The syntheses of brazilin and haematoxylin
Tetrahedron, 1970Abstract The synthesis of dl-brazilin and dl-haematoxylin have been achieved starting with O-trimethyl-deoxybrazilone (or its analogue in the haematoxylin series). The chief obstacle was overcome by taking advantage of the formation of brazilein from a phenolic pinacol obtained in stages from O-trimethyl-brazilane, which has already been synthesized.

The ultrastructure of glomerular haematoxylin bodies
The Journal of Pathology, 1981AbstractThe ultrastructural features of haematoxylin bodies, present in a patient with active lupus glomerulonephritis, appear to include cellular elements, especially dense chromatin of probable neutrophil leucocyte origin and electro‐dense, immune complex‐like material.

Haematoxylin – the story of the blues
British Journal of Biomedical Science, 2018The farther back you can look, the farther forward you are likely to see [1].― Winston ChurchillHaematoxylin is arguably the most well known of all dyes used in pathology.

Golgi-like staining with haematoxylin
Neuroscience Letters, 1980Abstract Under certain conditions the Loyez method [4], an iron-haematoxylin stain for myelin, will impregnate the perikarya, dendrites and axons of neurones. This occurs (in chick embryos and young mice) at certain stages of normal development, and may be provoked in adult animals by a lesion of the brain; but it does not occur in normal, unoperated

Cytology & Histology International Journal, 2023
Natural dyes are employed for staining various histological tissues, which serve as a significant alternative source for synthetic dye, thereby reducing the burden of buying synthetic dyes and its impact on the environment. This study aimed to extract the black plum plant (syzigium cumin) using an aqueous solvent and investigate its staining properties

Staining of gastrin cells with lead-Haematoxylin
The Histochemical Journal, 1975Fixation of fragments of human antral mucosa with Helly's fluid allows gastrin-containing cells to be identified by an immunofluorescence technique. Lead-Haematoxylin staining carried out on the same sections shows selective reactivity of the immunofluorescent cells.

On the mechanism of Mallory's phosphotungstic acid‐haematoxylin stain
Journal of Microscopy, 1980SUMMARYThe mechanism of Mallory's (1900) phosphotungstic acid‐haematoxylin (PTAH) stain is not yet fully understood; staining properties vary with the age of the dye solution. In this study, a 1‐year‐old solution was employed as described previously.

The oxidation products of Haematoxylin and their role in biological staining
The Histochemical Journal, 1972Haematoxylin and its oxidation products were studied by t.l.c., and i.r., n.m.r., u.v. and visible spectroscopy. Oxidation (‘ripening’) of Haematoxylin with oxygen, from the atmosphere or a cylinder, gave Haematein as the only major product; whereas with non-gaseous oxidants such as hydrogen peroxide, potassium permanganate and sodium iodate, further ...
