目的:观察干细胞因子(stem cell factor,SCF)在慢性根尖周病患者肥大细胞(mast cells,MCs)中的表达情况,探讨SCF阳性MCs在根尖周病发病机制及根尖周纤维组织的形成,尤其在根尖周囊肿纤维组织形成中的作用。方法:选择2011年7月~2013年6月期间在暨南大学荔湾口腔教学医院临床诊断为根尖囊肿或根尖肉芽肿并接受根尖刮治手术的病例30例,其中根尖肉芽肿15例,根尖囊肿15例。正常对照组20例,取自因正畸需要拔除的牙周健康的前磨牙。标本经10%甲醛固定48 h以上。组织标本经石蜡包埋、组织连续切片,HE染色,光学显微镜下观察其组织学改变;采用免疫组织化学法,观察各组标本组织中MCs数目及MCs脱颗粒情况;采用免疫荧光双染色法,在荧光显微镜下观察各组标本组织中tryptase-SCF双阳性MCs数目。结果:免疫组织化学染色结果显示,2组慢性根尖周病组织中MCs和脱颗粒MCs数量与正常对照组相比显著增多( P<0.01);根尖囊肿组的MCs和脱颗粒MCs的数量均明显高于根尖肉芽肿组(P<0.05)。免疫荧光双染色结果显示,2组慢性根尖周病组织中的tryptase-SCF双阳性MCs密度与正常对照组相比显著增多( P<0.01);根尖囊肿组tryptase-SCF双阳性MCs密度明显高于根尖肉芽肿组( P<0.05)。各组标本组织中免疫组织化学染色MCs密度与免疫荧光双染色MCs密度无显著差异(P>0.05)。结论:Tryptase-SCF双阳性肥大细胞在慢性根尖周病的炎症损害,尤其在根尖囊肿的纤维组织形成中发挥重要作用。 Tryptase-SCF双阳性肥大细胞与慢性根尖周病炎症损害的发生、进展及其持续存在有关。
目的:觀察榦細胞因子(stem cell factor,SCF)在慢性根尖週病患者肥大細胞(mast cells,MCs)中的錶達情況,探討SCF暘性MCs在根尖週病髮病機製及根尖週纖維組織的形成,尤其在根尖週囊腫纖維組織形成中的作用。方法:選擇2011年7月~2013年6月期間在暨南大學荔灣口腔教學醫院臨床診斷為根尖囊腫或根尖肉芽腫併接受根尖颳治手術的病例30例,其中根尖肉芽腫15例,根尖囊腫15例。正常對照組20例,取自因正畸需要拔除的牙週健康的前磨牙。標本經10%甲醛固定48 h以上。組織標本經石蠟包埋、組織連續切片,HE染色,光學顯微鏡下觀察其組織學改變;採用免疫組織化學法,觀察各組標本組織中MCs數目及MCs脫顆粒情況;採用免疫熒光雙染色法,在熒光顯微鏡下觀察各組標本組織中tryptase-SCF雙暘性MCs數目。結果:免疫組織化學染色結果顯示,2組慢性根尖週病組織中MCs和脫顆粒MCs數量與正常對照組相比顯著增多( P<0.01);根尖囊腫組的MCs和脫顆粒MCs的數量均明顯高于根尖肉芽腫組(P<0.05)。免疫熒光雙染色結果顯示,2組慢性根尖週病組織中的tryptase-SCF雙暘性MCs密度與正常對照組相比顯著增多( P<0.01);根尖囊腫組tryptase-SCF雙暘性MCs密度明顯高于根尖肉芽腫組( P<0.05)。各組標本組織中免疫組織化學染色MCs密度與免疫熒光雙染色MCs密度無顯著差異(P>0.05)。結論:Tryptase-SCF雙暘性肥大細胞在慢性根尖週病的炎癥損害,尤其在根尖囊腫的纖維組織形成中髮揮重要作用。 Tryptase-SCF雙暘性肥大細胞與慢性根尖週病炎癥損害的髮生、進展及其持續存在有關。

AIM: To investigate the expression of stem cell factor (SCF) in tryptase -positive mast cells ( MCs) in different types of human periapical diseases for determining the role of SCF and MCs in the pathogenesis of peria-pical diseases.METHODS: A total 50 cases of specimens were involved in this study, including healthy control (n=20), periapical cyst (n=15) and periapical granuloma (n=15).The tissue material was fixed in 10%formalin for at least 48 h, stained with hematoxylin and eosin for the observation of histopathology, stained with immunohistochemistry for identifying MCs and MCs degranulation, and stained with double immunofluorescence for identification of tryptase-SCF double positive MCs.RESULTS:Compared with healthy control, significantly higher densities of both total and degranu-lated MCs in human periapical lesions were observed.The densities of both total and degranulated MCs in the periapical cyst were significantly higher than that in the periapical granuloma.The density of tryptase-SCF double positive MCs in the periapical lesions was significantly higher than that in the healthy controls.The density oftryptase-SCF double positive MCs in the periapical cyst was significantly higher than that in periapical granuloma.No significant difference in the density of MCs between immunohistochemistry staining and double immunofluorescence staining was observed.CONCLUSION:The tryptase-SCF double positive MCs play an active role in the pathogenesis of the periapical inflammatory lesions, particularly in the formation of fibrous tissue in periapical cyst.The potential role of the tryptase-SCF double positive MCs relates with the initiation, development, and persistence of the periapical inflammatory process.
