From patient to pathologist, preparing tissue specimens for histological examination requires care, skill and sound The purpose of this “Technical Article” is to highlight the potential importance of tissue embedding methods for neuropathologic studies. Common preparation methods used Embedding StepsTurn the heat block on to melt the paraffin one hour before adding the tissue cassettesPlace the entire cassettes in up to°C paraffin bath forminutes Tissue ProcessingOverview. Results: The histological examination revealed the chicken skin and Histopathology evaluation basically compares diseased or experimentally altered tissues with matching sample from healthy or control counterparts. Since the tissue blocks are very thin in thickness they need a supporting medium in which the tissue blocks are embedded The paraffin-embedded blocks were cut intoμm sections and stained using hematoxylin and eosin (H&E) for histological study. The various commonly used embedding media are discussed in this section along with the process of the embedding. Therefore, it is very important to rigorously standardize every histology process (i.e., specimen sampling, trimming, embedding, sectioning, and staining) The choice of the embedding medium of the tissue depends on type of tissue, type of microtomy and also type of microscope to examine the tissue. Liquid paraffin is the most commonly used embedding medium in the histopathology laboratory Pathology Leaders. “Tissue processing” describes the steps required to take animal or human tissue from fixation to the state of complete infiltration with a From patient to pathologist, preparing tissue specimens for histological examination requires care, skill and sound procedures.
