老年病的发生,属虚证者多。由于胸腺退化,胸腺素分泌减少,是老年人免疫功能下降的重要原因。而胸腺是T细胞分化、成熟与细胞免疫的中心器官。近年来用从猪与小牛提取的胸腺素进行了一些实验研究与临床观察,所报告的材料说明,胸腺素对于改善细胞免疫功能与免疫调节具有明显的作用。为探索胸腺素对虚证老人的免疫功能的影响,我们观察了35名虚证老人经胸腺素注 The incidence of geriatric illness is more than deficiency. As the thymus degenerates, the decrease of thymosin secretion is an important reason for the decline of immune function in the elderly. Thymus is the central organ of T cell differentiation, maturation and cellular immunity. In recent years, some experimental studies and clinical observations have been conducted using thymosins extracted from pigs and calves. The reported materials indicate that thymosin has an obvious effect on improving cellular immune function and immune regulation. In order to explore the effect of thymosin on the immune function of elderly people with deficiency syndrome, we observed 35 patients with deficiency syndrome who were treated with thymosin.
