A.多黏菌素E

B.头孢哌酮

C.氨苄西林

D.庆大霉素

E.克林霉素

答案

参考答案:B

解析:对铜绿假单胞菌感染作用较强的抗菌药物有半合成青霉素,如阿洛西林和哌拉西林,其中以哌拉西林为最常用;第三代头孢菌素中以头孢他啶、头孢哌酮的作用较强;其他还有β-内酰胺类药物中的亚胺培南及氨曲南;氨基糖苷类中的庆大霉素、妥布霉素、阿米卡星和异帕米星;氟喹酮类如氧氟沙星、环丙沙星及氟罗沙星等也有一定作用。题中多黏菌素E、庆大霉素虽然对铜绿假单胞菌感染有效,但有肾毒性,其余二药对铜绿假单胞菌感染无效。

An old problem is getting new attention in the United States—bullying. Recent cases included the tragic case of a 15-year-old girl whose family moved from Ireland. She hanged herself in Massachusetts following months of bullying. Her parents criticized her school for failing to protect her. Officials have brought criminal charges against several teenagers.

Judy Kuczynski is president of an anti-bullying group called Bully Police USA. Her daughter Tina was also the victim of severe bullying starting in middle school in the state of Minnesota. She said,“Our daughter was a very outgoing child. She was involved in all kinds of things and had lots of friends. And over a period of time her grades fell completely. She started having health issues. She couldn't sleep. She wasn't eating. She had terrible stomach pains and didn't want to go to school.”

Bullying is defined as negative behavior repeated over time against the same person. It can involve physical violence, or it can be verbal—for example, insults or threats. Spreading lies about someone or excluding a person from a group is known as social or relational bullying.

And now there is cyber-bullying, which uses the Internet, e-mail or text messages. It has easy appeal for the bully because it does not involve face-to-face contact and it can be done at any time.

The first serious research studies into bullying were done in Norway in the late 1970s. The latest government study in the United States was released last year. It found that about one-third of students age twelve to eighteen were bullied at school.

Susan Swearer is a psychologist at the University of Nebraska-Lincoln and co-director of the Bullying Research Network. She says schools should treat bullying as a mental health problem to get bullies and victims the help they need. She says bullying is connected to depression, anxiety and anti-social behavior and bullies are often victims themselves.
