美国达拉斯消息:研究人员发明了一种杀死供者血液中某些病毒的方法,可预防因供血而致艾滋病(AIDS)。研究人员发现,强烈的光照与一种无毒染料联合应用可杀死麻疹和单纯性疤疹等病的致病因子,而不损伤血液本身。由Baylor研究基金会的8个成员组成的研究小组将在2月对血液中的艾滋病病毒进行试验。此项技术于1984年开始进行实验室小规模试验,经过3～5年的改进现已能广泛应用。研究人员认为,目前常用的检查血库供血中AIDS的方法虽然很好,但精确度达不到100％,因为检测的是AIDS抗体而不是艾滋病病毒(HIV)。HIV病毒抗体在2个月后才产生,因
Dallas, United States: Researchers invented a method to kill certain viruses in the blood of donors to prevent AIDS caused by blood supply. The researchers found that a combination of intense light and a non-toxic dye can kill causative agents such as measles and herpes simplex without damaging the blood itself. A team of eight members from the Baylor Research Foundation will test the blood for HIV in February. The technology began in 1984 laboratory small-scale experiments, after 3 to 5 years of improvement is now widely used. Researchers believe that the current commonly used method of blood tests for blood donation in AIDS is good, but the accuracy is less than 100% because AIDS antibodies are tested instead of HIV. HIV virus antibody produced after 2 months, because
