Newcastle disease (ND) is an infectious poultry disease that caused high mortality and reduced egg production. NDVs are regularly present in the domestic duck population. And ducks play a possible role in the maintenance and transmission of NDVs. While we were monitoring the Avian Influenza, NDVs were isolated from field samples by accident. So we analysed the biological and genetic characteristics of these viruses. Lentogenic NDVs were isolated from two farms among twenty breeder duck farms. The ages of ducks were 39 weeks old in the 'A' farm and 3~72 weeks old in the 'B' farm. And they were not inoculated with the NDVs vaccine. In the biological characteristics, the both viruses which separated from the farm 'A' and 'B' were thermostable. The amino acid sequence of a site from 112 to 119 in the fusion (F) protein was 'GKQGRLIG' which has monobasic motif in the samples of both farms. And this means the separated NDVs are lentogenic. Phylogenetic analysis was performed by entire nucleotide sequence of F protein. The virus strains from the A farm (MN095239) and the B farm (MN095240) belonged to class II genotype I. Using the analysis of whole F protein nucleic acid sequence, the MN095239 (GenBank) had homology with Ulster strain about 99.95% and the MN095239 (GenBank) had homology with KR/CK/KU_LBM255/09 strain about 99.89%. NDV surveillance is needed to investigate epidemiological relationship of domestic breeder duck isolates in Korea.

Ginseng has been widely used in Korea as a natural medicine due to its saponin contents. Although the total amount of ginseng stem and leaf saponins (GSLS) is 4~5 times higher than that of saponin in the root, the root is mainly used. This is due to two reasons: nervous system-stimulant activity of GSLS and pesticide residues in GSLS. In this study, residual agricultural pesticides were removed from GSLS using two types of bacterial treatments. Two GSLS treatment groups of chickens (GSLS-1 and GSLS-2) were established. The chickens were fed 0.4% GSLS-1 or GSLS-2 mixed with crop. We then evaluated the effects of GSLS on bodyweight and several immune parameters. At the end of the experiments, chickens fed GSLS-1 and red ginseng saponin had significantly higher growth rates (16.6% and 8.0%, respectively) compared to the vaccine control group treated with Noblis Salenvac-T. The group fed GSLS-1 also had the highest IgG titer that was significantly different at the end of experiments compared to the other groups. These findings imply that GSLS-1 is a good candidate feed additive for the chicken industry.

AIDS (Acquired Immunodeficiency Syndrome) known as 20th century's pest is spreading rapidly internationally, and the number of patients are increasing. Since the prevention vaccine has not been developed yet, the only available effective method for preventing AIDS is the health education. Most of the AIDS-infected persons are males, and especially over twenties of age. Therefore, it is necessary to measure the knowledge and attitudes on AIDS of male workers. The purpose of this study is to examine the knowledge, attitudes and education-needs of male workers on AIDS. The data were collected by a questionnaire survey of 977 workers who work in Seoul and Kyungki areas from September 1 thru October 4, 1997. The results were as follows: 1. We examined the level of knowledge on AIDS transmission, symptoms, diagnoses, and prevention methods. Even though respondents had a moderate level of AIDS-related knowledge, still sizable numbers believed that AIDS could be transmitted through casual contact. White-collar workers, higher education groups, higher income groups or those with age thirties showed respectively higher level of knowledge than the other comparison groups. 2. 85％ of the respondents recognized AIDS as a serious problem. Statistical analysis revealed that white-collar workers, higher education groups or those with age twenties had more positive attitudes towards a AIDS patient than their counterparts. 3. Over 80％ of the respondents replied that AIDS education in schools, work places, social agencies or by mass-media was necessary. 62.8％ of the respondents mentioned that government should play the major role in developing AIDS education program. 4. The prediction model of AIDS-education needs was examined with using the multiple logistic regression method. The education level and AIDS-related knowledge were turned to be statistically significant factors influencing positively the perceived needs of AIDS education.

Human epidermal growth factor receptor 2 (HER2) is a member of the epidermal growth factor receptor family of receptor tyrosine kinases that plays important roles in all processes of cell development. Their overexpression is related to many cancers, including examples in the breast, ovaries and stomach. Anticancer therapies targeting the HER2 receptor have shown promise, and monoclonal antibodies against subdomains II and IV of the HER2 extra-cellular domain (ECD), Pertuzumab and Herceptin, are currently used in treatments for some types of breast cancers. Since anti HER2 antibodies targeting distinct epitopes have different biological effects on cancer cells; in this research linear and conformational B cell epitopes of HER2 ECD, subdomain III, were identified by bioinformatics analyses using a combination of linear B cell epitope prediction web servers such as ABCpred, BCPREDs, Bepired, Bcepred and Elliprro. Then, Discotope, CBtope and SUPERFICIAL software tools were employed for conformational B cell epitope prediction. In contrast to previously reported epitopes of HER2 ECD we predicted conformational B cell epitopes $P1_C$: 378-393 (PESFDGDPASNTAPLQ) and $P2_C$: 500-510 (PEDECVGEGLA) by the integrated strategy and P4: PESFDGD-X-TAPLQ; P5: PESFDGDP X TAPLQ; P6: ESFDGDP X NTAPLQP; P7: PESFDGDP-X-NTAPLQ; P8: ESFDG-XX-TAPLQPEQL and P9: ESFDGDP-X-NTAPLQP by SUPERFICIAL software. These epitopes could be further used as peptide antigens to actively immune mice for development of new monoclonal antibodies and peptide cancer vaccines that target different epitopes or structural domains of HER2 ECD.

The HIV-1 p24(202-221) sequence ETINNEEEWDRVHPV HAGP contains a B-cell epitope with the earliest immune response and the highest antibody titer against anti-mouse sera obtained by immunization with p24 antigens. A novel mouse monoclonal antibody (mAb) was generated against the immunodominant B-cell epitope of the HIV-1 p24 capsid protein, p24(202-221). BALB/c mice were immunized with the four branched multiple antigenic peptide (MAP) containing the HIV-1p24(202-221) sequence, and antibody-secreting hybridoma were produced by fusion of mouse splenocytes with P3X63Ag8.653, mouse myeloma cells. One clone which produced the antigen-specific mAb named KI-24 (Isotype IgG1, light chain: ${\kappa}$) was identified. mAb KI-24 was highly specific for both the p24(202-221) and p24 proteins when analyzed by ELISA and Western blotting. Since p24(202-221) also contains a cytotoxic T-lymphocyte epitope, this specfic peptide epitope and the monoclonal antibody with specific reactivity against the p24 protein and p24(202-221) can be used in peptide vaccine development and p24 antigen detection from HIV patients.

Purpose: This study was done to examine mothers' acceptance and its influencing factors in daughters' human papillomavirus (HPV) vaccination to prevent cervical cancer. Methods: From July 20 to August 31, 2010, 220 mothers of unmarried daughters responded to self-administered questionnaires about their acceptance of HPV vaccination for their daughters and the optimal age for HPV vaccination. Descriptive statistics, univariate logistic and multiple logistic regression were used for data analysis with SPSS/WIN 12.0. Results: Mothers indicating their willingness to pay for their daughters to receive HPV vaccination accounted for 61.8%, and willingness with health insurance coverage, 84.5%. Mean optimal age for HPV vaccination was $19.78{\pm}3.96$) years. With self-payment the factor influencing mothers willingness was necessity of HPV vaccination (OR= 30.45, 95% CI=10.33~89.15). With health insurance coverage, income (OR=3.02, 95% CI: 1.19~7.62), necessity of HPV vaccination (OR=15.05, 95% CI=4.15~54.64), concern about HPV vaccine safety (OR=2.99, 95% CI=1.15~7.76), and experience of Pap test (OR=3.16, 95% CI=1.24~8.05) were factors influencing mothers willingness. Other influencing factors were optimal age for HPV vaccination, knowing about HPV (OR=7.66, 95% CI=2.19~26.82), and age of youngest daughter (OR=3.95, 95% CI=1.34~11.68). Conclusion: Financial support is anticipated for low income families in a primary approach to increase HPV vaccination. And focusing on earlier age and concerns about vaccination are necessary to gain mothers' acceptance.

Background: Evaluation of health-related quality of life (HRQOL) in cervical cancer patients is important in order to design the interventions for improving patient outcomes. Reports of HRQOL among cervical cancer patients in Indonesia are limited. Moreover, measurement using EQ-5D-3L is to our best knowledge has hitherto not been performed. This study aimed to examine the HRQOL of cervical cancer patients in Indonesia using EQ-5D-3L. Materials and Methods: A cross-sectional study was conducted by interviewing cervical cancer patients using the EQ-5D-3L questionnaire. Percentages of patients who reported having problems in each dimension of EQ-5D as well as EQ-5D index score (utility) were calculated. Results: Our findings indicated that the most frequent reported problems were pain/discomfort (67.8%) followed by anxiety/depression (57.5%). The mean of EQ-5D VAS was 75.8 (SD=17.0). The mean (SD) utility scores were 0.85 (0.19), 0.76 (0.20), 0.71 (0.21), and 0.77 (0.13) for cervical cancer patients in stage I, II, III, and IV, respectively. Conclusions: Cervical cancer significantly affects patient HRQOL. Efforts should be made to improve the quality of life of cervical cancer patients especially in terms of pain /discomfort and anxiety/depression reduction.

Background: Since the survival rate of breast cancer patients has improved, harmful effects of new treatment modalities on fertility of the young breast cancer patients has become a focus of attention. This study aimed to systematically review and critically appraise all available guidelines for fertility preservation in young breast cancer patients. Materials and Methods: Major citation databases were searched for treatment guidelines. Experts from relevant disciplines appraised the available guidelines. The AGREE II Instrument that includes 23 criteria in seven domains (scope and purpose of the guidelines, stakeholder involvement, rigor of development, clarity, applicability, editorial independence, and overall quality) was used to apprise and score the guidelines. Results: The search strategy retrieved 2,606 citations; 72 were considered for full-text screening and seven guidelines were included in the study. There was variability in the scores assigned to different domains among the guidelines. ASCO (2013), with an overall score of 68.0%, had the highest score, and St Gallen, with an overall score of 24.7%, had the lowest scores among the guidelines. Conclusions: With the promising survival rate among breast cancer patients, more attention should be given to include specific fertility preservation recommendations for young breast cancer patients.
