A total of 100 Vibrio spp. strains were examined for production of various extracellular enzyme and for plasmid content plasmid were subjected to digestion with restriction enzymes. Most of them produced extracellular enzyme more than one, especially V. parahaemolyticus and V. cholerae non-01 strains were showed production of various extracellular enzymes. About the 55% Vibrio spp. have the plasmid more than one, but a lot of Vibrio spp. (about 45%) did not possess any plasmid. Most of these plasmid various derivatives ranged from 2.4 kb-23 kb, especially two strains of V. mimicus and one strain of V. furnissii carried one high-molecular weight plasmid (molecular weight ranging between 70 kb-100 kb). Results of restriction analysis for plasmid of this three strains were by no means the rule. For detection of tdh and ctx gene, the virulence factor involved in the pathogenesis, we carried out the TDH, CT assay, PCR amplification, and hybridization. A total 11 strains were produced TDH, involved in 4 strains of V. parahaemolyticus and 1 strain of V. cholerae non-01 from clinical isolates and 6 strains of environmental isolates. Nine strains of 11 strains, involved in 4 strains of V. parahaemolyticus and 1 strain of V. cholerae non-01 from clinical isolates and 4 strains of V. parahaemolyticus from environmental isolates, could be successfully amplified in 400 bp by PCR, no amplification products were obtained from TDH-negative strains. The PCR results were consistent with DNA hybridization. In the experiments of ctx gene detection, in all, 3 strains of V. cholerae non-01 from clinical isolate and 1 strains of V. cholerae non-01 from environmental isolate were observed CT- positive. These CT-producing strains amplified in 302 bp by PCR for the detection of ctx gene. All CT-producing strains hybridized with digoxigenin-labeled DNA probe, while CT-negative strains did not hybridize. Also hybridization tests results for detection of ctx gene consistent with PCR.

PURPOSE: The purpose of this study was to analyze the research on adherence for secondary prevention in patients with coronary artery disease (CAD) in Korea, and to identify the strategies for improvement that should be included in future studies. METHODS: Electric literature searches were conducted for Pubmed, CINAHL, RISS4U, KISTI, DBpia, KoreaMed, National Assembly Library, and National Library of Korea. A total of forty two articles published between 1986 and 2009 were selected based on established inclusion criteria. RESULTS: Forty research papers were related to nursing, and there was only one research paper focused on elderly people with CAD. There were no papers using concept analysis, qualitative study, or randomized controlled clinical trial. Almost all definitions of adherence were adopted from outdated compliance definitions with the attribute of 'paternalistic obligation'. Measurement tools were not based on theoretical framework of adherence but borrowed from tools for measuring self-care, health behavior, or self-efficacy. Overall patient's adherence was analyzed in most studies, except for a few studies which focused on diet and exercise only. Educational strategy was the main strategy used in intervention studies. CONCLUSIONS: The concept of adherence and measurement tools need to be clarified, along with development of the specific adherence interventions according to the type of adherence in patients with CAD.

PURPOSE: Defensins are important components of innate immune system. These peptides have antimicrobial activity against a wise variety of pathogens that associated with burn wound infection. In particular, human beta-defensins are expressed in normal epidermal region and showed differential expression of some skin disease. We investigated that expression of human beta-defensin by in vitro and ex-vivo by thermal condition. METHODS: To investigate the expression of human beta-defensins in acute burn condition, we cultured keratinocytes and used to rat's skin at this experiment. After thermal condition, we showed the expression of beta-defensins-2 (hBD-2), -3 (hBD-3), keratins, keratinocyte differentiation and junction protein levels by RT-PCR and immunohistochemistry (IHC). RESULTS: HBD-2 & involucrin were down-regulated from 1 hr to 8 hrs in mRNA level. But others were not changed in mRNA level. In protein level, hBD-3 was decreased but pan-cytokeratin and beta-catenin were not changed. CONCLUSION: HBD-2 was down-regulated in thermal injury. Because thermal injury could induce the influence of keratinocyte differentiation and the decrease of skin protection ability. Our results suggested that human beta-defensins plays an important role in protection by several injury.

PURPOSE: The purpose of the study was to evaluate the effects of postoperative oral care using cold therapy on nausea, vomiting and oral discomfort after laparoscopic myomectomy. METHOD: The study was conducted with an experimental group (n=29) and a control group (n=35) sampled from patients admitted to a women's hospital in a metropolitan city in Korea. Data were collected between October 10, 2011 and January 31, 2012 and analyzed using Chi-square, Fisher's exact test, t-test, and repeated measure ANCOVA with SPSS/WIN 19.0. RESULTS: After the intervention, postoperative nausea (p<.001) and oral discomfort for patients in the experimental group were significantly lower than in the control group. There were significant differences in the presence of vomiting between both groups at 12 hours (p<.001) and 24 hours (p=.003) after leaving the recovery room. CONCLUSION: Oral care using cold therapy was found to be an effective nursing intervention for reducing postoperative nausea, vomiting and oral discomfort up to 24 hours after recovery in patients with laparoscopic myomectomy.

Acinetobacter calcoaceticus-Acinetobacter baumannii (A. calcoaceticus-A. baumannii) complex, which includes A. calcoaceticus (genospecies 1), A. baumannii (genospecies 2), Acinetobacter genospecies 3 and 13, has been identified as A. baumannii by automated bacteria identification system. The purpose of this study is to develop rapid genospecies classification of A. calcoaceticus-A. baumannii complex by molecular techniques. Random amplified polymorphic DNA (RAPD) and restriction fragment length polymorphism (RFLP) were determined for 4 reference strains and 80 isolates of A. calcoaceticus-A. baumannii complex from clinical sources. Four and eleven RAPD patterns were observed among the reference strains and the isolates, respectively. RAPD might be useful for genomic typing but not for genospecies classification of Acinetobacter spp. RFLP of 16S-23S rRNA intergenic spacer gene with three selected restriction enzymes (ApaLI, SwaI, and SalI) showed only four RFLP patterns in the reference and the isolates. Of 80 isolates, 10 of A. calcoaceticus (12.5%), 50 of A. baumannii (62.5%), 11 of A. genospecies 3 (13.75%), and 9 of A. genospecies 13 (11.25%) were classified by RFLP. This result suggests that RFLP of 16S-23S rRNA intergenic spacer gene of A. calcoaceticus-A. baumannii complex might be useful for genospecies classification.

BACKGROUND: The goal of antihypertensive therapy will be to extended the life expectancy of hypertensive patients to that of subjects without high blood pressure. Hypertension treatment in the 1990s will focus on the mechanisms by which blood pressure is lowered by various antihypertensive agents, as will as individualization of drug therapy. In recognition of their lack of adverse lipid effects and their tolerability, first line therapy with alpha blocker, angiotensin converting enzyme inhibitors and calcium antagonists will become increasingly commom. We studied a new dihydropyridine calcium antagonist barnidipine to evaluate the efficacy and safety in patients with essential hypertension. METHODS: The rabit aortic rings were cut and mounted on the force transducer to record an isometric tension on polygraph. To elucidate the mechanism of saponin effect on vascular smooth muscle, the contractility of the vascular smooth muscle were measured under vatying experimental condition. RESULTS: 1) The baseline sitting systolic and diastolic blood pressure after 4 weeks washout period were 154.+/-15.9mmHg and 1.0+/-8.2mmHg. At the end of 8 weeks of therapy sitting systolic and diastolic blood pressure were 126+/-9.5mmHg and 84.5+/-4.6mmHg which declined statistically significant(p<0.05). 2) The pulse rates did not change significantly during treatment period(70.0+/-6.6 beats / min at baseline, 70.9+/-7.2 beats / min at 2 weeks, 71.2+/-5.0 beats / min at 4 weeks, 72.8+/-8.5 beats / min at 6 weeks, and 71.9+/-6.8 beats / min). 3) The adverse reactions due to branidipine were reported in 2 patients(6.5%) with headache, 2 patients(6.5%) with facial flushing, 1 patient(3.4%) with dizziness and 1 patients(3.4%) with nausea and vomiting). 4) The abnormal laboratory findings due to barnidipine were reported in 1 patient with increased total bilirubin and GPT, 1 patient with increased transaminase and 1 patient with CK but another findings were normal. CONCLUSION: These results indicate that barnidipine is effective and safe antihypertensive agent in the treatment of essential hypertension.

Symptoms of a peritoneal progression from ovarian cancer are nonspecific such as abdominal pain, abdominal distention and more. Many imaging studies and serum CA-125 help diagnosis. However, it is difficult to exclude the instances of the diffuse peritoneal diseases that mimic carcinomatosis. The elevated CA-125 level usually correlates with the peritoneal carcimatosis, but it is often found in other peritoneal diseases. Therefore, the pathologic confirmation is necessary because of other mimicking diseases. In our case, CA-125 levels were elevated. Abdominal computed tomography finding was suspected a peritoneal tuberculosis but the pathologic result was the peritoneal carcimatosis, eventually.

BACKGROUND: Bacterial extracellular protease has been implicated as an important virulence factor in several infections. In Vibrio sp., protease involvement has been demonstrated by the decreased virulence of protease-deficient mutants. We characterized the protease from V. parahemolyticus bc-7 with purification. METHODS: 100 Vibrio isolates from sea water and sea products were studied. The bacteria grown in Brain Heart Infusion broth were screened for protease production by incubating on tryptic soy agar plate containing gelatin and subsequently flooding the plate with 12.5% HgCl2-1M HCl. A clear zone indicated protease activity. Optimal conditions for protease production were determined by pH, temperature and NaCl concentration. Protease was purified from culture filtrates and its biological analysis was carried out. RESULTS: Out of Vibrio isolates studied, V. parahemolyticus bc-7 produced protease in the highest titer. Maximal yields of the protease was obtained when the bacteria were grown in Brain Heart Infusion broth with initial pH of 8.0, 3% NaCl at 30degrees C. Production of the protease was optimal during the late exponential phase. Homogeneity of the purified protease was demonstrated by revealing a 65kDa band on SDS-PAGE. The protease was stable at 50degrees C and 70% of the activity was lost by heating at 60degrees C for 30 min. The protease was stable at a pH between 5~10, but under pH 4.0, the activity was lost completely. CONCLUSION: General and serological studies are warranted to clarify the diffences and further characterize the protease as a virulence factor in Vibrio sp.
