| kidney tubular necrosis, acute | Acute kidney failure resulting from destruction of tubular epithelial cells. It is commonly attributed to exposure to toxic agents or renal ischemia following severe trauma. (12 Dec 1998) |

| leukaemia, erythroblastic, acute | A myeloproliferative disorder characterised by neoplastic proliferation of erythroblastic and myeloblastic elements with atypical erythroblasts and myeloblasts in the peripheral blood. (12 Dec 1998) |
| leukaemia, megakaryocytic, acute | Nonlymphocytic leukaemia in which 20-30% of the bone marrow or peripheral blood cells are of megakaryocyte lineage. Myelofibrosis or increased bone marrow reticulin is common. (12 Dec 1998) |
| leukaemia, myelocytic, acute | Progressive, malignant disease of the myeloid tissue in which the granular, polymorphonuclear leukocytes and their precursors predominate. (12 Dec 1998) |
| leukaemia, nonlymphocytic, acute | Acute leukaemia distinguished from acute lymphocytic leukaemia (all) by the morphology of the marrow and blood leukaemic cells. Cytoplasmic granules are usually present and the nucleus is usually large and irregular. Anll is more common in adults than all and occurs at any age. (12 Dec 1998) |
| leukoencephalitis, acute haemorrhagic | A rare, fatal postinfection or allergic demyelinating disease of the central nervous system having a fulminating course and occurring mainly in young adults. It is characterised by destruction of white matter to the point of liquefaction; widespread necrosis of blood vessel walls leading to the formation of multiple small haemorrhages in the involved areas and the exudation of fibrin into the surrounding tissue; and cellular infiltration of the necrotic areas. (12 Dec 1998) |
| liver failure, acute | A form of liver failure with rapid onset. It is often induced by the toxic effect of drugs and various toxic substances in experimental studies in animals and in clinical states in humans. If coma ensues, the constellation of neurological symptoms is referred to as hepatic encephalopathy. (12 Dec 1998) |
| acromial angle | The prominent angle at the junction of the posterior and lateral borders of the acromion. Synonym: angulus acromialis. (05 Mar 2000) |
| adjacent angle | An angle with a line in common with another angle. (05 Mar 2000) |
| alpha angle | The angle between the visual and optic axes as they cross at the nodal point of the eye, the angle between the visual line and the major axis of the corneal ellipse. (05 Mar 2000) |
| alveolar angle | The angle between the horizontal plane and a line connecting the base of the nasal spine and the middle point of the projection of the alveolus of the maxilla. (05 Mar 2000) |
| angle | 1. To fish with an angle (fishhook), or with hook and line. 2. <geometry> The figure made by two lines which meet. The difference of direction of two lines. In the lines meet, the point of meeting is the vertex of the angle. 3. A projecting or sharp corner; an angular fragment. "Though but an angle reached him of the stone." (Dryden) Curvilineal angle, one formed by two curved lines. External angles, angles formed by the sides of any right-lined figure, when the sides are produced or lengthened. Internal angles, those which are within any right-lined figure. Mixtilineal angle, one formed by a right line with a curved line. Oblique angle, one acute or obtuse, in opposition to a right angle. Obtuse angle, one greater than a right angle, or more than 90 deg . Rectilineal or Right-lined angle, one formed by two right lines. Right angle, one formed by a right line falling on another perpendicularly, or an angle of 90 deg (measured by a quarter circle). Solid angle, the figure formed by the meeting of three or more plane angles at one point. Spherical angle, one made by the meeting of two arcs of great circles, which mutually cut one another on the surface of a globe or sphere. Visual angle, the angle formed by two rays of light, or two straight lines drawn from the extreme points of an object to the center of the eye. 4. <astronomy> A name given to four of the twelve astrological houses. Origin: F. Angle, L. Angulus angle, corner; akin to uncus hook, Gr. Bent, crooked, angular, a bend or hollow, AS. Angel hook, fish-hook, G. Angel, and F. Anchor. (16 Mar 1998) |

| angle of anomaly | <ophthalmology> An obsolete term for the degree of deviation from parallelism of the visual axes of the eyes. (05 Mar 2000) |
| angle of antetorsion | <orthopaedics> The angle formed by a line drawn through the centre of the long axis of the neck of the femur meeting a line drawn in the transverse axis of the condyles, when the bone is viewed from above, looking straight down through the head of the femur. It is used to illustrate the normal degree of anteversion about 12 |
