The potential value of interleukin 1 (IL-1) containing supernatants as a radioprotective agent was evaluated. It was found that the response of irradiated thymocytes to mitogens was partially restored if IL-1 containing supernatants was included in the culture medium immediately after irradiation. A delay of 24 h in the addition of IL-1 and mitogen abrogated the radioprotection effect. Under the same conditions IL-2 containing supernatants were effective, suggesting that the dose modifying effect of IL-1 acts through induction of IL-2 elaboration. The results of the present study may be important in cases where it is necessary to restore depressed immune response resulting from irradiation accidents or radiotherapy.
评估了含白细胞介素1(IL-1)的上清液作为辐射防护剂的潜在价值。研究发现,如果在照射后立即将含IL-1的上清液加入培养基中,受照射胸腺细胞对有丝分裂原的反应可部分恢复。添加IL-1和有丝分裂原延迟24小时会消除辐射防护效果。在相同条件下,含IL-2的上清液也有效,这表明IL-1的剂量调节作用是通过诱导IL-2的分泌来实现的。本研究结果对于因辐射事故或放射治疗导致免疫反应抑制而需要恢复的情况可能具有重要意义。
