The effect of diethyl maleate administration on biliary phospholipid secretion was studied in male New Zealand rabbits. Bile flow was significantly enhanced during the first 40 min following i.p. injection of diethyl maleate at 3.2 mmol/kg body wt., after which it decreased progressively to values half those of the controls at 2 h of injection of the chemical. Bile acid secretion was not significantly modified during choleresis but was significantly reduced from 60 min of diethyl maleate administration onwards. A significant increase in biliary phospholipid secretion parallel to that occurring in bile flow was observed in diethyl maleate-treated rabbits. Our data confirm the uncoupling previously described for the rat between bile acid and phospholipid secretion into bile during diethyl maleate-induced choleresis.

UI	MeSH Term	Description	Entries
D008297	Male		Males
D008298	Maleates	Derivatives of maleic acid (the structural formula (COO-)-C
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.	Phosphatides,Phospholipid
D011817	Rabbits	A burrowing plant-eating mammal with hind limbs that are longer than its fore limbs. It belongs to the family Leporidae of the order Lagomorpha, and in contrast to hares, possesses 22 instead of 24 pairs of chromosomes.

D002756	Cholagogues and Choleretics	Gastrointestinal agents that stimulate the flow of bile into the duodenum (cholagogues) or stimulate the production of bile by the liver (choleretic).	Choleretics,Cholagogues,Cholagogues, Choleretics,Choleretics and Cholagogues,Hydrocholeretics
D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.	Animal,Metazoa,Animalia
D001646	Bile	An emulsifying agent produced in the LIVER and secreted into the DUODENUM. Its composition includes BILE ACIDS AND SALTS; CHOLESTEROL; and ELECTROLYTES. It aids DIGESTION of fats in the duodenum.	Biliary Sludge,Sludge, Biliary
D001647	Bile Acids and Salts	Steroid acids and salts. The primary bile acids are derived from cholesterol in the liver and usually conjugated with glycine or taurine. The secondary bile acids are further modified by bacteria in the intestine. They play an important role in the digestion and absorption of fat. They have also been used pharmacologically, especially in the treatment of gallstones.	Bile Acid,Bile Salt,Bile Salts,Bile Acids,Acid, Bile,Acids, Bile,Salt, Bile,Salts, Bile
