11、N is a prescription (处方) medicine to help people quit smoking. Studies have shown that more than one third of people quit smoking for at least one month while taking ZYBAN. For many patients, ZYBAN reduces withdrawal symptoms (脱瘾过程中产生的症状) and the strong wish to smoke. 2 ZYBAN should be taken as dire
12、cted by your doctor. The usual recommended dosing(剂量) is to take one 150-mg tablet in the morning for the first 3 days. On the fourth day, begin taking one 150-mg tablet in the morning and one 150-mg tablet in the early evening. Doses should be taken at least 8 hours apart. 3. For most patients, tre
13、atment will last 7 to 12 weeks. Because results vary, it may take longer for some people, Possibly up to 6 months depending on the individual. If you've been smoking for a long time, ZYBAN will help to reduce withdrawal symptoms. It's important to remain on ZYBAN for at least 7 to 12 weeks i
14、n order to quit for good. Your doctor should determine when to stop taking ZYBAN 4. It takes about 1 week for ZYBAN to reach the right levels in your body to be effective So, to increase your chance of quitting as much as possible, you should not stop smoking until you have been taking ZYBAN for 1 w
15、eek. You should set a date to stop smoking during the second week you're taking ZYBAN. 5. The side effects (副作用) associated with ZYBAN are generally mild and often disappear after a few weeks. The most common side effects are dry mouth and difficulty in sleeping. If you have difficulty sleeping,

For example, certain foods can block the chemicals that initate cancer. Antioxidants(抗氧化剂), found in some vitamins and minerals, can snuff out oxygen f

And some foodwheat bran(麦,糠) in particularhas been shown to shrink precancerous(癌症前期的) cells.A recent review of 17 studies from 17 nation
19、s reveals that people who eat the most fruits and vegetables have about half the cancer raters of those who eat the least. In fact, some research suggests that frequent consumption of fruits and vegetables can cut the risk of lung cancer even in smokers.One of the most studied antioxidants in vegeta
20、bles and fruits thought to protect against cancer is beta-carotene(β胡萝卜素), concentrated in deep green, yellow and orange vegetables such as carrots, sweet potatoes and spinach.Research also shows that beta-carotene can change in the body to retinoic acid (维生素A酸), a substance used in clinical tr
21、ials to treat certain cancers.Here are some of the foods that contain cancer-fighting chemicals.Tomatoes. One of the compounds in tomatoes that is thought to reduce the risk of cancer is lycopene(蕃茄素), the pigment (色素) that makes tomatoes red. Lycopene, an antioxidant that is also found in watermelo

A study at Pennsylvania State University found that feeding rats various garlic extracts and preparations(配制好的食物) reduced mammar

In humans, studies suggest that those who eat more onions and garlic are less prone to gastrointestinal cancer.Research suggests that garlic compounds may even interfere with cancer progression. A recent German study found that ajoene, a garlic compound, is toxic t

28、ease. But scientific progress, especially the art of interfering with(干涉,阻碍) the genetic makeup of the human body, has helped doctors prevent more and more inherited disorders in the last decade.Dr. Thomas Caskey of the Baylor University College of medicine in Houston, Texas, is a pioneer in molecul
29、ar biology(分子生物学). Through the techniques of genetic engineering(基因工程), he transfers genes from one organism to another. Caskey uses a certain type of virus, called a retrovirus(逆转录病毒), as the vehicle for the gene transfer. He first cripples the virus by removing the portion it needs to reproduce it
30、self. The crippled virus becomes harmless while still being able to deliver a cargo to its destination.The cargo in Caskey’s experiment is the human A-D-A gene, taken from bone marrow. A-D-A stands for(代表) adenosine deaminase(腺苷脱氨酶), an important component of the human immune system. A defect
31、in the A-D-A gene leads to immune deficiency, rendering(致使) the body defenseless against infections. Caskey’s purpose was to see if the human A-D-A gene could repair the defective immune system of a mouse.In the experiment the mouse was given a dose of radiation heavy enough to destroy its imm
32、une system. The animal next was injected with the crippled virus carrying the human A-D-A gene. According to Caskey, the mouse will die within 10 to 14 days unless a successful transfer of bone marrow cells takes place. So we lethally irradiate and subsequently rescue the mouse by bone marrow transp
33、lantation(骨髓移植)with the cells that have been infected with the virus. The mouse now carries the human gene that salvaged its immune system.Bone marrow transplantation has an established place in contemporary medical practice. Employed to restore the immune system of certain cancer patients and of pe
34、ople who have been exposed to radiation, bone marrow transplantation works only if there is a good match between donor and recipient.The procedure would be much easier if bone marrow were like blood. People with type O blood are universal donors(万能供体). Their blood may be transfused to those who have
35、 different blood types. Unfortunately, there is no such thing as a universal bone-marrow type. Researchers may have found a way, however, to overcome this problem. The solution, if it works, would be to implant the patient with his own, perfectly matching(型配), bone marrow.The idea, as Caskey explain
36、s it, is to correct the patient’s disease with his own ceils, but those cells have added to them a normally functioning gene. In other words, surgeons would take defective bone-marrow cells from the patient and put them into a laboratory dish where the cells would be exposed to a crippled viru
37、s carrying a healthy AD-A gene from a donor. The A-D-A gene would repair the defective cells and then the cells would be reinjected into the patient. Thus, in Caskey words, the patient would be transplanted by his own ceils containing the added normal gene.The technique sounds deceptively(靠不住地) simp
38、le. In reality, though(可是,不过, 然而), it is complex. A number of laboratories have tested various intermediate steps of the process, but, according to Caskey, no single laboratory has put together the entire technology successfully, and highly reproducibly, to proceed with a gene transfer at-tempt in m
39、an.For some time now, the U.S. National Institute of Health has been taking a close look at(仔细,研究) the effectiveness and safety of the procedure, as well as the ethical questions it raises. There doesn’t seem to be much concern about the ethics of gene transfer into a human being to correct a
40、genetic defect.Dr. W. French Anderson of N. I. H. wrote recently that claims that new organs, designed personalities, master races, or Frankenstein(佛兰肯思泰因，一个创造怪物而自己被它毁灭的医学研究者，英国女作家Mary W.Shelly同名小说中的主角) monsters will be created can be given no credence in the light of(根据,从来看) what is presently known

44、k I’d be content. The trouble is that, like most people, I compare my prosperity with that of living persons: neighbors, high-school classmates, TV personalities. The covetousness I feel toward my friend Howard’s kitchen is not mitigated by the fact that no French monarch ever had a refr

46、 achieve happiness would be to realize that even by contemporary standards the things I own are pretty nice. My house is smaller than the houses of many investment bankers’, but even so it has a lot more rooms than my wife’s and I can keep clean. Besides, to people looking back at our er
