he·ma·tox·y·lin

(hē'mă-toks'i-lin)
[CI 75290] A crystalline compound containing the coloring matter of Haematoxylon campechianum (logwood), from which it is obtained by extraction with ether. It is used as a dye in histology, especially for cell nuclei and chromosomes, muscle cross-striations, and enterochromaffin cells, and as an indicator (red to yellow at pH 0.0-1.0, yellow to violet at pH 5.0-6.0).
Synonym(s): haematoxylin.

According to GOODWIN (1989), the haematoxylin and eosin-staining of tissue sections is a sensitive method for the identification of the parasites.
The counterstaining was performed with Harry's haematoxylin.
Paraffinated blocks were further processed in order to prepare 5 micron sections using microtome which then were stained by haematoxylin (Harris modified haematoxylin with acetic acid; Fisher Scientific, Pittsburgh, PA, USA) and eosin (10% in ethanol, Electron Microscopy Science, Pittsburgh, PA, USA) staining method and observed by light microscope.
The haematoxylin and eosin stained paraffin sections of the mass on low power showed tumor cells to infiltrate in solid sheets (Figure 2a).
Also, we fixed tissue of the nodule in a 10% neutral-buffed formalin, processed routinely, embedded in paraffin wax, sectioned at 4-6 mm and stained with haematoxylin and eosin (H&E) and Masson's trichrome methods.
Neuronal injury in the cortex was measured by staining sections with haematoxylin and eosin using the standard method (8).
They were then transferred to haematoxylin solution for 10 min, washed under running tap water for 10 min, and finally transferred to eosin solution for 5 min before redehydration by passage through 90[degrees] alcohol (2 x 1 min), 100[degrees] alcohol (2 x 1 min) and xylol (2 x 5 min).
These fibres are difficult to detect with haematoxylin and eosin staining especially during frozen sections.
These tissues were fixed in natural buffered formalin and then processed by using paraffin embedding technique for preparation of sections and stained with haematoxylin and eosin (H and E) for observing microscopic changes caused by M.
Histopathological examinations: Histopathological analysis was performed on primary tumours on haematoxylin and eosin stained sections.
