| haematoxylin bodies | Poorly defined, homogeneous basophilic remnants of whole nuclei, an occasional finding in the fixed tissues of patients with systemic lupus erythematosus, but observed more frequently in the renal glomeruli and the walls of blood vessels, and probably related to the LE phenomenon; so named because of their affinity for haematoxylin stain.

| haematoxylin-malachite green-basic fuchsin stain | <technique> A stain for epoxy resin-extracted sections; semi-thick sections have their plastic dissolved out and the residual tissue is stained sequentially with the various dyes; nuclei and astrocytes are purplish-pink and myelin, lipid droplets, nucleoli, and oligodendrocytes are bright blue-green. (05 Mar 2000) |
| haematoxylin-phloxine B stain | <technique> A stain for intact epoxy sections; semi-thick sections of plastic-embedded tissues have the following structures stained blue to black; chromatin, nucleoli, basophilic cytoplasm, mitochondria, plasma and nuclear membranes, anisotropic myofibrils, mast cell granules, and elastic membranes of blood vessels; appearing pink to red are collagen fibrils, reticulum, goblet cell mucins, hyalin cartilage matrix, stereocilia, cytoplasm, and erythrocytes; fat droplets and perichondrocyte matrix are green.
