| gel diffusion precipitin tests in one dimension | Precipitin test's in which antigen solution and antibody incorporated in agar are layered in tubes, permitting effective diffusion in the vertical dimension; the antibody-containing agar may be overlaid directly with antigen solution (single (gel) diffusion in one dimension).

| NAD 3 alpha-hydroxy-5 alpha-pregnan-20-one-oxidoreductase | <enzyme> From rat liver microsomes Registry number: EC 1.1.1.- Synonym: nad-3-hp-20-oor (26 Jun 1999) |
| one-carbon fragment | The formyl group or the methyl group that takes part in transformylation or transmethylation reactions; by means of these reactions, a group containing a single carbon atom is added to a compound being biosynthesised, adding a methyl group (as in thymidine formation), adding a hydroxymethyl group (as in serine biosynthesis), or closing a ring (as in purine formation). (05 Mar 2000) |
| one-carbon group transferases | <enzyme> A subclass of transferases that transfer chemical groups containing a single carbon. These include the methyltransferases, the hydroxymethyl and formyl transferases, the carboxyl and carbamoyl transferases, and the amidinotransferases. Registry number: EC 2.1 (12 Dec 1998) |
| one-hand | Employing one hand; as, the one-hand alphabet. See: dactylology. (04 Mar 1998) |
| one-horned uterus | An obsolete term for unicorn uterus. (05 Mar 2000) |
| one-sided | 1. Having one side only, or one side prominent; hence, limited to one side; partial; unjust; unfair; as, a one-sided view or statement. "Unguarded and one-sided language." 2. <botany> Growing on one side of a stem; as, one-sided flowers. One-sid"ed-ly, One-sidedness. Source: Websters Dictionary (01 Mar 1998) |
| 3a-hydroxy-5a-pregnan-20-one | A catabolite of progesterone; found in the urine of pregnant women. (05 Mar 2000) |
| 7 alpha-hydroxy-4-cholesten-3-one-12 alpha monooxygenase | <enzyme> Liver microsomal enzyme active in conversion of cholesterol to cholic acid; introduces a 12 alpha-hydroxyl group into the steroid nucleus of cholesterol Registry number: EC 1.14.99.- Synonym: 7-hco-monooxygenase, hco 12 alpha-hydroxylase (26 Jun 1999) |
| -one | <chemistry, suffix> A termination indicating that the hydrocarbon to the name of which it is affixed belongs to the fourth series of hydrocarbons, or the third series of unsaturated hydrocarbonsl as, nonone. (29 Oct 1998) |
| ACE level | <investigation> This is a blood test which measures the concentration of angiotensin-converting enzyme (ACE) in the bloodstream. Elevations in angiotensin-converting enzyme are seen sarcoidosis, histoplasmosis, alcoholic cirrhosis, asbestosis, berylliosis, diabetes, Hodgkin's disease, hyperthyroidism, amyloidosis, primary biliary cirrhosis, idiopathic pulmonary fibrosis, pulmonary embolism, scleroderma, silicosis, tuberculosis, Gaucher's disease and leprosy. The normal values are 18 to 67 U/ml over 20 years of age (people under 20 have higher levels). (15 Jan 1998) |
| acoustic reference level | The biological reference level for sound measurements. When the term decibel is used to indicate the noise level, a reference quantity is implied; this reference value is usually expressed as a sound pressure of 20 micronewtons per square meter. The reference level is referred to as 0 decibels, the baseline of the scale of noise level's; this baseline is considered the weakest sound that can be heard by a person with very good hearing in an extremely quiet location. Other equivalent reference level's still being used include 0.0002 microbar and 0.0002 dyne per square centimeter. (05 Mar 2000) |
| background level | The average amount of a substance present in the environment. Originally referring to naturally occurring phenomena. Used in toxic substance monitoring. (05 Dec 1998) |
| blood porphyrin level | A test which is used to measure red blood cell porphyrin levels. Porphyrins are pigments found in both animal and plant life. This test is useful in evaluating any number of porphyrin disorders (involving the various porphyrins) of red blood cells. Increased levels of coproporphyrins can indicate congenital erythropoietic porphyria or sideroblastic anaemia. Increased protoporphyrins may be seen in infection, thalassaemia, sideroblastic anaemia, iron deficient anaemia, increased erythropoiesis and lead poisoning. Increased uroporphyrins may indicate congenital erythropoietic porphyria or erythropoietic protoporphyria. (27 Sep 1997) |
| carbon dioxide blood level | A measure of the bicarbonate level in the blood based on a venipuncture specimen. The serum carbon dioxide is one of the normally reported values in the electrolytes profile. Lower levels of carbon dioxide indicate an acidosis. The normal level is 20 to 29 mEq/L. Lower than normal levels can indicate diabetic ketoacidosis, lactic acidosis, alcoholic ketoacidosis, kidney disease, renal failure, diarrhoea, Addison's disease, ethylene glycol poisoning or methanol poisoning. Greater than normal levels can be seen with excessive vomiting, hyperaldosteronism and Cushing's syndrome. (27 Sep 1997) |
