Old rats rejuvenated after injection of young blood

"The study showed that 18-month-old mice who had been received eight transfusions of young blood had a much easier time making it through the a watery maze than the old mice who had not received any transfusions. 

"They were 18 months old but they were acting much younger, like a four to six-month-old," said Dr. Villeda, one of the lead researchers.

The study also demonstrated that older mice who had received the blood transfusions also began to grow new synopses in their brain--connections which are essential for the retention of memory.

Last year, the same Stanford researchers demonstrated that injecting young mice with old blood led to mental deterioration in the rodents.

This research led them to undertake this more recent experiment to see whether the reverse could be true.

Moving forward, it is unlikely that a vial of youthful blood itself will become the treatment for aging. Instead, scientists say that the new challenge is to identify what compounds inside young blood carry this rejuvenating effect--potentially allowing researchers to extract or replicate these particularly chemicals."

Apparently, the late North Korean dictator, Kim Jong-Il has been doing this too...
