| 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%.

| 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) |
| accessory parotid gland | An occasional islet of parotid tissue separate from the mass of the gland, lying anteriorly just above the commencement of the parotid duct. Synonym: glandula parotidea accessoria, admaxillary gland, glandula parotis accessoria, socia parotidis. (05 Mar 2000) |
| parotid | <anatomy> Situated near the ear; applied especially to the salivary gland near the ear. Of, pertaining to, or in the region of, the parotid gland. <anatomy> Parotid gland, one of the salivary glands situated just in front of or below the ear. It is the largest of the salivary glands in man, and its duct opens into the interior of the mouth opposite the second molar of the upper jaw. Origin: L. Parotis, -idis, Gr,; beside, near +, the ear: cf. F. Parotide. <anatomy> The parotid gland. Source: Websters Dictionary (01 Mar 1998) |
| parotid abscess | Rapidly progressive suppuration in the parotid gland; a complication of parotitis. (05 Mar 2000) |
| parotid bed | The structures which surround and contact the parotid, forming the boundaries of the parotid space: anteriorly, the ramus of the mandible flanked by the masseter and medial pterygoid muscles; medially, the pharyngeal wall, carotid sheath and structures originating from the styloid process; posteriorly, the mastoid process, sternocleidomastoid muscle, and posterior belly of the digastric muscle; superiorly, the temporomandibular joint and the tympanic bone and cartilaginous portion of the external acoustic meatus.

| parotid branches | Branches to parotid gland; Nomina Anatomica lists parotid branches of 1) auriculotemporal nerve (rami parotidei nervi auriculotemporalis; 2) facial vein, rami parotidei venae facialis; 3) superficial temporal artery, ramus arteriae temporalis superficialis. Synonym: rami parotidei. (05 Mar 2000) |
| parotid duct | The duct of the parotid gland opening from the cheek into the vestibule of the mouth opposite the neck of the superior second molar tooth. Synonym: ductus parotideus, Blasius' duct, Stensen's duct, Steno's duct. (05 Mar 2000) |
