Heating the blood of AIDS patients has been tried before, say doctors. But during previous attempts, the treatment induced deadly chemical changes in the blood. The Biologic-HT System prevents those changes from happening, allowing the heat to kill viruses with few ill side effects. The new heat treatment cannot be considered a cure for Aids, says president of the company that makes the system. He says the treatment doesn’t kill all traces of the virus. However, it kills enough virus particles to give a patient’s immune system a reprieve (终止;暂缓)in its deadly duel with HIV. Tests of the Biologic-HT treatment began on 36 patients earlier this year. The treatment takes about four hours, and the patient normally feels well enough to leave the hospital or clinic the following morning. So far, the patients who have had the treatment say they feel better and have developed no new opportunistic infections(感染)—disease that strike people with damaged immune systems. The patients also have experienced about a 50 percent increase in the number of T cells in their bodies. T cells are key disease-fighting cells of the immune system and the main target of HIV. 67.

Any one who brought his sleeping bag and cooking equipment along could stay there for a very small quantity of money. The idea was a success. A few years later, the school house was much too small to hold the many young people who wanted to stay there. 73 This was the first hostel. (青年招待所) . Today, young sludents and workers of every country can meet in the hostel and get to know each other. When young people arrive at the hostel, they have only to show their cards of membership in a hostel organization in their own country. 74 Often, at the evening meal, a group of boys and girls from various parts of the country or world will happen to meet at the same hostel.
