  • 본 연구의 목적은 해산어류와 갑각류에 심각한 위해를 끼치고 있는 V. harveyi에 대한 백신개발을 위하여 V. harveyi 백신생산에 적합한 배양배지를 탐색하고 적정 투여량을 조사하며 또한 S. parauberis 백신과 혼합백신의 형태로 투여시 백신효능에 대해 조사하는 것이다. 이를 위하여 2-2'-dipyridyl이 첨가되거나 첨가되지 않은 TSB와 BHIB에 배양 후 FKC 백신을 제작한 후 넙치에 투여하여 응집항체가의 생산변화와 공격실험에서의 상대생존율을 비교분석하였다. 또한 V. harveyi 백신의 적정 투여량을 정하기 위하여 어체중 kg 당 10mg 또는 20mg을 투여하여 면역반응을 비교하였으며 S. parauberis 백신을 혼합한 백신을 투여한 후 면역반응을 비교하였다. 그 결과 2-2'-dipyridyl이 들어간 TSB와 BHIB에 배양된 V. harveyi 백신은 응집항체형성과 방어력에서 차이를 보이지 않았다. 또한 백신 투여량에 따른 응집항체가에 있어서 큰 차이는 없었으나 어체중 kg 당 10mg을 투여한 실험구가 조금 높은 방어력을 나타내었다. S. parauberis 백신과 혼합한 dual 백신을 투여시 V. harveyi 백신만을 단독으로 투여했을 때와 비교해 방어력이 현저히 증가하였으며 특히 어체중 kg당 두가지 백신을 각각 10mg씩 혼합하여 투여한 실험구에서는 28일동안 폐사가 전혀 일어나지 않아 백신효능이 매우 뛰어난 것으로 나타났다. 결론적으로 넙치를 위한 V. harveyi 백신을 개발할 때는 2-2'-dipyridyl가 첨가된 TSB에 배양 후 제작된 V. harveyi 백신을 어체중 kg당 10mg의 투여량으로서 S. parauberis 백신과 혼합투여하는 것이 효능과 경제적인 면에서 바람직하다고 생각된다.

  • The subacute toxicity of the combined vaccine (KGCC-95VI) for the prophylaxis against Japanese encephalitis and Hantaan virus infection, recently developed by Korea Green Cross Corporation, was investigated. KGCC-95VI was subcutaneously administered into the both sexes of New Zealand White rabbits at the dosage of 0, 10. 50 and 250 ml/kg body weight (20, 100 and 500 times the expected clincal dose) once a day for 30 days. There were no deaths and clinical findings during the experiment period. In both sexes. there were no statistically significant differences between the treated and control groups in urinalysis tests, hematological tests, blood chemistry tests and pathological examinations. The KGCC-95VI is considered not to have the subacute toxicity in the rabbits.

  • We have investigated efficiency of a recombinant subunit Pasteurella multocida toxin (PMT) that was mixed with a vaccine consisted of inactivated whole cells of Bordetella bronchiseptica, P. multocida (types A and D). For verification of the efficacy of the vaccine, all experimental pigs (suckling piglets, sow and gilts) in the three farms were vaccinated. Antibody titers against B. bronchiseptica and P. multocida type A of the vaccinated pigs by microplate agglutination were significantly higher than those of the control pigs (p < 0.05). Similar patterns were observed in the analysis of anti- PMT neutralizing antibody by serum neutralizing method using Vero cell (p < 0.05). Anti- P. multocida type D antibody titer of the vaccinated sows and gilts by ELISA showed significant differences with those of the non-vaccinated pigs (p < 0.05). Although antibody titers increased, it was unable to find out the difference in the clinical signs between the vaccinated and non-vaccinated pigs. However, the increase in body weight of the vaccinated piglets was observed in comparison with the non-vaccinated piglets on a farm. At slaughtering of the pigs, pathological lesions in the turbinate bones of the vaccinated pigs were significantly lower than those of the non-vaccinated pigs (p < 0.001). These results suggested that efficacy of the vaccine in pigs demonstrated to protect against atrophic rhinitis in Korea.

  • Carcinoembryonic antigen (CEA)는 다양한 종양에서 발현되는 자가 항원으로 면역치료에서 강력한 표지 인자이며 면역치료를 위한 표적 종양항원으로 널리 알려져 있다. 그러나 수지상세포 단독 치료는 동물모델에서 종양의 발생을 억제하는 데 효과가 있지만 이미 확립된 종양을 제거하는 데는 한계가 있다. 본 연구에서는 항종양 면역 효과를 증가시키기 위하여 화학치료제인 cyclophosphamide (CYP)와 종양 특이 면역치료법인 수지상세포 백신의 병합치료 효과를 CEA를 발현하는 마우스 종양 모델에서 검증하였다. 종양세포 주입 후 2일 소종양군과 10일 대종양군에서 CYP의 항종양 효과를 비교한 결과, 소종양군에서는 100 mg/kg에서 뚜렷한 종양 성장의 억제 효과가 관찰되었지만 대종양군에서는 약한 억제 효과가 관찰되어 본 연구에서는 대종양군을 병합치료의 적합한 모델로 설정하였다. CYP 와 수지상세포 백신의 병합치료(화학면역치료) 시 종양항원 특이 면역반응이 증가되었을 뿐만 아니라 상승적인 항종양 효과가 나타났다. 또한 CYP 치료에서 나타나는 체중 감소 및 조절 T세포와 골수유래 억제세포의 증가에 의한 면역억제는 화학면역치료에 의해 개선되었다. 항원 특이 면역치료를 병합한 화학면역치료가 화학치료의 부작용을 감소시키고 항종양 효과를 증가시킬 수 있는 치료 전략이 될 수 있을 것이다.

  • Due to the fact that an inactivated anthrax vaccine may lark its immunogenicity and stability of immunogen a number of spore vaccines were exclusively used worldwide. In these studies a number of important factors were emphasized to achieve the following: selection of non or less allergic strain of anthrax bacillus, capsulation of bacteria. obtaining of non sporulating but vegetative organisms, adequate inactivation of B. anthraccis by means of formalin, adsorption of immunogen to aluminum hydroxide gel. Non or less allergic strains of anthrax bacillus which is inactivated with formalin was selected by a hyperimmunization and shock test in rabbits. Obtaining capsular material and vegetative immunogen, a virulent anthrax organisms were cultivated on sodium bicarbonate medium with of without adding of l-alanine in which B, anthracis grew luxuriantly without forming spores. Inactivation was carried out at $37^{\circ}C$ water bath for 3 days after the bacterial culture was mixed with formalin, in a final concentration of two per cent of formalin. Aluminum hydroxide gel was added to the mixture of anthrax and blackleg bacterin. Vaccines were injected guinea pig via subcutaneous or intramusoular route and challenged after three weeks and the possibilities of protection was tested. Throughout the studies. the above mentioned vaccines possibly protected the vaccinated guinea pigs more than 80 per cent compared to that of the controls. This experimental results strongly suggest that the vaccine may possibly applicable to bovine.

  • In many countries, vaccines are used for the prevention of foot-and-mouth disease (FMD). However, because there is no protection against FMD immediately after vaccination, research and development on antiviral agents is being conducted to induce protection until immunological competence is produced. This study tested whether well-known chemicals used as RNA virus treatment agents had inhibitory effects on FMD viruses (FMDVs) and demonstrated that ribavirin showed antiviral effects against FMDV in vitro/in vivo. In addition, it was observed that combining the administration of the antiviral agents orally and complementary therapy with vaccines synergistically enhanced antiviral activity and preserved the survival rate and body weight in the experimental animals. Antiviral agents mixed with an adjuvant were inoculated intramuscularly along with the vaccines, thereby inhibiting virus replication after injection and verifying that it was possible to induce early protection against viral infection prior to immunity being achieved through the vaccine. Finally, pigs treated with antiviral agents and vaccines showed no clinical signs and had low virus excretion. Based on these results, it is expected that this combined approach could be a therapeutic and preventive treatment for early protection against FMD.

  • Today, social media has become a vital tool. The world communicates and reaches the news and each other's opinions through social media accounts. Recently, considerable research has been done on analyzing social media due to its rich data content. At the same time, since the beginning of the COVID-19 pandemic, which has afflicted so many around the world, the search for a vaccine has been intense. There have been many studies analyzing people's feelings during a crisis. This study aims to understand people's opinions about available Coronavirus vaccines through a learning model that was developed for this purpose. The dataset was collected using Twitter's streaming Application Programming Interface (API) , then combined with another dataset that had already been collected. The final dataset was cleaned, then analyzed using Python. Polarity and subjectivity functions were used to obtain the results. The results showed that most people had positive opinions toward vaccines in general and toward the Pfizer one. Our study should help governments and decision-makers dispel people's fears and discover new symptoms linked to those listed by the World Health Organization.

  • 목적 : 디프테리아, 파상풍, 백일해 및 불활화 폴리오 백신인 GlaxoSmithKline Biologicals의 $Infanrix^{TM}$-IPV(DTPa-IPV)를 접종시, 시판되고 있는 DTPa 백신과 IPV 백신을 각각 다른 부위에 동시 접종 했을 때(DTPa+IPV)와의 면역원성과 반응원성을 비교하기 위하여 본 연구를 시행하였다. 방법 : 생후 8-12주의 영아 458명을 무작위 배정하여, 각각 2, 4, 6개월에 DTPa-IPV 혹은 DTPa+IPV를 3회 기초접종 하였다. 면역반응을 확인하기 위하여 백신접종 전과 후에 채혈을 하였다. 반응원성은 각 백신 접종 후 작성된 증상기록카드를 통하여 평가하였다. 결과 : 3차 백신접종 한달 후에, 항-디프테리아, 항-파상풍 그리고 항-폴리오바이러스 type 1, 2, 3에 대한 혈청 방어율(seroprotection rate)은 ${\geq}99.5%$였고, 두군 모두 백일해 항원에 대한 백신 반응률(vaccine res-ponse rates)은 적어도 98.6% 이상이었다. 두 군간의 비 열등성은 사전 정의된 통계적 기준에 따라 보여주었다. 국소증상과 전신증상 발생률은 두 군 모두 비슷하게 보고되었고, grade 3의 증상이 DTPa-IPV 투여군에서 4.3%, DTPa+IPV 투여군에서는 4.5%로 보고되었다. 두 건의 중대한 이상반응(모두 발열)이 DTPa-IPV 투여 후에 보고되었고, 백신과의 연관성이 있는 것으로 간주되었다. 두 명의 영아는 모두 회복되었다. 결론 : DTPa-IPV 혼합백신은 한국의 소아들에게 기초접종으로 3회 투여시 충분한 면역반응을 보였고, 내약성이 우수했다. DTPa-IPV는 한국 예방접종 스케줄에 편입되어, 기초 접종을 완료하기 위한 접종 회수를 줄일 수 있다.
