  negative images
Within this panorama of history certain immediate overtly negative images of the other can be perceived in both traditions, manifested in terms of actions and literature.
      
The white matter fiber tracts appear essentially as "negative images".
      
Participants (n?=?13) were presented emotionally positive or negative images under different anticipatory conditions, and their subsequent brain responses were recorded by magnetoencephalography (MEG).
      
The decreased solubility and lower vapor pressure of the phototransformed material enables wet (organic solvents) or dry (thermal or photon-induced sublimation) development of photo-defined negative images.
      
The objective functions include: (O-1) precision; (O-2) average rank; (O-3) ratio of within-class (i.e., positive images) and between-class (i.e., positive and negative images) scatter; and (O-4) combination of O-2 and O-3.

A radiolabeled monoclonal antibody (McAb) 6c6 was used to detect the metastatic lymph nodes of breast cancer externally and internally. In-111 was labeled to 6c6 by DTPA method. Iodogen method was used to label I-131. Hosted tumor in nude mouse model could be demonstrated by both isotopes labeled 6c6 with external gamma imaging. The radiolabeled 6c6 was injected into the web space of esch in seven women with breast cancer and one with benign breast tumor. The scans were positive in two axillae with palpable nodes and four with impalpable nodes. Pathologic examination later confirmed metastases in five of the axillae. Two axillae, one of which with palpable nodes, showed negative result, and here no tumor cells were found by pathologists. Intraoperative metastatic lymph node detection with a hand-held gamma probe was carried out in six patients. 24 lymph nodes were measured with 17%(1/6) false negative and no false positive result (0/18), indicating that the result detected by the hand-held gamma probe presents the real radioactivity of the tissues examined. There were 60 lymph nodes that were removed and detected again by well shape detector after operation. The false positive rate was 14%(6/42), and the false negative rate was 11%(2/18), indicating that the radiolabeled McAb 6c6 could spe- cifically combine with the metastatic lymph nodes of breast cancer in vivo.

本文报告用抗乳癌单克隆抗体6C6对乳癌转移淋巴结进行体外和体内放射免疫定位的研究。用DTPA法标记~(111)铟,Iodogen法标记~(131)碘。经双侧指蹼注药对7例乳癌和1例良性乳腺肿瘤患者进行腋窝淋巴结的体外放射免疫显像。6例患侧腋窝显阳性影像,病理诊断证实其中5例有淋巴结的转移:2例显像阴性,病理结果均未见癌细胞转移。用小型季持式γ探测仪对6例患者的腋窝淋巴结进行了术中放射免疫探测。24个淋巴结的探测结果,假阳性率0/18,假阴性率1/6。对术后解剖出的60个淋巴结用井型γ幂测仪进行探测,假阳性率6/42,假阴性率2/18。

Eleven patients with breast cancer and 2 normal individuals were studied by radionuclide biological targeting technique with 131Ⅰ labelled monoclonal antibody C50. The imaging was recognized as Positive in 8 Patients and negative in 3 patients.In 7 of the eight positive patients the lymph nodes were proven pathologically to harbor metastatic foci and the eighth was found to contain CEA-antigen and antigen-antibody immunocomplexes in the lymphoid sinus by immunohistochemistry. No cancer cell was found histologically in the axillary lymph nodes of 3negative imaging gatients. As to the 2 normal controls imaging was negative.The results of this study not only demonstrated that the radionuclide biological targeting technique was useful in the diagnosis and localization of axillary lymph node metastases from breast cancer,but also indicated great clinical significance in surgery.

应用 ̄(131)Ⅰ标记的单克隆抗体C_(50)对11例乳腺癌患者及2例正常人进行放射性核素生物导向诊断,结果8例呈阳性显像,其中7例术后经病理证实,另1例术后切下的7个淋巴结常规病理检查未找到癌细胞,免疫组化证实淋巴窦腔内存在癌胚抗原及抗原-抗体免疫复合物。3例显像阴性者术后病理检查未找到癌细胞。2例正常对照者(4侧腋窝)均阴性显像。木研究证明:该方法诊断乳腺癌腋窝淋巴结转移灶可以准确定性、定位,对指导临床手术有一定价值。

目的:探索肠癌及其转移灶的诊断方法。方法:使用高汝桢改良的Schwarz方法进行99mTc标记抗CEA单克隆抗体(C50),对临床疑肠癌患者22例、肠癌术后患者5例静脉注射标记抗体后6小时和(或)24小时进行放射免疫显像(RII),并与手术和病理结果进行对照。结果:24例肠恶性病变手术和病理发现43个癌灶,RII发现34个,灵敏度为79.1%。9例肝外腹腔内转移灶20个,RII阳性15个,灵敏度为75%;20例原发性肠癌中,16例原发灶出现放射性浓集,灵敏度为80%。18例无肝外腹腔内转移中15例显像阴性,特异性为83.3%。结论:99mTc-C50RII对原发性肠癌、肠癌术后复发的诊断以及肠癌转移灶的发现均有意义。
