Take the diseased tissue of a certain size, with histological methods are usually made of pathological [diseased tissue embedded in paraffin blocks, the use slicer sliced, then hematoxylin - eosin (HE) staining], with microscopic lesions further examination. Lesions occur in the development process, and finally make a pathological diagnosis. The production will be part of a lesion tissue or organs through a variety of chemicals and handle burial law, making it fixed sclerosis, thinly sliced ??on a slicer biopsy, adhered to the glass slide, stained with various colors, for use in examined under a microscope to observe pathological changes, make the pathological diagnosis, provide help for clinical diagnosis and treatment. (4) specification drawn parts: To accurately drawn by anatomical pathology reports, pathological specimens drawn in accordance with each lesion, the different nature of pathology practices, drawn in accordance with the requirements of standardization. (5) selected slice tissue blocks: organizational structure based on the various organs to determine its facets. Longitudinal or transverse often display key pathological tissue morphology of what it meant, as long tubular organ to cross as well. (6) to keep the material clean: if blood, dirt, mucus, food, feces, etc., can be rinsed with water and then placed on the tissue block clean fixative. (7) maintain the original form of organization: the fresh tissue after fixation, more or less shrinkage phenomenon, sometimes even completely deformed. To do this you can flatten the organization to maintain the original shape as possible. Pathological biopsy _ _ making voyage teaching provided by Xinxiang City Teaching Equipment Co. voyage.
