Abstract
Staining of the the tissues is an art which gives fruitful results over a period of time. Many researchers have used various stains, some are costly and
some are economical. Special stains like Mallory's trichrome and Massson's trichrome are routinely used for staining various tissues. As few
ingredients of Masson's Trichrome were not available, we replaced certain ingredients which were not available by readily available ingredients on
an experimental basis and a study was carried out. We used Ponceau S instead of Ponceau 2R and Ehrlich's Haematoxylin instead of Weigert's Iron
Haematoxylin for staining parafn sections of tongue, pituitary gland, colon, adrenal gland and hyaline cartilage. Tissues were collected from the
cadavers allotted for rst year MBBS students for dissection at Dr B R Ambedkar medical college, Bangalore. After processing the tissues, parafn
embedded blocks were prepared and the sections were taken and later washed in tap water followed by staining with special stains with certain
ingredients replaced due to non availability. After that, sections were washed by water, dehydrated in graded alcohol, cleared in xylene and
mounted in DPX and the Photographs of the slides were taken through the microscope by focusing both under low power and high power. In routine
Masson's Trichrome stain, Ponceau S was used instead of Ponceau 2R because of it's non-availability. Further the cost of Ponceau S is very much
lesser than Ponceau 2R. Also Ehrlich's Haematoxylin was used instead of Weigert's Iron Haematoxylin. We obsereved that various components like
nuclei, cytoplasm, muscle, acidophil and basophil granules, collagen, cartilage, mucin were all well differentiated. On an experimental basis, we
replaced the components Ponceau 2R by Ponceau S and Weigert's Iron Haematoxylin by Erhlich's Haematoxylin in Masson's Trichrome method
of staining and various tissues were stained with good results.
