BACKGROUND: Combination of metformin to reduce the fasting plasma glucose level and an α-glucosidase inhibitor to decrease the postprandial glucose level is expected to generate a complementary effect. We compared the efficacy and safety of a fixed-dose combination of voglibose plus metformin (vogmet) with metformin monotherapy in drug-naïve newly-diagnosed type 2 diabetes mellitus. METHODS: A total of 187 eligible patients aged 20 to 70 years, with a glycosylated hemoglobin (HbA1c) level of 7.0% to 11.0%, were randomized into either vogmet or metformin treatments for 24 weeks. A change in the HbA1c level from baseline was measured at week 24. RESULTS: The reduction in the levels of HbA1c was −1.62%±0.07% in the vogmet group and −1.31%±0.07% in the metformin group (P=0.003), and significantly more vogmet-treated patients achieved the target HbA1c levels of <6.5% (P=0.002) or <7% (P=0.039). Glycemic variability was also significantly improved with vogmet treatment, estimated by M-values (P=0.004). Gastrointestinal adverse events and hypoglycemia (%) were numerically lower in the vogmet-treated group. Moreover, a significant weight loss was observed with vogmet treatment compared with metformin (−1.63 kg vs. −0.86 kg, P=0.039). CONCLUSION: Vogmet is a safe antihyperglycemic agent that controls blood glucose level effectively, yields weight loss, and is superior to metformin in terms of various key glycemic parameters without increasing the risk of hypoglycemia.

Benzylideneacetophenone derivative (1E)-1-(4-hydroxy-3-methoxyphenyl) hept-1-en-3-one (JC3) elicited cytotoxic effects on MDA-MB 231 human breast cancer cells-radiation resistant cells (MDA-MB 231-RR), in a dose-dependent manner, with an IC₅₀ value of 6 μM JC3. JC3-mediated apoptosis was confirmed by increase in sub-G1 cell population. JC3 disrupted the mitochondrial membrane potential, and reduced expression of anti-apoptotic B cell lymphoma-2 protein, whereas it increased expression of pro-apoptotic Bcl-2-associated X protein, leading to the cleavage of caspase-9, caspase-3 and poly (ADP-ribose) polymerase. In addition, JC3 activated mitogen-activated protein kinases, and specific inhibitors of these kinases abrogated the JC3-induced increase in apoptotic bodies. JC3 increased the level of intracellular reactive oxygen species and enhanced oxidative macromolecular damage via lipid peroxidation, protein carbonylation, and DNA strand breakage. Considering these findings, JC3 is an effective therapy against radiation-resistant human breast cancer cells.

PURPOSE: We designed a pig to canine liver xenotransplantation model to study the diverse immunologic and hemodynamic consequences that follow xenotransplantation and hyperacute rejection. METHODS: The animals were divided into two groups: the cobra venom factor and Gadolinium chloride treatment group (CVF+Gd group) (3 cases) and the control group (3 cases). The donor pig's whole liver was harvested, and then the harvested pig's whole liver was transplanted into a dog after the dog underwent left hepatectomy. After reperfusion of the graft, blood samples were taken 20, 40 and 60 minutes after reperfusion, and the liver, lung and kidney tissues were taken 1 hour after reperfusion. RESULTS: In the control group, the grafts showed a patchy hypoperfused liver surface and it felt rubbery solid compared to the CVF+Gd group. The serum total protein, albumin, fibrinogen and platelets decreased abruptly and there were no significant differences between the two groups. The serum PT, PTT and FDP were increased in both groups and the CVF+Gd group showed a more obtuse slope than the control group. We could not find any intravascular pathologic changes on the microscopic findings of the graft. Only scant intravascular fibrin deposition was found. Hepatocellular vacuolization and sinusoidal dilatation were also found. There were patches of necrosis without any zonal distribution, intrasinusoidal neutrophil sequestration and interstitial hemorrhage. These findings were milder in the CVF+Gd group. CONCLUSION: The pig to canine partial auxiliary liver xenotransplantation model is feasible and it is a good model before starting to perform pig to primate liver xenotransplantation. In the CVF+Gd group, pathologic findings like patch hepatocyte necrosis etc. were less severe. As there were no corresponding vascular pathologic findings, these findings are not the direct effect of CVF and gadolinium treatment, and so other factors like Ischemia- reperfusion injury should be considered.

OBJECTIVE: This study evaluated the relationship between injury occurrence and workplace organization in small-sized, manufacturing factories in Korea. METHODS: Using data from the 2004 Occupational Safety and Health Survey in Korea, this study compared workplace organizational factors (general characteristics, employee characteristics and health and safety characteristics) with injury occurrence of 1,866 small-sized, manufacturing factories (65,921 population factories after weighting). General characteristics of factories comprised location, type and classification of industry. Employee characteristics comprised proportion of manual workers and female workers, average working hours per week and shiftwork. Health and safety characteristics comprised type of safety and health manager, committee for occupational safety and health, labor union, health and safety regulation, monthly health and safety training time, score of health and safety activity and score of safety culture. RESULTS: The following characteristics of injury-occurrence in small-sized, manufacturing factories were determined by multivariate analysis. In terms of general characteristics, the risk of injury-occurrence was higher in Jeolla area than Gyeongin area in outside associate than other enterprises and in coke, refined petroleum products and nuclear fuel, wood and products of wood, food products and beverages and fabricated metal products, except machinery and furniture industries than television and communication equipment and apparatus industries. In terms of employee characteristics, injury-occurrence significantly increased in factories with greater proportion of manual worker and with a higher rate of working hours per week. But significantly decreased in factories with a higher proportion of female workers. In terms of health and safety characteristics, injury-occurrence significantly increased in factories with a self-appointed safety manager, with unorganized union, with a more active committee for occupational safety and health, with unimplemented health and safety regulations, with longer monthly safety and health training time, and with a lower score of safety culture. CONCLUSIONS: This study demonstrated that several factors of workplace organization were significantly related with injury-occurrence in factories. These findings are supposed to raise the need for making efforts in workplace organization to improve injury prevention.

Traditionally, early appendectomy has been the cornerstone of therapy for acute appendicitis. However, once appendiceal perforation and abscess formation occurs, the optimal means of treatment and the timing of operation is controversial. Recently, it was reported that radiologically guided percutaneous abscess drainage and antibiotic therapy, as an initial nonoperative management, was effective and safe. Recent experience with endoscopic transmural drainage of pancreatic pseudocysts or even pancreatic abscesses prompted us to use the similar technique for the primary treatment of peri-appendiceal abscess. We report a case of peri-appendiceal abscess complicating acute appendicitis which was successfully treated by colonoscopic transmural internal drainage.

OBJECTIVE: To understand the difference of defecation physiology between postpartum and postoperative women. METHODS: Between July 1998 to April 1999, we performed defecogram and pudendal nerve motor latency to 31 women, who were 8 postoperative women, 9 post cesarean-section state women, and 14 normal vaginal delivery-state women. RESULTS: According to the defecogram results, only squeezing angles of the anorectal angle were significantly increased(96.0 vs 72.3, 74.9 degree) in normal vaginal delivery-state women compared to post cesarean-section state and postoperative women, but rest and evacuation angles were not. And to pudendal nerve latency, there were no statistically significant difference. CONCLUSION: We concluded that the pudendal plexus was damaged during labor, therefore its ability to control puborectalis muscle was damaged. So, the anorectal angles of squeezing of postpartum women were significantly increased, compared to those of post cesarean section women or postoperative women.

PURPOSE: We compared the outcome of transurethral resection of the prostate (TURP) with that of transurethral needle ablation(TUNA) of the prostate in patient with BPH. MATERIALS AND METHODS: From May 1996 to April 1997, 21 patients were treated with TURP and 25 with TUNA. In TURP group, the mean age was 67.2 years and mean prostatic volume was 52.7ml. In TUNA group, the mean age was 67.2 years and mean prostatic volume was 32.1ml. Assessment parameters were International Prostate Symptom Score(1-PSS), quality of life question, uroflowmetry and complications. Post-treatment morbidity was noted if the patients experienced erectile dysfunction, retrograde ejaculation or urinary incontinence. Patients were examined at 3 months from the day of treatment. RESULTS: At 3 months, the maximum flow rate improved from the mean of 10.2+/- 3.2m1/sec to 20.5+/-10.7m1/sec for the TURP group and 9.3+/-1.9m1/sec to 12.5+/-4.3 for the TUNA group. 1-PSS improved from the mean 22.0+/-7.6 to 6.4+/-4.6 for the TURP group and 21.2+/-6.6 to 13.1+/-6.8 for the TUNA group. Quality of life improved from the mean 3.8)1.6 to 1.3+/-1.0 for the TURP group and 4.3+/-0.9 to 2.9+/-1.1 for the TUNA group. Erectile dysfunction was reported in 43% (9/21) of TURP and 5%(1/20) of TUNA. Retrograde ejaculation was reported in 57%(12/21) and urinary incontinence was in 5%(1/21) of TURP. Retrograde ejaculation and urinary incontinence was not reported with TUNA. The mean operation time, hospital stay and a catheterization time in the TUNA group were 45.4min, 1.2days, 4.4days in comparison with 58.7min, 7.0days, 3.6days in the TURP group. CONCLUSIONS: After TURP and TUNA, there was significant improvement in all clinical parameters. But TURP was more effective in improving maximum flow rate, 1-PSS and quality of life. TUNA, however, produced minimal morbidity with no serious complication. With acceptable low morbidity, TUNA appears to be a safe and effective procedure in the treatment of BPH.

Intermittent exotropia occurs commonly in Korea and its clinical characteristics are relatively well known. We analyzed the clinical characteristics of intermittent exotropia and studied the relationship among them. We examined 229 patients(92 males and 137 females( who first visited three strabismic clinics. The age of onset, frequency, family history and symptoms of intermittent exotropia were examined. The angle and type of deviation were studied and sensory tests were done. The mean age of onset was 32.4 months and frequency ws 39.1% and family history was 8.7%. Photophobia was the most common symptom of intermittent exotropia. The distant angle of deviation was 26.7 prism diopters in average and the near angle was 25.3 prism diopters in average. The most common type of intermittent exotropia was basic type. followed by simulated divergence excess type, convergence insufficiency type, and divergence excess type. In statistical study, there was no significant relationship among clinical characteristics of intermittent exotroia.

PURPOSE: The aim of this study was to assess the involvement of several organs patients with Marfan syndrome in Korea. Also the clinical features in childhood patients with Marfan syndrome were assessed. METHODS: Thirty-eight cases of Marfan syndrome were enrolled in this study. Clinical evaluations of the musculoskeletal, cardiovascular and occular system were performed in all cases. RESULTS: The musculoskeletal system was involved in 32 cases (84.2%) and occular system in 24 cases (63.1%). Cardiovascular abnormalities were found in 19 cases (50.0%) at initial evaluation. Family history was involved in 21 cases (55.2%). Ectopia lentis was found in 17 cases (70.8%). Severe myopia and iris abnormalities were also present in 14 cases (58.2%). The ascending aorta was dilated in 13 cases (34.2%). Emergency operation was performed in 3 cases (7.9%) because of a dissecting aorta. Mitral regurgitation and prolapse were found in 29 cases (76.4%) and other valve insufficiency was accompainied in 5 cases (13.1%). Of the 38 cases, 29 patients (79.3%) were less than 15 years of age and their major manifestations were occular problems in 23 cases (79.3%), and family history in 17 cases (58.6%). In one infant, severe heart failure was the predominant clinical feature. CONCLUSION: The clinical features of Korean patients with Marfan syndrome were summarized in this report. Heart failure was the main manifestaton in infantile Marfan syndrome. Early treatment with beta-blocker and valvular replacement can prevent fatality, i.e. aortic dissection, in this disease, concern and management should be advocated in the early detection of Marfan syndrome.
