  • Bovine respiratory syncytial virus (BRSV) and bovine viral diarrhea virus (BVDV) are the main viral contributors to bovine respiratory disease (BRD) with high mortality and morbidity. BRD control measures include vaccination that modulates immunological profiles reflected in blood cells, serum, and body secretions, such as milk. This study evaluated the immune responses to an inactivated BRD vaccine in lactating cows reared in a natural environment on a dairy farm. The cows were intramuscularly inoculated with the vaccine, and serum, blood, and milk were collected pre-and post-vaccination. Our study revealed a prominent increase in BRSV-specific antibodies both in serum and milk, while the change in BVDV-specific antibodies was insignificant. Serum interleukin (IL)-1β and IL-6 levels significantly decreased, but this change was not reflected in milk. Evaluation of pattern recognition receptors (PRRs) via RT-qPCR revealed downregulation of nucleotide-binding oligomerization domain 2 (NOD2). The concentrations of BRSV antibodies, BVDV antibodies, IL-2, and IL-17A in serum and milk were strongly correlated, implying a concurrent influence on both body fluids. Thus, immunological factors modulated as a result of vaccination generally measured in serum were reflected in milk, demonstrating the suitability of milk evaluation as an alternative approach for immunological observations. Furthermore, the correlation between BRSV antibodies and NOD2 and that between BVDV antibodies and toll-like receptor (TLR) 2, TLR3, TLR4, and TLR5 imply the possible role of PRRs for the assessment of the immune response developed in immunized cows reared on the farm.

  • Purpose: Tuberculosis(TB) care unit in public health center should be carefully considered to be re-designed as an infection safety environment for both patient and healthcare workers. So, for the enhancement, this study analyses the facility requirements for co-using the screening clinic as a TB and other respiratory disease care unit. Methods: Not only screening clinic facility guidelines from "A Study for Standard Triage Design and Construction Document" but also the guidelines of TB care and related medical facility are reviewed; KDCA, CDC, ECDC and WHO as a TB care, and FGI and NHS for facility. The facility requirements are summarized space, approach, and mechanical requirement in order. By comparing the summary and screening clinic facility guidelines, supplementations are proposed for TB care unit setting. Results: The result of this study shows that both the space program and mechanical requirement of the screening clinic and that of TB care unit are almost identical and could be share, which include direct airflow or negative air pressure in an exam room. To increase functional and economical efficiency, however, it is necessary to consider a multi-functional negative pressured room, So care process may be re-designed based on a room type; face-to-face room or glass wall inbetween. Implications: The facility guidelines for TB care unit of a public health center should be developed to build a safe environment for infection control by reflecting its medical plan and budget.

  • Objectives : Sojadodamgangki-tang and its main components are traditional korean medicinal methods for treatment of cough, sputum and dyspnea. Using a respiratory inflammatory model, we intend to reveal the anti-inflammatory effect and its immune mechanism of Sojadodamgangki-tang. Methods : We used a papain-induced respiratory inflammatory mouse model. 8-week-old female BALB/C mice were divided into 3 groups as follows: the following groups: saline control group, papain treated group (vehicle), papain and Sojadodamgangki-tang(200 mg/kg) treated group (n=4). To evaluate the anti-inflammatory effect of Sojadodamgangki-tang extracts, inflammatory cell infiltration was measured in bronchoalveolar lavage fluid (BALF) and nasal lavage fluid (NALF). In addition, the effects of Sojadodamgangki-tang extracts on Th2 cell population in lung were determined by using flow cytometry. Results : Sojadodamgangki-tang extracts administration reduced inflammatory cell infiltration in BALF and NALF, especially of eosinophils. Furthermore, total immunogloblin (Ig)-E levels was reduced in BALF and serum by drug administration. Interestingly, Sojadodamgangki-tang extracts treatment also decreased the Th2 cell (CD4+GATA3+) population in lung. Conclusions : Our findings indicate Sojadodamgangki-tang extracts have anti-inflammatory effects by mediating Th2 cell and B cell activation.

  • Haepyoijin-tang and its main components have been used for phlegm, cough and dyspnea. Using a respiratory inflammation model, we intend to reveal the anti-inflammatory effect and pharmacological mechanism of Haepyoijin-tang. We induced the respiratory inflammation model by Aspergillus oryzae protease and ovalbumin administration. Female Balb/c mice (8 weeks old) were classified into four groups as follows: saline control group, aspergillus oryzae protease and ovalbumin induced respiratory inflammation group (vehicle), inflammation with Haepyoijin-tang (200 mg/kg) administration group, inflammation with dexamethasone (5 mg/kg) administration group (n=7). To identify the anti-inflammatory effects of Haepyoijin-tang water extracts, we measured the inflammatory cell number in bronchoalveolar lavage fluid (BALF) and total live lung cell number. In addition, we checked eosinophil ratio and number in BALF. And Interleukin (IL)-5 level was also measured in lung cell culture supernatant. To confirm the mechanism of anti-inflammatory effects, we analyzed the activated helper T cell (CD4+CD25+ cell) and Th2 cell (CD4+GATA3+ cell) ratio and number in lung by using flow cytometry. Finally, we attempted to confirm the immune mechanism by measuring the ratio and number of regulatory T cells (CD4+Foxp3+ cell). Haepyoijin-tang extracts treatment diminished inflammatory cell, especially, eosinophil number in BALF and total live lung cell number. Moreover, IL-5 level was reduced in Haepyoijin-tang treated group. Surprisingly, Haepyoijin-tang extracts administration not only decreased the activated helper T cell but also Th2 cell population in lung. Additionally, regulatory T cell population was increased in Haepyoijin-tang administration group. Our findings proved that Haepyoijin-tang extract have anti-inflammatory efficacy by suppressing Th2 cell activation and promoting regulatory T cell population.

  • Massive and untreated hemoptysis is associated with a mortality of greater than 50 percents. Since the bleeding was from a bronchial arterial source in the vast majority of patients, embolization of the bronchial arteries has become an accepted treatment in the management of massive hemoptysis because it achieves immediate control of the patients. We have controlled massive hemoptysis in a case with selective bronchial arteral embolization with Gelfoam.

  • Background: Detection and treatment of tuberculosis (TB) infection with contact investigation is a key component of TB control program. I evaluated the prevalence and risk factors for TB infection among contacts of recently diagnosed pulmonary TB patients in a tertiary hospital in Korea. Methods: 206 contacts of 90 adult pulmonary TB patients underwent tuberculin skin tests (TST) and chest radiography. The TST results were considered positive with an induration of 10 mm or more, suggesting TB infection. A standardized questionnaire was used to assess risk factors associated with TB infection. Results: TST was positive in 97 of 206 contacts of TB patients (47.1%) and positive rate of TST increased with age. The risk of TB infection was significantly associated with close contact with TB patients (sleeping in the same room) (odd ratio [OR], 4.94; 95% confidence interval [CI], 1.43~17.00). Conclusion: TB infection rate was higher in the elderly, and the risk of TB infection was significantly increased with close contact of TB patients.

  • Smoking is the most important risk factor of many pulmonary diseases, including chronic obstructive pulmonary disease and lung cancer, cardiovascular disorders and other malignancies. Therefore, smoking cessation is a practical way to prevent and treat smoking-related diseases. Also, the clinicians who care the patients with smoking-related disease should pay attention to it. This article reviews briefly recent publications focused on the influence of smoking cessation in some smoking-related diseases and strategies to improve smoking cessation such as pharmacotherapy or systemic behavioral approach programs. In addition, it reviews personalized therapy based on gene typing for smoking cessation.

  • Effects of Escherichia coli genomic DNA on the production of phagocyte activating supernatants by the head kidney leucocytes isolated from olive flounder (Paralichthys olivaceus) were investigated. Phagocyte activating activity of the supernatants was estimated by. measuring reactive oxygen species (ROS) production in target head kidney phagocytes. All supernatants from olive flounder head kidney leucocytes-stimulated with E. coli DNA induced significantly (P<0.01) higher ROS production from target pagocytes than the unstimulated control supernatant. Maximum enhancement of chemiluminescent response was observed $5.0-10.0{\mu}g\;mL^{-1}$ of bacterial DNA while the increment ability was decreased significantly (P<0.01) at the concentration of $20.0{\mu}mL^{-1}$. The results demonstrate that olive flounder head-kidney leucocytes stimulated with bacterial DNA release a soluble phagocyte activating cytokines capable of enhancing the respiratory burst activity from target phagocytes.

  • Controlling inappropriate antibiotics prescribing for acute upper respiratory infections(URI) is a very important for prudent use of antibiotics and resistance control. Health Insurance Review and Assessment Service (HIRA) introduced Prescribing Evaluation Program and publicly reported antibiotics prescribing rate for URI of each health institution. We performed segmented regression analysis of interrupted time series to estimate the effect of public report on antibiotics prescribing rate using national health insurance claims data. The results indicate that just before the public report period, clinics' monthly antibiotics prescribing rate for URI was 66.7%. Right after the public report, the estimated antibiotics prescribing rate dropped abruptly by 12.3%p. There was no significant changes in month-to-month trend in the prescribing rate before and after the intervention.
