Bile juice prevents deposition of cholesterol in the blood vessel, digests fat, and absorbs fatty acid and vitamins, and it plays a great role on metabolism. Recently, emotional stimulus and mentally over-depression cause a person to come to illness, and westernization of way of life makes more patients with cholelithiasis, resulting into without bile secretion after cholelithotomy. Ageing, and gastrectomy and kidney transplantation are also the causes of more cholelithiasis occurrences. To solve these medical problems, we studied how Fel Sus Scrofa, which is not different from human bile juice, was used in the traditional Korean medicine. We I researched flavor, property, efficacy of Fel Sus Scrofa and how it was used by folk medicine, and we studied the usage examples of Fel Sus Scrofa in Sanghanlon and Dongeuibogam. The property of Sus Scrofa is bitter and cold. Its efficacy is to deposit glycogen. So it is known that it has been widely used, with many edible forms, without any humoral loss, for the inflammatory disease from various fever, problems of urine and feces, cutaneous disease, pulmonary disease, opthalmopathy, fever, thirst from diabetes, hepatocystic duct disorder. Fel Sus Scrofa can be used internally and externally to prevent humoral loss, and to control cutaneous disease among various pediatric disorder full of fever. And as we have in mind that it also can be used to treat patients with cholestasis after cholecystectomy, it is expected that post study of it must be done.

Iron deficiency anemia is also recognized as a serious disorder in many livestock, especially, piglets. We previously studied that the iron-fortified yeast (Saccharomyces cerevisiae) producing Sus scrofa ferritin heavy-chain (FER) was bioavailable to mice with iron deficiency. In this study, we determined whether FER could improve iron deficiency in piglets. The bioavailability of FER was examined by measuring body weight gain, hemoglobin concentration and hematocrit value in suckling and weaning piglets. We found that FER significantly increased hemoglobin value and the hematocrit ratio in suckling piglets (P<0.05). Furthermore, FER treatment significantly enhanced body weight gain in both groups of the suckling and weaning piglets (P<0.05). These results suggest that the iron-fortified recombinant yeast strain is helpful in iron absorption in piglets.

Fecal samples obtained from wild boar habitats are useful for the surveillance of diseases in wild boar populations; however, it is difficult to determine the species of origin of feces collected in natural habitats. In this study, a fecal IgA ELISA was evaluated as a method for identifying the porcine species from fecal samples. Both domestic pigs (Sus scrofa domestica) and wild boars (Sus scrofa coreanus) showed significantly higher levels of fecal IgA than other animal species. Additionally, age dependent changes in the level of Ig A in wild boars and domestic pigs were identified; Titers of Ig A were highest in suckling period and lowest in weanling period.

돼지 Duroc 품종의 mitochondria DNA D-loop전체 유전자를 증폭하기 위하여 많은 동물에서 고도로 상동성이 높은 tRNA-Pro와 tRNA-Phe 염기서열 일부를 이용하여 oligonucleotide primer를 제작하였다. 그 결과 Duroc 품종의 D-loop 전체 유전자는 1,145 base pairs 였으며, 그 중간위치에 10bp의 Sus Scrofa-specific sequence (TACACGTGCG)가 10개 존재하고 있었다. 돌연변이 검출을 위하여 가장 변이가 심한 지역을 primer 제작하여 345 bp의 DNA 단편을 증폭하였으며, Single Stranded Conformation Polymorphism(SSCP) 분석은 8% polyacrylamide gel에서 200 V, 16시간 전기영동하여 ethidium bromide (EtBr)로 10분간 염색하여 UV image analyzer로 관찰하였다. 그 결과 두 개의 서로 다른 밴드유형을 관찰하였으며, 21개 부위에서 염기서열 변이가 관찰되었다. 이러한 결과는 유전적 다양성 변이를 검출하는데 SSCP 분석이 유용한 도구라고 사료된다.

In this study, we produced iron-fortified yeast (Saccharomyces cerevisiae) producing Sus scrofa ferritin heavy-chain to provide iron supplementation in anemic piglets. We determined whether iron-ferritin accumulated in recombinant yeasts could improve iron deficiency in mice. C57BL/6 male mice exposed to Fe-deficient diet for 2 weeks were given a single dose of ferrous ammonium sulfate (FAS), ferritin-producing recombinant yeast (APO), or APO reacted with iron ($Fe^{2+}$) (FER). The bioavailability of recombinant yeasts was examined by measuring body weight gain, hemoglobin concentration and hematocrit value 1 week later. In addition, ferritin protein levels were evaluated by western blot analysis and iron stores in tissues were measured by inductively coupled plasma spectrometer. We found that anemic mice treated with FER exhibited increased levels of ferritin heavy-chain in spleen and liver. Consistently, this treatment restored the iron concentration in these tissues. In addition, this treatment significantly increased hemoglobin value and the hematocrit ratio. Furthermore, FER treatment significantly enhanced body weight gain. These results suggest that the iron-fortified recombinant yeast strain is bioavailable.

To know the status of sparganum (plerocercoid of Spirometra erinacei) infection in the Korean wild life, several species of wild animals were captured in Gangwon-do and examined for their status of infection with spargana. From February to December 2011, a total of 62 wild boars, 5 badgers, 1 weasel, 1 Siberian chipmunk, and 53 wild rodents were captured, and their whole muscles were examined with naked eyes for the presence of spargana worms. From the weasel and 1 wild boar, a total of 5 spargana specimens were extracted. The weasel was for the first time recorded as an intermediate or paratenic/transport host of S. erinacei in Korea, and both the weasel (Mustela sibirica manchurica) and wild boar (Sus scrofa) were added to the list of wild animals carrying spargana.

Background: Korean wild boars (Sus scrofa coreanus Heude), because of their adaptability, are a widespread large mammal; however, they sometimes cause problems by invading farms and eating the crops, creating insufficiencies of some foods in South Korea. To understand the diet composition of Korean wild boars according to sex and body size, we collected their feces from Mt. Jeombongsan, Seoraksan National Park, South Korea. The sizes of fecal samples were measured, and genomic DNA was extracted from the samples. We amplified specific loci targeting plants (rbcL and trnL) and animals (COI) to detect the food sources of this omnivore and amplified the ZF and SRY regions to determine the sex. Results: In the wild boar feces, Rosaceae and Bryophyte were the most frequently detected plant food sources at the family level and Diptera and Haplotaxida were the most frequently detected animal food sources at the order level. As a result of sex determination, the sex ratio of wild boars collected in the Mt. Jeombongsan area was approximately 1:1. Our result suggested that there is no significant difference between the diet composition of male and female boars. Based on the average cross-sectional area of the feces, the top 25% were classified into the large body size group and the bottom 25% were classified into the small body size group. The large body size group mainly preferred Actinidiaceae, and the small body size group most frequently consumed Fagaceae. The diet of the large body size group was more diverse than the small body size group. Conclusions: Our results showed that the wild boars preferred Rosaceae, especially Sanguisorba and Filipendula, as plant food sources, and Diptera and Coleoptera of Insecta as animal food sources. Based on the results, the dietary preferences of wild boar appear to be distinguished by not their sex but their body size. Our study could help to elucidate the feeding ecology and population structure of wild boar, as well as address conservation and management issues.

본 연구는 비침습 샘플인 털을 이용하여 영월 한반도습지 내 서식하는 멧돼지(Sus scrofa)의 유전분석을 통하여 그들의 서식 생태를 유추하였다. 털 시료는 2018년 11월부터 2019년 5월까지 한반도습지(2.772㎢) 내에서 비빔목 및 헤어트랩을 이용하여 수집하였다. 털 시료로부터 DNA를 추출하여 개체의 종과 성을 PCR을 통해 파악하였으며 6개의 마이크로새틀라이트 마커를 이용하여 개체 구분과 개체 간 유전적 근연관계를 유추하였다. 수집된 털 시료 중 총 16개의 털이 멧돼지의 시료였으며, 이는 암컷 7마리, 수컷 3마리의 10개체로부터 수집된 것임이 판명되었다. 이 10개체의 유전적 관계를 추정해 본 결과, 이들이 만들어내는 45쌍 중에 9쌍의 개체가 친족관계일 가능성이 높게 나타났다. 개체 쌍의 친족관계와 털 시료가 채집된 위치를 함께 고려하여 본 결과, 한반도습지 일대에서 서식하는 멧돼지는 암컷과 그 자손으로써 모계 가족단위로 생활하는 것으로 추정되며, 이는 기존에 알려진 멧돼지의 습성과도 일치하는 결과이다. 그러나 본 연구에 사용된 샘플과 마이크로새틀라이트 마커의 수가 제한적이므로 향후 추가적인 분석이 필요하다.
