本文应用~3H-TdR 掺入淋巴细胞转化试验,对鼻咽癌患者放射治疗前后的细胞免疫功能进行了动态观察。结果表明,治疗后3个月内细胞免疫功能较治疗前明显降低,以后有所回升,至一年以后接近正常;提示放射治疗对细胞免疫功能有一定的损伤作用,但这种损伤是可逆的。 In this paper, ~ 3H-TdR incorporation into lymphocyte transformation test was used to observe the cellular immune function of patients with nasopharyngeal carcinoma before and after radiotherapy. The results showed that within 3 months after treatment, the cellular immune function was significantly lower than that before treatment and later rose back to normal one year later. It suggested that radiation therapy had a certain damage effect on cellular immunity, but this injury was reversible .
