| alpha-amylase | <enzyme> An enzyme that catalyses the endohydrolysis of 1,4-alpha-glycosidic linkages in starch, glycogen, and related polysaccharides and oligosaccharides containing 3 or more 1,4-alpha-linked d-glucose units. Pharmacological action: anti-inflammatory agents. Chemical name: 1,4-alpha-D-Glucan glucanohydrolase Registry number: EC 3.2.1.1 (12 Dec 1998) |
|---|---|
| amylase | <enzyme> An enzyme produced in the pancreas and salivary glands. Elevation of the blood amylase is common in conditions of pancreatitis. (27 Sep 1997) |
| amylase-creatinine clearance ratio | A test for the diagnosis of acute pancreatitis; it is determined by measuring amylase and creatinine in serum and urine in apparently healthy individuals the renal clearance of amylase is less than 5% that of creatinine; in acute pancreatitis the ratio is said to be greater than 0.05 or 5%. (05 Mar 2000) |
| beta-amylase | <enzyme> An enzyme that catalyses the hydrolysis of 1,4-alpha-glycosidic linkages in starch, glycogen, and related polysaccharides and oligosaccharides so as to remove successive beta-maltose units from the non-reducing ends of the chains. Chemical name: 1,4-alpha-D-Glucan maltohydrolase Registry number: EC 3.2.1.2 (12 Dec 1998) |
| gamma-amylase | A hydrolase removing terminal alpha-1,4-linked d-glucose residues from nonreducing ends of chains, with release of beta-d-glucose. Synonym: acid maltase, amyloglucosidase, gamma-amylase, glucoamylase. (05 Mar 2000) |
| maltotriose-forming amylase | <enzyme> Also carries out transglycosylation, forming p-nitrophenyl alpha-maltotetraoside from maltotetraose and p-nitrophenyl alpha-d-glucopyranoside Registry number: EC 3.2.1.- Synonym: g3-amylase (26 Jun 1999) |
| glycosylated alpha-amylase | <enzyme> Contains a single biantennary n-linked oligosaccharide that terminates with the structure fucalpha1,3(galbeta1,4)glcnac Registry number: EC 3.2.1.- Synonym: human glycosylated alpha-amylase (26 Jun 1999) |
| saccharogen amylase | <enzyme> An enzyme that catalyses the hydrolysis of 1,4-alpha-glycosidic linkages in starch, glycogen, and related polysaccharides and oligosaccharides so as to remove successive beta-maltose units from the non-reducing ends of the chains. Chemical name: 1,4-alpha-D-Glucan maltohydrolase Registry number: EC 3.2.1.2 (12 Dec 1998) |
| acidified serum test | Lysis of the patient's red cells in acidified fresh serum, specific for paroxysmal nocturnal haemoglobinuria. Synonym: Ham's test. (05 Mar 2000) |
| anticomplementary serum | Serum that destroys or inactivates complement. (05 Mar 2000) |
| antiepithelial serum | An antiserum (cytotoxin) for epithelial cells. (05 Mar 2000) |
| anti-kidney serum nephritis | Experimental glomerulonephritis produced by injection of antiserum to kidney. (05 Mar 2000) |
| antilymphocyte serum | Immunoglobulins raised xenogeneically against lymphocyte populations. Referring particularly to antisera recognising one or more antigenic determinants on T-cell populations. Of use in experimental immunosuppression. (18 Nov 1997) |
| antirabies serum | A sterile solution containing antibodies obtained from the blood serum or plasma of a healthy animal, or human, that has been immunised against rabies by means of vaccine; administered immediately after severe or multiple bites by domestic animals suspected to be rabid and in all wild animal bites, to be followed by a regimen of rabies vaccine. (05 Mar 2000) |
| antireticular cytotoxic serum | An antiserum specific for cells of the reticuloendothelial system. (05 Mar 2000) |
