국내산 수산물 내 자연 및 인공방사능 축적 연구 현황 및 향후 연구 방향

이희수,김인태,Lee, Huisu,Kim, Intae 해양환경안전학회 2021 해양환경안전학회지 Vol.27 No.5

2011년 동일본대지진에 의해 발생한 후쿠시마 원자력 발전소 사고와 최근 국내 지진 발생 빈도의 증가는 원자력 발전소의 지진 안전성에 대한 불안감을 야기하였다. 더불어 최근(2021년) 일본 동경전력은 후쿠시마 원전 오염수의 태평양 방류를 결정하였으며, 이로 인해 국내외 수산물을 통한 방사능 오염 가능성이 높아지면서 국민들의 우려가 급증하고 있다. 후쿠시마 원전사고 이후 해양으로의 인공방사능 유입에 관한 연구는 국제적으로 많이 이루어졌으나, 한국인의 주요 식재료인 동아시아 연근해의 수산물에서 인공방사능의 분포 현황 및 축적에 대한 연구는 상대적으로 부족한 실정이다. 따라서 이 논문에서는 후쿠시마 원전사고 이후, 국내산 수산물에서의 원전 기원 인공방사능(예, ¹³⁷Cs, ^239+240Pu, ⁹⁰Sr 등)의 분포 특성과 관련한 최근 연구 사례들을 소개하고자 한다. 또한, 후쿠시마 원전오염수의 방류와 더불어 2030년까지 계획된 중국의 신규 원전 시설로 인한 향후 한반도 주변해역의 방사능 유출 영향에 대한 대비 및 사전 연구가 필요한 시점이기에 향후 연구 방향들을 제안하고자 한다. The Fukushima nuclear power plant (NPP) accident caused by the East Japan Earthquake in 2011 and the recent increase in the frequency of earthquakes in Korea have caused safety concerns regarding radionuclide exposure. In addition, the Tokyo Electric Power Company (TEPCO) in Japan recently decided to release radionuclide-contaminated water from Fukushima's NPP into the Pacific Ocean, raising public concerns that the possibility of radionuclide contamination through both domestic- and foreign fishery products is increasing. Although many studies have been conducted on the input of artificial radionuclides into the Pacific after the Fukushima NPP accident, studies on the distribution and accumulation of artificial radionuclides in marine products from East Asia are lacking. Therefore, in this study, we attempted to explore recent research on the distribution of artificial radionuclides (e.g., ¹³⁷Cs, ^239+240Pu, ⁹⁰Sr, and etc.) in marine products from Korean seas after the Fukushima NPP accident. In addition, we also discuss future research directions as it is necessary to prepare for likely radiation accidents in the future around Korea associated with the new nuclear facilities planned by 2030 in China and owing to the discharge of radionuclide-contaminated water from the Fukushima NPP.

Fowl typhoid caused by Salmonella gallinarum has increased dramatically since 1992 and has caused a great economic losses in chicken industry by characterizing with high mortality. In these studies, we investigated the immunogenicity and protectivity in chickens which were immunized with outer membrane protein(OMP) extracted from isolates of S gallinarum against challenge with live microorganism. Outer membrane proteins were composed of various sizes of molecular weight including 14K, 22K, 31K, 36K, 40K and 55K and the most of them responded strongly against rabbit antisera in immunoblot analysis. The chickens vaccinated with OMP or vaccinated with whole-cell combined with OMP($200{\mu}g$/chickens) complex showed higher delayed type hypersensitivity(DTH) response than that of whole-cell vaccinated group. The protective rates of OMP or whole-cell combined with OMP complex group against challenge of S gallinarum were higher (above 75%) than those (45~50%) of whole-cell vaccinated group. All vaccines were safe and the body weight-gains of all vaccinated groups were not significantly different (p<0.05) from those of nonvaccinated control group. In vitro tests, OMP stimulated both the proliferation of lymphocytes and T-lymphocytes, and OMP-induced lymphocyte proliferation was higher in the cells of the immunized chickens with OMP than in those from the control chickens.

국내 분리주 Salmonella gallinarum의 닭에 대한 병원성

Fowl typhoid(FT) caused by Salmonella gallinarum is an infectious, egg-transmitted disease and characterized by swollen bronze liver, greenish-yellow diarrhea and high mortality in growing and adult chickens. Since 1992 the outbreak of FT has been increased. Several problems have been occurred such as absence of appropriate vaccines and lack of useful therapeutic methods. In these studies we investigated the pathogenicity of S gallinarum isolated in chickens. To compare the pathogenicity among the species of chickens, all chickens were challenged intramuscularly or orally with $1{\times}10^7$ CFU of S gallinarum. The brown-colored layers were more susceptible and white leghone chickens were more resistant than other species. In the brown layer chickens orally challenged, lethal doses ($LD_{50}$) of the isolates were inoculated at 1 day, 2 weeks, 4 weeks and 8 weeks old chickens with amount of $10^{4.2}$, $10^{4.7}$, $10^{7.0}$ and $10^{7.6}$ CFU, respectively. The chickens which were intramuscularly challenged with the less amount than $10^2$ CFU showed higher mortality than that of the chickens orally inoculated with same dose. Also, we investigated the recovery rates of bacteria from various organs of survival chickens which were challenged orally with $5{\times}l0^7$ CFU of S gallinarum. The bacteria was more frequently and isolated earlier from the liver and spleen than from any other ogans. In the pathogenicity test, the white-leghorn chickens which were known as resistant-strain against Salmonella were artificially immunosuppressed using bursectomy and/or dexamethasone treatment. Mortality of chickens with both bursectomized and treated with dexamethasone was higher(90%) than that of the control group(10%), the bursectomized chickens(10%) and the dexamethasone only treated group(20%). It was suggested that the protective mechanism in chickens against S gallinarum may be required both the functions of B-cells and T-cells.

Salmonellosis caused by a number of serotypes of Salmonella is an infectious, acute or chronic, zoonotic disease and characterized by enteritis and diarrhea, septicemia in animal. In these studies we investigated the prevalent serotypes of Salmonella causing animal salmonellosis in Korea and the 71 strains of Salmonella spp. were isolated from materials such as mesenteric lymph nodes, fecal samples from slaughtered animal. With the identification test results, the most prevalent serotypes were, in order, S stanley 31 strains (43.7%), S typhimurium 19 strains (26.8%) and S montevideo 11 strains (15.5%), respectively. And we could establish the method for detection of antibodies to broad variety of Salmonella serotypes. Lipopolysaccharide(LPS) antigen extracted from Salmonella was more sensitive and specific than outer membrane protein antigen from that for detection of Salmonella antibody by using an indirect ELISA. The optimal concentration of antigen was 100ng/ml of LPS, the dilutions of conjugate and serum were 1 : 1,000~2,000 and 1 : 200~400, respectively. The mix LPS-ELISA which was used by mixing LPS from S typhimurium (group B), S choleraesuis (group C) and S enteritidis (group D) were more rapid and effective than that used LPS from individual strain for detection of Salmonella serogroup O4, O7 and O9 antibody at the same time. We could obtain the high values of optical density ($0.73{\pm}0.32$) by mix LPS-ELISA on the farm which had occurred salmonellosis, but very low values of $0.17{\pm}0.06$ on the negative farm of salmonellosis. So, the mix LPS-ELISA may be used to monitor the serological surveillance for the presence of infection with a number of serotypes of Salmonella and would be useful for prevention and control of salmonellosis in animal.

소 세균성 폐렴과 예방대책

이희수,Lee, Hui-Su 한국단미사료협회 2006 피드저널 Vol.4 No.12

소에서 발생하는 호흡기 질병은 가축이 가지고 있는 내적인 요인과 사육환경의 악화나 각종 스트레스 등의 외적인 요인과의 복합적인 균형의 파괴에서 시작된다고 볼 수 있다. 이와 같은 질병발생요인은 다른 축종이나 소화기 등 타 질병에서도 동인한 사항으로 생각될 수 있으나 호흡기질병의 경우 환경적인 요인이 더욱 중요한 발병이자로 작용하게 된다. 즉 밀집다두사육, 환절기의 낮과 밤의 큰 일교차, 환기불량이나 우사내의 유해가스, 장거리 수송 등의 스트레스가 일차적인 발병인자가 되며, 이타적으로 가축이 가지고 있거나 외부에서 유입된 여러 가지의 병원 미생물의 다량증식하고, 동물개체는 면역력이 떨어지면서 질병에 감염되어 단일 또는 복합적인 임상증상으로 나타나는 것이다. 호흡기질병의 원인균에는 다양한 종류의 세균 및 바이러스에 의해 이루어지며, 단일의 원인균에 의한 질병발생보다는 복합적으로 감염되어 병을 악화시키고 피해를 크게 하는 것이 일반적이다. 본고에서는 소에서 흔히 나타날 수 있는 주요한 세균성 호흡기 질병의 종류와 임상증상 및 일반적인 방제대책에 대하여 기술하고자 한다.
