Imagine being frozen in time to escape a deadly illness, then getting warmed
when a cure is found. There is question on whether cryogenic methods should be
used. To fully understand cryogenics a knowledge of cold, background information on
some branches of cryogenics, some problems with cryopresevation, and different
peoples views towards cryogenics is needed.
"Cold is usually considered hostile to mankind. Most people hate cold and with
reasons." If not careful, cold can be deadly to animal and human life, but it can also
help cure, because cold bodies perform functions slower (Kavaler 16-17).
Measurement of temperature is extremely important in cryogenics and the temperatures
must be exact. The standard for scientific temperature measurement is the Kelvin
scale. On the Kelvin scale absolute zero has a value of zero degrees on the
thermometer. In theory no substance can be lowered to or below zero degrees Kelvin
or absolute zero. Temperatures in cryobiology range from zero degrees Celsius--water
freezes--to just above negative two hundred and seventy three point sixteen degrees
Celsius--absolute zero. The word "Cryogenics" comes from the Greek word "kryos"
meaning cold ("Cryogenics" Raintree 127, Kavaler 16). The science of cryobiology was
first recognized in the early nineteen sixties. Cryobiology is the study of the effects of
extremely low temperatures on living animals and plants. The chief concern in
cryobiology is to preserve living matter for future use. This method can also be called
cryopreservation. Cryotherapy is the use of extreme cold in treatment. The first trials
of cryotherapy proved with great results ("Cryobiology" Comptons 1, McGrady 97).
Frozen cells can be kept alive for very long periods of time in a state of
"suspended animation." Almost immediately...
