| Altmann, Richard | <person> German histologist, 1852-1900. See: Altmann's fixative, Altmann's granule, Altmann's anilin-acid fuchsin stain, Altmann's theory, Altmann-Gersh method. (05 Mar 2000) |
| Altmann's anilin-acid fuchsin stain | <technique> A mixture of picric acid, anilin, and acid fuchsin which stains mitochondria crimson against a yellow background. (05 Mar 2000) |
| Altmann's fixative | A bichromate-osmic acid fixative. (05 Mar 2000) |
| Altmann's granule | A granule that has an affinity for fuchsin. Synonym: Altmann's granule. (05 Mar 2000) |
| Altmann's theory | A theory that protoplasm consists of granular particles (called bioblasts) that are clustered and enclosed in indifferent matter. (05 Mar 2000) |
| a granules | Large, rodlike, or filamentous granules found in several types of cells, especially platelets where they are the most numerous type of granule; contain secretory proteins, including fibrinogen, fibronectin, fibrospondin, von Willebrand factor (collectively known as adhesive proteins) and other proteins (platelet factor 4, platelet-derived growth factor, coagulation factor V, etc.). (05 Mar 2000) |
| argentaffin granules | Granule's that reduce silver ions from an ammoniacal silver nitrate staining solution. (05 Mar 2000) |
| Bensley's specific granules | Granule's in the cells of the islands of Langerhans in the pancreas. (05 Mar 2000) |
| Bollinger granules | Relatively small, but frequently microscopically visible, pale yellow or yellow-white granule's observed in the granulomatous lesion, or the exudate, in botryomycosis; the granule's consist of irregular aggregates or colonizations of Gram-positive cocci, usually staphylococci, term sometimes incorrectly used synonymously with Bollinger bodies. (05 Mar 2000) |
| volutin granules | A nucleoprotein complex found as cytoplasmic granules in certain bacteria, yeasts, and protozoa (such as trypanosome flagellates) which serves as food reserves. Synonym: volutin granules. (05 Mar 2000) |
| metachromatic granules | Granule's that stain a colour different from that of the dye used. See: metachromasia. Term sometimes used as a synonym for volutin. (05 Mar 2000) |
| chromaffin granules | Granules in the adrenal glands and various other organs, which are concerned with the synthesis, storage, metabolism, and secretion of epinephrine and norepinephrine. (12 Dec 1998) |
| chromophobe granules | Granule's that do not stain or stain poorly with the ordinary dyes; such granule's are present in some cells in the anterior lobe of the pituitary. (05 Mar 2000) |
| mucinogen granules | Granule's that produce mucin, as in cells of the salivary glands and in the gastric and intestinal mucosae. (05 Mar 2000) |
