A giant panda from the Beijing Zoo has been saved by a transfusion of blond from two black bears. But it's still under special care , according to the Beijing Zoo.
Yong Liang, two years old , is the first giant panda raised from birth in the zoo. Last month zoo keepers found the panda was suffering from serious anaemia（贫血）, calling for urgent（紧急的） blood transfusion.
　　The best way , according to zoo's experts , to save Yong Liang from anaemia would have been to transfuse blood from another panda. But it was the breeding season for giant pandas, making such a transfusion very difficult.
But the experts found that there exists a close consanguinity （血缘） between giant pandas and black bears , and so they decided to try to take blood from black bears in the zoo and transfuse it to Yong Liang.
With the help of hospitals and the Beijing Blood Donor Station, they made an experiment which proved that the red blood cells in the blood of black bears can be used.
On the afternoon of February 15th the first red blood cell transfusion was given to the giant panda, from 600m1 of black bear blood. Immediately the young panda started to recover.
