Cyclobutyrol is a drug used in bile therapy. Cyclobutyrol (CB) is a choleretic agent which also inhibits biliary lipids secretion.
Bile, or gall, is a yellow-green fluid produced by the liver of most vertebrates that aids the digestion of lipids in the small intestine. In humans, bile is primarily composed of water, produced continuously by the liver, and stored and concentrated in the gallbladder. After eating, this stored bile is discharged into the first section of the small intestine.
In vertebrates, the gallbladder, also known as the cholecyst, is a small hollow organ where bile is stored and concentrated before it is released into the small intestine. In humans, the pear-shaped gallbladder lies beneath the liver, although the structure and position of the gallbladder can vary significantly among animal species. It receives and stores bile, produced by the liver, via the common hepatic duct, and releases it via the common bile duct into the duodenum, where the bile helps in the digestion of fats.
A gallstone is a stone formed within the gallbladder from precipitated bile components. The term cholelithiasis may refer to the presence of gallstones or to any disease caused by gallstones, and choledocholithiasis refers to the presence of migrated gallstones within bile ducts.
Tomica Milosavljević is a Serbian doctor and politician. He served as Minister of Health in the Government of Serbia under four Prime Ministers with the total span of seven years. He is also employed as a full professor at the University of Belgrade and works in the Clinical Centre of Serbia in Belgrade.
A Klatskin tumor is a cholangiocarcinoma occurring at the confluence of the right and left hepatic bile ducts. The disease was named after Gerald Klatskin, who in 1965 described 15 cases and found some characteristics for this type of cholangiocarcinoma
The common bile duct, sometimes abbreviated as CBD, is a duct in the gastrointestinal tract of organisms that have a gallbladder. It is formed by the confluence of the common hepatic duct and cystic duct and terminates by uniting with pancreatic duct, forming the ampulla of Vater. The flow of bile from the ampulla of Vater into the duodenum is under the control of the sphincter of Oddi.
The common hepatic duct is the first part of the biliary tract. It joins the cystic duct coming from the gallbladder to form the common bile duct.
Cholestasis is a condition where bile cannot flow from the liver to the duodenum. The two basic distinctions are an obstructive type of cholestasis where there is a mechanical blockage in the duct system that can occur from a gallstone or malignancy, and metabolic types of cholestasis which are disturbances in bile formation that can occur because of genetic defects or acquired as a side effect of many medications. Classification is further divided into acute or chronic and extrahepatic or intrahepatic.
Cholangiocytes are the epithelial cells of the bile duct. They are cuboidal epithelium in the small interlobular bile ducts, but become columnar and carbonate-secreting in larger bile ducts approaching the porta hepatis and the extrahepatic ducts. They contribute to hepatocyte survival by transporting bile acids.
Michael W. Mulholland, MD, Ph.D. is a Professor of Surgery and the Chairman of the Department of Surgery at the University of Michigan.
The major duodenal papilla is a rounded projection in the duodenum into which the common bile duct and pancreatic duct drain. The major duodenal papilla is, in most people, the primary mechanism for the secretion of bile and other enzymes that facilitate digestion.
The biliary tract refers to the liver, gallbladder and bile ducts, and how they work together to make, store and secrete bile. Bile consists of water, electrolytes, bile acids, cholesterol, phospholipids and conjugated bilirubin. Some components are synthesized by hepatocytes ; the rest are extracted from the blood by the liver.
Gallbladder diseases are diseases involving the gallbladder and is closely linked to biliary disease, with the most common cause being gallstones (cholelithiasis).
Clidinium bromide (INN) is an anticholinergic drug. It may help symptoms of cramping and abdominal/stomach pain by decreasing stomach acid, and slowing the intestines. It is commonly prescribed in combination with chlordiazepoxide using the brand name Normaxin.
ATP-binding cassette sub-family G member 5 is a protein that in humans is encoded by the ABCG5 gene.
ATP-binding cassette sub-family G member 8 is a protein that in humans is encoded by the ABCG8 gene.
In general surgery, a Roux-en-Y anastomosis, or Roux-en-Y, is an end-to-side surgical anastomosis of bowel used to reconstruct the gastrointestinal tract. Typically, it is between stomach and small bowel that is distal from the cut end.
Trepibutone is a drug used for functional gastrointestinal disorders. Trepibutone promotes secretion of the bile and pancreatic juice, and accelerates flaccidity of the smooth muscle in the gastrointestinal tract to lower internal pressure of the gallbladder and bile duct. It improves the symptoms of the bile duct and pancreatic disease. It is usually used for improvement of cramp and bile secretion associated with cholelithiasis, cholecystitis, cholangitis, dyskinesia of the biliary tract or postcholecystectomy syndrome, or pain and gastrointestinal symptoms associated with chronic pancreatitis.
S-Nitrosoglutathione (GSNO) is an endogenous S-nitrosothiol (SNO) that plays a critical role in nitric oxide (NO) signaling and is a source of bioavailable NO. NO coexists in cells with SNOs that serve as endogenous NO carriers and donors. SNOs spontaneously release NO at different rates and can be powerful terminators of free radical chain propagation reactions, by reacting directly with ROO• radicals, yielding nitro derivatives as end products. NO is generated intracellularly by the nitric oxide synthase (NOS) family of enzymes: nNOS, eNOS and iNOS while the in vivo source of many of the SNOs is unknown. In oxygenated buffers, however, formation of SNOs is due to oxidation of NO to dinitrogen trioxide (N2O3). Some evidence suggests that both exogenous NO and endogenously derived NO from nitric oxide synthases can react with glutathione to form GSNO.
3,3,5-Trimethylcyclohexanol is a precursor to the vasodilator cyclandelate, the sunscreen component homosalate and the VP nerve agent. It can be synthesized by hydrogenation of isophorone. It has a mint flavour.
