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.

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.

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.

6." TOTI " Method for Difficult Orotracheal Intubation in Adult Patients.
Korean Journal of Anesthesiology 1991;24(2):379-383
This report is a prospective study comparing conventional direct laryngoseopy with tube-over-tube intubation ("TOTI") method in 42 male patients, whose tracheas were difficult to intubate. ("TOTI") method using two different-sized endotracheal tubes, the newly devised technique has not been mentioned yet. And the comparative studies have not been performed to evaluate relative efficacy, speed, or incidence of complications for the conventional versus "TOTI" method in endotracheal intubation. Overall number of attempts (mean+/-SE) in conventional group was 3.62+/-0.37(range; 1-8), while "TOTI" one was 1.1+/-0.07 (range; 1-2). The time required for intubation ranged from 25 to 64 seconds in TOTI group and 37 to 2015 sec in conventional one, average (mean+/-SE) 37.19+/-1.87 and 542.71+/-111.54sec, respectively. No complications of endotracheal intubation occured in "TOTI" group, whereas in coventional one there occurred fourteen patients with sore throat, seven with hoarseness and five with temporary short-lived dysrhythmia.

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.

Secondary osteoarthritis of hip joints is a common disease and is frequently followed by chronic sublexation and dislocation. Twenty four case of the secondary osteoarthritis associated with chronic subluxation and dislocation of the hip joints were evaluated with plain radiography and computed tomography. We retrospectively analyzed 1) the ossification and calcification of the acetabular labrum, 2) the thickeness of the quadrilateral plate of the ilium, and 3) anteroposterior diameter of the acetabulum. The changes of the hip joints in subluxation (n=14) revealed ossification of the acetabular labrum in 12 cases (86%), thickening of the quadrilateral plate of the ilium in 11 cases (78%) but anteroposterior diameter of the acetabulum was not changed. The changes of the hip joints in dislocation (n=10) revealed no evidence of the ossification of the acetabular labrum, thickening of the quadrilateral plate of the ilium in 10 cases (100%) and decreased anteroposterior diameter of the acetabulum. We conclude that CT findings of subluxation and dislocation of the hip joints can be helpful in the evaluation of the secondary osteoarthritis of the hip joints.

Syphilitic involvement of the stomach often takes the appearance of neoplastic conditions. We describe the radiological findings of syphilitic gastritis. A 36-year-old man was diagnosed with gastric cancer by upper GI and CT, but syphilitic gastritis was confirmed by endoscopy and upper GI series performed after penicillin therapy, We report a case of syphilitic gastritis presented as advanced stomach cancer by clinical, endoscopic and radiological study.
