Cryogenicss: Is It Worth Waiting For
Imagine being frozen in clip to get away a deathly unwellness, so acquiring
warmed when a remedy is found. There is inquiry on whether cryogenic methods
should be used. To to the full understand cryogenies a cognition of cold, background
information on some subdivisions of cryogenies, some jobs with cryopresevation,
and different peoples positions towards cryogenies is needed.
& # 8220 ; Cold is normally considered hostile to mankind. Most people hate cold and
with reasons. & # 8221 ; If non careful, cold can be lifelessly to animal and human life, but
it can besides assist remedy, because cold organic structures perform maps slower ( Kavaler 16-
17 ) . Measurement of temperature is highly of import in cryogenies and the
temperatures must be exact. The criterion for scientific temperature measuring
is the Kelvin graduated table. On the Kelvin graduated table absolute nothing has a value of nothing
grades on the thermometer. In theory no substance can be lowered to or below
nothing grades Kelvin or absolute nothing. Temperatures in cryobiology scope from
nothing grades Celsius & # 8211 ; H2O freezes & # 8211 ; to merely above negative two hundred and
70 three point 16 grades Celsius & # 8211 ; absolute nothing. The word
& # 8220 ; Cryogenics & # 8221 ; comes from the Grecian word? kryos? intending cold ( ? Cryogenicss?
Raintree 127, Kavaler 16 ) . The scientific discipline of cryobiology was first recognized in
the early 19 1960ss. Cryobiology is the survey of the effects of
highly low temperatures on life animate beings and workss. The main concern in
cryobiology is to continue living affair for future usage. This method can besides
be called cryopreservation. Cryotherapy is the usage of utmost cold in intervention.
The first tests of cryotherapy proved with great consequences ( ? Cryobiology?
Arthur comptons 1, McGrady 97 ) .
Frozen cells can be kept alive for really long periods of clip in a province
of? suspended animation. ? Almost instantly after rapid melt, the frozen
cells regain normal activity. Cooling of the organic structure causes a loss of feeling,
therefore it can be used as anaesthesia in surgery. Since certain drugs wear? T
affect healthy cells at low temperatures, the drugs can be safely used against
cancerous tumours in the organic structure. Cryogenicss besides helps in the saving and
storage of human tissues. Tissues such as oculus corneas, tegument, and blood that
were quickly frozen can be stored in? Bankss? for subsequently usage. Then skin can be
grafted to fire victims and oculus corneas can replace damaged 1s. Thankss to
Cryobiology blood can be frozen and stored for indefinitely for many old ages as
opposed to merely three hebdomads as it was before cryogenic engineering was used.
Surgeons can utilize a cryoscapel, stop deading tips, to dampen or destruct tissue with
great truth and small bloodshed ( ? Cryogenics? Academic 350, ? Cryobiology?
World Book 929 ) . Scientists use a
liquid gas called liquid N to stop dead
and shop cells. Some could jobs besides occur in cryogenies. If cells are
non frozen fast enough they will detonate and decease. Many biological reactions may
take topographic point in temperatures every bit low as negative nine grades Celsius. And, ice
crystals, which form every bit temperatures every bit low as negative one hundred and thirty
grades Celsius, will destruct the frozen cells ( Allen 38, ? Cryobiology? Gale
1029 ) .
Following are the positions of two people involved with cryogenies. Mr.
Young, a biological science instructor with a working cognition of cryogenies, thinks
cryobiology should be used to continue endangered species. He doesn? T see the
engineering for stop deading a whole organic structure but possibly organic structure variety meats in the close hereafter.
Mr. Young believes the money that would be needed to better the engineering
could be better spent, which is a contention in itself. If given a opportunity Mr.
Young would come in his organic structure into cryopreservation for the benefit scientific discipline ( Young
interview ) . Whereas, an America On-Line & # 8211 ; AOL & # 8211 ; user with an involvement in
cryogenies feels when cryopreservation becomes a world for an full organic structure, if
people are willing and have the money, they should come in their organic structures into
cryopreservation. He thinks the daze of waking up in a new age of clip could
be unsafe to 1s mental wellness ( AOL interview ) .
Cryogenicss is of import because it could salvage and better life
in many ways. Cryopreservation, a subdivision of cryobiology, has the chief intent
of continuing populating affair, works or animate being, for future usage. Cryogenicss could
salvage the planet from extinction of endangered species. Scientist could salvage the
gametes, the sperm and the eggs, of endangered that can be fertilized and raised
when the environment is able to manage them. Cryopreservation should be used on
worlds who want to utilize it. Many people are willing to take the hazard of being
suspended or possibly even lost in clip for a opportunity to populate life once more.
