It’s difficult for doctors to help a person with a hurt brain.
36 enough blood, the brain can live only three to five minutes. Usually doctors can’t fix the hurt
37 such a short time.
Dr Robert White thinks he knows a
38 of help. He thinks doctors should make the hurt brain
39 to live for 30 minutes without blood. This gives the doctor
40 time to do something for the brain. Dr White experimented his
41 on fifteen monkeys.
42 he taught them to do different jobs. Then he operated on them. He made the monkeys’ blood go
43 a machine. When the brains’ 44 was 10℃, he stopped the blood to the brain. After 30 minutes, he turned the blood back on. He
45 the blood again. After their operations, the monkeys were almost
46 before. They were healthy and busy. Each one could still do the job the doctor
47 them.
Dr White’s idea works well on monkeys. He thinks it will work on
48 . He think it will help with heart problems. A person
49 die when his heart stops; doctors can
50 it again. The problem comes: when the brain is without blood for about 5 minutes, it
51 . If doctors start the heart again after 5 minutes, the person has
52 body but a dead brain. Maybe in the future, doctors will
53 Dr White’s idea. When the person’s heart stops the doctor will
54 cool the brain. They will have 30 minutes to start the heart again. Maybe there will be no
55 the brain.
