The authors analyzed 23 cases of shoulder arthrography performed at Busan National University Hospital and Inje Medical College Paik Hospital for about 2.5 years from March 1981 to Sept. 1983, both clinically and radiologically. The results obtained were as follows; 1. Of the 23 cases, 20 cases (87.0%) were male and 3 cases(13.0%) were female, and the most prevalent age group was second decade. 2. Right shoulder arthrography was performed in 16 cases (69.6%), and left in 7 cases (30.4%). 3. The number of cases which had had certain historyof trauma was 13(56.5%), and remainder of 10 cases (43.5%) had no history of trauma. 4. Frequent symptoms andsigns were pain in shoulder region in 16 cases (69.6%) and limitation of motion in 14 cases (60.9%). 5. On plainfilm findings, 18 cases(78.3%) were normal, and 5 cases (21.7%) were abnormal. 6. On shoulder arthrographicfindings, 16 cases (69.6%) were normal, and 7 cases (30.4%) were abnormal, Those abnormal cases were consisted of2 case (8.7%) of adhesive capsulitis, 2 cases (8.7%) of chronic shoulder dislocation, 1 case(4.3%) of rotator cuff tear, 1 case(4.3%) of loose bodies in joint cavity, and 1 case(4.3%) of rupture of biceps tendon sheath. 7. Among routine views of shoulder arthrography of normal cases, the external rotation view revealed axillary recess &biceps tendon more distinctly, and the internal rotaion view revealed subscapular bursa more clearly.

PURPOSE: To investigate the growth inhibitory effects, and the underlying mechanism of human colon cancer cell (HT-29) death, induced by a new synthetic bile acid derivative (HS-1200). MATERIALS AND METHODS: Human colon cancer cells (HT-29), in exponential growth phase, were treated with various concentrations of a new synthetic bile acid derivative (HS-1200). The growth inhibitory effects on HT-29 cells were examined using a trypan blue exclusion assay. The extent of apoptosis was determined using agarose gel electrophoresis, TUNEL assays and Hoechst staining. The apoptotic cell death was also confirmed by Western blotting of PARP, caspase-3 and DNA fragmentation factor (DFF) analysis. To investigate the involvement of mitochondria, we employed immunofluorescent staining of cytochrome c and mitochondrial membrane potential analyses. RESULTS: The dose required for the half maximal inhibition (IC50) of the HT-29 cell growth was 100~150 micro M of HS-1200. Several changes, associated with the apoptosis of the HT-29 cells, were reveal by the agarose gel eletrophoresis, TUNEL assays and Hoechst staining, following their treatment with 100 micro M of HS-1200. HS-1200 treatment also induced caspase-3, PARP and DFF degradations, and the western blotting showed the processed caspase-3 p20, PARP p85 and DFF p30 and p11 cleaved products. Mitochondrial events were also demonstrated. The cytochrome c staining indicated that cytochrome c had been released from the mitochondria in the HS-1200 treated cells. The mitochondrial membrane potential (deltaxm) was also prominently decreased in the HS-1200 treated cells. CONCLUSION: These findings suggest that the HS-1200 - induced apoptosis of human colon cancer cells (HT-29) is mediated via caspase and mitochondrial pathways.

BACKGROUND: Detection of postoperative spinal cord level change can provide basic information about the spinal cord status, and electrophysiological studies regarding this point should be conducted in the future. METHODS: To determine the changes in the spinal cord level postoperatively and the possible associated factors, we prospectively studied 31 patients with scoliosis. All the patients underwent correction and posterior fusion using pedicle screws and rods between January 2008 and March 2009. The pre- and postoperative conus medullaris levels were determined by matching the axial magnetic resonance image to the sagittal scout image. The patients were divided according to the change in the postoperative conus medullaris level. The change group was defined as the patients who showed a change of more than one divided section in the vertebral column postoperatively, and the parameters of the change and non-change groups were compared. RESULTS: The mean pre- and postoperative Cobb's angle of the coronal curve was 76.80degrees +/- 17.19degrees and 33.23degrees +/- 14.39degrees, respectively. Eleven of 31 patients showed a lower conus medullaris level postoperatively. There were no differences in the pre- and postoperative magnitude of the coronal curve, lordosis and kyphosis between the groups. However, the postoperative degrees of correction of the coronal curve and lumbar lordosis were higher in the change group. There were also differences in the disease entities between the groups. A higher percentage of patients with Duchene muscular dystrophy had a change in level compared to that of the patients with cerebral palsy (83.3% vs. 45.5%, respectively). CONCLUSIONS: The conus medullaris level changed postoperatively in the patients with severe scoliosis. Overall, the postoperative degree of correction of the coronal curve was higher in the change group than that in the non-change group. The degrees of correction of the coronal curve and lumbar lordosis were related to the spinal cord level change after scoliosis correction.

BACKGROUND: Sympathetic blocking agent, esmolol (selective beta 1 blocker) or labetalol ( alpha and beta blocker) would prevent the hypertension and tachycardia from endotracheal intubation. We have carried out the study to see the effects of esmolol or labetalol on the blood pressure, heart rate, rate pressure product and plasma catecolamines during the endotracheal intubation. METHODS: Thirty-three ASA physical status 1 or 2 adult patients were allocated into three groups; Group I:control (n=10), Group II:esmolol (n=11) and Group III: labetalol (n=12). In Group I, 2 ml of normal saline, in Group II, 1 mg/kg of esmolol, and in Group III, 0.2 mg/kg of labetalol were given 3, 2 and 4 minutes before endotracheal intubation. Blood pressure and heart rate were measured after arrival at the operating room, before endotracheal intubation and after endotracheal intubation at 15, 60, 120, 180 and 300 seconds interval under the inhalation anesthesia (enflurane-N2O-O2). Rate-pressure product was calculated from the heart rate and systolic blood pressure (RPP = heart rate x systolic blood pressure). The plasma cathecolamines, dopamine, norepinephrine and epinephrine, were measured before intubation as a baseline value and 2 minute after intubation. RESULTS: Systolic blood pressure, rate-pressure product and heart rate were significantly lower in esmolol and labetalol groups than in control group after intubation ( p<0.05). Esmolol reduced the heart rate and the rate-pressure product than labetalol, but statistically there were no significance (P > 0.05). Plasma level of dopamine, norepinephrine and epinephrine showed higher values after intubation in all three groups ( p<0.05). But there were no difference among groups (P>0.05). The side effects of esmolol and labetalol did not appear at all. CONCLUSION: 1 mg/kg of esmolol given 2 min before intubation or 0.2 mg/kg of labetalol given 4 min before intubation reduce increasing of blood pressure and heart rate, caused by adnergic response following endotracheal intubation, significantly. The reason is that esmolol and labetalol do not decrease release of catecholamines but attenuate responses of elevated catecholamines following endotracheal intubation.

PURPOSE: We reviewed 604 cases of varicose veins managed in our hospital and the clinical feature and the results were analyzed between injection sclerotherapy and operative method. METHODS: Retrospective review of clinical records was done from January 1990 to June 1998. All of them were diagnosed as primary varicose veins of lower extremities. Sclerosing agents used were ethanolamine oleate, most commonly, hypertonic saline, sodium tetradecyl sulfate and sclerodex. Injections of the sclerosants were 1 to 5 times as the clinical courses. Then, elastic stocking was applied for 2 weeks. Operations were done under the spinal or general anesthesia and postoperatively remnant varicoses were managed by injection sclerotherapy. Student t-test was used in statistics. RESULTS: The distribution of age were 5th decade (36.8%), 6th decade (24.0%), 4th decade (22.2%) in order of frequency, and the mean age was 44.3 year and the male to female ratio was 1:4.0. The mean duration of illness was 12.6 year, and it was longer in female than male (13.2 vs. 8.7, p=0.02). The most common presumed predisposing factor was longstanding occupation (82% of all) and pregnancy was the 2nd in female (12.0%). Chief complaint was only cosmetic problem in 73% of patients and the others complained varicose induced symptoms and complications. Both lower extremities were involved in 41.9% and right leg was in 26.0%, left leg was in 32.1%. The locations of lesions were calf (41.4%), greater saphenous vein (34.6%), lesser saphenous vein (15.0%). Sclerotherapy was done in 48.0%, operation with sclerotherapy in 23.7%, operation only in 17.2%. The mean duration of illness in sclerotherapy group was significantly shorter than operation group (8.8 vs 14.7 year, p=0.0001). Operation methods were stab avulsion only (48.1%), greater saphenous vein stripping (37.3%) and perforator ligation (11.8%) and others. CONCLUSIONS: Injection sclerotherapy method is very effective and sufficient treatment modality in the management of lower extremity varicose vein with low recurrence and complication rate, especially in the early treated cases.

OBJECTIVE: It was to analyze two failed arterial embolization cases in the treatment for pseudoaneurysm followed by D&C. METHODS: Two failure cases out of eight cases were gained in the transarterial embolization treatment for eight years.(1. 1. 1992 - 12. 31. 1999) To search for the factors of failure, we went through obstetrical history and biopsy. RESULTS: Eight cases of transarterial embolization were performed to the treatment for pseudoaneurysm appeared after undergoing D&C. Six cases were successfully treated without complications. However, laparotomy was done due to the continuous bleeding in the other two cases. According to tissue biopsy, they showed the cervical pregnancy in one case and placenta accreta in the other. CONCLUSION: Transarterial embolization is proved to be more preferable to operate in the treatment of pseudoaneurysm than laparotomy, and transarterial embolization therapy failure rate is higher in case of existing remnant villi than not.

Familial Adenomatous Polyposis (FAP) is a rare and autosomal dominantly inherited disorder characterized by the development of hundreds to thousands of colorectal polyps. Korean Polyposis Registry was established in July, 1990 for early detection and management of the FAP patient. Recently, we have experienced in our institution a case of the FAP family kindred living in Jeju Island of Korea. Their relatives have been managed for the past 20 years and are listed in the Korean polyposis registry. Pathologic diagnosis of our proband was stage III (T3N1M0) rectal cancer with thousands of colonic polyps. Intrafamilial strife and psychologic distress was significant due to the late detection and progression to rectal cancer. Therefore, we reviewed our case of the FAP family with literature regarding the psychologic distress and the role of the regional registry.

This study aimed to determine the influence of pre-pregnancy body mass index on pregnancy outcomes in gestational diabetes mellitus (GDM), comparing underweight patients with GDM with normal weight patients with GDM. Maternal baseline characteristics, ultrasonographic results, and pregnancy and neonatal outcomes were reviewed in 946 women with GDM with singleton pregnancies. Underweight patients with GDM showed a benign course in most aspects during pregnancy, except for developing a higher risk of giving birth to small for gestational age neonates. Underweight women with GDM required less insulin treatment, had a higher rate of vaginal delivery, and had a lower rate of cesarean delivery. In addition, their neonates were more likely to have fetal abdominal circumference and estimated fetal weight below the 10th percentile both at the time of GDM diagnosis and before delivery. Notably, their risk for preeclampsia and macrosomia were lower. Collectively, our data suggest that underweight women with GDM may require a different approach in terms of diagnosis and management throughout their pregnancy.

Vasa previa is one of the most unusual and tragic accidents to fetus in obstetrics. This condition is not diagnosed easily because it is rare and unexpected. To improve the perinatal outcome, early detection by ultrasonography is very important during pregnancy. We present a case of vasa previa with velamentous insertion of cord with a brief review of the literatures concerned.

OBJECTIVE: The aim of the present study was to evaluate changes of vascular endothelial growth factor levels in maternal circulating blood during normal pregnancies and examine their relationship with maternal platelet counts. METHODS: The 33 subjects were selected from healthy normotensive women from the antenatal clinic at Korea University Medical Center, Guro Hospital. Blood samples for VEGF were taken at 7 to 8 weeks' gestation, 16 to 18 weeks' gestation, 24 to 26 weeks' gestation, 30 to 32 weeks' gestation, 37 to 41 weeks' gestation. Serum and plasma were extracted from all samples, and VEGF concentrations were measured in duplicates by competitive enzyme immunoassay. The 23 of them, the platelet counts were performed with an automated blood Coulter counter. RESULTS: Serum VEGF levels during normal pregnancies were mean 6.73 ng/mL at 7-8 weeks' gestation, 7.88 ng/mL at 16-18 weeks' gestation, 7.18 ng/mL at 24-26 weeks' gestation, 8.42 ng/mL at 30-32 weeks' gestation, 14.03 ng/mL at 37-41 weeks' gestation. Plasma VEGF levels were mean 5.50 ng/ mL at 7-8 weeks' gestation, 7.23 ng/mL at 16-18 weeks' gestation, 7.98 ng/mL at 24-26 weeks' gestation, 7.35 ng/mL at 30-32 weeks' gestation, 14.05 ng/mL at 37-41 weeks' gestation. The trends in the mean VEGF levels were similar between serum and plasma, with stable levels until 30 to 32 weeks' gestation, and then the levels were increased. There was no significant difference between serum VEGF levels and plasma VEGF levels (p=0.236) and no correlation between circulating VEGF levels and platelet counts. CONCLUSION: Our data suggests that platelets may not be the origin of elevated VEGF levels in normal pregnancies because there was no correlation between VEGF levels and platelet counts.
