Medical uses of cryogenics
Low temperature have been used for long term preservation of blood, sperms, bone marrow and tissues.


Cryosurgery

The cryogenic methods used to destroy cells called cryosurgery. It has several advantages

(1) cause a little bleeding

(2) the volume of the tissue destroyed can be controlled.

(3) Little pain because low temperature desensitize nerves.

(4) Very short recovery.

One of the first uses of cryosurgery is in the treatment of Parkinson disease. (Shaking palsy). This disease cause uncontrolled tremors in the arms and legs. It is possible to stop it by destroying parts of the thalamus of the brain that controls nerve impulse to the other part of the nervous system. The treatment undergoes while the patient is conscious.

Successful results were obtained in more than 90% of the cases but the development of new drugs makes the use of cryosurgery for medically untreatable Parkinson disease. Other common uses of cryosurgery are in tumors and warts.Cryosurgery is used in several types of eye surgery,

(1) In retina detachment

(2) the cryosurgical extraction of the lens.
