Both bile acids and bile alcohols, a subclass of steroids, are made from cholesterol as its major end metabolites by the liver of vertebrates. Their conjugates are the major constituents of the bile and possess a special function as an aid to intestinal lipid digestion and absorption. The most common naturally occurring bile acids in mammals, birds, most snakes, and various teleostean fishes, a...

Rats equipped with biliary, duodenal, and vena cava cannulae and supplemented with Na taurocholate received 4 hour infusions of gastrointestinal hormones. Boots secretin increased bile flow by 63% and bile acid, cholesterol, and phospholipid output by 75, 96, and 73% respectively. This stimulatory effect on bile flow and bile acid secretion was observed also in the four hour postinfusion period...

AIMS To investigate the fibrinolytic activity of normal and calculous human bile. METHODS Fibrinolytic properties of the biliary tract were studied in patients with gall bladder stones (n = 7) compared with acalculous gall bladders (n = 8). RESULTS Bile plasminogen activating activity was detected in a wide range in both groups (calculous bile median 0.35 IU/ml; range: 0.06-6.59, versus nor...

The influence of bile acids on adenosine 3',5'-phosphate-induced intestinal secretion was studied in mice. Bile flow was stopped by ligation of the common bile duct, and secretion was induced in ligated loops of the small intestine. The decrease of bile led to inhibition of hypersecretion after challenge with heat-labile enterotoxins from Vibrio cholerae and Escherichia coli, as well as with pr...

Under uniform diet conditions the normal bile fistula dog will eliminate pretty constant amounts of cholesterol-about 0.5 to 1.0 mg. cholesterol per kilo per 24 hours. Diets rich in cholesterol (egg yolk) will raise the cholesterol output in the bile but compared to the diet intake (1.5 gm. cholesterol) the output increase in the bile is trivial (5-15 mg.). Calves' brains in the diet are inert....

As early as 1926 Mellanby (1) was able to show that introduction of bile into the duodenum of anesthetized cats produces a copious flow of pancreatic juice. In conscious dogs, Ivy & Lueth (2) reported, bile is only a weak stimulant of pancreatic secretion. Diversion of bile from the duodenum, however, did not influence pancreatic volume secretion stimulated by a meal (3,4). Moreover, Thomas & C...

Haemobilia is a rare cause of unrecognized gastrointestinal bleeding and is hard to diagnose. Through the present case report we aim to corroborate magnetic resonance relevance in the evaluation of biliary system and bile features, investigating on its role in patients with acute biliary diseases. We report a case of a Caucasian 48-year-old man who was admitted due to abdominal pain and fever. ...

BACKGROUND Traditional Persian medicine (TPM) is based on humors theory. Temperament or mizaj is the result of a combination of four fundamental humors called blood, phlegm, yellow bile, and black bile. Like any other diseases, acne is the result of humoral imbalance. Acne is a highly prevalent dermatological problem, which has both physical and psychological effects on patients. The aim of thi...

BACKGROUND Training and experience of the surgical team are fundamental for the safety and success of complex surgical procedures, such as laparoscopic common bile duct exploration. METHODS We describe an inert, simple, very low-cost, and readily available training model. Created using a "black box" and basic medical and surgical material, it allows training in the fundamental steps necessary...

Five functions relating to the bile excretion were recorded simultaneously; that is, pressures of the gall bladder and the common bile duct, amount of bile discharged into the duodenum, spike discharges of the sphincter of Oddi and the duodenal wall. In the observation of motility of the sphincter of Oddi, we used the rubber tube passing through it. Bile flow into the duodenum was continuously ...
