OBJECTIVE: The involvement of IGF system in hyperandrogenism and abnormal follicular development is controversial. This study is to assess whether IGF system contribute to it in the women with polycystic ovary(PCO). METHODS: Baseline serum levels of luteinizing hormone (LH), follicle stimulating hormone (FSH), estradiol (E2), testosterone (T), androstenedione (ADD), prolactin, thyroid stimulating hormone (TSH), free insulin-like growth factor(IGF)-I, free IGF-II, insulin-like growth factor binding protein(IGFBP)-1, and IGFBP-3 were measured in twelve healthy regularly cycling volunteers and forty-two women with PCO then, the changes of baseline serum levels were evaluated after laparoscopic ovarian electrocauterization in nine PCO patients. In addition, the expression pattern of IGF-I and IGF-II was examined in the ovary of control and PCO group. RESULTS: Baseline levels of LH, ADD, free IGF-II, and IGFBP-3 were significantly higher in PCO group. However, there were no significant differences in the levels of free IGF-I and IGFBP-1, although free IGF-I showed decreasing tendency in PCO group. And there was a significant positive correlation between the LH and free IGF-II level in the PCO(P=0.011, r2=0.3899), but not in the control. After ovarian electrocauterization, LH, T, and ADD levels decreased, and free IGF-I and IGFBP-3 level increased. While free IGF-II and IGFBP-1 level showed no significant changes. In the ovary, expression of both IGFs showed similar pattern in normal and PCO ovaries. CONCLUSIONS: The elevated IGFBP-3 level may alter the bioavailability of IGF(s) in the PCO. The change in IGF-I level and resumption of ovulation after electrocauterization, suggest a possible role of IGF system in the impairment of follicular development in the PCO.

Normal and abnormal follicular growth and steroidogenesis depend on gonadotropins as well as intraovarian peptides, which may mediate or potentiate gonadotropin action. Inhibin also affect follicular development and steroidogenesis and may play a role in dominant follicle selection and follicular atresia. Therefore, we studied the differences of serum inhibin, gonadotropin and androgen levels in the women with only the ultrasound findings and no disorder, and polycystic ovary (PCO) with ovulatory disturbance. We prospectively analysed forty-three women with PCO. The diagnosis of PCO was based on typical appearance of the ovaries on TVS. Twelve women with regular menstrual cycle and normal ovarian morphology were selected as control. Basal levels of inhibin, luteinizing hormone(LH), follicle stimulating hormone(FSH), estradiol(E2), testosterone(T), androstenedione(ADD), dehydroepiandrosterone-sulfate(DS), prolactin and TSH in serum were determined. There were significant differences in basal LH levels and LH/FSH ratio between the control and the women with PCO. The basal levels of inhibin and E2 in the oligo-amenorrheic PCO (N=34) were significantly higher than those in the control. There was higher negative correlation between the inhibin and T levels in the oligo-amenorrheic PCO, but, not in the regular cycling PCO. Also, there was higher positive correlation between the LH and T levels in the oligo-amenorrheic PCO, but not in the regular cycling PCO. These data presume that the initial event of PCO is elevated pituitary LH secretion. Elevated levels of LH may down-regulate LH receptors on granulosa cells and also cause hypertrophy of the thecal layer. High level of androgen secreted by the hypertrophied thermal layer may stimulate inhibin secretion from granulosa cells and can be converted to estrogen by extraovarian tissues and could serve to augment pituitary sensitivity to GnRH with a resultant secretion of more LH follicular development and dominant follicle selection resulted in ovulatory disturbance.

Dermatophytes infect the human hair, skin, nail and cause the dermatophytosis. The extracellular and intracellular proteinases of the dermatophytes commonly occur in the genus Trichophyton like T. rubrum, T. mentagrophytes, and T. granulosum. These enzymes play a prominent role in growth, multiplication and infection of the host tissue. Extracellular proteinases have been purified from the species of Trichophyton and Microsporum. We purified the proteinase partially from the culture filtrate of the Trichophyton tonsurans through Mono-Q and Superose 12 column and investigated its biochemical and enzymatic characters. The molecular size of the proteinase was estimated to be 41 kDa by SDS-PAGE. And pI was 3.2. The optimal temperature and pH for an enzymatic activity were 27C and 7.5, respectively. The purified porteinase degraded the keratin, bovine serum albumin, hemoglobin. The serine proteinase inhibitor like PMSF and DFP inhibited the proteolytic activity of the purified enzyme whereas the cysteinase inhibitor did not. These results demonstrated that the purified proteinase is a serine proteinase and can contribute the tissue invasion.

The global emergence and spread of multidrug resistant bacterial infections in communities and hospitals has become an important issue in public health. The resistance rate of gram-positive cocci to vancomycin and the resistance rate of several gram-negative bacilli against cefotaxime and carbapenem have been continuously increasing. Surveillance of antimicrobial resistance is essential for providing information on the magnitude of and trend in multidrug resistance. Therefore, beginning 2011, more robust and effective management is to be legally required for six multidrug-resistant bacteria that have been linked to healthcare-related infections: vancomycin-resistant Staphylococcus aureus (VRSA), vancomycin-resistant enterococci (VRE), methicillin-resistant S. aureus (MRSA), multidrug-resistant Pseudomonas aeruginosa (MRPA), multidrug-resistant Acinetobacter baumannii (MRAB), and carbapenem-resistant Enterobactericeae (CRE). We have also performed laboratory-based sentinel surveillance for VRSA/VISA since 2002 and carbapenemase-producing Enterobacteriaceae since November, 2010. This article reviews the national surveillance programs, and molecular epidemiology of multidrug-resistant bacteria.

An open trial was carried out to investigate the efficacy and tolerance of isosorbide 5-mononitrate(Elantan(R)) in 30 patients diagnosed as angina pectoris at Pusan national university hospital. Drugs were given 20mg two times daily for 2 to 3 weeks and the results were assessed in terms of effects on anginal pain and untoward side effects experienced during administration of medication. Treament resulted in an overall improvement in 25 patients(83.4%), complete abolition of anginal attacks in 17 patients(56.7%) and reduction in frequency of attacks in 8 patients(26.7%). So called "Nitrated headache" was observed in 5 patients(16.6%) but improved with proceeding of administration in 3 patients. This trial indicates that isosorbide 5-mononitrate should be efficacious as well as tolerated in patients with coronary heart disease.

BACKGROUND: Dermatophytoses are infections of keratinized tissues, that is, the epidermis, hair and nails, caused by a group of specialized fungi, the dermatophytes. Laboratory diagnoses of dermatophytes such as Tricophyton, Microsporum and Epidermophyton are made by microscopic examination and in vitro culture but they are either time consuming of lacking specificity. OBJECTIVE: In order to develop and apply more rapid and precise diagnostic tests for fungal pathogens to facilitate the improved identification of dermatophytes, we investigated random amplified polymorphism DNA for classification and identification of dermatophytes. METHODS: Amplification reactions were performed in volumes of 5011 containing 10mM Tris-HCl(pH 8.3), 50mM KCl, 1.5mM MgCl2, 0.01% (w/v), gelatin, 200mM dNTP mixture, 50pM primer, Taq polymerase (0.025 units/ microliter), DNA 0.001 microgram/microliter. The optimal condition to. PCR was 2 cycles (denaturing 94 degrees C 2min, annealing 33 degrees C 2min, extension 72 degrees C 4min), 40 cycles, and extension (72 degrees C 10min). RESULTS: RAPD showed interspecies polymorphism in but it had identical patterns in intraspecies. CONCLUSION: It was confirmed that RAPD PCR analysis with optimal conditions is a fast, economical and reproducible method for identification and classification of dermatophytes isolates.

PURPOSE: The prevalence of type 2 diabetes mellitus (T2DM) and obesity are currently increasing. Accordingly, the concept of "preventing diabetes" in high-risk groups has become more important in diabetic care, but the use of glycated hemoglobin (HbA1c) as a measure has limitations in this field. The aim of this study was to investigate the utility of 1,5-anhydroglucitol (1,5-AG) in assessing prediabetes status in obese children. METHODS: The medical records of 74 subjects aged 6-19 years (of which 27 were overweight/obese and 47 had diabetes) who had 1,5-AG data were reviewed retrospectively. We compared 1,5-AG with HbA1c using the Pearson correlation test to assess the clinical utility of 1,5-AG. RESULTS: 1,5-AG levels were higher (31.1+/-10.1 microg/mL vs. 7.4+/-7.3 microg/mL) and HbA1c levels were lower (5.5%+/-0.3% vs. 8.9%+/-2.7%) in the overweight/obese group than in the diabetics group. The range of 1,5-AG levels in obese children was wide (16.8-59.3 microg/mL), and did not have significance with HbA1c. A negative correlation between 1,5-AG and HbA1c was significant in the entire subject (r=-0.822, P<0.001), and also in the HbA1c range of 5.5% to 8% (r=-0.736, P<0.001). CONCLUSION: 1,5-AG is a valuable index in the HbA1c range of 5.5%-8% and it might be considered an early glycemic control index in insulin-resistant obese children with an HbA1c level above 5.5%. Moreover, the 1,5-AG level assessment should be presented as a supplementary tool for better compliance, as well as being an improvement in diabetes management for the short-term glucose control in relatively well-controlled diabetes patients with an HbA1c level below 8%.

PURPOSE: This study aimed to examine the effects of cyclooxgenase-2 inhibitors on patients with nocturia, whose symptoms persisted after the use of first-line drug therapy, such as alpha blockers and/or anticholinergics. MATERIALS AND METHODS: Thirty-three patients whose symptoms persisted after more than three months of first-line drug therapy were chosen to receive additional COX-2 inhibitors or antidiuretic hormones orally. Seven patients (group 1) were given 80mg of zaltoprofen at night, while 15 (group 2) were given 100mg of nimesulide at night. Desmopressin acetate (0.2mg) was administered at night to 11 patients (group 3) as a control group. Median follow up was 35 days (range, 28~90 days). RESULTS: In 25 patients (75.8%), the severity of nocturia was reduced. The median decline of nocturia in the COX-2 inhibitor groups (groups 1 and 2) was once, and it was statistically significant (p<0.001), while the median decline in each of these groups was twice (p=0.026) and once (p=0.002), respectively. The reduction of nocturia in the control group was once (p=0.011). The differences in reduction between the COX-2 inhibitor group and the control group were not statistically significant (p=0.418). CONCLUSIONS: The effects of the COX-2 inhibitors were not significantly different from those of desmopressin. Combination therapy with COX-2 inhibitors can effectively reduce nocturia in patients with refractory nocturia, following first-line drug therapy.

PURPOSE: Each ethnic group has a unique life style, including diets. Life style affects bowel movement. The aim of this study is to describe the results of colon transit time (CTT) tests in Korean children who had chronic functional constipation based on highly refined data. METHODS: One hundred ninety (86 males) out of 415 children who performed a CTT test under the diagnosis of chronic constipation according to Rome III criteria at Konkuk University Medical Center from January 2006 through March 2015 were enrolled in this study. Two hundreds twenty-five children were excluded on the basis of CTT test result, defecation diary, and clinical setting. Shapiro-Wilk and Mann-Whitney U, and chi-square tests were used for statistical analysis. RESULTS: The median value and interquartile range (IQR) of CTT was 54 (37.5) hours in Encopresis group, and those in non-encopresis group was 40.2 (27.9) hours (p<0.001). The frequency of subtype between non-encopresis group and encopresis was statistically significant (p=0.002). The non-encopresis group (n=154, 81.1%) was divided into normal transit subgroup (n=84, 54.5%; median value and IQR of CTT=26.4 [9.6] hours), outlet obstruction subgroup (n=18, 11.7%; 62.4 [15.6] hours), and slow transit subgroup (n=52, 33.8%; 54.6 [21.0] hours]. The encopresis group (n=36, 18.9%) was divided into normal transit subgroup (n=8, 22.2%; median value and IQR of CTT=32.4 [9.9] hours), outlet obstruction subgroup (n=8, 22.2%; 67.8 [34.8] hours), and slow transit subgroup (n=20, 55.6%; 59.4 [62.7]hours). CONCLUSION: This study provided the basic pattern and value of the CTT test in Korean children with chronic constipation.
