| antithrombin III | <haematology> Antithrombin III is a protein which stimulates the removal of blood clots in the bloodstream. Small blood clots form normally within the bloodstream, but are normally dissolved via the bodys antithrombin III. Conditions that may have an associated low value of antithrombin III include: liver disease and DIC. Normal values are: 0.20 to 0.45 mg/ml or more than 50% of the laboratory control value. Conditions where there is a deficiency of this important protease inhibitor can result in a condition of hypercoagulation, resulting in an increased risk for blood clot formation. Inheritance: autosomal dominant. (13 Jan 1998) |

| congenital antithrombin III deficiency | Antithrombin III is a protein which stimulates the removal of blood clots in the bloodstream. Small blood clots form normally within the bloodstream, but are normally dissolved via the bodys antithrombin III. The deficiency of antithrombin III will result in an increased risk for blood clot formation causing organ damage. This is an inherited as a autosomal dominant trait. Inheritance: autosomal dominant.

| antithrombin | Any substance that inhibits or prevents the effects of thrombin in such a manner that blood does not coagulate. A deficiency of antithrombin results in impaired inhibition of coagulation factors IIa, IXa, and Xa in plasma, causing recurrent thrombosis. Antithrombin III, an antithrombin at present somewhat conjectural and biochemically not well characterised. Deficiency is commonly inherited as an autosomal dominant trait; one of the few known mendelizing disorders to which thrombotic disease occurs. Normal antithrombin, an antithrombin naturally occurring in blood and certain tissues under normal conditions in contrast to abnormal states or antithrombin from other sources. (05 Mar 2000) |
| antithrombin test | A procedure for estimating the inhibitory effect of a defibrinated specimen of plasma on the action of thrombin in converting fibrinogen to fibrin. (05 Mar 2000) |
| angiotensin III | <chemical> A heptapeptide formed by the enzymatic hydrolysis of angiotensin II. It has greater activity than angiotensin II for stimulating aldosterone synthesis and in the release of prostaglandins but only 20% of the pressor activity. Chemical name: Angiotensin II, 1-de-L-aspartic acid- (12 Dec 1998) |
| annexin III | <enzyme> A protein of the annexin family that catalyses the conversion of 1-d-inositol 1,2-cyclic phosphate and water to 1-d-myo-inositol 1-phosphate. Chemical name: 1-D-myo-Inositol-1,2-cyclic-phosphate 2-inositolphosphohydrolase Registry number: EC 3.1.4.36 (12 Dec 1998) |
| apolipoprotein C-III | <biochemistry> An apolipoprotein found in VLDL, HDL, and chylomicrons. (05 Mar 2000) |
| arsenazo III | <chemical> Metallochrome indicator that changes colour when complexed to the calcium ion under physiological conditions. It is used to measure local calcium ion concentrations in vivo. Pharmacological action: dyes, indicators and reagents. Chemical name: 2,7-Naphthalenedisulfonic acid, 3,6-bis((2-arsonophenyl)azo)-4,5-dihydroxy- (12 Dec 1998) |
| arteriae intercostales posteriores III-XI | posterior intercostal arteries 3-11 |
| band III protein | <protein> A 90 kD protein embedded in the surface of the human erythrocyte membrane, identified as the major anion transport/exchange protein. When the red blood cell is in the lungs, brings chlorine ion into the cell in exchange for bicarbonate. Analogous proteins exist in other erythrocytes. A dimeric transmembrane glycoprotein, with binding sites for many cytolasmic proteins, including ankyrin, on its cytoplasmic domain. (18 Nov 1997) |
| palpebra III | The semilunar fold formed by the palpebral conjunctiva at the medial angle of the eye, a fold of the conjunctival mucous membrane found in many animals; normally partially hidden in the medial canthus of the eye when at rest, it may be extended to cover part or all of the cornea in a winking-like action to clean the cornea, as in birds. Synonym: membrana nictitans, nictitating membrane, palpebra III, palpebra tertia, third eyelid. Synonym: plica lunata, plica semilunaris of eye, semilunar conjunctival fold. (05 Mar 2000) |
| ramus collateralis arteriarum intercostalium posteriorum III-XI | Branch arising near angle of rib and descending to run along superior border of rib below; distribution: lower half of intercostal spaces 3-11; anastomoses: collateral branches of anterior intercostal arteries. Synonym: ramus collateralis arteriarum intercostalium posteriorum III-XI. (05 Mar 2000) |
| ramus cutaneus medialis rami dorsalis arteriarum intercostalium posteriorum III-XI | Medial cutaneous branch of dorsal branch of posterior intercostal arteries. See: medial cutaneous branch. (05 Mar 2000) |
| ramus dorsalis arteriarum intercostalium posteriorum III-XI | Terminal branch (with ventral branch) of the 3rd through 11th posterior intercostal arteries, distributed to thoracic portion of posterior vertebral column, spinal cord and environs, and back. Synonym: ramus dorsalis arteriarum intercostalium posteriorum III-XI. (05 Mar 2000) |
| malocclusion, angle class III | Malocclusion in which the mandible is anterior to the maxilla as reflected by the first relationship of the first permanent molar (mesioclusion). (12 Dec 1998) |
