The immune-stimulating activities of Bordetella bronchiseptica antigens containing dermonecrotoxin (BBD) loaded in chitosan microspheres (CMs) have already been reported in vitro and in vivo with a mouse alveolar macrophage cell line (RAW264.7) and mice. Therefore, this study attempted to demonstrate the successful induction of mucosal immune responses after the intranasal administration of BBD loaded in CMs (BBD-CMs) in colostrum-deprived pigs. The BBD was introduced to the CMs using an ionic gelation process involving tripolyphosphate (TPP). Colostrum-deprived pigs were then directly immunized through intranasal administration of the BBD-CMs. A challenge with a field isolate of B. bronchiseptica was performed ten days following the final immunization. The BBD-specific IgG and IgA titers, evident in the nasal wash and serum from the vaccinated pigs, increased with time (p<0.05). Following the challenge, the clinical signs of infection were about 6-fold lower in the vaccinated pigs compared with the nonvaccinated pigs. The grades for gross morphological changes in the turbinate bones from the vaccinated pigs were also significantly lower than the grades recorded for the nonvaccinated pigs (p<0.001). Therefore, the mucosal and systemic immune responses induced in the current study would seem to indicate that the intranasal administration of BBD-CMs may be an effective vaccine against atrophic rhinitis in pigs.

In this study, we analyzed the use of general radiography imaging and effective dose in inpatients. Our aim is to help reduce national medical radiation exposure doses and develop rational health-care financial policies. The effective dose for each general radiography was calculated using the ALARA-GR program for 53 types (total: 260 codes) general radiography codes selected from 'National Health Insurance Care Benefit Cost'. The usage of general radiography was analyzed in the 2018 inpatient patient data of the Health Insurance Review and Assessment Service, and the effective dose for each general radiography was analyzed. 89.00% of inpatients undergo general radiography imaging at least once, with an average of 12.63 scans per person and an effective dose of 1.00 mSv. Those who received support from Medical Aid showed a higher value compared to those who were insured by National Health Insurance, with 17.39 cases and 1.43 mSv (p<.001). Chest had the highest usage rate at 23.12% for general radiography imaging, while L-spine had the highest effective dose at 24.53%. It is estimated that 420 inpatients patients undergo 121 to 820 general radiography imaging procedures per year, and 233 inpatients are estimated to have an annual effective dose of >20.00~58.25 mSv. Rational use of health-care finances and the practice of medical radiation safety management are essential for the well-being of individuals, the enhancement of quality of life, and the improvement of health-care quality.

Vaccines are products for immunization which can provoke antibodies by eliciting immune reponses without causing disease and have played an important role in preventing fatal and contagious diseases as well as H1N1 influenza. They are classified by two following categories; lived attenuated vaccine and killed vaccine and currently commonly using vaccines are BCG, diphtheria, tetanus, mumps, measles, rubella, polio, Haemophilus influenza type b, hepatitis B, influenza etc. All vaccines must be used correctly to reach optimal therapeutic goals and also informed well to patients to decrease potential problems. In order to do, pharmacists must have good knowledge of vaccines. The purpose of this study is to evaluate the necessity of vaccine education for pharmacists and develop a vaccine leaflet for patient counseling. We have performed a survey with questionnaire for a total of 176 pharmacists and nurses(hospital pharmacists, n=65; community pharmacists, n=50; hospital nurses, n=61) from January 27th to March 12th, 2010. The questionnaire includes items about vaccine education and counseling and 12 quizzes to evaluate responders' knowledge of vaccines. We used the SPSS(Version 12. for windows) program to analyze the data. In results, 94.9% of all responders said they had not been educated on vaccines. And only 1.1% of all responders said they know about vaccines enough to counsel patients. Pharmacists who have an experience recommending vaccines to other people are 21.7%. On the other hand, nurses who have an experience recommending vaccines to other people are 55.7%(p=0.000). The mean number of correct answers at the 12 quizzes are followings; hospital pharmacist, 8.1; community pharmacist, 6.1, hospital nurses, 6.2(p=0.000). A vaccine leaflet for patient counseling is developed with several references. In conclusion, due to no opportunity of vaccine education, pharmacists have no confidence to counsel patients and lack of knowledge of vaccine. But importance of vaccine's role is increasing, pharmacists should counsel patients in vaccination. So they need vaccine education and a vaccine leaflet will be helpful for their counseling.

Cervical cancer (CaCx) is the second most fatal cancer contributing to 14% of cancers in Indian females, which account for 25.4% and 26.5% of the global burden of CaCx prevalence and mortality, respectively. Persistent infection with high-risk human papilloma virus (HPV- strains 16 and 18) is the most important risk factor for precursors of invasive CaCx. Comprehensive prevention strategies for CaCx should include screening and HPV vaccination. Three screening modalities for CaCx are cytology, visual inspection with acetic acid, and HPV testing. There is no Indian national policy on CaCx prevention, and screening of asymptomatic females against CaCx is practically non-existent. HPV vaccines can make a major breakthrough in the control of CaCx in India which has high disease load and no organized screening program. Despite the Indian Government's effort to introduce HPV vaccination in the National Immunization Program and bring down vaccine cost, challenges to implementing vaccination in India are strong such as: inadequate epidemiological evidence for disease prioritization, duration of vaccine use, parental attitudes, and vaccine acceptance. This paper reviews the current epidemiology of CaCx and HPV in India, and the current status of HPV vaccination in the country. This article stresses the need for more research in the Indian context, to evaluate interventions for CaCx and assess their applicability, success, scalability and sustainability within the constraints of the Indian health care system.

Arthritis is a common disease in aged people, and is clinically divided into rheumatoid arthritis (RA) and osteoarthritis (OA). Although common symptoms such as pain are present, the underlying pathological mechanisms are slightly different. Therefore, the objectives of the present study were to compare joint damage induced by RA and OA by analyzing the major morphological and molecular differences, and to propose a suitable therapeutic intervention based on the pathophysiological conditions of bones and joints. For the RA animal model, 8-week-old DBA1/J mice were immunized with bovine type II collagen emulsified in complete Freund's adjuvant (CFA). Normal C57BL/6 mice (over 2 years of age) were used for OA. The clinical arthritis score was calculated using a subjective scoring system, and paw thicknesses were measured using calipers. The serum TNF ${\alpha}$ level was analyzed using an ELISA kit. Micro-CT was used to identify pathological characteristics and morphological changes. In collagen-induced RA mice, there were increased ankle joint volumes and clinical scores (p<0.01). The concentration of TNF ${\alpha}$ was significantly increased from 3 to 7 weeks after immunization. Micro-CT images showed trabecular bone destruction, pannus formation, and subchondral region destruction in RA mice. OA among aged mice showed narrowed joint spaces and breakdown of articular cartilage. This study suggests that a careful therapeutic intervention between RA and OA is required, and it should be based on morphological alteration of bone and joint.

This study aims to provide basic data for elderly health insurance policy and medical radiation safety management by analyzing the general radiography usage and exposure dose of the elderly in Korea. The effective dose for each general radiography was calculated using the ALARA-GR program for 260 general radiography codes selected from 'National Health Insurance Care Benefit Cost'. The usage of general radiography was analyzed in the 2016 elderly patient data of the Health Insurance Review and Assessment Service, and the effective dose for each general radiography was applied. The general radiography usage and exposure dose per person aged 65 years and over was 6.47 cases and 0.56 mSv. Females showed higher value than males as 7.15 cases and 0.66 mSv(p<.001). By age, those between 75 and 79 showed the highest number as 6.97 cases and 0.62 mSv(p<.001). Those who were supported by Medical Aid showed higher value than those who were insured by National Health Insurance as 8.82 cases and 0.76 mSv(p<.001). In addition, the ratio by radiography was in the order of Chest 20.85%, Knee Joint 15.58%, and L-spine 14.67%, and the exposure dose was L-spine 29.40%, Chest 15.82%, Abdomen 7.97%, and Entire Spine 7.20%. General radiography, which is widely used due to the high frequency of diseases in the elderly population should be taken into consideration when establishing health insurance policies. In addition, it is necessary to check whether the general radiography with high exposure dose is performed as a routine examination without considering medical necessity.

Objectives: To evaluate the learning achievement and satisfaction levels for the Field Epidemiology Specialist Training Program (FESTP), on infectious disease control between March 19 and October 31, 2002. Methods : The FESTP was designed as a set of 84 hours curricula including lectures, discussions, self-studies, and field practicals, and organized both centrally and locally by the Division of Communicable Disease Control of the National Institute of Health and 11 universities. Before and after the program, a questionnaire survey on the educational need (49 items) and satisfaction (15 items) was conducted on 484 trainees, who were responsible for communicable disease control and immunization at 242 regional health centers. The data were analyzed with paired t-tests for comparison of the educational needs between the pre and post scores. Results : The average score for satisfaction was 3.06 out of 5.0; with relatively higher scores for sincerity (4.10) and professionalism (4.01) of the tutors, adequacy (3.54) and clearness (3.51) of the evaluation criteria, usefulness (3.54) and fitness (3.52) of the contents, but with relatively lower satisfaction for schedule (2.96) and self-studies (2.91). The average for requirement for education improved, as shown by the decrease from 2.72 to 2.22 (p<.0001) with the biggest decrease in the outbreak investigation from 2.60 to 2.08. Conclusion : The FESTP was evaluated as being effective, the trainees showed moderate satisfaction and decrease educational needs. However, the actual schedules and self-studies should be rearranged to improve the satisfaction level.

Background: HPV related cervical cancer as one of the most common women cancers in developing countries. Regarding accessibility of commercial vaccines, any long or short term modality for integrating preventive immunization against HPV in a national program needs comprehensive information about HPV prevalence and its genotypes. The important role of selecting most accurate diagnostic technologies for obtaining relevant data is underlined by different assays proposed in the literature. The main objective of the present study was to introduce an in-house HPV typing assay using multiplex real time PCR with reliable results and affordable cost for molecular epidemiology surveys and diagnosis. MATERIALS AND METHODS: 112 samples of formalin fixed paraffin embedded tissues and liquid based cytology specimens from patients with known different grades of cervical dysplasia and invasive cancer, were examined by this method and the result were verified by WHO HPV LabNet proficiency program in 2013. RESULTS: HPV was detected in 105 (93.7%) out of 112 samples. The dominant types were HPV 18 (61.6%) and HPV 16 (42.9%). Among the mixed genotypes, HPV 16 and 18 in combination were seen in 12.4% of specimens. CONCLUSIONS: According to acceptable performance, easy access to primers, probes and other consumables, affordable cost per test, this method can be used as a diagnostic assay in molecular laboratories and for further planning of cervical carcinoma prevention programs.
