Parafiinilevyyn

Parafiinilevyyn refers to a section of paraffin wax that has been processed for use in histology. Histology is the study of microscopic structures of tissues and organs. When a tissue sample is taken for examination, it often needs to be preserved and embedded in a solid medium to allow for thin sectioning. Paraffin wax is a common embedding medium because it is relatively inexpensive, easy to handle, and allows for good preservation of cellular detail.

The process involves dehydrating the tissue, typically with a series of alcohol washes, and then infiltrating it with molten paraffin wax. The tissue is then placed into a mold filled with more molten wax, which solidifies upon cooling, creating a paraffin block containing the tissue. A parafiinilevyyn is a thin slice, or section, cut from this solidified paraffin block. These sections are usually made using a microtome, a specialized instrument that can cut slices as thin as a few micrometers.

These thin sections are then mounted onto glass slides, deparaffinized to remove the wax, and stained with various dyes. The stains highlight different cellular components, making them visible under a microscope. Parafiinilevyyn is a fundamental step in preparing biological samples for microscopic analysis and diagnosis in fields such as pathology and research. The quality of the parafiinilevyyn directly impacts the ability to observe and interpret the tissue's microscopic features accurately.
