摘要:

目的:探讨外源性IL-10对炎症牙龈组织中IL-6和细胞间粘附分子-1(ICAM-1)表达的影响。方法:采用免疫组化技术检测牙周袋内用或不用IL-10时成人牙周炎患者牙龈组织中IL-6和ICAM-1的表达。结果:IL-6和ICAM-1 均可在炎症牙龈组织的多种细胞表达。IL-6主要表达于淋巴细胞、单核)巨噬细胞、成纤维细胞和内皮细胞。I- CAM-1主要表达于淋巴细胞、上皮细胞、单核)巨噬细胞、成纤维细胞和内皮细胞。使用Image-Proplus软件系统测得的IL-6和ICAM-1表达的IOD值在实验组和对照组间有显著性差异(P<0105)。结论:外源性IL-10对炎症牙龈组织中IL-6和ICAM-1的表达有下调作用。

Abstract:

Objective:This study aimed at investigating effects of exogenous interleukine-10 (IL-10) on IL-6 and intercellular adhesion molecular (ICAM-1) expression in inflamed gingival tissue.Methods:The expression of IL-6 and ICAM-1 was examined using im- munohistochemical techniques. Inflammatory gingival tissue treated with IL-10 was taken as the experimental group and the same patient.s inflammatory gingival tissue without treatment of IL-10 was included into the control group.Results:IL-6 expression was found mainly in monocytes, macrophages, lymphocytes, endotheliocytes and fibroblasts. The expression of ICAM-1 was found mainly in epithelial cells, monocot-macrophages, lymphocytes, endotheliocytes and fibroblasts. The immunohistochemical optical density (IOD) of the expression of IL-6 and ICAM-1 was detected by using Image-Proplus software, and the results showed thatthe expression in the experimental group differed significantly from that in the control group.Conclusion:The exogenous IL-10 may down-regulate IL-6 and ICAM-1 expression in inflammatory gingival tissue.
