特异性

The device utilizes a lutetium yttrium orthosilicate scintillator crystal, curved photomultipliers, and Philips' proprietary TruFlight technology , which uses the time difference -- in pico seconds (10-12 seconds)-- between the detection of coincident events to more accurately identify the origin of the annihilation.

飞利浦医疗系统PET/CT产品全球市场总监Jim Cavanaugh介绍说，采用Gemini TF进行全身PET扫描用时不到10分钟，此前进行同样的检查需要15分钟或更长时间，对肥胖病人同样如此；如果医生需要获得敏感性或特异性更高的PET图像，获取图像的时间还是维持在原来的水平上，这需要根据病人临床情况而决定。

Methods The microlymphatic density and lymphatic vessel invasion in 102 cases of breast cancer tissue were evaluated by immunohistochemical staining, using monoclonal antibody for podoplanin. The characteristic of microlymphatic vessel and the relationship between MLD, LVI and clinicopathological parameters were evaluated.

采用微淋巴管标记物podo-planin对102例乳腺癌组织进行免疫组化染色，观察微淋巴管的特点，分析乳腺癌中微淋巴管密度及淋巴管浸润与临床病理参数之间的关系，并与血管标记物CD34进行双标免疫组化染色，观察podoplanin标记淋巴管的特异性。

METHODS By using PCR and IK staining techniques, the tubercles were measured in the tissues from 35 cases of tuberculosis, 30 cases of non-specific lymphadenitis and 10 cases of normal fetus.

采用IK染色和PCR技术，对结核病患者（35例）、非特异性淋巴结炎患者（30例）和正常胎儿（10例）的石蜡切片进行对比研究。

Methods: Affinity chromatography was used to purify B16 HACs.γ-IFN and IL-2 secreting activities were determined with crystal voilet staining and lymphoblast proliferation induced by Con A, respectively. Pecific CTL killing rate was detemined with 3H-TdR incorporation.

CNBrSepharose 4B亲和层析法提纯B16HACs，应用体内免疫法检测HAC的抑瘤作用，结晶紫染色法检测γIFN分泌活性，ConA诱导的淋巴母细胞增殖法检测IL2分泌活性，3HTdR掺入法检测特异性CTL的杀伤活性。

Objective To observe specific cytotoxicity induced by dendrtic cells pulsed with bladder tumor lysate towards bladder cancer cell line.
