Cryotherapy
Technique using liquid nitrogen, for example, to freeze warts and precancerous lesions.
SIMILAR TERMS--------------------------------------
Cryo-electron microscopy
An electron microscopic technique that involves freezing the biological sample in order to view the sample with the least possible distortion and the fewest possible artifacts. Abbreviated as cryo-EM.
Cryo-EM
Cryo-electron microscopy.
Cryocardioplegia
Paralysis of the heart by cold (hypothermia).
Cryoglobuliaemia
Phenomenon of precipitation of immunoglobulins in serum on exposure to cold. Associated with vasculitis and Raynaud's phenomenon.
Cryoglobulin
"An abnormal blood protein that has the unusual properties of precipitating from the blood serum when it is chilled (hence the ""cryo-"") and redissolving when it is rewarmed. Cryoglobulins are gamma globulins with a molecular weight of approximately 200,000. "
Cryoglobulinemia
The presence in blood of abnormal proteins called cryoglobulins that, by definition, have the unusual properties of precipitating from the blood serum when it is chilled and redissolving upon rewarming. (Cryoglobulins are gamma globulins with a molecular weight of approximately 200,000.)
Cryophobia
An abnormal and persistent fear of cold, including cold weather and cold objects. Sufferers from cryophobia experience anxiety even though they realize their fear is irrational. To avoid cold, they may live in a warm climate, dress more warmly than necessary, stay indoors on cold days, and avoid cold foods and ice cubes.
Cryopreservation
To preserve by freezing. Bone marrow harvested for an autologous BMT, for example, is cryopreserved.
Cryoprobe
A surgical probe, a long slender pointed surgical instrument, used to apply extreme cold to tissues.
Cryoprostatectomy
Freezing of the prostate through the use of liquid nitrogen probes guided by transrectal ultrasound of the prostate.
Cryoprotectant
A chemical component of a freezing solution used in cryopreservation (the process of cooling and storing cells, tissues, or organs at very low temperatures to maintain viability). The purpose of the cryoprotectant is to help protect what is being frozen from freeze damage.
Cryostat
A chamber that can maintain very low temperatures. Medical laboratories use a cryostat to preserve frozen tissue samples while a microtome, an extremely sharp cutting instrument mounted inside cryostats, slices the tissue into pieces thin enough to be observed under a microscope. The sliced piece must be so thin as to look nearly transparent. A pathologist, a laboratory doctor trained to identify evidence of disease in microscopic structures, then examines the slice to confirm or rule out the presence of a disease, such as cancer. Use of frozen tissue samples enables physicians to examine tissue and diagnose its condition more quickly than if the tissue had been preserved without freezing.
Cryosurgery
The use of extreme cold (usually liquid nitrogen) to destroy unwanted tissue (warts or cataracts or skin cancers).
Cryothalamotomy
A surgical procedure in which a supercooled probe is inserted into a part of the brain called the thalamus in order to stop tremors.
