Objective To study the protective immunity and antibody(IgG,IgG1 and IgG2a)response against adult and larva infection of T.spiralis Korean isolate in rats.Methods Fony-six rats were randomly divided into 7 groups.Group A(A1,A2,10 rats)was used for the determination of protective efficacy from adult stage infection,group B (B1,B2,14 rats)was for the protective efficacy from muscle larva stage infection,group C(C1,C2,17 rats)was for challenge control,and group D(5 rats)served as normal control.Rats in groups A,B and C were infected with 1000 T.spiralis muscle larvae,and the infected rats were treated with flubendazole(20 mg/ks,10 d)at day 7(A1,A2) and at day 30(B1,B2).Rats in groups A and B were re-infected with 500 T.spiralis muscle larvae at day 10 after treatment.Rats in groups A1 and B1 were killed at day 7 and day 30 to inspect the reduction of adult worms in the intestines.Rats in groups A2 and B2 were killed at day 30 to detect the reduction of muscle larvae in diaphragms.Rats in groups C and D were killed at the same time,and all rats were bled at the same time.Specific anti-Trichinella IgG,IsG1 and IgG2a were detected by ELISA.Results Adult stage infection induced protective efficacy by 100% against adult stage and by 99.96% against larva stage.Larval stage infection induced protective efficacy by 99.92% against adult stage and 99.89% against muscle larvae.Anti-muscle stage larval ES Ag(IgG 3.0,IgG1 2.2,IgG2a 0.8)and anti-adult crude Ag antibodies(IgG 1.9,IgG1 0.8,IgG2a 0.3) significantly increased in the muscle larval stage infection compared to normal control(IgG 0.5,IgG1 0.1,IgG2a 0.1)and adult stage infection(IgG 0.5,IgG1 0.09,IgG2a 0.09) (P<0.01).Higher specific IgG1 antibody(IgG1 2.2) in larva stage infection was shown than specific IgG2a antibody response(IgG2a 0.8)(P<0.01).Conclusion Protective immunity against both adult and larva worms has been induced from adult and muscle larva stage infections of T.spiralis.

[Objective] To study the synergic effect of praziquantel (PZQ) and host acquired immunity on Clonorchis sinensis. [Methods] Acquired immunity to C. sinensis was induced by immunization with crude adult worm antigen (AW Ag) and excretory-secretory antigen (ES Ag) or infection with C. sinensis metacercariae. The effect was assessed by the worm reduction rate compared with the control groups after challenge infection with 50 metacercariae and treated orally with a subcurative dose of praziquantel (50 mg/kg). Significant test was performed by analysis of variance (ANOVA) and Nparl way Kruskal-Wallis test. All calculations were performed by PC-SAS system. [Results] 1. PZQ was more effective against C. sinensis larvae than against adult worms in the control (P＜0. 001), ES Ag (P＜0.01) or crude AW Ag immunization group (P＜0. 001). 2. As compared with the control, the worm reduction rate after challenge infection was significantly higher (P＜0. 001) in ES Ag immunized group (35.60%) and metacercaria infection group (97.5 % ) and less in crude AW Ag group (23.4 %). The PZQ efficacy was significantly enhanced in ES Ag immunized group. [Conclusion] The efficacy of PZQ against C. sinensis could be synergically enhanced in rats by inducing host acquired immunity.

PURPOSE: This study was aimed to evaluate the methodological issues and comprehensiveness of workplace bullying instruments and to suggest a taxonomy of psychological abuse. METHODS: Nineteen instruments applied in health care organizations and 469 questionnaire items mainly regarding psychological abuse were collected through a literature review. Three researchers classified the questionnaire items according to a “taxonomy of psychological abuse in the workplace.” RESULTS: Many instruments of workplace bullying were developed in the 2000s using a reflective measurement model, but their psychometric property was not sufficient and the measurement model is questioned. Based on the questionnaire items, the “taxonomy of psychological abuse in the workplace” was modified by adding two new subcategories (unachievable work and unfair treatment) and clarifying some operational definitions. According to the modified taxonomy of 11 (sub)categories, the reviewed instruments assessed 6.5 (sub)categories on average. No instrument measured all (sub)categories. Category 4.2 (disrespect, humiliation, and rejection of the person) was measured in all instruments, followed by Categories 5 (professional discredit and denigration) and 1.2 (social isolation) behaviors. CONCLUSION: The current instruments are not comprehensive enough. It is suggested that the modified taxonomy is verified and guide more reliable and inclusive instruments in the future. Furthermore, a formative measurement model, which defines a bullying as an inventory of different types of behaviors, should be used.

PURPOSE: The purpose of the study was to explore the experience of patients with facial burn injuries regarding their interpersonal relationships. METHODS: The phenomenological research method was used. Participants of the study consisted of five males and three females. Data were collected through individual in-depth interviews from November, 2014 to February, 2015 and analyzed using Colaizzi's method. RESULTS: Five theme clusters were extracted that described patients' experiences. They are “being a lonely foreigner,”“closing my mind toward the world,”“hiding hurt feelings,”“companion of my face,” and “communicating with the world”. CONCLUSION The results of this study provide a deep understanding and insight into the experience of interpersonal relationships among facial burn patients. The development of a comprehensive program including physical, psychological, and social aspects is recommended to address the problems facial burn patients encounter in interpersonal relationships and to facilitate interaction.

BACKGROUND: We utilized results from the ARTEMIS DISK Global Antifungal Surveillance Program to evaluate the species distribution and fluconazole and voriconazole susceptibilities of yeast isolates from clinical specimens in South Korea from 2001 to 2007. METHODS: Data were collected on 5,665 yeast isolates from all body sites at three locations. All investigators tested clinical yeast isolates using the CLSI M44-A disk diffusion method. Test plates were automatically read and results were recorded using the BIOMIC image analysis plate reader system (Giles Scientific, USA). Species, drug, zone diameter, susceptibility category, and quality control results were collected quarterly via e-mail for analysis. RESULTS: Candida albicans was the most common isolate, but a progressive increase in non-C. albicans Candida and noncandidal yeast species has been observed in recent years. The overall percentages of isolates in each category (susceptible, susceptible dose dependent, and resistant) were 98.8%, 0.5%, and 0.7% and 99.2%, 0.2%, and 0.6% for fluconazole and voriconazole, respectively. Candida of 3 species exhibited decreased susceptibility to fluconazole (<90% S) in the order of that seen with the resistant (R) species: C. krusei, C. guilliermondii, and C. glabrata. Emerging resistance to fluconazole or voriconazole was documented among isolates of Cryptococcus neoformans, Trichosporon spp., and Rhodotorula spp. CONCLUSIONS: The species distribution and antifungal susceptibilities of yeasts may differ according to specimen type, testing method, hospital, and geographic region. Therefore, further large-scaled, long-term surveillance studies are needed to isolate yeasts and to confirm the species distribution and antifungal susceptibilities of yeast isolates from clinical specimens in Korea.

Campylobacter jejuni commonly causes bacterial enteritis but rarely causes extraintestinal infection including bacteremia. We isolated C. jejuni from the blood culture of a 20-year-old man presenting with fever and headache and also from the blood culture of a 23-year-old man suffering abdominal pain and diarrhea. This organism grew in anaerobic culture, showed curved Gram-negative bacilli by Gram stain, and was identified by matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS).

BACKGROUND: Cinical and Laboratory Standards Institute (CLSI) recommends the use of cefoxitin disks instead of long-used oxacillin disks for screening methicillin-resistant isolates of staphylococci. The frequency of discrepant results and accuracy of the tests were evaluated by detecting mecA gene. METHODS: A total of 3,123 Stapylococci isolates from patients in Severance Hospital were tested during September 2005 to August 2006 by the CLSI-recommended test using both cefoxitin and oxacillin disks. The mecA gene was detected by PCR and the oxacillin minimum inhibitory concentration (MIC) was determined by using agar dilution method for the isolates with discrepant tests. RESULTS: Among 1,915 S. aureus islolates tested, one isolate was resistant to oxacillin disk but susceptible to cefoxitin disk; the isolate did not have mecA gene. Another isolate susceptible to oxacillin but resistant to cefoxitin had mecA gene. Among 1,208 coagulase-negative staphylococcal isolates, 15 isolates were resistant to oxacillin disk but susceptible to cefoxitin disk; the isolates did not have mecA genes. Two isolates susceptible to oxacillin disk but resistant to cefoxitin disk had mecA genes. Among the 16 Staphylococcus isolates that did not have mecA gene, 15 isolates had the oxacillin MICs of < or =2 microgram/mL and were considered as methicillin-susceptible, while 1 isolate with the MIC of 4 microgram/mL was considered as methicillin-resistant. CONCLUSIONS: Overall, 1.9% of staphylococcal isolates showed discrepant results when the screening tests were performed by using oxacillin and cefoxitin disks. None of the isolates resistant to oxacillin disk but susceptible to cefoxitin disk had mecA gene. In conclusion, the cefoxitin disk test is more reliable than oxacillin disk test in screening methicillin-resistant staphylococcal isolates.
