涎腺腺样囊性癌过继免疫治疗的实验研究   总被引:1,自引:0,他引:1  
为研究涎腺腺样囊性癌过继免疫治疗的特点,通过体外试验观察了肿瘤坏死因子α(tu-mornecrosisfactorα,TNF-α)与γ干扰素(interferon-γ,IFN-γ)分别作用于白细胞介素2(interleukin-2,IL-2)诱导的淋巴因子激活杀伤(lymphokine-activatedkiler,LAK)细胞杀伤靶细胞不同阶段时对LAK细胞杀伤活性的影响。结果表明腺样囊性癌(adenoidcysticcarcinoma,ACC)-2为LAK杀伤敏感细胞,TNF-α与IFN-γ均适合作为增强剂增强LAK细胞杀伤ACC-2的活性。TNF-α的增强方式是与IL-2共同诱导LAK细胞,而IFN-γ则通过预保温ACC-2细胞提高其被LAK细胞杀伤的敏感性。  相似文献

目的 探讨具有不同转移能力的涎腺腺样囊性癌(adenoid cystic carcinom a; A C C)细胞系中粘附分子表达的差异。方法 采用免疫组化方法对两株人腺样囊性癌细胞系( A C C2 和 A C C M)培养细胞及其 S C I D 小鼠移植瘤模型进行粘附分子 C D44s(标准型)、 C D44v6(变异型)、 Ecadherin( Ecad)、αcatenin(αcat)、βcatenin(βcat)的检测。结果 (1) A C C肺转移灶的肿瘤细胞中粘附分子的表达普遍高于其皮下移植瘤细胞;(2) A C C M 肺转移灶肿瘤生长缓慢,细胞分化相对较好,而其皮下移植瘤和腹腔种植瘤肿块生长迅速,细胞分化差;(3) C D44v6 在 A C C M 和 A C C2 体外培养细胞中均有弱阳性表达,而在异体移植瘤中包括皮下移植瘤和肺部转移灶均无表达。结论  A C C细胞中 C D44s 的表达受细胞分化程度影响,并影响了肿瘤细胞本身的生长状况; Ecad/cat复合体的表达与否或表达强度与肿瘤细胞的分化成正比; C D44v6 在涎腺 A C C中的表达和转移能力可能无关。  相似文献

腺样囊性癌在纤维连接蛋白中趋化功能变化及其浸润机制   总被引:3,自引:1,他引:2  
目的 通过腺样囊性癌(adenoid cystic carcinoma,ACC)在纤维连接蛋白(fibronectin,FN)中的固相趋化功能变化探讨其浸润机制。方法 用Boyden小室法和流式细胞术等测定了3种ACC细胞对FN的趋化反应和细胞表面的受体变化。结果 3种ACC均比鳞状细胞癌(squamous cell carcinoma,SCC)趋化功能强;ACC和SCC细胞表面α2、α3、α6和β1受体亚单位水平高,且ACC3α5也高;受体阻断可见:FN中阻断ACC的α5、β1受体亚单位趋化功能呈高度抑制,阻断α4呈中度抑制,SCC则阻断α1、α4和β1呈强抑制。结论 FN中ACC比SCC侵袭力强;各种细胞不同受体在FN中趋化反应的作用有一定规律。  相似文献

STATEMENT OF THE PROBLEM: Although immediate loading of implants in the edentulous mandible has been described in the literature, there is limited information regarding immediate loading of single implants. PURPOSE: This prospective clinical study evaluated the clinical parameters of immediately loaded single-threaded hydroxyapatite-coated (HA) root form implants. MATERIAL AND METHODS: Ten human subjects were included in this report. In all situations, a screw-retained provisional acrylic resin crown was placed in the maxillary premolar area immediately after implant surgery. Definitive screw-retained metal-ceramic prostheses were placed 6 months after surgery. Standardized periapical radiographs were made before implant surgery, immediately after surgery, and 1, 3, 6, 12, and 36 months after implant surgery. Mobility (measured with the Perio-Test), distance from implant platform to the gingival crevice, distance from the implant platform to the depth of the sulcus, peri-implant probing depth, and bleeding on probing index were recorded at 3, 6, 12, and 36 months after implant placement. For clinical measurements, a 5-mm healing abutment was placed. RESULTS: All implants appeared clinically osseointegrated. Standardized radiographs demonstrated mean marginal bone loss of 0.6, 0.7, 0.8, 0.9, and 1.0 mm at 1, 3, 6, 12, and 36 months after implant surgery, respectively. Mean implant mobility was -3.3 at the day of surgery and -3.8, -3.4, -3.6, and -4.2 at 3, 6, 12, and 36 months, respectively. The distance from implant platform to the gingival crevice was 2.8, 2.4, 2.4, and 3.1 mm at 3, 6, 12, and 36 months, respectively. The distance from the implant platform to the depth of the sulcus was 0.8, 0.9, 0.9, and 1.1 mm at 3, 6, 12, and 36 months, respectively. The peri-implant probing depth was 3.6, 3.3, 3.2, and 4.3 mm at 3, 6, 12, and 36 months, respectively. The bleeding on probing index was 0.4, 0.4, 0.4, and 0.1 at 3, 6, 12, and 36 months, respectively. CONCLUSION: The results of this prospective pilot study provide initial evidence that single root form implants may be immediately loaded when placed at the maxillary premolar area.  相似文献
