OBJECTIVE: To analyze the clinical characteristics of obese infertile women. MATERIAL AND METHOD: Height, weight, body mass index, menstrual pattern, glucose, insulin, glucose / insulin ratio, dehydroepiandrosterone sulfate (DHEA-S), testosterone, free testosterone and plasminogen activator inhibitor (PAI-1) of 15 obese infertile women were tested. RESULTS: Of 15 obese infertile women, the number of diabetes mellitus, hyperinsulinemia, and insulin resistance was 2 (13%), 2 (13%), 2 (13%), respectively. The incidence of increased DHEA-S, testosterone, and free testosterone was 7 (47%), 1 (7%), 6 (40%), respectively. Notably, all patients showed increased PAI-1. CONCLUSIONS: Obesity is associated with infertility as well as many kinds of health problems. Obesity is closely related to insulin resistance and it also causes hyperandrogenism. Increased PAI-1 is one of the important causes of thrombophilia. Consequently, in the workup of obese infertile patient, many aspects of health problems should be considered.

BACKGROUND: Recent evidences suggest that anesthetic action within the spinal cord is important in suppressing somatic responses to painful stimuli. Intrathecal endothelin-1 (ET-1) is known to have antinociceptive effect. The purpose of this experiment was to determine whether intrathecal ET-1 may influence the minimum alveolar concentration (MAC) of isoflurane in rats and access the role of the spinal cord as the sites of anesthetic action in blocking somatic responsiveness. METHODS: In Sprague-Dawley rats fitted with an indwelling intrathecal catheter, we determined the MAC of isoflurane using a tail-clamp technique as a painful stimulus, combined with end-tidal anesthetic sampling. In experiment 1, the control MAC was determined and changes of control MAC were observed after intrathecal ET-1 (4x10-2 nmol, 4x10-3 nmol) administration. In experiment 2, we observed the effects of L or N type Ca++ channel blocker such as verapamil (50 g) or W-conotoxin (0.5 g) on the MAC after measurement of the control MAC. In experiment 3, after measurement of the control MAC, ET-1 (10-2 nmol) was administered intrathecally and the MAC was determined again. Next, intrathecal verapamil (50 g) or W-conotoxin (0.5 g) was injected. After that, the MAC was determined again. RESULTS: In experiment 1, ET-1 decreased the MAC of isoflurane and its effect was sustained over 2 hours. In experiment 2, the MAC, determined following administration of verapamil or W-conotoxin, was not different from that of the control. In experiment 3, the MAC was decreased after ET-1 administration and then increased following injection of verapamil or W-conotoxin. CONCLUSIONS: These results suggested that ET-1, in relation to calcium, might play an important role in determining the MAC of isoflurane in the spinal cord.

OBJECTIVE: The purpose of this study was to evaluate the therapeutic efficacy and toxicity of high dose cisplatin-cyclophosphamide combination chemotherapy on patients with primary epithelial ovarian cancer. METHODS: A review of 63 patients previously diagnosed as primary epithelial ovarian cancer after initial operation and histology at Pusan National University Hospital from Jul. 1993 to Jun, 1997 was performed. Patients were received the combination chemotherapy including cisplatin 100mg/m2/day and cyclophosphamide 750mg/m2/day, repeated 6 cycles every 4 weeks. The mean age was 48 years old, and previous surgical procedures were total abdominal hysterectomy and bilateral salpingo-oophorectomy with omentectomy. The patients were classified into FIGO stage and pathologic results. RESULTS: The clinical response rate was 100% in the FIGO stage Ic patients with PC combination chemotherapy, 100% in stage II, 53.5% in stage III, and 25% in stage IV. The overall response rate was 69.8%. The 3-year survival rate according to the treatment groups was 93.3% in stage Ic group, 60% in stage II, 50% in stage III and 0% in stage IV. The mean survival duration was 34.6 months. Hematologic toxicities in cisplatin-cyclophosphamide chemotherapy were neutropenia and anemia. Nausea and vomiting were the most common side effects and occurred in 96.8%. Most of the toxicities were grade 1 and 2. CONCLUSION: The combination chemotherapy with cisplatin-cyclophosphamide is relatively safe and effective method in the treatment of primary epithelial ovarian cancer.

The aim of this study was to determine whether losartan, an angiotensin II (Ang II) type 1 (AT1) receptor could influence the CA release from the isolated perfused model of the rat adrenal medulla. Losartan (5~50 micrometer) perfused into an adrenal vein for 90 min produced dose- and time-dependent inhibition of the CA secretory responses evoked by ACh (5.32 mM), high K+ (56 mM, a direct membrane depolarizer), DMPP (100 micrometer) and McN-A-343 (100 micrometer). Losartan failed to affect basal CA output. Furthermore, in adrenal glands loaded with losartan (15 micrometer) for 90 min, the CA secretory responses evoked by Bay-K-8644 (10 micrometer, an activator of L-type Ca2+ channels), cyclopiazonic acid (10 micrometer, an inhibitor of cytoplasmic Ca2+-ATPase), veratridine (100 micrometer, an activator of Na+ channels), and Ang II (100 nM) were markedly inhibited. However, at high concentrations (150~300 micrometer), losartan rather enhanced the CA secretion evoked by ACh. Collectively, these experimental results suggest that losartan at low concentrations inhibits the CA secretion evoked by cholinergic stimulation (both nicotininc and muscarinic receptors) as well as by membrane depolarization from the rat adrenal medulla, but at high concentration it rather inhibits ACh-evoked CA secretion. It seems that losartan has a dual action, acting as both agonist and antagonist to nicotinic receptors of the rat adrenal medulla, which might be dependent on the concentration. It is also thought that this inhibitory effect of losartan may be mediated by blocking the influx of both Na+ and Ca2+ into the rat adrenomedullary chromaffin cells as well as by inhibiting the Ca2+ release from the cytoplasmic calcium store, which is thought to be relevant to the AT1 receptor blockade, in addition to its enhancement of the CA release.

PURPOSE: This study aimed to analyze the mobility of newly graduated nurses from regions where their nursing schools were located to regions where they took up their first jobs, and to identify factors influencing nurses' mobility. METHODS: Data from the Graduates Occupational Mobility Survey, collected annually from 2010 to 2014 by the Korea Employment Information Service, were analyzed. The sample consisted of 1,488 graduates and 1,229 nurses who were employed on a full-time basis in hospitals. Multiple logistic regression analysis was conducted to identify factors associated with geographic mobility. RESULTS: Among the nurses working in hospitals, 69.2% had their first jobs in their nursing school regions and 11.3% in their high school regions. Fifty-two percent of the nurses worked in the capital region; 47.2% thereof had moved from a non-capital region. Nurses were more likely to work in their nursing school region when they were female, were older, graduated from a high school located in their nursing school region, graduated from a college (vs. university), had a lower nursing school performance, and expected lower monthly wage, compared with those who left their nursing school region. CONCLUSION: Education and remuneration policies are required to reduce geographical mobility to the capital region.

Acquired tufted angioma is a benign, slowly progressive angioma with a typical histological pattern that was first described by Wilson-Jones in 1976. We report a case of acquired tufted angioma in a 19 year old female who had erythematous papules and plaques on the right thigh. Histopathological findings showed multiple capillary lobules in a cannonball arrangement scattered throughout dermis, which was diagnostic of acquired tufted angioma.

BACKGROUND: It has been suggested that the regulation of hair growth might involve complex interaction between dermal papilla cells and hair matrix cells. Dermal papilla cells secrete diffusible factors that would act an hair matrix cells. During anagen the papilla appears to have prominent capillary loop, whereas in telogen it is nonvascularized. Vascular endothelial growth factor(VEGF) was recently reported to be produced by dermal papilla cells in rats. OBJECTIVES: We performed this study in order to evaluate the effect of VEGF on human hair growth in vitro and on the proliferation of dermal papilla cells and to define the splice forms of VEGF. METHODS: To detect the isoforms of VEGF, RT-PCR was performed on RNA isolated from dermal papilla cells and RT-PCR products were hybridized with VEGF-specific oligonucleotide probe located in exon 4. Isolated human hair follicles were cultured with various concentrations of VEGF165 and VEGF121. Hair follicle growth was measured by an Olympus inverted microscope with an eyepiece measuring graticule. RESULTS: The following results were obtained from this study. 1. Southern hybridization and size calculation of RT-PCR products revealed that mRNA species corresponding to 121, 165, 189, and 206 amino-acid forms of VEGF were praduced by cultured human dermal papilla cells. 2. 10 ng/ml of rhVEGF165, 0.1 ng/ml of rhVEGF165 and 10 ng/ml of rhVEGF121 stimulated follicle elongation in vitro(p < 0.05). 3. rhVEGF165 and rhVEGF121 had no effect on the numbers and thymidine incorporation of dermal papilla cells. CONCLUSION: These results suggest that VEGF is produced by dermal papilla cells and is able to promote hair growth in vitro. Increased hair growth by VEGF might occur other than by proliferation of dermal papilia cells.

Canavan disease(CD) is a rare autosomal recessive leukodystrophy caused by the deficiency of aspartoacylase and the accumulation in brain of N-acetylaspartate(NAA). CD has been reported mainly Ashkenazi Jews but also occurs in other ethnic groups. Usually it presents as early as the third month of life with megalencephaly, hypotonia later progressing to hypertonia, psychomotor and mental retardation, blindness, occasionally deafness and seizure. Diagnosis is based on the clinical feature, N-acetylaspartic aciduria, radiologic and pathologic findings. Histologically, the affected white matter shows extensive vacuolation and demyelination. There is no treatment for CD and the only prevention is through genetic counselling and prenatal diagnosis. We experienced a case of Canavan disease that was presented with hypotonia and developmental delay. Diagnosis was confirmed histologically. Radiologic findings are extensive high signal throughout the white matter on T2-weighted MRI and increased NAA peak and decreased choline peak of the white matter on MR spectroscopy.
