(4) specification drawn parts: To accurately drawn by anatomical and pathological specimens were drawn according to each lesion, the different nature, 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 tissue morphology is often the key display, such as a long tubular organ to cross as well. (6) to keep the material clean: if blood, dirt, mucus, food, feces and other Hebei biopsy 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. Grilled slices and toasted slices dewaxing, usually 60 ℃ temperature inside the roast slices about 0.5 to 1 hour, the temperature is too high Puyang biopsy can cause cell contraction sliced; time is too short (less than 20 minutes), is likely to cause off tablets. Dewaxing is also important Xuchang biopsy, if dewaxing not clean, easy to slice uneven coloring or shading biopsy, therefore, dewaxing with xylene should be changed frequently, usually with three xylene per 500ml of liquid handling 500 After replacing the appropriate time slices. When the temperature is below 18 ℃, must be sliced ??out from the oven immediately placed dewaxing in xylene or xylene into the temperature inside to warm up (about 37 ℃) dewaxing not exceed 60 ℃ . Then purified by high concentrations of alcohol to the low concentration of alcohol wash xylene, to water. Hebei biopsy pathology _ _ teaching voyage by voyage Teaching Equipment Co., Ltd.
