bile pigment

n.

Any of the coloring materials in the bile derived from porphyrins, such as bilirubin.

bile

a clear yellow, orange or green fluid produced by the liver. It is concentrated and stored in the gallbladder, and is poured into the small intestine via the bile ducts when needed for digestion. Bile helps in alkalinizing the intestinal contents and plays a role in the digestion and absorption of fat; its chief constitutents are conjugated bile salts, cholesterol, phospholipid, bilirubin and electrolytes. See also bile duct, biliary.

bile acids

steroid acids derived from cholesterol; classified as primary, those synthesized in the liver, e.g. cholic and chenodeoxycholic acid, or secondary, those produced from primary bile acids by intestinal bacteria and returned to the liver by enterohepatic circulation, e.g. deoxycholic and lithocholic acid.

bile acid assay

are used in the diagnosis of liver disease and portacaval shunts when there are increased levels in the blood.

bile lake

bile duct obstruction may cause distention and rupture of biliary canaliculi. Small bile lakes result causing focal hepatic necrosis.

bile passages

bile canaliculi drain into bile ductules and interlobular ducts. These unite to form a series of hepatic ducts which carry the bile to the porta where they unite to form the common hepatic duct. This duct receives a cystic duct from the gallbladder (absent in the horse) and thence becomes the bile duct.

bile peritonitis

leakage of bile from the common bile duct or gallbladder may occur as a result of trauma, including perforation during percutaneous needle biopsy of the liver, and (rarely) erosion from biliary calculi. A chemical peritonitis results and may be fatal unless surgical repair is accomplished.

bile pigment

any one of the coloring matters of the bile; they are bilirubin, biliverdin, bilifuscin, biliprasin, choleprasin, bilihumin and bilicyanin. See also urobilinogen, stercobilin.

bile pleuritis

inflammation of the pleura resulting from perforating thoracic trauma with hepatodiaphragmatic fistula or iatrogenically from percutaneous liver biopsy techniques.

bile reflux

usually refers to movement of bile from the duodenum into the stomach where it may alter the gastric mucosal barrier causing gastritis and ulceration.

bile salts

see taurocholate, chenodeoxycholic acid, glycocholic acid.

white bile

1. bile containing much mucin.

2. bile trapped in obstructed system for a long period and from which pigments have been resorbed.

2. a stain or dyestuff.

3. a paintlike medicinal preparation applied to the skin.

abnutzen pigment

see lipofuscin.

bile pigment

any one of the coloring matters of the bile, derived from heme, including bilirubin, biliverdin, etc.

blood pigment

any one of the pigments derived from hemoglobin, including heme, hematoidin, etc.

pigment cells

see melanocyte.

pigment-enhancing media

formulated to promote the production of pigment by some bacteria, such as Pseudomonas aeruginosa and Rhodococcus equi, to aid in identification.

pigment genes

genes for each of the coat colors, e.g. white gene, black gene, orange gene.

respiratory p's

substances, e.g. hemoglobin, myoglobin or cytochromes, which take part in the oxidative processes of the animal body.
