Objective To investigate the changes of melatonin and cellular immunological function in children with febrile seizures and its clinical significance. Methods 50 children, including 23 cases with complex febrile seizure (CFS) and 27 cases with simple febrile seizure (SFS) , and 25 cases with upper respiratory infections children selected as control group were enrolled in this study. Serum melato- nin was measured by enzyme-linked immunosorbent assay (ELISA) and cellular immunological function was measured by flow eytomcter. Results The levels of serum melatonin in the 3 groups of CFS, SFS, control were(14. 91±2. 61) ng/L, (20. 72±2. 54) ng/L, (23.93± 2. Ol) ng/L, respectively. The melatonin levels in CFS children were significantly decreased than that in control group and SFS children (P <0. O1). CD3 + ,CD4 +, the ratio of CD4 + /CD8 + and CD8 + in CFS group were significantly decreased than that in control group and SFS group (P <0.01). The ratio of CD4 +/CD8 + in SFS group was significantly decreased than that in control group (P <0.05), but CD3 + ,CD4 + and CD8 + had no statistics significance among these groups(P >0. 05). The serum rnelatonin level were positive related withdecreaseddegreeofCD3+,CD4+ andtberatioofCD4+ /CDS+ (r≥0. 472, P <0.05). Conclusion The disorder cfcellular immunological function was possible related with the loss of serum melatonin, and the loss of serum melatonin maybe one of the reasons for febrile seizures relapse and brain injured. 相似文献

用RT-PCR半定量分析结果显示,Graves病甲状腺组织及甲状腺腺瘤瘤旁正常甲状腺组织(各5例)均存在褪黑素受体亚型mt1mRNA的表达,未检测到MT2亚型。手术时经药物控制甲状腺功能已正常的Graves病与甲状腺机能仍亢进的Graves病甲状腺组织mt1表达量无差异(P>0.05);Graves病甲状腺组织mt1表达量较正常甲状腺组织明显增加(P<0.01)。提示褪黑素的免疫调节作用可能通过mt1介导,Graves病发病可能与mt1亚型激活有关。 相似文献

褪黑激素抗氧化作用的研究进展 总被引:3,自引:0,他引:3
褪黑激素是松果体分泌的一类激素,对其研究起初主要集中在调节睡眠的作用,但近年发现其具有强大的抗氧化应激作用。实验研究表明,褪黑激素不仅本身具有明显的抗氧化作用,且被氧化后的多级代谢产物亦有强大的抗氧化功能;还具有同时清除氧族和氮族自由基的双重功效及上调多种抗氧化酶活性的功能。目前对于它在缺血再灌注损伤、抗癌、抗退行性变等领域的应用研究取得众多进展。本文主要综述近年来褪黑激素抗氧化机制及其应用的研究进展。 相似文献
