The immunoregulation activity of SPG-1 mainly existed in the part of sugar chain, but keeping its molecular structure intact had some effects on its immunoregulation activity; SPG sulphation had reducing effects on the immunoregulation of SPG-1, whereas, after medium and low acetification of SPG, the immunoregulation of SPG was enhanced. Conversely after high acetification, the immunoregulation of SPG-1 decreased, that is, after introducing sulfuric and acetic acid base in SPG-1, its immunoregulation changed. All of these indicated the structure of SPG-1 was closely connected with its immune activity.⑤.

甘薯糖蛋白SPG-1的免疫调节活性主要在其糖链部分，但保持分子结构的完整性对其免疫调节的活性有一定的作用；甘薯糖蛋白硫酸化对甘薯糖蛋白SPG-1的免疫调节有降低作用，而中、低度乙酰化后，可提高甘薯糖蛋白的免疫调节作用，高度乙酰化后则降低其免疫调节作用，即甘薯糖蛋白引入乙酰基和硫酸基团后，其免疫调节活性发生了改变，这些均表明了甘薯糖蛋白的结构与其免疫调节活性有密切的关系。

The reason is the tumor cells escape the immunosurveillance whose mechanism is very complex. In general, the explanation is based on two aspects, one is that the tumor cells can passively escape the host immunosurveillance when the host immnue state is low and another is tumor cells can actively secrete factors to down-regulate immune function.

肿瘤逃避免疫监视的机制非常复杂，但总体上可从宿主免疫状态及肿瘤细胞等方面来解释，在宿主免疫状态低下时，肿瘤细胞可以被动地逃避免疫监视，但是肿瘤细胞也能主动地释放一些活性物质，下调免疫杀瘤作用，该作用主要通过两个途径，即对免疫细胞功能的调节和免疫细胞数量的调节。

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。

As an immunomodulator NO may play a role like a double-edged sword since it expresses both in immuonchalleged and immunosspresed states. 2. After received external stimulus the morphology of ependyma of SFO could be changed and varied with time course, particularly its cellular apoptosis do occur and earlier than the ordinary areas of the brain. 3. Astrocytes in SFO could express cFos protein induced by LPS, suggesting the cells may maintain homeostasis in the brain in a longer period and modulate immune state of the brain. 4. As a CVO, SFO may sense changes of blood-bearing immunosignals earlier and instantly response to them, thus as one of windows of the brain SFO do take part in immunomodulation within the brain.

通过我们的实验结果我们可以得出这样一些初步的结论：1、一氧化氮作为免疫调质参与了机体免疫，它既能在免疫激发状态下又可在免疫抑制状态下进行表达提示，NO在脑内免疫调节中的作用可能是双向的。2、穹窿下器的室管膜形态在接受外界刺激后，随着时间的变化而不同，扫描电镜下的凋亡形态虽需进一步证实，但室管膜细胞确实发生了凋亡，并且穹窿下器发生的较早。3、穹窿下器内的星形胶质细胞在给予大肠杆菌后确实可以表达c-fos蛋白，并可能通过自身的激活来较长时间的维持体液的动态平衡，调节脑内免疫状态。4、穹窿下器作为感受性室周器官之一，能够较早的感受血携免疫信息的改变并及时作出反应，可能作为外周免疫信息进入脑内的窗口之一来参与脑的免疫调节。
