Objectives : The EPDS (Edinburgh Postnatal Depression Scale) is a lO-items self-report scale designed as a specific instmment to detect postnatal depression by Cox et al. (1987). This study was to determine the optimal cut-offpoint ofthe K-EPDS for postpartum depression in Korea. Methods : The 239 pregnant women assessed their own psychiatric features with the Korean version of the Edinburgh Postnatal Depression Scale (K.-EPDS), Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI), Rosenberg Self-Esteem Scale (RSES) and Marital Satisfaction Scale (MSS) at 6 months ofpregnancy, 1 week after delivery, and 6 weeks after delivery. Subjects above 9 points of K-EPDS at 6 week after delivery were interviewed with Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-I) to confirm postpartum depression. Results : The prevalence of postpartum depression was 12.6% (30/239 pregnant women) in our study. The total scores of K-EPDS at 6 weeks after delivery were higher significantly than those of nonnal group. The score gap of K-EPDS between the depressed pregnant group and the normal pregnant group was increased after the delivery. However, there were no differences in the epidemiological characteristics and the BDI scores at 6 weeks after delivery between groups. Using the AUC (area under the curve), the optimal point to assess the postpartum depression was revealed as 6 weeks after delivery (AUC=85.8%) or 24 weeks of pregnancy (83.7%). The cut-offpoint of K-EPDS to detect postpartum depression among pregnant women was 9/10score of K-EPDS (AUC= 81.8%). Conclusion : In the K-EPDS, cut-off score of 9/10 was optimal to assess the postpartum depression, and K-EPDS at 6 weeks of delivery was more useful than any other point of time. K-EPDS administrated during pregnancy may be a useful tool to find the vulnerability on the postpartum depression.

Objective : The use of herbal therapy is becoming an increasingly attractive approach for the treatment of various inflammatory disorders. The Alpiniae officinari Rhizoma is popular in Aisa as a traditional herbal medicine. Alpiniae officinari Rhizoma is a species of the ginger family(Zingiberacease). Method : This study was performed to investigate the anti-inflammatory effect of Alpiniae officinari Rhizoma extract by the methods of "carrageenan induced paw edema" and "Lipopolysaccharide-induced inflammatory mediators in mouse macrophage RAW 264.7 cells". Result : We suggest that Alpiniae officinari Rhizoma extract decreased paw volume induced by plantar injection of carrageenan. Also Alpiniae officinari Rhizoma extract inhibited nitric oxide, prostaglandin E₂production and induced nitric oxide synthase, cyclooxygenase-2 protein expression in Mouse macrophage RAW 264.7 cells stimulated with lipopolysaccharide. Conclusion : This study shows that Alpiniae officinari Rhizoma extract seems to have anti-inflammatory effect by inhibition of nitric oxide, prostaglandin E_(2) production and nitric oxide synthase, cyclooxygenase-2 protein expression.

Objectives : This study was designed to evaluate cytotoxicity of TAFMAG, which is a trade name of natural mineral fiber mined and produced in China. Methods : The cytotoxicity of TAFMAG was evaluated by measuring iron content, lipid peroxidation, erythrocyte hemolysis, and cytotoxicity in vitro. These results were compared with the data of chrystotile and wollastonite as a positive and negative control, respectively. Results : There was significant increase of Fenton activity in TAFMAG and chrysotile with dose-response pattern. The iron chelating agent, desferrioxamine, significantly decreased Fenton activity of the particulates except wollastonite. TAFMAG and chrysotile fibers significantly increased malondialdehyde concentration from lipid peroxidation of the red blood cell membrane. In erythrocyte hemolysis test, TAFMAG & chrysotile had stronger effect on erythrocyte hemolysis than wollastonite with the concentration of 1,000g/ml. Furthermore, TAFMAG was more hemolytic than chrysotile with the concentration of 5,000g/ml. There was a significant cytotoxic effect in TAFMAG and chrysotile on RAW cell compared with wollastonite. Conclusions : In vitro study suggested that TAFMAG may have a similar health hazard as usual asbestos.

The adenocarcinomic human alveolar basal epithelial cells (A549) are commonly used for in vitro cell models of respiratory toxicity. In this study, we intended to establish in vitro culture models for respiratory toxicity testing by comparing air-liquid interface (ALI) conditions of A549 cells with liquid-liquid interface (LLI). A549 cells were seeded at 1*10^5 cells/well in an apical compartment of 12 well insert (Greiner Bio-one). Culture medium was added to the basolateral compartment and was replaced every 2-3 days in contact with cells for nutrient supply via the membrane. The medium was added only to the basolateral compartment in ALI culture condition while it was added to both apical and basolateral part in LLI culture method. During the culturing periods, A549 cells in ALI condition formed into multilayered epithelium with time, while the cells grown in LLI conditions formed into simple squamous epithelium over time. Because A549 cell is composed of basal epithelial cells, ciliated epithelial cells was not identified in this study during the 4 weeks of culturing period. Instead, epithelial specific morphology was well identified by hematoxylin and eosin staining after 4 weeks of culturing. Since cell culture interfaces and culture period affect cell formation, culture conditions need to be further optimized for in vitro respiratory toxicity test models.

Ascochlorin, a non-toxic prenylphenol compound derived from the fungus Ascochyta viciae, has been shown recently to have anti-cancer effects on various human cancer cells. However, the precise molecular mechanism of this anti-cancer activity remains to be elucidated. Here, we investigated the effects of ascochlorin on hypoxia-inducible factor-1α (HIF-1α) and vascular endothelial growth factor (VEGF) expression in human epidermoid cervical carcinoma CaSki cells. Ascochlorin inhibited epidermal growth factor (EGF)-induced HIF-1α and VEGF expression through multiple potential mechanisms. First, ascochlorin selectively inhibited HIF-1α expression in response to EGF stimulation, but not in response to hypoxia (1% O(2)) or treatment with a transition metal (CoCl(2)). Second, ascochlorin inhibited EGF-induced ERK-1/2 activation but not AKT activation, both of which play essential roles in EGF-induced HIF-1α protein synthesis. Targeted inhibition of epidermal growthfactor receptor (EGFR) expression using an EGFR-specific small interfering RNA (siRNA) diminished HIF-1α expression, which suggested that ascochlorin inhibits HIF-1α expression through suppression of EGFR activation. Finally, we showed that ascochlorin functionally abrogates in vivo tumor angiogenesis induced by EGF in a Matrigel plug assay. Our data suggest that ascochlorin inhibits EGF-mediated induction of HIF-1α expression in CaSki cells, providing a potentially new avenue of development of anti-cancer drugs that target tumor angiogenesis. 113: 1302-1313, 2012. ⓒ 2011 Wiley Periodicals.
