现在已经知道,胸腺是人体一个重要器官,它能产生胸腺素。国外对胸腺的研究已有150多年历史,1949年Robberts 和White 用小牛胸腺制备了无细胞抽出液,1965年Gold-stein 从小牛胸腺提取了胸腺素(Thymosin)。近十几年来对胸腺素研究进展很快,迄今已有十几个国家对之进行研究,他们抽提的胸腺素均系蛋白质或多肽,但制备方法、有效成份、命名都不尽相同。
It is now known that the thymus is an important organ of the human body and it produces thymosin. Studies of thymus in foreign countries have been more than 150 years old. In 1949, Robberts and White prepared cell-free extracts from the calf’s thymus. In 1965, Gold-stein extracted thymosin (Thymosin) from calf’s thymus. Research on thymosins has progressed rapidly in the past decade or so and has been studied in more than a dozen countries so far. The thymosins extracted by them are all proteins or polypeptides, but their preparation methods, effective ingredients, and names are all the same.
