Outline of Final Research Achievements |
The present study was designed to develop a method for inducing hypothermia, which is equivalent to hibernating animals, in non-hibernators, to apply the hypothermic condition as a novel hypothermic therapy. In hamsters, extreme hypothermia with normal heartbeats can be forcibly induced by cooling the animals under isoflurane inhalation and stopping the inhalation when their body temperature was dropped about 25C. Application of the method to rats successfully induced hypothermia without accompanying cardiac arrest. In addition, we examined mechanism underlying cold-tolerant nature of the hamster heart, and found that regulation of cold-shock protein expression may have a beneficial role.
