From Cryonics May 1987
THE DOG AND PHONY SHOW
An event doesn't exist until the media announces it. Once
the media announces it, it is an event whether or not it exists. — Jerry Rubin,
1960's Berkeley radical
Unless you've been living in a cave recently, you've no
doubt heard the story and seen the headlines: "Frozen Dog A Hot Topic," "Dog Spunky
After It's Frozen In Test," "Beagle Placed Into Suspended Animation Lives To Wag
About It" Some of you even called to inquire "if ALCOR was aware of the American
Cryonics Society/Trans Time breakthrough?"
THE REAL STORY
So, what's the story?
The media has gone wild but what does it mean? To careful readers of CRYONICS
the answer(s) to that question will be obvious. To newer readers the answers may
not seem so clear. Hopefully all of our readers, new and old, will profit from
a brief review.
First of all, the facts. ACS researcher Paul Segall and his associates
carried out a total body washout on a beagle dog, flushing most of the blood (down
to a hematocrit of about 4%; the hematocrit is the percentage of blood which is
red cells, in a dog about 48% is normal) and cooling it to 3°C. They held the
animal at that temperature for 20 minutes and then rewarmed it, reinfused blood,
and restored heartbeat and breathing. The dog is now alive and in apparent good
health. Those are the facts and they are not in dispute.
Now for the hype. As
the newspaper headlines throughout this indicate, this work has been billed as
a "major medical advance." It isn't. First of all, as most readers of CRYONICS
will know, ALCOR has been cooling dogs down to the same temperature, doing a complete
blood washout (hematocrit less than 1%!), continuously perfusing the animals for
4 hours and then rewarming them to long term survival. ALCOR's perfusate is a
far more sophisticated one than the ACS solution, and ALCOR has not yet established
the upper limit on how long this solution can be used to maintain animals in such
a chilled, bloodless state. That is a major advance, if not a "breakthrough."
But even beyond ALCOR's work, as long as 20 years ago researchers were washing
out dogs and even humans using techniques very similar to the ones Dr. Segall
et al employed. In 1972 Gerald Klebanoff of Lackland Air Force Base successfully
treated Stage IV hepatic coma by washing all the blood out of human patients
and deep cooling them. Klebanoff was also successful at extended bloodless perfusion
of dogs, in some instances recovering animals from up to 8 hours of continuous
bloodless perfusion (J. Surgical Research, 19, 13-19 (1972)). While Klebanoff
carried out his work at temperatures a few degrees warmer than Dr. Segall has,
the difference is not clinically or medically significant. As far as temperature
is concerned, recent work by Haneda et al (Cryobiology, 23, 483-494 (1986)) has
achieved three hours of cold circulatory arrest at 3°C using dogs. Segall's work
is NOT any kind of medical, scientific, or technological breakthrough. What it
is is a lot of hype, pure and simple.
WHY?
Many of our readers have called to
ask "How did this come about?" How did it happen that Segall and his associates
were able to capture the attention of the national media and be taken as seriously
as they have been? It's a complex story, and we can only summarize it here. It
starts with Dr. Segall's Ph.D. and his connection with the University of California
at Berkeley, one of the world's most prestigious schools. With these connections,
Segall was able to get his paper sponsored for presentation at the Federation
of American Societies for Experimental Biology (FASEB) annual meeting which was
held in Washington D.C. in late March. FASEB is one of the most prestigious scientific
bodies in the United States. It is important to understand this because someone
in FASEB who was unfamiliar with the field of cryobiology in general, and bloodless
hypothermic perfusion in particular, did not realize that Dr. Segall's work was
neither new nor of any particular importance. Not only was Dr. Segall's abstract
accepted, it was selected by FASEB for special media attention and Dr. Segall
was encouraged to write up a media summary. This was released at a FASEB press
conference. Perhaps most shocking of all is that this was done by FASEB on the
basis of only one experiment. Normally a scientific paper claiming a "breakthrough"
of this type would need the procedure performed on at least five animals before
the credibility of the paper is not questioned.
MEDIA EXTRAVAGANZA
The result
was a chain reaction of major media attention. Dr. Segall's work was featured
on the front pages of many newspapers across the country, he was given a short
interview by Jane Pauley on Good Morning America and was subsequently featured
in major national publications such as People magazine and National Enquirer.
At the time of this writing we have been given to understand that both Time and
Newsweek will also be featuring reportage on the "miraculous frozen dog."
The
coverage of Segall's work was typical of the publicity that ACS generates. There
were no careful distinctions made between deep chilling (hypothermia) and freezing
(where body water is converted to ice). And Segall, despite extensive knowledge
of both Klebanoff's and ALCOR's far more extensive dog washout work, failed to
properly cite or credit these investigators. At the FASEB presentation Segall
et al also announced hydroxyethyl starch (HES) as a major discovery in hypothermic
preservation of organisms, citing its effectiveness in eliminating fluid accumulation
in the lungs (pulmonary edema) and other tissues, without crediting Jerry Leaf
and the ALCOR research team who were the first (by several years) to discover
this!
In the days following the initial FASEB press release we understand that
Drs. Segall, Waitz, and Sternberg gave over 100 radio and TV interviews. We have
heard and seen a number of these. At no time did Dr. Segall "set the record straight"
with respect to the real (in)significance of the work by putting it into proper
perspective and crediting previous investigators.
Of course, to credit previous
investigators would amount to discrediting the importance of the work that Segall
and his associates had conducted. What would the scientific community and the
media think if they knew that other investigators had cooled animals to the same
temperature, perfused them for four hours, and what's more, perfused them with
an intracellular solution (one which mimics the electrolyte and osmotic environment
inside the cells) which has the potential of allowing far longer periods of ice-cold
storage than the 4 hours achieved so far?
In the February issue of CRYONICS Mike
Darwin noted that "the glamour acts would soon be on the scene." He appears to
have been right on target. While the possibility of this kind of thing is hardly
news to ALCOR Officers and Directors we confess to being somewhat demoralized
by it. Yes, we knew that this kind of thing was going to happen sooner or later,
and yes, we know it's going to continue to happen.
Nevertheless, it is irritating
and demoralizing. It's demoralizing because it means that many innocent people
will be misled about the real prospects for cryonics and cryobiology. It's demoralizing
because it will no doubt confirm in the minds of our critics their worst fears
about cryonics: that we are not committed to the truth or to the responsible use
of science, but rather that we are willing to do anything, including using hype
or deception, to achieve our ends.
The problem with hype and deception in
an enterprise like cryonics is that they simply won't work. Undoubtedly, in the
short run in many undertakings they can "work" quite well. As long as you can
get into and out of the system before you get caught (and there's a steady supply
of suckers who can't communicate with each other), this approach can work remarkably
well. Of course, the problem is that this approach to life rather limits what
you can do.
Cryonics is the ultimate in long term efforts. In fact, what distinguishes
cryonics from most other human endeavors is the expansion in time scale it represents.
Very, very few human undertakings have called for major, costly, contemporary
action based almost completely on a long- term evaluation of our potential future
capabilities. Unfortunately for cryonicists, almost no one living today is capable
of seeing far enough into the future or of taking seriously what might happen
50 or 150 years from now and to understand the utility and importance of our message.
For most people the inability to function in a cryonicist's time scale blinds
them to the rationality and the immense possibilities of what we are doing.
This
is a critical point. A good illustration is to look at what are now considered
abnormalities in human behavior which hinge on time scale problems. Some people
live from moment to moment, unable to plan for anything -- sometimes not even
able to plan far enough in advance to figure out where their next meal is coming
from or where they'll spend the night. Some people rob banks or shoplift simply
because the only thing they can hold in their heads for any length of time is
immediate gratification. This is a devastating handicap for an individual embedded
in a society in which the normal time scale for human planning is a period of
decades and encompasses things like buying a home with a 30-year mortgage, sending
children through college, and engaging in activities like space exploration. Cryonics
represents another expansion in time scale which differentiates us from the rest
of the world as greatly as a vagrant or hold-up man is differentiated from contemporary
society.
This discussion is relevant to the misleading press surrounding the ACS/Segall
affair because the same kinds of issues are at stake. In the long term, distortive "sizzle-type" marketing is an invitation to disaster. Because of the long time
period between action and feedback in cryonics it is especially important to pursue
it carefully. In almost no other human undertaking is there a greater potential
for fraud. The corollary to this observation must be extreme vigilance and conservatism
in undertaking cryonics. We simply cannot afford a misstep. This would be true
even if we lived in a world absent of bureaucrats and attorney generals. If we
are to be taken seriously in such an inherently suspicious undertaking as cryonics,
we must act and be serious, ever mindful of the tremendous responsibility we bear
to both ourselves and others. In short, what this means is that cryonics must
be handled and promoted in a fundamentally new way, with the focus being more
on the long term consequences and objectives to a greater extent than has been
the case with any other human endeavor to date.
Yet another demoralizing thing
about the Segall affair is what it says about the world we live in. Those of us
who are on the "inside," who have worked hundreds of grueling hours on the dog
total body washout work here at ALCOR, doing animal after animal and carefully
exploring every aspect of the physiology and biochemistry of the model we have
been using, find ourselves stunned. We knew, in principle, that this kind of thing
was possible. We even knew it was likely. But nothing prepared us for the emotional
reality.
And finally, there is the issue of what the long term consequences of
this will be for cryonics as a whole. Hype and distortion have a way of being
discovered; if and when this one wears thin will we cryonicists be in any position
to defend ourselves against charges of fraud or to argue for rational government
regulation when it is thrust upon us? Even worse, will we be able to prevent it
when angry citizens call for all cryonics to be prohibited by law?
At this point,
just about the only things we feel sure about are that when judgment day comes
(and it will come), the media will be there too. Next time, we guarantee it won't
be nearly so much "fun."
