A medicine approved last month to treat AＩDS (爱滋病) also shows promise against hepatitis B (乙型肝炎).
The drug, 3TC, puts down the hepatitis B virus in people with chronic infections, stopping its damage to the liver, researchers reported.
About one million Americans are thought to be infected with hepatitis B, which can lead to cirrhosis (肝硬化), liver failure and liver cancer in a small proportion of victims if left untreated.＿＿＿＿＿＿＿(46)
"It's a preliminary study, but this is promising, it looks like it has the potential to make a significant impact on hepatitis B," said Dr Jules L. Dienstag of Massachusetts General Hospital, who directed the study.
Currently, the only treatment for hepatitis B is interferon (干扰素). Such a treatment can permanently eliminate the virus in about one-third of patients. ＿＿＿＿＿＿(47)
In the latest study, doctors found that 3TC appeared to knock out the virus
permanently in about 20% of patients when given for three months.＿＿＿＿(48)
Unlike interferon, 3TC is given in pill form. and carries few side effects. The drug was approved by the Food and Drug Administration in November for use against AIDS.
Both the hepatitis B virus and the AIDS virus need a protein to reproduce.
＿＿＿＿＿(49) Doctors have tested similar AIDS drugs against hepatitis B． But all except 3TC have turned out to be ineffective or too toxic (有毒的).
Dr Jay Hoofnagle of the National Institutes of Health said a next step will be to combine 3TC with interferon to see if the two drugs together improve the chance of curing hepatitis B． "It looks extremely promising," he said of 3TC． ＿＿＿＿＿(50)
A． 3TC is One of a group of drugs that block production of this protein.
B．Interferon must be injected for four to six months and often has unpleasant side effects, including flu-like symptoms, fatigue and depression.
C． The hospital is among the biggest ones in America.
D．Dienstag said he hopes that with longer treatment, this response rate can be
doubled.
E． "It's not the answer, but it's a step in the right direction."
F． Perhaps 20% of these patients have lingering (迁延性的) infections that would benefit from treatment.
第 46 题 请选择（46）处的最佳答案．
The National Education Association claims, “The school bus is a mirror of the community.” They further add that, unfortunately, what appears on the exterior does not always reflect the reality of a chosen community. They are right -- sometimes it reflects more! Just ask Liesl Denson. Riding the school bus has been more than a ride to school for Liesl.
Bruce Hardy, school bus driver for Althouse Bus Company has been Liesl's bus
driver since kindergarten. Last year when Liesl's family moved to Parkesburg, knowing her bus went by her new residence, she requested to ride the same bus.
This year Liesl is a senior and will enjoy her last year riding the bus. She says, "it's been a great ride so far! My bus driver is so cool and has always been a good friend and a good listener. Sometimes when you're a child adults do not think that what you have to say is important. Mr. Hardy always listens to what you have to say and makes you feel important." Her friends Ashley Batista and Amanda Wolfe agree.
Bruce Hardy has been making Octorara students feel special since 1975. This year he will celebrate 30 years working for Althouse Bus Company. Larry Althouse, president of the company, acknowledges Bruce Hardy's outstanding record: "You do not come by employees like Bruce these days. He has never missed a day of work and has a perfect driving record. He was recognized in 2000 by the Pennsylvania School Bus Association for driving 350,000 accident free miles. Hardy's reputation is made further evident through the relationships he has made with the students that ride his bus."
Althouse further adds, "Althouse Bus Company was established 70 years ago and has been providing quality transportation ever since. My grandfather started the business with one bus. Althouse Bus Company is delighted to have the opportunity to bring distinctive and safe service to our local school and community and looks forward to continuing to provide quality service for many more years to come."
Three generations of business is not all the company has enjoyed. Thanks to drivers like Bruce Hardy, they have been building relationships through generations. Liesl's mother Carol also enjoys fond memories of riding Bruce Hardy's bus to the Octorara School District.
