Pertutaueous transluminal angioplasty is the treatment of choice for renovascular hypertension in cases due to the renal vascular occlusion which is not severe enough to pass dilatation catheter. The advantages of percutaneous transluminal angioplasty are the use of local anesthesia, its noninvasiveness without surgical risk, feasibility of repetition and shorter hospital days compared with surgical methods. We are presenting a case of renovascular hypertension due to atherosclerosis cured by percutaneous transluminal angioplasty with the review of literatures.

Severe irradiation on head may result functional alterations of central nervous system. In this study, the irradiation effect on the cerebellar cortex following heavy X-irradiation on head was studied ultrastructurally. Radiation was produced with the linear accelerator ML-4MV[Mitshubishi Co.], and rats weighing about 200gm each were exposed their heads within the radiation areas of 30cm x 30cm, under the radiation distance of 80cm, and with the radiation depth of 1.2 cm. Radiation doses were 3,000rads or 6,000rads, respectively. Animals were sacrificed on 6 hours, 2 days or 6 days following the radiation. Under anesthesia, animals were perfused with 1% glutaraldehyde-1% paraformaldehyde solution. Two hours after the perfusion, brain were taken out and refixed over night in the perfusion fixative. Small blocks of cerebellar hemispheric cortices were refixed 2 hours in 2% osmium tetroxide solution. Fixed tissues were dehydrated in alcohol, embedded in araldite mixture, and cut with ultratome. Ultrathin sections were contrasted with uranyl acetate and lead citrate solutions, and observed with electron microscope. The results obstained were as follow : 1. On 6th hour following X-irradiations, many cerebellar cortical neurons showed increased electron densities, more complicated nuclear infoldings, depletion of synaptic vesicles, expansion of astroglial territories, etc. 2. On 2nd day following X-irradiations, many organelle-rich cells such as Purkinje cells and Golgi cells were darkly degenerated. Numerous myelin figures formed by the cisternal fusions of Golgi apparatus or granular endoplasmic reticula were observed. Cytoplasmic processes of activated astroglial cells were expanded around capillaries and between granule cells. 3. On 6th day following X-irradiations, morphology of neuropil and neurones in the cerebellar cortex was generally restored, except the expanded territories of astroglial cells. From the above results, it was concluded that the release ofneurotransmitters and transcapillary leakage of blood substance were occurred on 6 hours after heavy X-irradiations. And severe alterations were produced on 2 day after X-irradiation, but the condition was generally restored on 6th day following X-irradiation.

BACKGROUND: In patients with coronary artery disease, dysfunctional hypoperfused myocardium at rest may represent either nonviable or viable hibernating myocardium. Two-dimensional echocardiography can detect regional wall motion abnormalities resulting from myocardial ischemia by dobutamine infusion. The purpose of the present study was to identify the prediction of improvement of regional left ventricular (LV) function after surgical revascularization. MATERIALS AND METHODS: Sixteen patients with chronic regional LV dysfunction underwent dobutamine stress echocardiography (DSE) (dobutamine: baseline, 5, 10, 20microgram/kg/min) before coronary artery bypass grafting (CABG) and underwent echocardiography at least 2 months after CABG. RESULTS: All patients were male with mean age of 58 years ranging from 42 to 73 years. The mean LV ejection fraction was 41.8% with a range from 19% to 55%. During DSE, there were no complications, also, there were no operative morbidities or mortalities. Improvement of wall motion within the dysfunctional myocardium was found in 8 (50%) of 16 patients in DSE. Among them, 6 patients (75%) showed functional recovery after CABG. Another 8 patients did not show improvement of wall motion in DSE. But among them, 3 patients (38%) showed functional recovery after CABG. 84 dysfunctional segments were found in 256 segments of 16 patients. Improvement of wall motion was found in 34 of 84 segments in DSE. Among them, 23 segments (74%) showed functional recovery after CABG. Another 53 segments did not show improvement of wall motion in DSE. But among them, 12 segments (23%) showed functional recovery after CABG. The sensitivity and specificity of DSE for the prediction of postoperative improvement of segmental wall motion were 66% and 84%, respectively. The positive and negative predictive value of DSE were 74% and 77%, respectively. In patients with chronic regional LV dysfunction, think that DSE is a good predictor of the improvement of dysfunctional segments after CABG.

PURPOSE: Recent advances in the methods of treating cancer in young patients have led to both an increased frequency of CNS complications as well as prolonged life expectancy. We intend to analyze the clinical aspects and laboratory findings of patients with CNS complications during and after treatment. METHODS: We reviewed the medical records of 174 childhood cancer patients treated with chemotherapy admitted to the Dept. of Pediatrics, Keimyung University Dongsan Hospital, from January 1995 to November 2002. Among them, 15 cases with CNS complications were investigated in this study. RESULTS: CNS abnormalities were found in 13 patients by CT or MRI during treatment such as leukoencephalopathy(n=7), mineralizing microangiopathy(n=4), brain infarction(n=3), intracranial hemorrhage(n=1), and hypoxic ischemic encephalopathy(n=1). It was found that two patients had two or more CNS abnormalities. Two patients who had no imaging abnormalities had convulsions, possibly after the addition of intrathecal methotrexate. The patients with intracranial hemorrhage and brain infarction had rapid and fatal clinical courses. The hypoxic ischemic encephalopathy following electrolyte imbalance completely recovered after correction of electrolyte. CONCLUSION: The CNS complications that occur during and after chemotherapy influence prognoses significantly, and remain neurologic sequelae. Therefore early diagnosis and prophylaxis for CNS complications and regular physical examination of patients who have recieved cancer therapy are strongly recommended.

The two most common causes of acute arterial occlusion are embolism and thrombosis in sity. They are mainly originated from the cardiovascular sources. About 70-80 per cent of occlusions occur in the axial limb vessels. Therapeutic options include supportive measures, pharmacologic treatment, surgery, and non-operative interventions. There have been several successful case reports using percutaneous aspiration thromboembolectomy with the advent of new instruments and technical imprevement. We report a case of 70-year-old male with acute anterior wall myocardial infaction who experienced acute embolic arterial occlusion of the left popliteal artery from mural thrombus in the left ventricular apex. It wan managed successfully by percutaneous aspiration thromboembolectomy.

OBJECTIVE: To investigate the activities of upper trapezius and deltoid muscles in shoulder abduction in full can and empty can position in rotator cuff tear patients. METHOD: Twelve subjects with right rotator cuff tear patients participated in this study. Each subject performed scapular plane abduction with humeral external rotation (full can position) and with humeral internal rotation (empty can position). Electromyography (EMG) was recorded with surface electrodes at the both upper trapezius, anterior, lateral, and posterior deltoid muscles during shoulder abduction. The EMG activity of each muscle was normalized according to the highest EMG activity during a maximum manual muscle test for the corresponding muscle. RESULTS: Muscle activities of the lesion side's upper trapezius and lateral deltoid were significantly greater than those of the normal side in full can position. In empty can position, the activities of upper trapezius, anterior, and lateral deltoid increased in lesion side. In comparison between full can and empty can exercises, over 30degrees abduction arcs, empty can exercise showed increased muscle activities of upper trapezius and all deltoid muscle in lesion side. In contrast, anterior and lateral deltoid only showed increased in the muscle activities under empty can exercise in sound side. CONCLUSION: Rotator cuff tear is involved in changed the activities of upper trapezius and deltoid muscles. And these results suggested that in rotator cuff tear patients, the changed pattern of muscle contraction should be considered in shoulder exercise.

PURPOSE: To evaluate the efficacy of the postoperative oral antibiotics in acute appendicitis. METHODS: This study compared 126 patients diagnosed with appendicitis in 2004, who did not take oral antibiotics after the postoperative treatment (group 2), with 119 patients diagnosed with appendicitis in the year of 2003, who did take oral antibiotics after the parenteral postoperative antibiotics regimen (group 1). RESULTS: The clinical, operative, and bacterial outcomes were similar. Only one infectious complication was detected in each group (group1; 1/119, group2; 1/126). CONCLUSION: This study suggests that adding a course of oral antibiotics, after completing a course of parenteral antibiotics, does not decrease The rate of postoperative infectious complications in appendicitis patients.

This study was undertaken to investigate the in vivo effects of cyclophosphamide (CY) on subpopulations of macrophages and other types of immune cells including dendritic cells (DCs) as well as on ICAM-1 expression in the spleen of rats. After a single dose of CY (150 mg/kg) was administered to Sprague-Dawley rats by intraperitoneal injection, the rats were sacrificed at 1, 3, 7, 14 and 28 days. The immunocytochemical characterization of the tissues were carried out using the monoclonal antibodies W3/25, OX8, HIS24, 8A2, OX6, OX62, ED1, ED2, ED3, and TLD-4C9 for analysis of macrophage subpopulations, DC(s), CD4(+) and CD8(+) T cells, B cells and ICAM-1 expression in cryostat-cut sections. CY exhibited a profound immunosuppressive effect on CD4(+) and CD8(+) T cells as well as B cells as was expected. However, it was found that CY induced an increase in number of certain subpopulations of macrophages, including ED1(+), ED2(+) and ED3(+) macrophages. Contrarily, CY elicited a decrease in number of DCs. CY induced a conspi-cuous upregulation of ICAM-1 on certain populations of leukocytes. This increased expression of ICAM-1 after CY treatment appears to be related with the recruitment of certain populations of leukocytes. Most of these features began to appear from the first day and reached the maximun on the third and especially, the seventh day, but two weeks after CY administration, these phenomena declined. In conclusion, the present study provided a new insight into the differential effects of CY on various populations and subpopulations of immune cells in the rat spleen.

This study was undertaken to investigate the effects of cyclophosphamide (CY) on dendritic cells (DCs) and ED2 positive tissue macrophages in adult rat lymphoid and non-lymphoid organs. A single dose of CY (150 mg/kg) was administered to Sprague-Dawley rats by intraperitoneal injection. After the rats were sacrificed in groups of three at 1 day, 3 days, 1 week, 2 weeks and 1 month, the tongue, heart, urinary bladder, thymus, spleen and cervical lymph nodes were removed. The immunocytochemical characterization of the cells was carried out using the monoclonal antibodies OX6, OX62 and ED2 in cryostat-cut sections. CY elicited a decrease in number of intraepithelial and interstitial DCs in urinary bladder and in number of interdigitating DCs in all the lymphoid organs examined in this study, whereas CY did not cause any alteration in the number and distribution pattern of dendritic cells in tongue and hearts. CY increased the size and number of tissue macrophages in all the organs examined in this study. Most of these features began to appear from the first day and reached the maximun on the third and seventh day, but two weeks after CY administration, these phenomena declined. In conclusion, CY has differential effects on the rat DCs and macrophages and also on the subpopulations of DC according to the location and the functional state.
