　　Two University of Oklahoma scientists are starting research that they hope will someday lead to the development of a vaccine(疫苗)to fight against the HIV Virus, which causes AIDS．

　　The research, to be carried out by Mark Lang, an assistant professor at the OU Health Sciences Center, and microbiologist John West, will examine the basic aspects of the immune system, rather than the complex aspects of the virus．

　　They theorize that if a key function of the body's immune system can be found exactly, it could be the first step toward developing a vaccine．

　　“To develop a new vaccine, we realzed we first have to study and understand the immune system,”Lang said．

　　Lang said their work will focus on researching the basic antibody responses from Natural Killer－like T－cells．A potential vaccine would contain NKT cells and would improve the immune system's antibodies, which fight outside invaders such as HIV by preventing them from entering cells or giving the immune system enough of a boost to kill them．

　　NKT cells, which have been a part of research into cancer and other diseases, have not previously been the focus of HIV research, Lang said．

　　The research will last 18 months, with tests being performed on mice．The Oklahoma Center is giving ＄300,000 toward the research, and if the research proves promising, Lang and West will apply to the National Institutes of Health for more funding．

　　“If we are successful, we will have made an important contribution to the field, but we will still be several steps away from an effective vaccine,”Lang said．

　　Lang said that in a best –case scenario(最好的情况)their research could lead to a vaccine ready for use in about four years．

Are you nervous about climbing because you think it's too dangerous? Do you feel you're not fit enough to climb? Do you know how to start climbing?

Let's consider the idea that climbing is dangerous．Being afraid is natural, but if you use suitable ropes and other climbing equipments you will feel completely safe．Climbers are usually very careful because they know what they are doing is dangerous．Accidents happen, but when they do, they tend to attract a lot of publicity．As a result, people think there are many more accidents than there are in reality．

You cannot expect to start climbing straight away．Climbing is a challenge and challenges take time．It is necessary first of all that you achieve a good level of fitness．Begin as soon as you become interested in climbing ?go to the gym, go swimming, take up jogging and continue to do so throughout your training period．

Discover as much as you can about climbing．Visit the library and find book, especially for beginners or buy climbing magazines and look for articles which describe your situation．Look up information on the Internet．Find out about equipment, methods and places to go．

Next, take a course on a climbing wall．There are plenty of climbing walls all over the country which have trained and qualified people as instructors．Call your local leisure centre to find out if there is one in your area. These training sessions are a quick way to get experience and you are likely to meet other beginners. After this, you can do an outside course of join a club where you can meet climbers of all abilities and eventually join in group-climbing events.

At first you may not understand the importance of a good training period, but after you have completed your first climb and you are standing safely at the top of a rock feeling thrilled, then you will know it was the right thing to do.
