| acidophil cell | A cell whose cytoplasm or its granules stain with acid dyes. (05 Mar 2000) |
|---|---|
| acidophil granule | A granule that stains with an acid dye such as eosin. Synonym: oxyphil granule. (05 Mar 2000) |
| acidophile | <microbiology> Describes any microorganism that can or must live in an acidic environment (pH below 6). (06 May 1997) |
| acidophilic | Having an affinity for acid dyes; denoting a cell or tissue element that stains with an acid dye, such as eosin. Synonym: acidophil, acidophile, oxychromatic. (05 Mar 2000) |
| acidophilic leukocyte | A polymorphonuclear leukocyte characterised by many large or prominent, refractile, cytoplasmic granules that are fairly uniform in size and bright yellow-red or orange when treated with Wright's or similar stains; the nuclei are usually larger than those of neutrophils, do not stain as deeply, and characteristically have two lobes (a third lobe is sometimes interposed on the connecting strand of chromatin); these leukocyte's are motile phagocytes with distinctive antiparasitic functions. Synonym: acidophilic leukocyte, eosinocyte, eosinophil, eosinophile, oxyphil, oxyphile, oxyphilic leukocyte. (05 Mar 2000) |
| acidophilus | <microbiology> Bacteria found in yogurt that help restore a supportive bacterial environment to an intestinal tract affected by disease and antibiotics. Ingesting acidophilus also may be useful in preventing candidiasis (thrush), including in the vagina. (13 Nov 1997) |
| acidophilus milk | Milk inoculated with a culture of Bacillus acidophilus. (05 Mar 2000) |
| acidosis | <biochemistry> A metabolic condition, characterised by an increase in hydrogen ion concentration, that occurs when the body is no longer able to buffer free hydrogen ions in the blood, resluting from either the accumulation of acid or depletion of the alkaline reserve (bicarbonate) in the blood and body tissues. This usually causes the pH of the blood to drop (and become more acidic). Compare: alkalosis. (10 May 1997) |
| acidotic | Pertaining to or indicating acidosis. (05 Mar 2000) |
| acids, carbocyclic | Carboxylic acids that have a homocyclic ring structure in which all the ring atoms are carbon. (12 Dec 1998) |
| acids, heterocyclic | A class of acids containing a ring structure in which atleast one atom other than carbon is incorporated. (12 Dec 1998) |
| acids, noncarboxylic | Inorganic acids with a non metal, other than carbon, attached to hydrogen, or an acid radical containing no carbon. (12 Dec 1998) |
| acidulant | <pharmacology> Food additive that is used to impart a sharp flavour. The most common acidulant is citric acid (produced by the fermentation of molasses or other sugars by the fungusAspergillus niger). Malic acid and fumaric acid are also frequently used. (06 May 1997) |
| acidulate | To make sour or acid in a moderate degree; to sour somewhat. Origin: Cf. F. Aciduler. See Acidulous. Source: Websters Dictionary (01 Mar 1998) |
| acidulated phosphate fluoride | <chemical> Phosphoric acid, mixt. With sodium fluoride (naf). A sodium fluoride solution, paste or powder, which has been acidulated to pH 3 to 4 and buffered with a phosphate. It is used in the prevention of dental caries. Pharmacological action: fluorides, topical. Chemical name: Phosphoric acid, mixt. With sodium fluoride (NaF) (12 Dec 1998) |
