2nd LLE Flashcards
Used for delicate specimens and frozen tissue sections because it prevents fragmentation of tough and friable tissues
Gelatin impregnation
Embedding mold recommended for busy routine laboratories
Plastic ice trays
Method of paraffin wax impregnation gives the fastest result
Vacuum processing
Melting point of wax commonly used for routine procedures
56 C
Process by which tissue is arranged in precise position in the mold before embedding
Orientation
A series of interlocking plates resting on a flat metal base
Compound embedding unit
Gives superior results for a light microscopic studies in hard tissues like undecalcified bones
Plastic embedding
Acrylic plastic is for?
Light microscopy
Polyesters plastic is for?
Electron microscopy
At what temperature should a paraffin oven be maintained when used for impregnation
2-5 centrigade above melting point
Melting point of highly purified paraffin and synthetic plastic polymers
56-57 C
Most rapid clearing agent suitable for urgent biopsies
Xylol
It causes the minimum shrinkage of tissues but dissolves aniline dyes and celloidin
Clove oil
Recommended for embryos and very delicate specimen
Cedarwood oil
Considered carcinogenic and may damage the bone marrow resulting in a plastic anemia
Benzene
Carbon tetrachloride has properties similar to?
Chloroform
Recommended for fibroid and decalcified tissues
Chloroform
