18.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 anemia(贫血),calling for urgent blood transfusion.
The best way,according to the zoo's experts,to save Yong Liang from anemia would be to transfuse blood from another panda.But it was the breeding season for giant pandas,and such a transfusion would be very difficult.
But the experts found that there exits 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-about 600 ml blood from the black bear.Immediately the young panda started to recover.
