Suspended Animation In Mice Without Freezing

Predictions Market writes "Low doses of hydrogen sulfide, the toxic gas responsible for the unpleasant odor of rotten eggs, can safely and reversibly depress both metabolism and aspects of cardiovascular function in mice, producing a suspended-animation-like state that does not depend on a reduction in body temperature and include a substantial decrease in heart rate without a drop in blood pressure. The researchers measured factors such as heart rate, blood pressure, body temperature, respiration, and physical activity in normal mice exposed to low-dose (80 ppm) hydrogen sulfide for several hours. In all the mice, metabolic measurements such as consumption of oxygen and production of carbon dioxide dropped in as little as 10 minutes after they began inhaling hydrogen sulfide, remained low as long as the gas was administered, and returned to normal within 30 minutes of the resumption of a normal air supply. 'Producing a reversible hypometabolic state could allow organ function to be preserved when oxygen supply is limited, such as after a traumatic injury,' says the lead author of the study. 'We don't know yet if these results will be transferable to humans, so our next step will be to study the use of hydrogen sulfide in larger mammals.' The full report is available online."

    We can clone mice. We can cure mice cancer. We can put them into suspended animation, allowing them to live on into future generations (meaning they will probably be the first organic space pets). Something tells me that the rats of NIMH are already in the execution phase of some higher level plans with all the work we've managed to accomplish on their genetics.

      Looks like we can do more for mice, than for humans ... Its not just the rats of NIMH, Douglas Adams was right about the mice!

      Sure mice are making strides in the educational and scientific markets, but while you mouse people have been declaring it the "year of the mouse" for the last 10 years, squirrels have continued their predatory and monopolistic domination of both business and home rodent segments.

    If you have a suspended mouse, just check the ball hasn't got fluff on it.
