| calculi | An abnormal concretion occurring within the animal body and usually composed of mineral salts. (12 Dec 1998) |
|---|---|
| matrix calculi | <radiology> Radiolucent, associated with Proteus infection, composition: 2/3 mucoprotein, 1/3 mucopolysaccharide see also: renal calculi (12 Dec 1998) |
| renal calculi | <radiology> Common: calcium phosphate (8%), calcium oxalate (most common: 73%, most opaque), magnesium ammonium phosphate (struvite), uncommon: diammonium calcium phosphate, magnesium phosphate, rare: cystine (faintly opaque; 1%), urate (lucent; 7%), xanthine see: matrix calculi (12 Dec 1998) |
| salivary gland calculi | Calculi occurring in a salivary gland. most salivary gland calculi occur in the submandibular gland, but can also occur in the parotid gland and in the sublingual and minor salivary glands. (12 Dec 1998) |
| kidney calculi | Calculi occurring in the kidney. Calculi too large to pass spontaneously range in size from 1 cm to the staghorn stones that occupy the renal pelvis and calyces. Bilateral renal calculi cause additional problems, with infection a common occurrence. (12 Dec 1998) |
| ureteral calculi | Calculi of the ureter. The calculus in the ureter is usually the result of the passage of one originating in the kidney. It occurs usually in mid-life, rarely in children; it occurs more frequently in males than females. (12 Dec 1998) |
| urinary calculi | Calculi in any part of the urinary tract. Vesical calculi (bladder calculi) are those found in the urinary bladder; renal calculi (kidney calculi) are those found in the pelvis of the kidney. Types of urinary calculi are often classified by chemical composition or pattern of chemical composition distribution. Urinary calculi types include alternating or combination, cystine, decubitus, encysted, fibrin, hemp seed, matrix, mulberry, oxalate, struvite, urostealith, and xanthic calculi. (12 Dec 1998) |
| aberrant bile ducts | Small duct's occasionally present in the ligaments of the liver or originating from the surface of the liver. (05 Mar 2000) |
| bile | <gastroenterology> A greenish-yellow fluid secreted by the liver and stored in the gallbladder. Bile plays an important role in the intestinal absorption of fats. Bile is secreted by the liver and contains cholesterol, bile salts and waste products such as bilirubin. Bile salts aid in the digestion of fats. Bile passes out of the liver via the bile duct where it is stored in the gallbladder and released in response to a fat-containing meal. (27 Sep 1997) |
| bile acid 3alpha-sulfate sulfohydrolase | <enzyme> Used for determination of serum 3alpha-sulfated bile acids; converts 3alpha-sulfated bile acids into 3beta-hydroxy bile acids Registry number: EC 3.1.6.- Synonym: 3alpha-sulfated bile acid sulfohydrolase, ba-3s sulfohydrolase (26 Jun 1999) |
| bile acid 7alpha-dehydratase | <enzyme> Enzyme in the bacterial bile acid 7alpha-dehydroxylation pathway Registry number: EC 4.2.1.- Synonym: c24 bile acid 7alpha-dehydratase, ba7alphad, baie gene product (26 Jun 1999) |
| bile acid 7 alpha-dehydroxylase | <enzyme> Mechanism is questionable: cholic acid - deoxycholic acid - chenodeoxycholic acid - lithocholic acid Registry number: EC 1.14.- Synonym: 7 alpha-dehydroxylase, bile acid 7-dehydroxylase, bile acid 7-alpha-dehydroxylase, bai a1, bai a2, bai a3, cholic acid 7alpha-dehydroxylase (26 Jun 1999) |
| bile acid-CoA ligase | <enzyme> Catalyses the synthesis of all bile acid-coas; in order to measure the activity of all bile acids, the bile acid is coupled with c(14)-glycine and measured with bile acid-CoA glycine-taurine n-acetyltransferase Registry number: EC 6.2.1.- (26 Jun 1999) |
| bile acids | Steroid acids found in bile; e.g., taurocholic and glycocholic acid's, used when biliary secretion is inadequate and for biliary colic. Their physiological roles include fat emulsification. Their synthesis is reduced in disorders of the peroxisomes. (05 Mar 2000) |
| bile acids and salts | <chemical> 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. Pharmacological action: cholagogues and choleretics, gastrointestinal agents. (12 Dec 1998) |
