早在本世纪60年代,人们已经认识到自由基与疾病存在某种关系,但因自由基的生物半衰期甚短,当时受到技术方面的限制,研究进展甚慢。近年来,由于分子生物学的迅速发展,在研究技术方面也有了新的突破,推动了自由基生物学的发展。现已发现自由基与人类的衰老、肿瘤、心血管疾病等都有密切关系。目前已形成了一个蓬勃发展的新兴的自由基生物医学领域。一、自由基与自由基损伤:自由基是指具有不配对电子的分子、离子或基团;当化
As early as the 1960s, people had realized that there was a relationship between free radicals and diseases, but due to the short biological half-life of free radicals, they were technically limited at the time and research progress was slow. In recent years, due to the rapid development of molecular biology, new breakthroughs have also been made in research technology, which has promoted the development of free radical biology. It has been found that free radicals are closely related to human aging, cancer, and cardiovascular diseases. A flourishing emerging free radical biomedical field has now formed. 1. Free radicals and free radical damage: Free radicals are molecules, ions, or groups that have unpaired electrons;
