      The reported kidney cryopreservation breakthrough is a non-event.  With 
      sufficient cryoprotectant to prevent freezing damage, any kidney cooled to
      liquid nitrogen temperature will transiently produce urine when 
      reperfused with blood even if every cell in it is doomed to die from 
      cryoprotectant toxicity and chilling injury.  Years ago 21CM transplanted 
      a rabbit kidney (much larger than a rat kidney) after cooling to liquid 
      nitrogen temperature, and the animal produced urine for several days 
      before the kidney ultimately failed.  We reported this result off-handedly
      at a recent cryobiology meeting.  We don't believe that results of this 
      nature warrant a paper, let alone a press release.
