Pathology Technical Service Experiment Principles

u0026 NBSP When studying the tissue or cells of the biological object, except for certain organisms available to phase difference microscopy or polarizing microscope, the remaining major organisms, because the tissue is thick, and the light is not easily observed by the internal and other relationships. In order to achieve this, the tissue of the organism is cut into thin slices, and the light is easily transmitted through a series of treated, and it can be observed. When making a slice or ultra-thin slice, it is difficult to make a thick and uniform slice due to the softness of the tissue, or the local soft and hard unevenness. Therefore, useful substances soaked inside the tissue, hardened throughout the tissue to facilitate cutting into sheets. Squiking method for sections as a support for paraffin. Paraffin section is generally historical, pathology, etc., so much, it has many advantages: saving time, easy operation, can cut into thin slice (4um or less), can make continuous slices, The organizational block can be embedded in paraffin * Save.

Technical application paraffin slice is a wide range of methods for organism conventional studios. Paraffin slices are not only used to observe the morphological structure of normal cell tissue, but also the main methods for studying, observing and determining the morphological changes of cellular tissue.
