The use of intravacular catheterization for both diagnostic and therapeutic purposes increased the incidence of iatrogenic foreign bodies, which might cause many complications such as cardiac arrythmias, perforation of cardiac chamber or blood vessels, sepsis and thromboembolism. The authors experienced 5 cases of successful retrieval of intravascular iatrogenic foreign bodies: three cases of subclavian catheter wire and two cases of subclavian catheter. Subclavian catheter was introduced into right subclavian venous route for hyperalimentation or central venous pressure monitoring. The foreign bodies were located in superior vena cava and inferior vena in four cases and in left main pulmonary artery in the other case. We have successufully removed the foreign bodies by interventional procedures. The loop-snare technique is a safe and effective method for retrieval of iatrogenic foreign bodies in great vessels.

Pseudo-Bartter syndrome is a rare medical disease of the kidney characterized by normal blood pressure, hypokalemic metabolic alkalosis, hyperreninemia and hyperaldosteronism with drug history of diuretics. We report US, CT and MRI findings of a patient with clinically proved pseudo-Bartter syndrome. The patient was a 37-year-old woman with a history of long term ingestion of the diuretics(furosemide) for 20 years. Renal US revealed hyperechoic renal medulla at both kidneys. The resistive index(RI), calculated from the duplex doppler waveform is 0.61. Unenhanced CT revealed faint high attenuation along the medulla. Tl-weighted MRI revealed indistinct corticomedullary differentiation.

Chest CT is the most useful modality in the diagnosis of primary lung cancer, particularly in patients with recurrent pneumonia which are resistant to antibiotic therapy and in high risk age groups for cancer, The purpose of this examination is to assess the usefulness of CT in pneumonia types of lung cancer. The authors retrospectively analyzed 15 histologically proven cases of pneumonic type lung cancer, which had no evidence of primary lung mass, mediastinal lymphadenopathy or other metastatic lesion on piain chest radiography. On CT scan, a primary lung mass was identified in 13 patients(87%, bronchial obstruction was identified in 12 patients(80%), and metastatic foci was found in the bone(one patient), liver(one patient), and spleen(one patients). In Conclusion, CT scan is a useful method to detect the mediastinal lymphadenopathy or pulmonary mass and also should be the initial radiolographic procedure for diagnosis of lung cancer in patients with recurrent pneumonia on simple chest radiography.

PURPOSE: The number of resected lymph nodes can influence the current N staging. This study examined the significance of the metastatic lymph node ratio on the survival of patients with pT2 gastric cancer. METHODS: The records of 176 patients who had undergone curative gastrectomy and diagnosed with pT2 gastric cancer by pathology, between February 1990 and October 2002 were retrospectively reviewed. Those patients with other organ metastases or those who had undergone a dissection of less than 15 lymph nodes were excluded. The clinicopathologic prognostic variables were evaluated using the SPSS statistical program. RESULTS: There were 115 men and 61 women with a mean age of 59 years. The median survival period was 93 months (2~184 months). Metastatic lymph nodes were found in 100 cases (56.8%), a mean of 34.6 lymph nodes were dissected, a mean of 3.2 lymph nodes metastasized, and a mean metastatic lymph node ratio of 0.09 was found. According to the UICC TNM classification, the number of stage IB (N0) cases was 76 (43.2%), stage II (N1) was 74 (42.0%), stage IIIA (N2) was 18 (10.2%), and stage IV (N3) was 8 (4.5%). The overall 5-year survival rate was 75.2%. According to the UICC TNM classification, the 5-year survival rate was stage IB, II, IIIA, and IV was 88.6%, 74.3%, 39.5%, and 33.3%, respectively. The metastatic lymph node ratio (nR) was divided into 4 categories; nR0 (76) = 0, 0

OBJECTIVE: Lectins are cell-agglutinating and sugar specific proteins or glycoproteins of non-immune origin that precipitate glycoconjugates having saccharides of appropriate complementarity. Because of these properties, plant lectins have been used to help characterize the carbohydrate moieties of glycoproteins in the zona pellucida (ZP) of several mammalian species including pigs. Treatment of oocytes with various lectins blocks sperm binding to the ZP in various mammalian species. This study was undertaken to examine the distribution of sugar residues in the ZP of pig oocytes matured in vitro and the ability of spermatozoa to bind to ZP and in vitro penetration in oocytes treated with fluorescein isothiocyanate (FITC)-labelled lectins. MATERIALS AND METHODS: The lectins of Banderiaea simplicifolia (BS-II, bind to beta-D-Nacetylglucosamine), Canavalin ensiformis (Con A, bind to alpha-D-Mannose), Lens culinaris (LCA, bind to alpha-D-Mannose), Ricinus communis (RCA-I, bind to beta-D-Galactose) and Ulex europaeus (UEA-I, bind to alpha-L-Fucose) were examined for spermatozoa penetration, binding capacity to ZP and distribution of lectins. RESULTS: The penetration rates were significantry (p<0.05) higher in control oocytes (63%) than those treated with all lectins, but penetration rates (40~49%) were simililar in group treated with lectins. The incidence of monospermy was similar in oocytes untreated and UEA-I, but it was higher in oocytes treated with BS-II, Con A, RCA-I and LCA. The porcine oocytes cultured for 48 h in TC-199 medium were freed from cumulus cells and treated for 30 min with fluorescein isothiocyanate-labelled lectins. When examined under fluorescein illumination, higher (p<0.001) proportions of oocytes showed fluorescein of zona pellucida after treatment with Con A (93%), LCA (93%) and RCA-I (100%) than BS-II (37%) and UEA-I (50%). All of the oocytes treated with RCA-I exhibited strong fluorescein in the outer region of the zona pellucida while those treated with LCA exhibited strong fluorescein throughout the zona pellucida. BS-II bounded mainly to the outer region and UEA-I bounded mainly to the inner region of the zona pellucida, with either strong or weak fluorescein. At 120 min after insemination in vitro, fewer spermatozoa were bound to the zona pellucida of the oocytes treated with BS-II, Con-A and RCA-I. Of the lectins, Con A most inhibited sperm binding. CONCLUSIONS: These results suggest that beta-D-Galactose residues in the porcine zona pellucida may act as primary sperm receptors and inducers of the sperm acrosome reaction and these sugar residues may be involved in the block to polyspermy.

A case of xanthogranulomatous oophoritis is presented in a patient who had a 3-month history of intrapelvic mass protruding into the vagina. The sonographic findings are a well defined mass shadowing lower echogenicity than the echo of the uterus at the posteosuperior aspect of the uterus. The CT findings are an enhancing solid mass with central necrosis containing a multiseptated cystic component.
