人们常说的机体免疫力,以往仅仅是指机体抵抗病原微生物的能力,所以又俗称“抗病能力”。随着医学科学的发展,人们发现免疫是机体在识别自己的基础上,识别、消灭和排除抗原性异物以维护机体的稳定和生理平衡的过程。但是,它对机体的作用是双重性的。现代医学研究证实,免疫不仅仅是机体的“朋友”,有时,它还是“潜伏”在体内的“敌人”。 People often say that the body’s immunity, in the past just refers to the body’s ability to resist pathogenic microorganisms, it is also commonly known as “disease-resistant ability.” With the development of medical science, people find that immunity is the process of recognizing, eliminating and eliminating antigenic foreign bodies so as to maintain the stability and physiological balance of the body on the basis of recognizing itself. However, its effect on the body is twofold. Modern medical research confirms that immunity is not just the “friend” of the body, but it is also sometimes “hidden” in the body.
