RESULTS:After pinealectomized mice was irradiated WBI with 75 mGy X-rays,we found levels of plasma corticosterone increased obviously,and the effects of the proliferative reaction of splenocytes to ConA and spontaneous proliferation of thymocytes was found to be decrease. But injecting melatonin into pinealectomized mice or putting melatonin in the cultured cell,its immune functions might renew the enhancement.CONCLUSION:Melatonin of pineal gland might regulate the immunoenhancement induced by low dose radiation.MeSH Pineal body; Melatonin; Radiation; Corticosterone; Immunity,cellular

低剂量辐射(low dose radiation，LDR)全身照射(whole body irradiation，WBI)可引起免疫系统的兴奋效应，主要表现在以T淋巴细胞功能激活为主的细胞免疫和体液免疫功能的增强并可提高机体的抗瘤作用［4，5］，在LDR诱发免疫功能增强的同时伴有下丘脑-垂体-肾上腺皮质系统功能下调等神经内分泌功能的改变，神经内分泌对免疫系统的调节可能是LDR免疫兴奋效应发生的必要条件，松果腺MLT与辐射免疫兴奋效应的关系值得研究。
