本文介绍了一种简便易行的体外胸腺素生物活性测定方法——E-玫瑰花环形成试验,并初步小结了在恶性肿瘤、自身免疫性疫病、病毒感染以及正常健康成人中的测试情况:1.胸腺素浓度与花环形成率之间呈现剂量相关的关系。2.在一些原发或继发的细胞免疫缺损患者中,胸腺素可使患者的花环形成率恢复或接近正常。3.在一般情况下,正常人或自然花环形成率正常者,其淋巴细胞在体外与胸腺素共同温育后,花环形成率并无明显增高。 This article describes a simple and easy method for measuring the biological activity of thymosin in vitro - the test for the formation of an E-rosette. It also summarizes the tests in malignant tumors, autoimmune diseases, viral infections and normal healthy adults: 1 There was a dose - dependent relationship between thymosin concentration and rosette formation rate. 2. In some primary or secondary patients with cellular immune deficiency, thymosin can make the patient’s rate of rosette recovery or near normal. 3. In normal circumstances, the normal rate of normal or natural rosette formation, the lymphocytes in vitro incubated with thymosin, rosette formation rate was not significantly increased.
