Vibrio cholerae is mainly known to cause gastrointestinal infection after seawater exposure or raw seafood intake. It is rarely reported to cause cellulitis or sepsis, but threre has been no known case after acupuncture. Herein, We report a 56-year-old cirrhotic patient of non-O1, non-O139 Vibrio cholerae septicemia caused by cellulitis of both lower extremities after acupuncture.

Objectives: The purpose of this study was to examine the electromyographic activities of the erector spinae muscle of the back and the rectus femoris muscle of the thigh, and to measure the angles of the spinal and knee flexions in order to determine the effect of wearing a back belt. Methods: Fifteen healthy males participated in the study. Surface electromyography was used to measure the level of muscle activities at the two muscle groups. The Simi system, utilizing two-dimensional analysis of movement, was used to examine the range of motion of the back and low extremity. Results: Firstly, the angle of the spinal flexion was significantly less in the back-belt-wearing group than in the control, and that of the knee flexion was significantly increased in the back-belt-wearing group. Secondly, there was no significant change in the electromyographic signals of the erector spinae muscle of the back and the rectus femoris muscle of the thigh. Conclusions: The use of back belts helps workers to correct their posture when lifting boxes. It can therefore protect workers from acute back injuries.

Purpose: To gain insight on the role of AP-1 in transcriptional regulation of vimentin gene during differentiation of HL-60 cells by 12-O-tetradecanoylphorbol-13-acetate (TPA), the levels of vimentin mRNA and AP-1 have been investigated with Northern blot hybridization and DNA mobility shift assay. Materials and Methods: HL-60 cells were grown in RPMI 1640 medium supplemented with 10% heat-inactivated fetal calf serum and antibiotics in a humidified 5% CO_2 at 37℃. Total RNA was prepared by a modification of the method of Karlinsey et al. Northern blot hybridization was performed by the method of Virca et al. EcoRI fragment of pVIM-GEM was used as probe for vimentin mRNA. DNA mobility shift assay was performed by the method of Lim et al. End labeled DNA probe(Upper strand, 5'-CGCTTGATGAGTCAGCCG- 3') for AP-1 binding activity was mixed with nuclear extracts in a 20 μl reaction volume containing 300 mM KCI, 60 mM HEPES, pH 7.9, 25 mM MgCI_2, 1 mM EDTA, 1 mM DTT, 60% glycerol, and 2 ㎍ of poly[dI-dC]. Results: TPA increased vimentin mRNA levels, with maximal stimulation reached at 24 hr. The level of vimentin mRNA was induced in proportion to the concentration of TPA. TPA-induced vimentin mRNA was almost reduced by actinomycin-D pretreatment. TPA-induced stimulation of vimentin gene was completely reduced by staurosporin pretreatment. In DNA mobility shift assay, AP-1 newly appeared at 24 hr during TPA-induced differentiation and was almost not detected after the pretreatment of staurosporin. Conclusions: These results suggest that the induction of vimentin mRNA during TPA-dependent differentiation in HL-60 cells may be mediated by protein kinases C signal transduction and AP-1 is important to transcriptional regulation.

This experiment was carried out to determine non-destructively water content in a intact fried noodle in oil by portable near-infrared system. Water content was ranged from 0 to 14.3w/w% and the near infrared (NIR) measurements were made on 70 intact samples over the spectral range 1100-1750nm. We found the variation of absorbance band due to OH vibration of water in the noodles depending on the concentration change around 1450nm in the second derivatives spectra. Partial least squares(PLS) regression models were set up using a calibration set(42 E.A.) and a validation set(28 E.A.) between the NIR response and value from loss on dry. Various pretreatments of the spectra were examined: the smallest stnadard error of prediction(0.35%) was obtained using autoscaling spectra over 1100-1700nm. 10 factors were required for the PLS model to give a good relationship between the spectral information and the noodle water content. In order to validate the developed calibration model, routine analyses were performed using other intact noodles. Water contents from the NIR calibration model were compared with the values from loss on dry and the results showed good correlation with those of loss on dry. This study showed that the rapid and non-destructive determination of water content in a intact fried noodle in oil was successfully performed by portable NIR system.

6-(3.4-Dichlorophenyl)amino-7-chloro-5.8-quinolinedione (RCK50) was tested for antifungal activities in mice systemically infected with Candida albicans. The therapeutic potential of RCK50 was also assessed in comparison with ketoconazole. RCK50 had ED_50 0.22±0.01 ㎎/㎏. Ketoconazole as a positive control had ED_50 6.00±1.70 ㎎/㎏. Intraperitoneally administered RCK50 at the ED_50 for 7 days and 14 days reduced Candida albicans colony count in the kidneys and liver. And administered RCK50 at the ED_50 for 14 days improved survival rates. The genotoxicities of RCK50 had been evaluated. RCK50 was negative in Ames test with Salmonella typhimurium and chromosomal aberration test in CHL cells. RCK50 did not show any clastogenic effect in mouse peripheral blood and was negative in mouse micronucleus assay. These results indicate that RCK50 has no genotoxic potential under these experimental conditions. Acute oral toxicity studies of RCK50 were carried out in ICR mice of both sexes. RCK50 did not show acute oral toxicities and LD_50 values were over 2.850 ㎎/㎏ in ICR mice.

<P><B>Background</B></P><P>Hepatitis B virus (HBV) infection leads to hepatic and extrahepatic manifestations including chronic kidney disease (CKD). However, the association between HBV and CKD is not clear. This study investigated the association between chronic HBV infection and CKD in a nationwide multicenter study.</P><P><B>Methods</B></P><P>A total of 265,086 subjects who underwent health-check examinations in 33 hospitals from January 2015 to December 2015 were enrolled. HBV surface antigen (HBsAg) positive cases (n = 10,048), and age- and gender-matched HBsAg negative controls (n = 40,192) were identified. CKD was defined as a glomerular filtration rate (GFR) < 60 mL/min/1.73 m<SUP>2</SUP> or proteinuria as at least grade 2+ of urine protein.</P><P><B>Results</B></P><P>HBsAg positive cases showed a significantly higher prevalence of GFR < 60 mL/min/1.73 m<SUP>2</SUP> (3.3%), and proteinuria (18.9%) than that of the controls (2.6%, <I>P</I> < 0.001, and 14.1%, <I>P</I> < 0.001, respectively). In the multivariate analysis, HBsAg positivity was an independent factor associated with GFR < 60 mL/min/1.73 m<SUP>2</SUP> along with age, blood levels of albumin, bilirubin, anemia, and hemoglobin A1c (HbA1c). Likewise, HBsAg positivity was an independent factor for proteinuria along with age, male, blood levels of bilirubin, protein, albumin, and HbA1c. A subgroup analysis showed that HBsAg positive men but not women had a significantly increased risk for GFR < 60 mL/min/1.73 m<SUP>2</SUP>.</P><P><B>Conclusion</B></P><P>Chronic HBV infection was significantly associated with a GFR < 60 mL/min/1.73 m<SUP>2</SUP> and proteinuria (≥ 2+). Therefore, clinical concern about CKD in chronic HBV infected patients, especially in male, is warranted.</P>
