The first step to defeating an enemy is to pin down his exact identity and how he operates. Hypertension—chronic, abnormally raised blood pressure—causes heart attacks, strokes and a multitude of other【C1】______conditions. Around a third of Americans and Britons suffer from it. It is thus a worthy enemy and【C2】______its cause is a priority. Until now, this has mostly seemed to lie in the kidneys. But Hidefumi Waki and Julian Paton of Bristol University think they have gathered some valuable new【C3】______—by studying the brain.
In a previous experiment Dr Waki and Dr Paton had found that rodents(啮齿动物)with high blood pressure expressed some genes differently in an area of the brain, called the solitary nucleus(核子), which sets the body’s normal blood pressure level. One of these genes was called "junctional adhesion(粘连)molecule-1 " or JAM-1 for short. It is a molecule normally found in the walls of blood【C4】______that attracts clotting and immune cells—in other words, it causes inflammation. So the pair decided to look at JAM-1 in further depth.
They found that in rats with high blood pressure JAM-1 levels were raised not only in the brain but also the kidney, spleen, lungs and skeletal muscle. To find out whether this was the cause or effect of high blood pressure, they then【C5】______the JAM-1 gene into the solitary nucleus of normal rats. After two weeks, these rats suffered from higher blood pressure than rats that had not received the gene.
【C6】______, experts thought that high blood pressure was caused by the kidneys. The idea was that the kidneys failed to【C7】______the blood pressure. This then caused the lungs to make a hormone(荷尔蒙)that increases blood pressure, leading to a chain of events that raised pressure throughout the blood-vessel network. All blood-pressure-lowering drugs work by seeking to put this right. Yet blaming the kidneys cannot be the full【C8】______of what is going on, because only half the sufferers respond to blood-pressure-lowering drugs. Although these findings are【C9】______, they have far-reaching implications.
Variations in the JAM-1 gene and its expression may explain why high blood pressure tends to run in families, although it is also caused by a poor diet. The finding also shows that the brain could increase the activity of the sympathetic nerves, the part of the nervous system involved in stress response. Ultimately, the finding could hasten the development of drugs that would attack hypertension at its source, stopping its deadly【C10】______in their tracks.
A)sturdy I)explanation
B)vessels J)consequences
C)previously K)nasty
D)perseverance L)reproaching
E)nailing M)transferred
F)preliminary N)intelligence
G)sense O)accordingly
H)reconcile [br] 【C5】
选项
答案
M
解析
结合句意:为了查出这是否是高血压的根源,以及高血压的影响,两人把JAM—1______到正常老鼠的孤束核中。备选动词中的transferred“移植”符合句意,故M)为答案。
