The further study showed that flumazenil, the benzodiazepine antagonist, and picrotoxin, the ligand of picrotoxin site on GABA〓 receptor, significantly antagonized hypnotic activity of melatonin by using EEG analysis in rats.

当机体昼夜节律系统功能正常时，在六个昼夜不同时间点给予12小时光照／12小时黑暗下生活的小鼠褪黑素后，延长小鼠睡眠时间的峰值出现在光照期开始，谷值出现在光照末期。

The concentration of electrolytes in the serum of pika does not be affected by environmental conditions that pika lives.

Hill of the 2 oxide silicon components of the Airframe, Engine damage, pilot sight, it is very dangerous, affected European countries have been forced to take the "9. 11 "incident has been the largest grounded.

火山灰里的二氧化硅等成分会对飞机机体、发动机造成损害，影响飞行员视线，非常危险，受影响的欧洲各国因此被迫采取了"9.11"事件以来最大规模的停飞措施。

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。
