Among various vascular interventional procedures, there are some procedures of vascular recanalization often encountered by primary physicians in clinical practice. These are percutaneous transluminal angioplasty (PTA) and stent application in the lower extremity ishemia, catheter-directed thrombolysis with PTA, stenting for iliofemoral deep vein thrombosis, and interventional management of arteriovenous fistula and graft for hemodialysis access. PTA and stent are safe and effective treatment for iliac arterial stenosis and occlusion with a good long-term patency rate. Long-term effectiveness of femoropopliteal stent is yet to be determined. Catheter-directed thrombolysis is a new emerging vascular intervention for acute iliofemoral deep vein thrombosis. May-Thurner syndrome can be effectively treated with thrombolysis in the iliofemoral vein followed by PTA ad stenting for the left iliac vein stenosis or occlusion. For the failing arteriovenous fistula or grafts in patients with hemodialysis, interventional radiologists can play an important role for the maintenance of the patency by percutaneous thrombolysis and balloon dilatation. It will be very helpful for the primary physicians to understand the role of the interventional radiologists and the indications, techniques, and results of those vascular interventional procedures often encountered in daily practice.

OBJECTIVE: To assess the potential clinical utility of in-vivo 31P magnetic resonance spectroscopy (MRS) in patients with various malignant and benign breast lesions. MATERIALS AND METHODS: Seventeen patients with untreated primary malignant breast lesions (group I), eight patients with untreated benign breast lesions (group II) and seven normal breasts (group III) were included in this study. In-vivo 31P MRS was performed using a 1.5 Tesla MR scanner. Because of the characteristics of the coil, the volume of the tumor had to exceed 12 cc (3 x 2 x 2 cm), with a superoinferior diameter at least 3 cm. Mean and standard deviations of each metabolite were calculated and metabolite ratios, such as PME/PCr, PDE/PCr, T-ATP/PCr and PCr/T-ATP were calculated and statistically analyzed. RESULTS: Significant differences in PME were noted between groups I and III (p=0.0213), and between groups II and III (p=0.0213). The metabolite ratios which showed significant differences were PME/PCr (between groups II and III) (p=0.0201), PDE/PCr (between groups I and III, and between groups II and III) (p=0.0172), T-ATP/PCr (between groups II and III) (p=0.0287), and PCr/T-ATP (between groups II and III) (p=0.0287). There were no significant parameters between groups I and II. CONCLUSION: In-vivo 31P MRS is not helpful for establishing a differential diagnosis between benign and malignant breast lesions, at least with relatively large lesions greater than 3 cm in one or more dimensions.

OBJECTIVE: Pelviscopic surgery has been used in the treatment of some gynecologic disease. And now, it is applied in almost all cases of gynecologic disease. This study is performed to evaluate the clinical advantages of pelviscopic surgery. Mehtods: From March, 1997 to February 1999, total 310 cases were received laparoscopic surgery on dept. OBGY of Seonam University hospital and Chosun University hospital. We reviewed the chart and analyzed these cases about age, parity, clinical indication, operation type, duration of hospitalization, operation time and complication. RESULTS: The results of this study were summarized as follows : 1. The mean age of patients was 32.1 years old with ranges between 15 and 54 years old. 2. The mean parity of the patients was 1.33. 3. The common indications were ectopic pregnancy (33.5%), ovarian cyst (28.4%) and uterine myoma (16.5%). 4. The frequent types of surgery were salpingectomy (23.2%), adnexectomy (22.6%) and laparoscopy assisted vaginal hysterectomy (LAVH) (13.9%). 5. The operation time was variable according to the types of operation and difficulty. 6. The mean duration of hospitalization was 4.17 days. 7. The most frequent complication was hemorrhage at the trocar site. CONCLUSION: Pelviscopic surgery is useful and recommended for the treatment of gynecologic disease, because this is safe and has many advantages. So, we expect the number and indication of pelviscopic surgery will be increased in future.

Eighty three rickets could be diagnosed at our department during eight years from August of 1969 to July of 1977. Among them fourteen children, whose radiographs and clinical description were precise with well-documented follow-up study of more than one year, were subjected to this analysis. Evaluation of the healing and correction of the lower leg deformity in these rachitic children obtained the following results. 1. Among fourteen rachitic children, thirteen patients (26 legs) showed varus and one patient (2 legs) showed valgus deformity. 2. Mean mechanical tibio-femoral angle showed shift from the initial 16.1°±5.3° to 5.5°+4.0° at final visit, which indicated the gradual correction of the deformity with the advance of the ages of children. The follow-up study after three years in this series showed that the correction became almost complete. 3. At the epiphyseo-metaphyseal region of the distal femur, the initial angle showed two distinct trends of change. The initial varus angle more than 7 or 8 showed the decrease at the later follow-up study, while the initial angle less than 7 or 8 showed the increase. 4. The epiphyseo-metaphyseal region of the proximal tibia showed the minimum change of angle. Mean angle of deviation from the vertical line was 3.7°±2.9° at first visit and 2.6°± 2.4°at final visit. The least degree of varus and the trend toward valgus observed in this region may refiect its compensatory activity against the varus deformity of the leg as a whole. 5. The epiphyseo-metaphyseal region of the distal tibia showed the maximum degree of varus at both initial and final check although the greatest degree of correction was attained. The initial mean varus angle of 23.9°±9.2° became 12.9°±7.1° at final visit. 6. The results of this study have shown that the correct evaluation of the rcchitic leg deformity is possible with measurement of the mechanical tibio-femoral angle and that the deviation angle of each epipyseo-metaphyseal region is preferable.

To evaluate the influence of tourniquet ischemia and hyperthermia on the radiation effect of skin, theexperimental study was undertaken using a total of 344 mice. A single dose of irradiation from 2000 rads to 8000rads was delivered on skin of mouse tail after hyperthermia of 40degrees(C) to 42degrees(C) with or withouttourniquet application in various subgroups. The resuls are summarized as follows; 1. Tourniquet ischemia duringirradiation caused radioprotective effect. 2. Hyperthermia before irradiation induced radiosensitizing effect,which was increased with temperature elevation of hyperthermia. 3. In combination of tourniquet ischemia andhyperthermia, evident radiosensitizing effect waas noticed. This enhancing effect on irradiation was greater thanthe effect i hyperthermia only. It could be suggested that the combination of tourniquet application andhyperthermia might be intorduced in clinical radiotherapy after trail of clinical experiments on applicable typeand sutiable location of tumors.

The orchid symbiotic fungi were isolated from the roots of Korean native orchid (Cymbidium goeringii) collected and Chinese orchid (C. sinense) obtained from greenhouses. They were identified as a species of Rhizoctonia, based on the sequences of 18r rDNA, the microscopic observations of mycelia, and the symbiotic relationships with commercial orchids. The isolate collected from Chinese orchids was revealed to be a species of Ceratobasidium endophytica, and to be different from the other isolates at the thickness of the mycelia stained in the root cells of Korean native orchids. The other isolates collected from the Korean native orchids were considered to be a species of Tulsanella repens (anamorphic: Epulorhiza repens) or its related one. The physiologic or microscopic variations were oftenly observed among them, but the tendency of grouping these in the 18s rDNA sequences were observed to be consistent with those of the localities collected. The further taxonomical segregating for Korean symbiotic fungi was not made because the information concerned were limited in this moment, but was recognized as based on the sequences of 18s DNA.

The incidence of ectopic pregnancy is apparently increasing in recent years. In order to gain greater insight into the diagnosis and management of ectopic pregnancies, this study was undertaken on 100 patients with ectopic pregnancy(admitted via ER) who were operated and confirmed by histopathological study at the department of Obstetrics and Gynecology of Hallym University(Kangdong Sacred Heart Hospital) from January, 1996 to June, 1997. The results were as follows; 1. The hospital incidence of ectopic pregnancy was 1 in 11.6 deliveries(168/1954). 2. The most frequent age group was in 25-34 years of ages(58%). 3. Nullipara was 32 cases(32%) and number of cases who had 1, 2 and 3 deliveries were 35(35%), 31(31%) and 2(2%) respectively. 4. The most frequent number of pregnancy was second times(24%) and 65% of cases have been experienced artificial abortion. 5. In the past history, of possible predisposing factors, 65% had at least one abortion, 17% ectopic pregnancy, 17% cesarean section and 13% had previous laparoscopic tubal sterilization, but 19% showed no special distinct. 6. The main clinical symptoms are 96% in lower abdominal pain, 95% in amenorrhea and 65% in vaginal spotting and bleeding. 7. The most frequent interval between LMP and onset of symptoms was 6-8 weeks(49%). 8. Urine hcG test was positive in 94.9% and culdocentesis was positive in 94.3%. 9. In initial hemoglobin level, more than 11.0g% was 55%, however less than 10.0g% was 20%. 10. In initial systolic blood pressure at hospital, most of them were under normal condition, however 30% were under 90mmHg. 11. The amount of intraabdominal hemorrhage under 500cc was 42%(highest rate), 25% under 500cc-1000cc(second rate) and 6 cases overed 200cc. 12. The site of ectopic pregnancy was 88% in fallopian tube, 9% in uterine conus, 2% in intraabdomen and 1% in cervix. 13. The most common surgical procedure was ipsilateral salpingectomy(82%), of which 22 cases were operated by laparoscopy. 14. There was no fatal case in 100 ectopic pregnancy.
