Cryogenics Is It Worth Waiting For     Imagine being frozen in time to escape a deadly illness, then getting change when a cure is found. There is question on whether cryogenic rulesshould be used. To fully understand cryogenics a knowledge of stale, background randomness on some branches of cryogenics, some problems with cryopresevation,and different peoples views towards cryogenics is needed."Cold is unremarkably considered hostile to mankind. Most people hate frore andwith reasons." If not careful, cold toilette be deadly to animal and human life, butit crumb also help cure, because cold bodies perform functions slower (Kavaler 16-17). Measurement of temperature is super important in cryogenics and thetemperatures must be exact. The standard for scientific temperature measurementis the Kelvin scale. On the Kelvin scale absolute nonentity has a value of postal codedegrees on the thermometer. In theory no substance can be lowered to or belowzero degrees Kelvin or absolute zero. Temperatures in cryobiology range fromzero degrees Celsius--water freezes--to just now above negative two hundred andseventy three degree sixteen degrees Celsius--absolute zero. The word"Cryogenics" comes from the Greek word kryos meaning cold (CryogenicsRaintree 127, Kavaler 16). The science of cryobiology was first recognized inthe early xix sixties. Cryobiology is the study of the effects ofextremely low temperatures on living animals and plants. The main(prenominal) concern incryobiology is to preserve living matter for future use. This method can alsobe called cryopreservation. Cryotherapy is the use of extreme cold in treatment.The first trials of cryotherapy proved with great results (CryobiologyComptons 1, McGrady 97).     Frozen cells can be unplowed alive for very long periods of time in a call forthof suspended animation. Almost immediately after rapid thawing, the frozencells get normal activity. Cooling of the body causes a loss of feeling,therefore it can be used as anesthesia in surgery. Since certain drugs tire outtaffect healthy cells at low temperatures, the drugs can be safely used againstcancerous tumors in the body. Cryogenics also helps in the preservation andstorage of human tissues. Tissues such as eye corneas, skin, and neckcloth thatwere rapidly frozen can be stored in banks for later use. therefore skin can begrafted to burn victims and eye corneas can substitute damaged ones. Thanks toCryobiology blood can be frozen and stored for indefinitely for many years asopposed to only three weeks as it was before cryogenic technology was used.Surgeons can use a cryoscapel, freezing tips, to deaden or destroy tissue withgreat accuracy and light bloodshed (Cryogenics Academic 350, CryobiologyWorld Book 929).
