| type I H/S mucopolysaccharidosis | <syndrome> Although clinically distinct diseases, fibroblasts from patients with Hurler syndrome and with Scheie syndrome do not cross complement in culture, suggesting that the enzyme defect is the same. (18 Nov 1997) |
|---|---|
| type I hyperlipoproteinaemia | <biochemistry> An rare inherited disorder where there is a deficiency of an enzyme (lipoprotein lipase) which breaks down fat molecules, causing the accumulation of fats or lipoproteins in the blood. Symptoms in infancy include abdominal pain (appears as if its colic), failure to thrive and skin lesions (xanthomas). Origin: Gr. Haima = blood (27 Sep 1997) |
| type II acrocephalosyndactyly | type II acrocephalosyndactyly |
| type II cells | Cuboidal cell's connected with the squamous pulmonary alveolar cell's and having in their cytoplasm lamellated bodies (cytosomes) that represent the source of the surfactant that coats the alveoli. Synonym: granular pneumonocytes, type II cells. (05 Mar 2000) |
| type II collagen | Collagen unique to cartilage, nucleus pulposis, notochord, and vitreous body; it forms as thin highly glycosylated fibrils. (05 Mar 2000) |
| type II diabetes | <disease> An often mild form of diabetes mellitus of gradual onset, usually in obese individuals over age 35; absolute plasma insulin levels are normal to high, but relatively low in relation to plasma glucose levels; ketoacidosis is rare, but hyperosmolar coma can occur; responds well to dietary regulation and/or oral hypoglycaemic agents, but diabetic complications and degenerative changes can develop. (05 Mar 2000) |
| type II dip | Late deceleration of the foetal heart rate, 30 seconds or more after the height of uterine contraction, as displayed on a foetal monitor graph. (05 Mar 2000) |
| type II error | The statistical error (said to be of the second kind or beta error) made in testing an hypothesis when it is concluded that a treatment or intervention is not effective when it really is. Sometimes referred to as a false negative. (12 Dec 1998) |
| type II familial hyperlipoproteinaemia | Hyperlipoproteinaemia characterised by increased plasma levels of beta-lipoproteins, cholesterol, and phospholipids, but normal triglycerides; heterozygotes have mild lipid changes and are susceptible to atherosclerosis in middle age, but homozygotes have severe changes often with generalised xanthomatosis and xanthelasma, and frank clinical atherosclerosis as young adults. The primary defect is a deficiency of apoprotein of VLDL, and the disorder is divided into two classes: 1) type IIA, which has elevated LDL due to a deficiency of the receptor or a modified apolipoprotein B-100; 2) type IIB, which has elevated LDL and triglycerides; autosomal dominant inheritance. Synonym: familial hyperbetalipoproteinaemia, familial hypercholesteraemic xanthomatosis, familial hypercholesterolaemia. (05 Mar 2000) |
| type II hyperlipoproteinaemia | <biochemistry> A relatively rare (7 out of 1,000) genetic disease in which there is elevation in the blood triglycerides, cholesterol and low density lipoprotein (LDL). Also called type II hyperlipoproteinaemia, familial hyperlipoproteinaemia or familial hypercholesterolaemia. Origin: Gr. Haima = blood (27 Sep 1997) |
| type III acrocephalosyndactyly | An autosomal dominant syndrome with variable expression of brachycephaly, maxillary hypoplasia, prominent ear crus, syndactyly, facial asymmetry, shallow orbits, telecanthus, and nasal septal deviation; may show mental retardation. Synonym: Saethre-Chotzen syndrome. (05 Mar 2000) |
| type III collagen | Collagen characteristic of reticular fibres. (05 Mar 2000) |
| type III familial hyperlipoproteinaemia | Hyperlipoproteinaemia characterised by increased plasma levels of LDL, beta-lipoproteins, pre-beta-lipoproteins, cholesterol, phospholipids, and triglycerides; hypertriglyceridemia induced by a high carbohydrate diet, and glucose tolerance is abnormal; frequent eruptive xanthomas and atheromatosis, particularly coronary artery disease; biochemical defect lies in apolipoproteins; there are many varieties. Synonym: carbohydrate-induced hyperlipaemia, dysbetalipoproteinaemia, familial hyperbetalipoproteinaemia and hyperprebetalipoproteinaemia, familial hypercholesterolaemia with hyperlipaemia. (05 Mar 2000) |
| type III hyperlipoproteinaemia | <biochemistry> An inherited disorder (gene defect) where both cholesterol and triglycerides are elevated in the same patient. This condition accelerates the effects of atherosclerosis and thus increases the risk of cardiovascular disease. Conditions such as hypothyroidism, obesity and diabetes enhances this risk. Origin: Gr. Haima = blood (27 Sep 1997) |
| type III hypersensitivity reaction | An immunologic category of diseases evoked by the deposition of antigen-antibody or antigen-antibody-complement complexes on cell surfaces, with subsequent involvement of breakdown products of complement, platelets, and polymorphonuclear leukocytes, and development of vasculitis; nephritis is common. Arthus phenomenon and serum sickness are classic examples, but many other disorders, including most of the connective tissue disease's, may belong in this immunologic category; immune complex disease's can also occur during a variety of disease's of known aetiology, such as subacute bacterial endocarditis. See: autoimmune disease. Synonym: immune complex disorder, type III hypersensitivity reaction. (05 Mar 2000) |
