ross, and I A Bouchier

Histochemically, alkaline phosphatase was localised in epithelial brush-border and capillary endothelium of the lamina propria in 41 gallbladders studied. Three distinct patterns of the brush-border enzyme distribution were observed, namely, complete delineation, patchy localisation and a brush-border totally devoid of enzyme activity. Where no histochemical activity was found, biliary chenodeoxycholate was 50 per cent. higher than in cases of patchy distribution and twice as high as in cases with complete staining of the brush-border. Conversely, biliary cholate levels were significantly higher in completely stained cases. Biliary cholesterol was higher in the cases with no histochemical activity and this was reflected in a significantly higher lithogenic index. Significant quantities of cholesterol esters were found in bile from the focal activity group only. Total alkaline phosphatase activity assayed in gallbladders from 112 patients with cholecystitis and/or lithiasis showed that activity was significantly lower in patients with pigment stones than patients with cholecystitis and/or cholesterol stones. This activity was not related to biliary lipid composition in the 77 bile samples analysed. This evidence indicates that biliary lipid composition is associated with the histochemical distribution of alkaline phosphatase in gallbladder mucosa.

UI	MeSH Term	Description	Entries
D008055	Lipids	A generic term for fats and lipoids, the alcohol-ether-soluble constituents of protoplasm, which are insoluble in water. They comprise the fats, fatty oils, essential oils, waxes, phospholipids, glycolipids, sulfolipids, aminolipids, chromolipids (lipochromes), and fatty acids.

D008875	Middle Aged	An adult aged 45 - 64 years.	Middle Age
D009092	Mucous Membrane	An EPITHELIUM with MUCUS-secreting cells, such as GOBLET CELLS. It forms the lining of many body cavities, such as the DIGESTIVE TRACT, the RESPIRATORY TRACT, and the reproductive tract. Mucosa, rich in blood and lymph vessels, comprises an inner epithelium, a middle layer (lamina propria) of loose CONNECTIVE TISSUE, and an outer layer (muscularis mucosae) of SMOOTH MUSCLE CELLS that separates the mucosa from submucosa.

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.

D002764	Cholecystitis	Inflammation of the GALLBLADDER; generally caused by impairment of BILE flow, GALLSTONES in the BILIARY TRACT, infections, or other diseases.	Empyema, Gallbladder,Gallbladder Inflammation,Empyema, Gall Bladder,Gall Bladder Empyema,Gallbladder Empyema,Inflammation, Gallbladder
D002784	Cholesterol	The principal sterol of all higher animals, distributed in body tissues, especially the brain and spinal cord, and in animal fats and oils.	Epicholesterol
D002788	Cholesterol Esters	Fatty acid esters of cholesterol which constitute about two-thirds of the cholesterol in the plasma. The accumulation of cholesterol esters in the arterial intima is a characteristic feature of atherosclerosis.

D005704	Gallbladder	A storage reservoir for BILE secretion. Gallbladder allows the delivery of bile acids at a high concentration and in a controlled manner, via the CYSTIC DUCT to the DUODENUM, for degradation of dietary lipid.	Gallbladders
