近十余年来,国外对胸腺素的提纯、生物活性测定、功能的探讨及临床应用进行了广泛深入的研究。认为:胸腺素的作用,不仅对胸腺依赖细胞(Thymus dependentcell简称T—细胞)的发生、成熟及功能起重要作用,而且尚可以通过T—细胞的亚属,如辅助细胞(Helprcelle)、抑制细胞(Suppresser cells)及效应细胞(Effecter cells)等,对产生抗体的B—细胞的活性有一定影响。经动物实验证明,其主要作用于以下三级淋巴细胞:淋巴样干细胞(Lymphoid stem cells)、成熟的淋巴样细胞(Mature lymph-oid cells)以及T—细胞的亚属(Subpopulation of T—cell)。以提纯后的小牛胸
In the past more than ten years, thymosin purification, biological activity measurement, function exploration and clinical application have been extensively studied abroad. It is considered that the role of thymosin plays an important role not only in the occurrence, maturation and function of Thymus dependent cells (T-cells) but also in the subgenus of T-cells such as helper cells and suppressor cells. Suppresser cells and effector cells have a certain influence on the activity of antibody-producing B-cells. Animal experiments have shown that it mainly affects the following three lymphocytes: Lymphoid stem cells, Mature lymph-oid cells, and Subpopulation of T-cells. . After purification calf chest
