Cryogenics: Is It Worth Waiting For
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 after rapid thawing, the frozen
cells regain normal activity. Cooling of the body causes a loss of feeling,
therefore it can be used as anesthesia in surgery. Since certain drugs don’t
affect healthy cells at low temperatures, the drugs can be safely used against
cancerous tumors in the body. Cryogenics also helps in the preservation and
storage of human tissues. Tissues such as eye corneas, skin, and blood that
were rapidly frozen can be stored in “banks” for later use. Then skin can be
grafted to burn victims and eye corneas can replace damaged ones. Thanks to
Cryobiology blood can
