Super-low Temperature Keeps Monkey’s Brain

Through more than a year’s concerted efforts, Prof. JIANG Jiyao at the Department of Neurosurgery, the Renji Hospital, an affiliate to the Shanghai No. 2 Medical School, and a study team headed by Prof. XU Wei, Division of Neurosurgery, No. 2 Hospital under the Kunming Medical School, have recently made a revival experiment on five monkeys, using a selective super deep low temperature technique (16C). All the five monkey subjects have survived the experimental operation.

Researchers believe that the experiment has provided animal based experimental evidences for handling emergency patients suffering heart stop or acute brain blood shortage. The new technique also creates a promising perspective for performing brain operations in a bloodless manner. Researchers found that, the full-body super deep low temperature technique ( lower than 18C) may also bring down the brain temperature to 18C or below. However, the full body application can easily cause damages to heart and lungs in the process of revival. The selective low temperature brain technique can avoid the possible damages caused by a full-body application to heart and lungs. Researchers also ascertain that the lower brain’s temperature, the better protection for brain cells.



The alternative and (and usual) spelling for the researchers name is "YANG Xiao".
Can anyone tell me where the above has been published?

Unfortunately the report doesn't state how long the brain was maintained at that temperature, and what the perfusion conditions were. In particuar, the press release isn't clear whether the model involved continuous perfusion or circulatory arrest.

Progress in this little-known area of medicine (surgical deep hypothermia) is always interesting because the initial phases of cryonics involve passing through this condition. But this report is so vague that its significance is difficult to evaluate.

For background, the world record for recovery of whole large animals from hypothermic circ arrest is 3 hours at 0 degC, set back in 1986

CAN A HUMAN BE PUT INTO CRYONICS WITHIN TWELVE HOURS OF DEATH AND BE BROUGHT BACK TO LIVING CONDITIONS. HAS IT BEEN TESTED.

I HAVE CONSIDERED CRYONICS AND CAME TO A PROBLEM IN MY MIND THAT IT COULD BE USED AS A FORM OF ESCAPE. A THOUGHT OF IS IT A FORM OF SUICIDE.
