  • The number of wild animal species is gradually decreasing due to poaching, hunting and habitat loss. While several endangered animal species have been successfully preserved at the zoo, assisted reproductive technology (ART) must be applied to restore wild animals. In the case of critically endangered animals, somatic cell cloning is considered the most appropriate method of ART. Somatic cell cloning can be beneficial for the reproduction of endangered species with limited female populations. However, gene and cell banks, and understanding of reproductive physiology and optimization of ART for wild animals are urgently required for further activation of artificial reproduction of endangered species, which enlarges its application and maintains biodiversity. Care should also be taken to consider ethical and legal issues associated with somatic cell cloning for conservation of endangered animals.

  • Pain, an adaptive but unpleasant sensation, is the most common symptom of numerous diseases in humans and animals. Although animal patients express this symptom frequently, a lack of communication abilities hinders its recognition by veterinary physicians, thereby leading to unsatisfactory management of the symptom. On the other hand, pain itself has its own neurological mechanisms, regardless of the disease that causes it. Thus, a physician may need to know the mechanisms underlying pain development in order to properly manage the symptom in a particular disease. In this review, we attempt to provide a brief introduction to the anatomical, physiological, and neurological basis of pain transmission and sensation. Although most knowledge about these mechanisms comes from studies in humans and laboratory animals, it is generally applicable to pet, farm, or zoo animals. In addition, we summarize pain behavior in several pet, farm, and laboratory animals for its proper identification. This information will help to identify and manage pain, and thus improve welfare, in animals.

  • Heat stroke can lead multi-organ damage with hemorrhage and necrosis in the lungs, heart, liver, kidneys, brain and Ut. Heat stroke occurs when the elevation of core body temperatures induce a failure of thermoregulatory mechanism. A four-year-old male African Lion(Panthera leo) showed clinical signs such as panting, tachycardia, hyperthermia, unconsciousness and mydriasis under He hish humidity and hot weather. Clinical treatment and pouring cool water was unsuccessful. Grossly, congestion of lungs and pleura was observed. Yellowish discoloration was observed in the renal cortex. Microscopically, the coagulative necrosis in kidney and congestion of lungs and spleen were observed. In our knowledge, this case was closely associated with acute heat stroke.

  • Aeromonas hydrophilia infection was diagnosed in captive Jackass penguins (Spheniscus demersus). Seven Jackass penguins showed clinical signs including depression and anorexia with greenish vomiting, but four penguins were died although extensive treatment was carried out. At necropsy, the penguins appeared to have hemorrhage and catarrhal inflammation of the small and large intestines and severe enlargement of the right hepatic lobe, elongation of the gall bladder and pyloric ulceration of the stomach. The ovaries observed atrophy and congestion. Microscopically, there were congestion, fat droplet within the cytoplasm of the hepatic cell, infiltration of lymphocytes in the stomach, vilous detachment and destroyed glandular epithelium in the small and large intestines. Aeromonas hydrophilia was isolated from the liver and small intestines. This case is the first report of an occurrence of Aeromonas hydrophilia infection at Jackass penguins in Korea.

  • Recently, the new genus Parkiana (Lecithoceridae) and its two new species, Parkiana matutinalis and Parkiana andasibensis, were described by the authors from Andasibe, Madagascar. Although the morphological descriptions and figures fully characterized the new genus with two new species in that paper, the journal issue in which the description appeared was published online-only, and the ZooBank LSID, required for validation of new names in electronic-only publications, was not included. Therefore, the present note serves to validate the names of the new genus and species, Parkiana, Parkiana matutinalis and Parkiana andasibensis, by fulfilling Code conditions for nomenclatural availability.

  • The animal in this case report was a 10-year-old male Taiwanese monkey (Macaca cyclopis) kept at a zoo of South Korea. Over the last three years, a cauliflower-shaped masses have been noted on the gingiva near the incisor and molar teeth on right maxilla. Consequently, this monkey have undergone surgical removal of the mass annually. Grossly masses showed pinkish color. Histopathological findings, typical spindle cell tumor composed of collagen fibers. Infiltration by plasma cells and lymphocytes is found unrelated to ulceration of the surface epithelium. This is the first report of peripheral odontogenic fibroma in a Formosan rock macaque.

  • The objective of this study is investigation of contamination levels and transfer rate of heavy metals and assessment of health risk effects in animal medicines. A total of sixteen items with 148 samples were obtained for this investigation from major herbal medicine producing areas and herbal markets from 2011 to 2012. Inductively coupled plasma mass spectrometer method was conducted for the quantitative analysis of Pb, Cd and As. In addition, the mercury analyzer system was conducted for that of Hg without sample digestion. The average contents of heavy metals in animal medicines were as follows : 1.55 mg/kg for Pb, 0.28 mg/kg for Cd, 0.70 mg/kg for As and 0.047 mg/kg for Hg respectively. The average contents of heavy metals in decoctions were as follows : 0.03 mg/kg for Pb, 0.01 mg/kg for Cd, 0.17 mg/kg for As and 0.003 mg/kg for Hg respectively. The average transfer rates of heavy metals from animal medicines to decoctions were 1.9% for Pb, 3.6% for Cd, 24.2% for As and 6.0% for Hg respectively. Cancer risks of animal medicines and decoctions through slope factor by ministry of environment republic korea and environmental protection agency was $1.36{\times}10^{-6}$ and $2.50{\times}10^{-8}$ for Pb and $7.46{\times}10^{-5}$ and $1.98{\times}10^{-5}$ for As (assuming that the total arsenic content was equal to the inorganic arsenic) respectively. The hazard index of heavy metals in animal medicines and decoctions was below recommended hazard index as 0.52 and 0.05 respectively. Taken together, cancer risks about Pb and hazard indexes of animal medicines and decoctions indicate that the majority of samples except for some samples with relative high contents of heavy metals were safe. But cancer risks about As of animal medicines indicate that the majority of samples were not relatively safe.

  • 창경원은 일제강점기 창경궁에 박물관과 동 식물원이 계획되면서 조성된 유원지다. 오락거리를 갖추고 즐거움을 주는 공간인 유원지는 현실에서 벗어난 낙원의 이미지를 재현해왔다. 본 연구는 창경원의 조성 과정과 공간 변화를 고찰하고, 그 결과 조성된 낙원으로서 유원지의 경관과 문화적 특성을 도출했다. 창경원의 조성 의도와 과정을 문헌으로 고찰한 결과, 창경원은 조선의 식민지화 과정에서 순종의 즐거움을 위한 '어원'이자, '대중을 위한 오락장'으로 조성되었으며, 개원과 동시에 일반인들에게 개방되면서 누구나 입장료만 지불하면 이용할 수 있는 공중을 위한 공간이 되었다. 창경원의 공간 구성은 근대 도면과 사진을 비교 분석해 파악했다. 창경원의 배치를 살펴보면, 중앙에는 박물관 영역, 북쪽에는 식물원 영역, 남쪽에는 동물원 영역으로 구성되었다. 식물원 지구에는 대온실을 중심으로 한 식물배양실 등 열대 식물의 전시 및 관리 기능이 집약되었으며, 동물원 영역의 연못은 수금방양소로 만들고, 이 주변으로 각종 동물사와 동물 온실을 신축했다. 박물관 시설은 본관 건물뿐만 아니라, 기존의 전각들을 전시 시설로 흡수했으며, 전각 사이에는 서양식 정원을 조성해 꽃을 계획적으로 재배하기도 했다. 1930년대에 이르면 아동운동장이나 말운동장과 같이 어린이들을 위한 놀이 공간이 만들어졌다. 다음으로 창경원의 낙원 이미지와 유원지 문화를 고찰했다. 그 결과, 첫째, 창경원은 동 식물원을 통해 희귀한 동물과 식물들을 대중적으로 접할 수 있는 낙원의 이미지를 가지게 되었다. 이는 꽃관상이나 동물 구경과 같은 새로운 대중오락을 만들어냈다. 둘째, 창경원은 도시의 일상에서 탈출할 수 있는 '도시 안에서 도시 밖 자연을 간직한 낙원'을 상징하며, 도시민의 여가 공간이 되었다. 셋째, 벚꽃의 개화기에 야간 개방이 시작되면서 창경원에서는 조명 효과를 중심으로 '환상적인 밤 경관'이 연출되었다. 이러한 밤벚꽃놀이는 각종 공연, 음주 등과 결합되면서 선정적으로 변해갔고, 그 결과 창경원은 일탈의 낙원이라는 이미지를 가지게 되었다. 창경원은 다양한 성격의 시설이 혼재되면서 유원지라는 새로운 유형의 공간을 만들어내는데 기여했으며, 사람들은 유원지에서의 경험을 통해 새로운 오락 문화를 수용했다.

  • A leiomyosarcoma that occurred in the right kidney with hepatic metastasis of a 15-year-old intact female Asian water buffalo (Bubalus arnee) in a zoo, Republic of Korea. The animal showed no clinical signs. Grossly, a firm and white mass (6.0 x- 5.0- x 4.0 cm) was observed in the renal capsule and multiple firm white nodules, measuring 1.0-2.5 cm, were present on the surface of the liver. Microscopically, tumor cells were spindle-shaped, the cell density was high, and complex fasciculated tumor cells showing longitudinal and transverse cross-sections were observed. Tumor cell nuclei was ordinarily cigar shaped and had rounded blunt ends. Immunohistochemically, tumor cells reacted intensely with anti-smooth muscle actin antibody. This is the first case report of a renal leiomyosarcoma with hepatic metastasis in a Asian water buffalo.

  • The hepatitis E virus (HEV) is a leading causative agent of acute hepatitis in humans. Zoonotic HEV strains have been isolated from several animal species, including pigs. New HEV variants have been recently isolated from camels in the Middle East. In the present study, fecal samples from fallow deer, formosan deer, alpaca, and guanaco were analyzed for the detection of HEV. One HEV strain was detected from guanaco, a species of camelids. The nucleotide sequence of guanaco HEV was identical to those of deer HEV-3 strains, which implied the cross-species transmission of HEV-3 from deer to guanaco.
