Synonym: achromacyte, achromatocyte, ghost corpuscle, phantom corpuscle, Ponfick's shadow, shadow corpuscle, shadow, Traube's corpuscle. Origin: G.

| exudation corpuscle | A cell present in an exudate that assists in the organization of new tissue. Synonym: exudation cell, inflammatory corpuscle, plastic corpuscle. (05 Mar 2000) |
| Zimmermann's corpuscle | <haematology> A discoid cell (3m diameter) found in large numbers in blood, important for blood coagulation and for haemostasis by repairing breaches (small breaks) in the walls of blood vessels. Platelet _ granules contain lysosomal enzymes, dense granules contain ADP (a potent platelet aggregating factor) and serotonin (a vasoactive amine). They also release platelet-derived growth factor which presumably contributes to later repair processes by stimulating fibroblast proliferation. Synonym: thrombocytes. (09 Oct 1997) |
| lymph corpuscle | Lymphatic corpusclelymphoid corpuscle, a mononuclear type of leukocyte formed in lymph nodes and other lymphoid tissue, and also in the blood. (05 Mar 2000) |

| acid red 91 | The disodium salt of 4',5'-dibromo-2',7'-dinitrofluorescein. Synonym: acid red 91, eosin I bluish. (05 Mar 2000) |
| algae, red | Algae of the division rhodophyta, in which the pigment is predominantly red; common genera are gelidium, gracilaria, and polysiphonia. (12 Dec 1998) |
| alizarin red S | Sodium alizarin sulfonate;used as a stain for calcium in bone (calcium appears red-orange, magnesium, aluminum, and barium are varying shades of red), in the determination of fluorine; as a pH indicator it changes from yellow to purple between pH 3.7 and 5.2. (05 Mar 2000) |
