Boffins create zombie dogs
By Nick Buchan of NEWS.com.au June 27, 2005
SCIENTISTS have created eerie zombie dogs, reanimating the canines after several hours of clinical death in attempts to develop suspended animation for humans.
US scientists have succeeded in reviving the dogs after three hours of clinical death, paving the way for trials on humans within years. Pittsburgh's Safar Centre for Resuscitation Research has developed a technique in which subject's veins are drained of blood and filled with an ice-cold salt solution.
The animals are considered scientifically dead, as they stop breathing and have no heartbeat or brain activity.
But three hours later, their blood is replaced and the zombie dogs are brought back to life with an electric shock.
Plans to test the technique on humans should be realised within a year, according to the Safar Centre.
However rather than sending people to sleep for years, then bringing them back to life to benefit from medical advances, the boffins would be happy to keep people in this state for just a few hours,
But even this should be enough to save lives such as battlefield casualties and victims of stabbings or gunshot wounds, who have suffered huge blood loss.
During the procedure blood is replaced with saline solution at a few degrees above zero. The dogs' body temperature drops to only 7C, compared with the usual 37C, inducing a state of hypothermia before death.
Although the animals are clinically dead, their tissues and organs are perfectly preserved.
Damaged blood vessels and tissues can then be repaired via surgery. The dogs are brought back to life by returning the blood to their bodies,giving them 100 per cent oxygen and applying electric shocks to restart their hearts.
Tests show they are perfectly normal, with no brain damage.
"The results are stunning. I think in 10 years we will be able to prevent death in a certain segment of those using this technology," said one US battlefield doctor.

This could totally revolutionize emergency trauma care. Imagine instead of trying to rush a person to the hospital as quick as possible, purposefully kill and perserve the person for later revival after the damage is repaired.
Oh, but wait, this has to be an exageration or some sort of lie, because I can only find this story on a Newscorp website.

Too bad they would be severely brain damaged.

The title is misleading, as the dogs were revived without any apparent side effects, i.e they did not turn into zombies

I saw that, however, I doubt that is entirely true.
I suspect that a dog can sustain serious brain damage and still behave normally, as most of a dog's actions are instinctive and require little brainpower or thought or reasoning. This is not so with humans for higher primates.

Well, since you are not privy to what battery of tests were performed on these revived canines, your opinion doesn't amount to a hill of beans.

I don't get it. I wish doctortobe was here to offer an opinion on this, but without blood, how do the cells oxygenate? Without oxygen doesn't the brain and other organs die? How long can these dogs be "dead" before they must be revived? Don't get me wrong, this is really facinating, we could be seeing major advances in cryogenics here, but it seems to good to be true.

You concidered opinion is noted , but - Quote:

I've seen no evidence in your posts here or in the past that you any more qualified to comment on this than I am . Care to elaborate ?

Eventually the cells would die due to a lack of oxygen, but since the duration of the test was only 3 hours and the temperature of the solution that replaced the blood was 3oc, the metabolic function of the cells was slowed considerably, thus the need for oxygen was greatly reduced.

Oh - the dogs were not killed afterall , they were simply chilled and placed into a hypothermic coma , then revived.
Maybe you should check the definition of a zombie.
If you are going to post headlines , how about making them reasonably accurate rather than misleading.
By the way there are precedents of humans being similarly revived , expecially after suffering horrendous battlefield injuries in Arctic conditions , where their falling into hypothermic coma saved them.
