Purpose : The purpose of this study was to evaluate the types of lymphadenitis after BCG vaccination and the effect of local rifampicin instillation on the treatment of suppurative BCG lymphadenitis. Methods : A total of 32 otherwise healthy infants with suppurative BCG lymphadenitis, who visited the Department of Pediatrics of Chonbuk National University Hospital, from March 2002 through June 2004, were enrolled in this study. They were treated with needle aspiration and local rifampicin instillation. We investigated the time the lymphadenitis took to be suppurative, accompanying clinical manifestations, and the treatment effects. Results : Of the 32 infants, 19 were male and 13 were female. They were full term babies and one preterm baby with a gestational age of 30 weeks. They received intradermal administration, with the BCG vaccine of $Pasteur^{(R)}$(French) strain mostly on the left deltoid area(96.9 percent). Regional lymphadenitis occurred in 1 to 11 months after BCG vaccination, mostly 1-5 months after vaccination (78.1 percent). Among the infants, 87.5 percent had unilocular lesion but 12.5 percent had more than one enlarged lymph node cares. Most of the lymphadenitis presented in the left axillary area(77.8 percent), and the left supuraclavicular area(11.1 percent). After one to three times of needle aspiration with rifampin instillation, all infants recovered completely without surgical excision or severe complication. Conclusion : The regional lymphadenitis is the most common complication in infants who receive intradermal BCG vaccination. This study supports that in suppurative BCG lymphadenitis the needle aspiration and local rifampicin instillation is very effective and can be a more economical treatment modality.

Influenza viruses are zoonotic respiratory pathogens, and influenza infections have caused a substantial burden on public health systems and the livestock industry. Although currently approved seasonal influenza vaccines have shown potent protection efficacy against antigenically well-matched strains, there are considerable unmet needs for the efficient control of viral infections. Enormous efforts have been made to develop broadly protective universal influenza vaccines to tackle the huge levels of genetic diversity and variability of influenza viruses. In addition, antiviral drugs have been considered important interventions for the treatment of viral infections. The viral neuraminidase inhibitor oseltamivir is the most widely used antiviral medication to treat influenza A and influenza B viruses. However, unsatisfactory clinical outcomes resulting from side effects and the emergence of resistant variants have led to greater attention being paid to plants as a natural resource for anti-influenza drugs. In particular, the recent COVID-19 pandemic has underpinned the need for safe and effective antiviral drugs with a broad spectrum of antiviral activity to prevent the rapid spread of viruses among humans. This review outlines the results of the antiviral activities of various natural products isolated from plants against influenza viruses. Special focus is paid to the virucidal effects and the immune-enhancing effects of antiviral natural products, since the products have broad applications as inactivating agents for the preparation of inactivated vaccines and vaccine adjuvants.

Objectives: This study examined the effectiveness of Korean medical treatment for two patients complaining of discomfort after receiving Pfizer COVID-19 vaccine. Methods: The patients were hospitalized for 50 days and 12 days, respectively. They were treated with herbal medicine, acupuncture, electroacupuncture, and moxibustion. We used the Numerical Rating Scale (NRS) on numbness in extremities and headache, Manual Muscle Testing Grading System (MMT), Criteria for Sweating Categorization, and 36-Item Short Form Health Survey (SF-36) to evaluate the clinical effects of the treatment. Results: In Case 1, headache improved from peak NRS 9 and average NRS 7 on admission day to both NRS 3 on discharge. The SF-36 score was also increased, suggesting that the quality of life was improved. In Case 2, numbness in the extremities improved from NRS 8 on the day before admission to NRS 2 on discharge, and general condition also improved. Conclusions: This study suggests that Korean medicine can be an effective treatment for patients who experience long-lasting discomfort after being vaccinated with COVID-19, but with no abnormal findings in the examination.

Purpose : We investigated whether there had been any change in the epidemiology of Streptococcus pneumoniae in Korea before and after introduction of heptavalent pneumococcal conjugate vaccine(PCV7). Methods : Between September 2001 and August 2006, clinical isolates were collected from patients with pneumococcal infection in Severance Hospital, Seoul, Korea. We analyzed trends in serotype distribution and antibiotic resistance before and after the introduction of PCV7. Results : There were 363 strains of Streptococcus pneumoniae isolated from clinical specimens; 143 before and 220 after PCV7 introduction. The predominant serotypes, in order of decreasing frequency, were 19F, 19A, 23F, 6B, 6A, 3, 9V, 14, 11A, 4, 29, and 18C; 152 isolates(41.9%) belonged to types included in PCV7. The proportion of clinical isolates that were nonsusceptible to penicillin increased from 58.8% in 2001 to 83.6% in 2006(P=0.046). There was no significant diminution in pneumococcal infection caused by vaccine serotypes after the introduction of PCV7. In children younger than age 2 years, the proportion of clinical isolates that were vaccine serotypes was higher than in persons older than age 15 years (59.3% vs 37.8%, P=0.004). Conclusions : There was no significant diminution in pneumococcal infection caused by vaccine serotypes after the introduction of PCV7, therefore more universal pneumococcal immunization program is recommended especially for children younger than age 2 years.

Purpose: This study was conducted to investigate the factors predicting HPV (Human Papilloma Virus) vaccination practices among female college students. Methods: A convenience sample of 207 female students attending four universities in one metropolitan city participated. Self-report questionnaires consisted of general characteristics, characteristics related prevention of cervical cancer, knowledge of HPV, knowledge of cervical cancer vaccination, and health beliefs related to HPV vaccination. Data were analyzed by $x^2$ test, independent t-test, and bivariate logistic regression. Results: Factors predicting HPV vaccination practices were information about HPV (OR=3.37), experience of HPV test (OR=12.71), and health beliefs related to HPV vaccination (OR=1.13). Conclusion: In order to increase the practice rate of HPV vaccination, it is necessary to provide simple key information that is easy to understand, rather than expert knowledge about HPV. Therefore, it is necessary to provide a way for college students to get information about virus easily. It is necessary to intervene integrally with the facilitation factor and obstacle factor of vaccination practice.

Purpose : Yellow fever, a mosquito-borne viral hemorrhagic fever, is one of the most lethal diseases. Recently there have been an increasing number of Korean children who have travelled to yellow fever endemic zones and were administered yellow fever vaccine (YFV). Therefore, we carried out this study to provide child travelers with safety information of YFV. Methods : This study was conducted at the International Clinic of National Medical Center in Seoul between April 2007 and June 2008 for the evaluation of adverse events of YFV. One hundred twenty-five children received YFV (17-DD) and were prospectively monitored for adverse events through telephone interviews on day 3, 6, 9, 16, 23 and 30 after vaccination. Results : Adverse events were observed in 31 (24.8%) of 125 child travelers who received the YFV. The mean age was 12.5${\pm}$5.0 years. Sixty-six of the child travelers (52.8%) were males. The common adverse events were pain in 11 (8.8%), swelling in 8 (6.4%) and redness in 7 children (5.6%) at the injection site. The systemic adverse events included mild fever in 5 (4.0%), headache in 5 (4.0%), cough in 4 (3.2%), abdominal pain in 3 (2.4%), and vomiting in 2 children (1.6%). Most of the adverse events were detected within 7 days of administration and there were no differences in adverse events by gender or age. All travelers who had complained of symptoms improved spontaneously or following symptomatic treatment. Conclusion : This study showed that YFV is well-tolerated and there were no reports of severe adverse events. Studies are ongoing to clarify the cause and risk factors for rare adverse events.

산란계 경영에 있어서 실제 사업의 처음이 초생추 또는 중추의 입식이라면 노계도태는 그 끝이라고 할 수 있다. 계사를 청소하고 소독을 한 후 입추시기와 품종 등을 신중히 고려해 병아리를 입식하고 각종 백신을 접종하고 세심하게 길러내어 성계로 만들어 놓고 갖은 질병의 지뢰밭을 통과하면서 최대한으로 계란을 낳게 하다보면 어느덧 우리의 알 기계는 노후되어 도태시기를 결정하게 된다. 필자는 지난 15년간 고창양계라는 부화장에 근무하면서 주로 병아리 판매업무에 종사하면서 전국의 사양가분들과 접촉해온 경험이 있는 바, 대부분의 농장주들이 마지막 단계인 이 노계도태를 단순히 병아리를 새로 받기 위해 즉흥적으로 그 시기를 결정하거나, 거꾸로 노계를 도태한 후 서둘러 신규입추를 추진하는 등 실로 비합리적인 경우가 너무 많았음을 기억하면서 이번 기회를 통해 노계도태의 모든 부분을 정리해 보고자 한다.

큰 일교차는 가축면역력 약화를 부른다. 낮과 밤의 일교차 약 $10^{\circ}C$ 전후의 환절기에는 면역력이 약한 어린 가축은 환경의 변화에 따른 대사불균형으로 질병 발생률이 높아진다. 가축에게 환경 스트레스를 낮춰주기 위해 아침 저녁으로 바깥의 찬공기에 노출되지 않도록 차단해야 하고 야간에는 축사보온, 낮에는 환기가 충분히 이루어지도록 해야 한다. 또한 양질의 사료공급은 물론 비타민, 광물질 등의 첨가제를 적절히 배합해 급여하고 호흡기 질병 및 설사병 등의 백신을 적기에 접종해 면역능력을 가질 수 있도록 해야 한다.
