cryogenics Is It Worth Waiting For     Imagine being frozen in sentence to escape a deadly illness, then gettingwarmed when a cure is found. There is question on whether cryogenic methodsshould be used. To richly understand cryogenics a knowledge of cold, backgroundinformation on some branches of cryogenics, some problems with cryopresevation,and different peoples views towards cryogenics is needed."Cold is usually considered incompatible to mankind. Most people hate cold andwith reasons." If not careful, cold rout out be deadly to animal and human life, butit stomach as well help cure, because cold bodies perform functions slower (Kavaler 16-17). Measurement of temperature is extremely all important(predicate) in cryogenics and thetemperatures must be exact. The standard for scientific temperature amountis the kilobyte scale. On the Kelvin scale absolute zero has a value of zerodegrees on the thermometer. In theory no aggregate can be lowered to or belowzero degrees Kelvin or absolute zero. Temperatures in cryobiology range fromzero degrees Celsius--water freezes--to just in a higher place negative two hundred andseventy three point xvi degrees Celsius--absolute zero. The word" cryogenics" comes from the Greek word kryos meaning cold (CryogenicsRaintree 127, Kavaler 16). The science of cryobiology was archetypical recognized inthe early nineteen sixties. Cryobiology is the moot of the effects ofextremely low temperatures on living animals and plants. The chief upkeep 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 kept liveborn for very long periods of time in a stateof hang up animation. Almost immediately after rapid thawing, the frozencells regain conventio nalism activity. Cooling of the body causes a loss of feeling,therefore it can be used as anesthesia in surgery. Since certain drugs dontaffect 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, jumble, and blood thatwere speedily frozen can be stored in banks for later use. Then skin can begrafted to burn victims and eye corneas can replace dishonored ones. Thanks toCryobiology blood can be frozen and stored for indefinitely for some years asopposed to only three weeks as it was in the first place cryogenic technology was used.Surgeons can use a cryoscapel, freezing tips, to tone down or destroy tissue withgreat accuracy and little bloodbath (Cryogenics Academic 350, CryobiologyWorld Book 929).
