1997年10月6日,美国加州大学旧金山医学院的普鲁西纳教授获得了100万美元的本年度诺贝尔生理学奖与医学奖。这是因为他在研究朊病毒、揭开“疯牛病”之谜方面,做出了杰出的贡献。 疯牛病(BSE),医学上称之为“牛海绵状脑病”,于1985年4月在英国第一次发现这种病例。该病多发生于4岁左右的成年牛,症状表现为烦躁不安,行为反常,对声音和触摸过分敏感,常因恐惧和狂躁而呈攻击性。少数病畜还有头部和肩部肌肉颤抖和抽搐。
On October 6, 1997, Professor Prussiana at the University of California San Francisco School of Medicine won the $ 1 million Nobel Prize in Physiology and Medicine for this year. This is because he made outstanding contributions to the study of prions and the mystery of “mad cow disease.” BSE, medically referred to as “bovine spongiform encephalopathy,” was first reported in the United Kingdom in April 1985. The disease occurs mostly in 4-year-old adult cattle, the symptoms manifested as irritability, abnormal behavior, excessive sensitivity to sound and touch, often due to fear and mania was aggressive. A small number of sick animals also have head and shoulder muscle tremors and convulsions.
