负离子常用来清新空气,在充满负离子的房间生活会让人感到心情愉快。日本富山医药大学田泽贤次教授等人最近发现,负离子还可以增加人体内的抗氧化物,降低活性氧对人体的伤害。 人体内过量的活性氧会对细胞蛋白质造成伤害,从而诱发癌症。因此,如何减少人体内的活性氧一直是专家关注的课题。田泽教授等人为此做了这样一个实验:在一个房间内安装负离子发生装置,离装置3米以内的区域每平方厘米负离数可达到约2.7万个,是另一个不安装
Negative ions are often used to refresh the air. Living in a room filled with negative ions will make people feel happy. Professor Toshihisa Tazawa from Japan’s Toyama University of Medicine and others recently discovered that negative ions can also increase antioxidants in the body and reduce the harmful effects of reactive oxygen species on the human body. Excessive amounts of reactive oxygen species in the human body can cause damage to cellular proteins and thereby induce cancer. Therefore, how to reduce the amount of active oxygen in the human body has always been an issue of concern to experts. Prof. Tasawa et al. did an experiment for this purpose: In a room equipped with negative ion generators, the number of negative ions per square centimeter within 3 meters from the device can reach about 27,000, which is not the other
