近年来对老年医学的研究日益重视,认为衰老的发生与免疫系统功能的变化有密切关系。由于老年人的免疫功能发生了改变,从而造成机体抗传染免疫力下降,免疫调节机能失衡和免疫监视功能减弱,所以老年人容易发生自身免疫性疾病、肿瘤和感染。因此研究老年人免疫功能状态的变化,是老年医学范畴中的重要课题之一。为此,我们检测39例60岁以上的老年人和27例年轻合格输血员外周血中T细胞及其亚群分布情况和对植物血凝素的反应,作为初步观察衰老与T细胞的数量和功能之间
In recent years, the research of geriatric medicine has been paid more and more attention. It is believed that the occurrence of aging is closely related to the changes of the immune system. As the elderly’s immune function has changed, resulting in decreased immunity to the body’s immune system, immune dysregulation and immunosurveillance function weakened, so the elderly prone to autoimmune diseases, tumors and infections. Therefore, studying the changes of immune function in the elderly is one of the important topics in the field of geriatrics. To this end, we examined the distribution of T cells and their subsets and the response to phytohemagglutinin in peripheral blood of 39 elderly people over the age of 60 and 27 young transfusionrs as a preliminary observation of the number of aging and T cells and Between functions
