目前公认胸腺为免疫系统的主宰腺体,控制免疫系统的发育和功能。胸腺素是胸腺分泌的一簇多肽类激素,具有促进T淋巴细胞增生和恢复机体细胞免疫功能的生物活性。日本难波修一曾作为专利报道了“哺乳动物胸腺对白细胞及淋巴细胞减少症有效物质的制法”,并对这种物质进行了抗放提白的实验研究,肯定了有明显延长寿命的效果,能抑制骨髓有核细胞减少,促进其恢复。对小鼠因注射~(32)磷引起的白细胞特别是淋巴细胞减少,有明显的抑制作用。Mazewska Czyzewska M等给瑞士小鼠腹腔注射胸腺素,结果提高了一次~(60)钴照射480伦或550伦小鼠的存活率。胸腺细胞对辐射敏感的事实早已被人们所
Thymus is now recognized as the dominant gland of the immune system and controls the development and function of the immune system. Thymosin is a cluster of polypeptide hormones secreted by the thymus gland and has biological activity that promotes T lymphocyte proliferation and restores cellular immune function. Nippon Nippon Koichi once reported as a patent on the “method for the production of effective substances for leukocytes and lymphopenia by the mammalian thymus gland”, and conducted an experimental study on anti-whitening of this substance, affirming the effect of significantly prolonging lifespan. Can inhibit the reduction of bone marrow nucleated cells and promote their recovery. The inhibition of leukocytes, especially lymphocytes, caused by the injection of ~(32)P has a significant inhibitory effect on mice. Mazewska Czyzewska M et al. gave intraperitoneal injections of thymosin to Swiss mice, which resulted in an increase in the survival rate of 480 or 550 lux mice irradiated with 60 cobalt. The fact that thymocytes are sensitive to radiation has long been
