The coolest idea in stroke (中风) treatment is refrigeration. Yes, cold is hot.
Many doctors believe they can reduce the lasting forever damage after a stroke by quickly dropping patient body temperatures for a day or two, basically storing their brains on ice.“It’s like putting food in the refrigerator. It doesn’t go bad. You slew down all the processes,” says Dr David Tong of Stanford University.
The approach is new, but the understanding behind it—that cold protects the brain like a fridge keeps tomatoes—has been recognized for centuries.
Everyone knows a story of a child who falls into an icypond is fished out after 45 minutes and then is warmed up and is perfectly OK. The cold water stops biological processes that ordinarily would kill brain cells almost immediately. Performed occasionally in surgery (外科), cooling the sick was still considered too risky and unpleasant and impractical for the 700,000 strokes in the US each year. Instead, researchers put their faith in medicines. But that goal has been all too difficult to catch as dozens of supposedly brain-protecting drugs failed testing over that past ten years.
Now, supported by fresh science and new technology, doctors are looking again at cold. They hope soon to prove it a workable and valuable first step for treating stroke victims.
In theory, doctors say, cooling the head should slow or even stop the destruction of weak brain cells. Several experiments have indictated this might be the case.
Currently the whole body must be cooled, using air-cooled blankets and sometimes packing in ice or robbing with alcohol.
Deep-cooling is already sometimes used to minimize damage during some surgery. It was also the way in the early days of open-heart surgery before the invention of the movement of blood machines that pump the blood while the heart is stopped. For these operations, doctors often took patients to such low temperatures that dangerous complications (并发症) occurred, such as irregular heartbeats and blood clotting (凝结成块).
1.The writer thinks that refrigeration in stroke treatment ________.
[ ]
A.is a wonderful method
B.will produce high temperature
C.has been used for centuries
D.is too simple to carry out
2.In the fourth paragraph the writer gives us an example to ________.
[ ]
A.show us how clever the boy is
B.explain how the treatment works
C.make us believe that children like fishing
D.tell us to do the experiment ourselves
3.In the USA, cooling, the sick in surgery ________.
[ ]
A.is popular but risky for patients
B.has been proved to be safer than brainprotecting drugs
C.is considered helpful for treating stroke patients
D.is still considered dangerous and costs more money
4.It can be referred from this passage that
A.doctors should treat all kinds of patients in an old way
B.doctors should treat all kinds of patients in a strange way
C.medical science is developing with other sciences
D.medical treatment is based on theory
5.From the last part of this passage, we know that ________.
[ ]
A.doctors can’t operate on a patient if his body temperature is high
B.doctors should try their’ best to reduce a patient’s temperature
C.a patient’s body can work normally without the movement of his blood
D.a patient’s body temperature can’t be reduced too low
