PURPOSE: Prostatic tumor induced gene-1 (PTI-1) is a mutated human EF-la and putative prostatic carcinoma tumor-inducing oncogene, that is differently expressed in prostatic cancer and benign prostatic hyperplasia. And, it is more sensitive marker than prostate- specific antigen (PSA) for detecting human prostate cancer in the bloodstream. This study invastigated the expression of PTI-1 in paraffin embedded tissue of prostatic carcinoma, prostatic intraepithelial neoplasia, and benign prostatic hyperplasia using in situ PCR. MATERIALS AND METHODS: we evaluated expression of PTI-1 in prostatic carcinoma with prostatic intraepithelial neoplasia (PIN) of 32 cases, benign hyperplasia of 20 cases, high grade transitional cell carcinoma of 10 cases and colon cancer of 10 cases for control group. Also, the immunohistochemical staining for PSA was performed to comparison with clinical value of PSA. RESULTS: The serum level of PSA was closely related to stage and Gleason score (p < 0.05). However, the results of immunohistochemical stains were variable to stage and Gleason score. PTI-1 using in situ PCR expressed in 50% of prostatic carcinoma, 41% of prostatic intraepithelial neoplasia, 10% of benign hyperplasia and colon cancer (p < 0.05). No expression is observed in transitional cell carcinoma. In prostatic carcinoma, PTI-1 expressed in 43.8% (7/16) of stage II, 50.0% (5/10) of stage III, and 66.7% (4/6) of stage IV (p<0.05). In PIN, expression of PTI-1 was similar to prostatic carcinoma (p<0.05). CONCLUSION: PTI-1 represented a relatively sensitive marker for prostatic carcinoma and PIN, indicator of prostatic carcinoma progression.

BACKGROUND: DNA topoisomerase II-alpha is linked with active cell proliferation in mammalian cells. The aim of this study was to examine the relationship between the expression of DNA topoisomerase II-alpha as a proliferating marker, and the expression of Ki-67 and apoptosis in urothelial carcinoma of urinary bladder based on World Health Organization/International Society of Urological Pathology (WHO/ISUP) consensus classification. METHODS: 73 urothelial carcinomas of the urinary bladder after transurethral resection and 25 carcinomas after radical cystectomy were investigated for histologic grading based on WHO and WHO/ISUP consensus classification. Formalin fixed, paraffin embedded tissue of 98 specimens from 73 patients were immunohistochemically stained for DNA topoisomerase II-alpha and Ki-67, and in situ TdT-mediated dUTP-biotin nick end labeling method for evaluation of apoptotic cells was performed. For each case, a DNA topoisomerase II-alpha, Ki-67, and apoptotic indices were determined. RESULTS: The histologic grades of 73 cases based on the WHO grading system were 21.9% (16 cases) in grade 1, 65.8% (48 cases) in grade 2, and 12.3% (9 cases). 5.5% (4 cases) of papillary neoplasm of low malignant potential, 47.9% (35 cases) of urothelial carcinoma of low grade, and 46.6% (34 cases) in urothelial carcinoma of high grade were reclassified using the WHO/ISUP consensus classification. Histologic grades based on two grading systems were correlated to invasion and stage (p<0.05). DNA topoisomerase II-alpha, Ki-67, and apoptotic indices were correlated to histologic grades based on two grading system and invasion. Also, the correlation of DNA topoisomerase II-alpha and Ki-67 indices, and DNA topoisomerase II-alpha and apoptotic indices were significant, respectively. CONCLUSIONS: DNA topoisomerase II-alpha appears to be an useful marker for assessing the proliferation potential of urothelial carcinoma of in the urinary bladder.

The globus symptom is a condition in which a patient, often middle aged women, complains of a lump andchocking sensation in the throat, Functional disturbance of the cricopharyngeal muscle, rendering it incapable ofrelaxing during swallowing, has long been recognized as a cause of globus symptom and dysphagia. We wanted to findout how often and to what extent distrubed relaxation of the cricopharyngeal muscle can be seen in patients withglobus symptom with routine examination and video esophagogram. The results were as follows: 1. Male : femaleratio was 1:2.4. 2. Globus symptom was most frequent in the age group between 30-39 of female. 3. Organic lesionswere seen in 43.6%(24 Pts) of globus patients. 4. Cricopharyngeal muscle was visualized in 29.1%(16Pts), esophageal diverticulum in 3.6%(2 Pts) and degenerative spondylosis in 3.6%(2 Pts). 5. Incidence of visualizationof cricopharyngeal muscle were higher in male group (50%) than female one (20.5%). 6. Cricopharyngeal muscle wasmost frequently visualized on early swallowing phase(12/16 Pts).

This study aims at analyzing the articulator of human body and its composition using the Magnetic Resonance Image (MRI, 0.5 Telsa). The MRI images were photographed for 1cm per every cm of human body using TR 600ms and TE 20ms spin-echo sequence. For this test, 6 healthy male subjects were sampled. The subject's heights and weights were measured before photographing and then their entire bodies were photographed in the MRI whole body scanner which has a 56cm diameter. It took 90~120 minutes to scan every subject's body during scanning the subjects were allowed to put their both hand beside their femurs. According to his height, each subject were photographed for 180~200 MR slices and every image was analyzed on the tracing paper via X-ray reading View Box. Then, the traced images were all volumized through computer scanner and CAD program, and thereupon, each volume was multiplied by its density coefficient. The results of study can be summarized as follows ; The mass of the bones occupied 8.41±0.62kg, which accounted for 11% of the body mass. The femurs accounted for 19.73±2.73% of the bone mass in terms of bodily articulation. The muscle occupied 39.70±5.28kg which accounted for 51.28±8.98% of the body mass. The part which has the richest muscle mass was femur which accounted for 33.93±5.58% of entire muscle mass. The fat accounted for 24.61±11.6% of the body mass, among which the back waist including inside intestinal fat occupied 30.66±3.64%. It was suggested through this study that MRI analysis is the most suitable method to evaluate the composition of human body and that the data acquired through MRI analysis may apply as references to other indirect or estimated evaluation of human body.

Forty cases of infiltrating duct carcinoma of the breast were examined immunohistochemically for expression of TGF-beta and angiogenesis in order to analyze significant correlation with prognostic parameters including tumor size, axillary lymph node metastasis, clinical stage, histologic grade, estrogen receptor and progesterone receptor status. The TGF-beta expression was observed in tumors center and advancing edges of tumors. To determine microvessel density for angiogenesis, we stained endothelial cells for Factor VIII related antigen and counted microvessel within tumor. The results were as follows: 1) The strong immunohistochemical expression of TGF-beta and higher counts of microvessels were observed in advancing edges of tumors (p<0.05). 2) The TGF-beta expression in the advancing edges of tumors was closely related to clinical stage and presence of axillary lymph node metastasis (p<0.05). 3) The mean microvessel counts were significantly higher in tumors from patients with axillary lymph node metastasis and increased with increasing clinical stage (p<0.05). 4) The TGF-beta expression was not related to histologic grade, estrogen receptor and progesterone receptor status(p>0.05). Therefore, the results suggested that the TGF-beta expression and angiogenesis in infiltrating duct carcinoma of the breast may play an important part in prognostic factors, closely related to the lymph node metastasis and clinical stage.

PURPOSE: To evaluate the relationship between spinal instability and ossification of the posteriorlongitudinal ligament(OPLL). MATERIALS AND METHODS: In 70 patients(M:F=45:25, mean age=53years) diagnosed as OPLLon the bosis of with surgical operation field findings and radiological evaluation[ plain film(n=70), CT(n=64),MRI(n=55) ], involved levels were the cervical spine(n=32), lumbar spine(n=23), and both the cervical and lumbarspine(n=15). Spinal instability was radiologically diagnosed as horizontal displacement of one vertebra by anotherof more than 3.5mm, or a difference in rotation from either adjacent vertebra by more than 11degree in lateralcervical spine and a difference of more than 1.5mm from the posterior body margins to the point of intersection oftwo lines drawn parallel to the opposing segmental endplate in extension lateral lumbar spine. We divided OPLLinto group I(continuous, segmental, mixed) and group II(retrodiscal), and compared spinal instability in these twogroups. RESULTS: In cervical OPLL, group I comprised 33 cases and group II 14. In group I, spinal instability wasnoted in 8/33 cases(24%)) or 10/123 segments(8.1%). Spinal instability in group II, on the other hand, was foundin 13/14 cases(93%) or 17/26 segments(65%). Ossification occurred at the retrodiscal level in 37 cases, byt incase was continuous. In group II, spinal instability was found in 25 of 37 cases(69%), oe in 29 of 55segments(53%). CONCLUSION: Compared to other types of OPLL, the frequency of retrodiscal OPLL in association withspinal instability was high. Spinal instability may thus be the most important cause of retrodiscal OPLL.

PURPOSE: The purposes of this study were to analyze the MR findings of medulloblastoma, and to evaluate the subarachnoid dissemination and the significance of contrast enhanced MR of brain and spine for tumor.. MATERIALS AND METHODS: The preoperative brain MR studies of 18 patients (9 males, 9 females;mean age, 9.4 years) with surgically proved medulloblastomas were retrospectively reviewed to characterize these neoplasms with regard to their location, size, MR signal intensity, appearance after contrast enhancement, presence of cyst and necrosis, subarachnoid dissemination, and other associated findings. In 14 patients postoperative spine MR studies were evaluated for staging and therapeutic planning. RESULTS: The most frequent location of medulloblastoma was the inferior vermis and the mean tumor size was 4.1 x 3.6 x 3.9 cm. On Tl-weighted image, medulloblastomas generally had low to intermediate signal, predominantly hypointense relative to white matter. On T2-weighted image, medulloblastomas showed modetately high signal, hyperintense relative to white matter. Inhomogeneous contrast enhancement was demonstrated in 13 patients(72.2%) after injection of gadopentetate dimeglumine(Gadolinium). Cyst and necrosis within the tumor were visualized in 15 patients(83.3%). Subarachnoid disseminations of medulloblastomas were noted in 11 patients(61.1%), of which 6 demonstrated intracranial and 2 intraspinal dissemination. Three had both intracranial and intraspinal dissemination. In nine cases with intracranial lesions, there were intraparenchymal mass formation(7), subarachnoid nodules(5), infundibular lesions(2) and diffuse gyral enhancement(I). In five cases with intraspinal lesions, there were extramedullary intradural small nodules(3), central canal nodules(2), intradural masses(I)and fine nodular and sheet-like leptomeningeal enhancement(1). Other associated findings included intratumoral hemorrhage(11.1%), per/tumoral edema(44.4%), tonsillar herniation(44.4%), hydrocephalus(88.9%) and calcification(44.4%). CONCLUSION: Medulloblastomas revealed low to intermediate signal intensity on Tl-weighted image and intermediate to moderately high signal intensity on T2-weighted image, relative to cerebellar white matter. Medulloblastomas were solid tumors with cystic necrosis, which showed inhomogeneous enhancement and subarachnoid disseminations to the intracranial and intraspinal spaces after Gd-DTPA enhancement. Gd-enhanced MR of brain and spine was an useful diagnostic modality in preoperative diagnosis and in staging of postoperative cases of medulloblastomas, which was superior to postcontrast CT or precontrast MR.
