Decalcification Flashcards
T/F
Atherosclerotic plaque don’t need decalcification
False
Sternum needs to be decalcified
True
Deposition of calcium in dying tissue
Dystrophic calcification
Deposition of calcium in normal tissues due to elevated serum levels of calcium
Metastatic
What kind of deposition: rheumatic heart disease
Dystrophic
Give the decalcifying agents
ACIE
ACID
CHELATING AGENTS
ION-EXCHANGE RESIN
ELECTROLYSIS
Most commonly used chelating agent
EDTA (versene)
Commonly used decalcifying agent
Nitric acid
This agent combine with the calcium ions and other salts to form weakly dissociated complexes and facilitate removal of calcium
Cheating agent
Removes calcium from acid-containing decalcifying solutions
Ions exchange resin
Use electrode to remove calcium.
Electrophoresis
Methods used to measure extent of decalcification
Radiological
Chemical (calcium oxalate)
