Toxocariasis is a worldwide zoonosis caused by larvae of ascarid nematodes of dogs or cats, Toxocara canis or T. cati. Diagnosis of human toxocariasis currently relies on serology that uses T. canis excretory-secretory antigen to detect specific IgG antibodies by ELISA. We investigated the serodiagnostic efficacy of ELISA using crude antigen of T. canis larvae (TCLA). Serum specimens of 64 clinically confirmed toxocariasis, 115 healthy controls, and 119 other tissue-invading helminthiases were screened by ELISA using TCLA. The ELISA using TCLA showed 92.2% (59/64 patient samples) sensitivity and 86.6% (103/119) specificity. Its positive diagnostic predictivity was 78.7% and negative predictivity was 97.8%. No serum of healthy controls reacted but that of anisakiasis (45.5%), gnathostomiasis (19.2%), clonorchiasis (15.8%), sparganosis (11.1%), and cysticercosis (6.3%) cross-reacted. Immunoblot analysis on TCLA recognized antigenic proteins of 28- and 30-kDa bands in their dominant protein quantity and strong blotting reactivity. The present results indicate that the ELISA using our TCLA antigen is acceptable by the sensitivity and specificity for serodiagnosis of human toxocariasis. ELISA with TCLA is recommended to make differential diagnosis for patients with any sign of organ infiltration and eosinophilia.

The population of domestic companion animals is estimated to be about 10 million now. In recent years, the domestic pet market has been launching a wide range of products and services for high quality, smart and well-being. As a result, the market size will increase from 900 billion won in 2012 to 2.3 trillion won in 2016, which has more than doubled in five years. The industry expects to reach 6 trillion won by 2020, expecting 3 trillion won this year. In particular, domestic dogs and cats market is estimated at 275.5 billion won, accounting for 19% of the domestic animal market and 1.425 billion won for the world market. However, despite the growing market for companion animals products, unfortunately the import dependence on related industrial goods is still high and the quality of service is very low. Unlike Europe and the United States, 90% of companion animals are housed in apartments, often causing problems in the health and safety of companions and companions. The purpose of this study is to develop a smart house for companion animals with environmental friendliness and AI function that can be won in competition with products of developed countries. The results of this study are expected to contribute to the creation of a new value - added base for the related industries through the strengthening of the competitiveness of the related SMEs and further the effect of employment increase and import substitution.

Various trials have been conducted to develop therapies for serious untreatable diseases. Among these, those using stem cells have shown great promise, and adipose-derived mesenchymal stem cells (ADMSCs) are easier to obtain than other types of stem cells. Prior to clinical trials, characterization of ADMSCs with monoclonal antibodies should be performed. However, it is difficult to use species-specific antibodies for veterinarians. This study was conducted to confirm the panel of human antibodies applicable for use in immunophenotypic characterization of canine adipose-derived stem cells and feline ADMSCs extracted from subcutaneous adipose tissue collected during ovariohysterectomy. For flow cytometric immunophenotyping, the third passages of canine ADMSC and feline ADMSC and human CD31, CD34, CD42, CD44, CD62 and CD133 antibodies were used. Of these, CD133 reacted with canine cells (3.74%) and feline cells (1.34%). CD133 is known as a marker related with more primitive stem cell phenotype than other CD series. Because this human CD133 was not a species-specific antibody, accurate percentages of immunoreactivity were not confirmed. Nevertheless, the results of this study confirmed human CD133 as a meaningful marker in canine and feline ADMSCs.

The Shihwa wetland, a newly developed constructed wetland prototype in Korea with an area of approximately 104 ha, was established to improve the water quality severely polluted inflow streams into Lake Shihwa. Because this wetland could play a role as an ecological park in addition to improving the water quality, an ecological impact of the Shihwa constructed wetland has been a national concern. This paper focused on reporting the survey results for fauna among the entire investigation results for 3 years. A total of 129 terrestrial insect species have been observed from August 2001 to June 2002. Among them, Ischnura asiatica (Brauer) (order Odonata), Scymnus species (order Coleoptera) and Orthopteran species were frequently found in the reed bushes. A total of 77 bird species were recorded in a seasonal count, the maximum number of species was 34 in winter and the maximum number of individuals was 4,599 in summer. For the freshwater fish, only 4 species were found in 2000, however in 2001 and 2002, 12 species and 459 individuals were collected at four survey points. Among these 12 species, the dominant species were Mugil cephalus(36%), followed by Carassius auratus (25%) and Rhinogobius brunneus (22%). Meanwhile,12 individuals of Oryzias latipes were observed nearby, mostly downstream of the wetland. For the Herpetofauna at four survey areas, 3 species of amphibians and 3 species of reptiles were recorded. Because of remaining salinity in the soil of the Shiwha constructed wetland, Herpetofauna inflow to the wetland was scanty and mainly inhabited the upstream area. A total of 8 mammal species were recorded. Small-sized species were the striped field mouse, the Ussurian harvest-mouse, the Manchurian reed vole and the brown rat. Middle- and large-sized species were Korean water-deer, Korean raccoon dogs, Korean yellow weasels and feral cats.

Nowadays, the family system has changed from a large extended family group to a more nuclear family and the number of people who live by themselves has been increasing. Moreover, Korea is becoming an aged society, and pets are becoming more important as leave the family home. So a lot of people in Korea now consider pets as their family members due largely to the drastic change of their life style. Therefore, the rate of importing commodities for pets like cats and dogs has been increasing dramatically. In this study, in response to the growing interest in the pet industry, I have studied recent trends and types in the pets wear markets which are still in the first stage of development in Korea. In order to enhance the possibility of mass producing pets ready-made clothes for making the unit cost lower, firstly, I presented a new basic design and pattern of pets wear made up of general textile. After that, following basic purpose of pet wear, I classified decorative clothes into party wear, everyday wear and street wear and then I developed the pattern and made a pair of works for each item totaling 6 in all. I hope that the number of Korean companies which can enhance their reputation through by marketing these products in Korean as well as all around the world will increase. I believe this will be possible because by taking advantage of the easy pattern developed in this thesis. They will be able to mass produce their own high quality pets wear brand.
