Evaluations of residual renal function and the therapeutic effectiveness in renal tuberculosis have largely been dependent on intravenous pyelogram or Contrast-CT scan, even though, exact renal function are not evaluated with there methads. 99mTc-DMSA is a radiopharmaceutical that is trapped in the functioning tubular cells of the kidney and therefore, quantitative renal function could be evaluoted by ineasuring the counts of renal radioactivity and concomittant evaluation of renal morphology could be passible with the analog imapes of the radioactivity. The authors retrospectively analyzed 99mTc-DMSA scans of 75 kidndys of 67 patients with confirmed renal tuberculosis. We classified the morphologies of tuberculous kidneys as 6 types. We classified the morphologies of tuberculous kidneys as 6 types such as the type with small cortical defect, with parenchymal ulcerocavernous lesions, ulcerocavernous fistula to pelvis, mass-like defects, contracted kidney with ureter visualization, and the type with nonvisualization of kidney, corresponding to the characters of renal tuberculous pathogenesis with abscess formation, ulcerocavernous fistula, and fibrosis, and correspondings to the renal anatomy with parenchyma, and pelvocalyceal collecting system. Their mean residual renal functions measured with 99mTc-DMSA uptake rates were 19.0%, 18.4%, 7.9%, 12%, 4.1%, 3.4% respectively.

PURPOSE: The purpose of this study was to evaluate the role of glucose transporter in peritoneal glucose and fluid transport. METHODS: Male Sprague-Dawley rats were used. 5mL normal saline with(CB) and without(C) Cytochalasin B(1 muM) was intraperitoneally injected once. From the next day 25 mL commercial dialysis solutions containing 4.25% glucose was injected into the peritoneal cavity twice a day for 8 weeks in a half of each group(CB-IP, n=6 and C-IP, n=8). The other half of each group served as control without IP(C- Control, n=7 and CB-Control, n=7). A 2 hour dwell study was performed using dialysis solutions containing 4.25% glucose. Intraperitoneal volume(IPV) after 2 hours of dwell was measured and peritoneal fluid absorption rate(Qa) was calculated as RISA disappearance rate. Dialysate glucose amount remaining after 2hour dwell(DGA) was calculated and expressed as % of the initial value. RESULTS: IPV was significantly higher in CB than in C in both IP and Control. IPV was significantly lower in C-IP than in C-Control and CB-IP while it was similar between CB-Control and CB-IP. Qa was significantly higher in IP than in Control. DGR was significantly higher in CB than in C and in control than in IP. CONCLUSION: Longterm peritoneal exposure to high glucose dialysis solution increased peritoneal glucose absorption and decreased ultrafiltration volume in rat. A single IP use of glucose transporter inhibitor attenuated increased glucose absorption and decreased ultrafiltration after longterm peritoneal exposure to dialysate.

Dieulafoys lesion consists of abnormally large gastric submucosal artery which ruptures into the stomach causing massive or recurrent intragikstric bleeding. The lesion is very small and easily overlooked even at laparatomy and aan only be correctly diagnosed by endoscopy or arteriography if the patient is actively bleeding. Three patients who were admitted with bleeding of upper gastrointestinal tract and eventually diagnosed as having Dieulafoys lesions were analysed. All were men with age range of 44 to 55 years. All patient were asymptomatic before presenting with hematemesis. Two of the three patients had had history of upper Gl bleeding. One patient used analgesics daily for ureteral colic and two patient drank alcohol excessively. Gastroscopy was performed during the bleeding episode in all three patients. Dieulafoy's lesion was seen in all three cases and in the second case, there was concomittent diffuse petechia in the whole stomach. The lesion was situated on the posterior wall of upper body in one, on anterior wall of upper body in another, lesser curvature side of gastric fundus in the other case. All three patient underwent laparotomy for persistent bleeding and the lesion was suture ligated only in two patients while in one patient vagotomy and pyloroplasty was added. Resection biopsy was performed in two cases and both revealed only normal gastric mucosa. All patients discharged after complete recover.

Polyploid cells in the urinary sediments often give an erroneous clinical judgement in cases of post-pelvic irradiation follow-up, but their nature and evolution have remained unclarified. An experimental induction of polyploid cells in the transitional epithelium of the urinary bladder was carried out in Sprague-Dawley rats by administration of 3,000 rads in a single dose, and their sequential morphological changes were analysed under light and electron microscopes. 1. The acute post-irradiation changes of transitional epithelial cells were manifested with two consecutive phases of degenerative process ; the early lesion started to appear from the first day after irradiation and diminished partly at the 7th day; the later changes became enhanced progressively from the 2nd week and maximized at the 3rd week, but regressed thereafter . 2. The general histological alterations of the transitional epithelial cells in the acute stage were characterized by cytoplasmic vacuolization due to profound widening of intercellular cisternal spaces and dilatation of smooth endoplasmic reticulum aside from severe disruption of mitochondria and increase of lysosomes, especially in the superficial and intermediate cells, and by eventual outcome of cell death by nuclear pyknosis and karyorrhexis. 3. The polyploid cell change was demonstrated as a spectrum of the later alterations of acute irradiation injury to the basal layer cells, and appeared early from the 2nd week and regressed after the 4th week. 4. Based on their increased size and nuclear abnormalities, those polyploid cells exhibited features of both amitotic nuclei and cytoplasmic degenerative processes ultrastructurally, and in the acute phase the nuclear indentation and lobulation were associated with increased amount of heterochromatins and margination together with nucleolar enlargement and increase in number. 5. The above cells started to regress thereafter, being terminated by nuclear pyknosis and karyolysis, and numerical reduction of the polyploid cells was accompanied concomitantly with basal (reserve) cell hyperplasia of the remained epithelium. It is of the author's assumption that the polyploid cell phenomenon induced by irradiation onto the transitional epithelium of the urinary bladder is a transient manifestation of irradiated amitotic basal cells during the later phase of acute post-irradiation injury and is subsequently removed out by nuclear pyknosis and karyolytic processes.

Pseudothrombocytopenia is an in vitro phenomenon usually associated with anticoagulant (ethylene diaminetetraacetic acid, EDTA)-dependent IgG platelet agglutinins. Two cases of pseudothrombocytopenia due to EDTA-independent agglutinins are reported. The fingerstick blood smear showed platelet clumping as well as EDTA, citrate and heparin samples. In a case with malaria, serum IgM was 985 mg/dL and serum protein immunofixation demonstrated an additional IgM band which disappeared together with platelet clumping a month later. The increased immunoglobulin (especially, IgM) appeared to be associated with platelet agglutinin. Another case had cold reactive agglutinin because the electronic platelet counts were dependent on temperature. These cases illustrate that pseudothrombocytopenia may be caused by more than one type of agglutinin and can be confirmed by using a direct fingerstick, keeping the sample warm, or drawing the blood into another anticoagulant.

Hallervorden-Spatz disease (HSD) is a rare, progressive, autosomal recessive hereditary disorder characterized by pyramidal and extrapyramidal signs, speech disturbances, mental deterioration and retinal degeneration during childhood or adolescence. In late-onset form after the age of 20, parkinsonian features may be the predominant clinical manifestation. Meanwhile, involuntary tongue movements are rare and poorly understood, which have been reported in tardive dyskinesia, neuroacanthocytosis, chronic epilepsy, and after head trauma. We report a case of a patient with 'fly catcher's tongue' as a major clinical presentation, accompanied with mild parkinsonism, and typical MR findings of HSD.

PURPOSE: It is essential to know the functional and morphologic changes of the larynx in the evaluation of laryngeal lesions. Conventional CT which has relatively long examination time is not suitable for this aim. The purposes of this study are to evaluate the capability of spiral CT in the dynamic study of the larynx and to know whether this new technique can replace conventional laryngography or not. MATERIALS AND METHODS: Five healthy volunteers and 20 patients with laryngeal lesions underwent spiral dynamic CT scans with 3-dimensional reconstruction of the mucosal surface. A series of spiral CT scans were done while the volunteers performed various laryngeal positions to obtain the functional and morphologic information. The maneuvers used were:quite breathing, "E" phonation, Valsalva maneuver, modified Valsalva maneuver, and a new method of our own, "modified breath holding" technique. The patients were scanned when in quite breathing. Additioal scans were obtained by using the "modified breath holding" technique. RESULTS: The dynamic study with spiral CT could provide high resolutional images which nicely depicted the mobility of vocal cords and the mucosal changes of the laryngeal cavity in both healthy volunteer and patient groups. In patient group, the new "modified breath holding" technique was easier and more reproducible than other maneuvers. CONCLUSION: Spiral CT allows a dynamic study of the larynx and can be a new alternative of laryngography.

BACKGROUND: Negative U wave is frequent maker of systemic hypertension, aortic or mitral regurgitation and myocardial ischemia. This study was undertaken to determine the diagnostic significance of exercise-induced negative U wave in coronary artery stenosis. METHOD: 72 patients(46 men and 26 women ; 24~66 years of age) with chest pain were analysed with exercised-induced negative U wave and coronary angiographic finding. RESULT: Exercise-induced negative U wave was seen in 14 patients(19%). Among 14 patients with exercise-induced negative U wave, the predictive value of significant coronary artery stenosis(> or =75% stenosis of major coronary artery) was 71%, Exercise-induced negative U wave is more prevalent in patients with significant coronary artery stenosis(p<0.05). CONCLUSION: Exercise-induced negative U wave is a good marker of significant coronary artery stenosis.

Cardiac rupture after blunt chest trauma is a relatively uncommon diagnosis, and it is associated with a very high mortality rate. A 41-years-old man crashed his car into a guardrail and he was then transported to hospital. Although unstable vital signs are the most common symptoms of cardiac injury, this patient had stable vital signs. The chest CT scan showed pericardial effusion, and echocardiography did not clearly reveal cardiac tamponade, but the right atrium was slightly collapsed. Cardiac injury was suspected, and surgery was commenced for obtaining the diagnosis and treatment. A 2 cm laceration at the junction of the left atrium and the left inferior pulmonary vein was discovered and this was repaired with 4~0 Polypropylne monofilament sutures. We report here on the successful management of a patient with left atrial rupture following blunt chest trauma.
