胸腺是机体主要的免疫器官之一,实验证明未切除胸腺的成年动物虽遭辐射损伤,但在恢复过程中能重建免疫功能。而成年动物若切除胸腺后再造成辐射损伤,则不能重建免疫功能。因此,胸腺在免疫损伤的恢复中有重要作用。近年来的研究发现胸腺的网状上皮细胞可产生胸腺激素,它与免疫功能的建立有密切关系。目前研究较多的胸腺中多肽激素有:促胸腺生成素Ⅰ、Ⅱ(Thymopoietin)、胸腺素(Thymosin)、胸腺体液因子(THF)、血清胸腺因子(STF)等。某些胸腺提取物已在临
The thymus is one of the major immune organs of the body. Experiments have shown that although the adult animals without thymus have been damaged by radiation, they can reconstruct the immune function during the recovery process. The adult animal, if the thymus after resection caused by radiation damage, you can not reconstruct the immune function. Therefore, the thymus plays an important role in the recovery of immune damage. In recent years, studies have found that thymus reticuloendothelial cells can produce thymus hormone, which is closely related to the establishment of immune function. Thymus peptide hormones currently studied more: Thymopoietin, Thymosin, Thymus, Thymus factor (STF) and so on. Some thymus extracts are on the way
