        The occurrence of allergic disease has increased harmfully in the last few decades. Atopic dermatitis (AD) is an allergic inflammation disorder characterized by itchy, red, swollen, cracked skin. Although the pathogenesis of AD is not fully understood, it is assumed that deregulation of T-helper 1 (Th1) and T-helper 2 (Th2) immune responses, a predominance of allergen-specific IgE, and interrupted epidermal barrier function are keys to the pathogenic mechanism. Activated T helper 2 (Th2) immune function is hallmark of various allergic diseases. Oxidative stress implicated in cutaneous damage in various inflammatory skin diseases. We investigated the effect of fermented soybean (SCGB1) on the improvement of AD. Soybean fermentation was carried out using B. amyloliquefaciense SCGB1 (KCCM11964P), which is known to produce of natural antibiotics. And then, we experiment of SCGB1 and soybean powder (NC) in DNCB-induced AD model. Mice were respectively oral administration of variety dose for 14 days. As a results, it was confirmed that serum Immunoglobulin E (IgE) expression was dose-dependently decreased in SCGB1 and NC compared to negative control, and it was reduced the skin pruritus inducing factor that Interleukin-31 (IL-31) mRNA level. In addition, the inflammatory cells were infiltration in skin for histological analysis. As a result, it reduced that epidermal hyperplasia, cancellation and aveolarization compared to negative control. These results suggest that SCGB1 may be effective for prevention and treatment of AD.

        Mycoplasma spp. are extracellular bacteria that colonize on the respiratory epithelium of humans and animals. It is a causative agent of pneumonia commonly complicated by opportunistic infectious bacteria. Mycoplasma spp. infection cause relatively mild disease in the absence of environmental stressors, but when complicated by secondary bacterial invaders the resultant disease can cause obvious clinical disease and severe production losses in intensively reared pigs Mycoplasma spp. are highly fastidious bacteria, difficult to culture and slow growing. Many species of Mycoplasma spp. are important pathogens causing respiratory infection in animals and known to induce huge economic losses. The aims of the present study were to develop a rapid isolation and culture method of wild type Mycoplasma spp. in pigs. We used Mycoplasma spp. genus specific direct PCR without DNA extraction procedure using PhireⓇ Animal Tissue Direct PCR Kit from the lung tissues with pneumonia lesions. Therefore, we could save the time for tissue processing and increase the accuracy of Mycoplasma spp. inclusion prediction in lung tissues. Thereafter, we used the optimized media to isolate and culture Mycoplasma spp. As the results, Mycoplasma spp. could be isolated and cultured quickly and efficiently. These results could provide an efficient strategy and method for the rapid and accurate isolation and culture of wild type Mycoplasma spp. in pigs.

        As the population ages, the number of households raising companion animals is increasing. Companion animal industry has recently been diversified through a combination of various industries such as beauty, rest, and insurance, and the share of this industry in the economy is gradually increasing. Dandruid keratoses, ticks, and various pathogenic bacteria are parasitized on the skin and hair of a dog to damage the hair and cause skin diseases. The purpose of this study was to investigate the effects of natural ingredients on the oil and moisture content of dog skin when using natural shampoos and using these shampoos. In this study, we measured the water content of four poodles of 1 year and 4 years old. The natural shampoo used in 4 rats was prepared and used directly. The results of this study showed that the water content in the forelimb of the experimental dog was almost unchanged when using the ordinary shampoo, but it increased with the use of the natural shampoo. Especially, when using natural shampoo for 3 weeks, it was confirmed that the water content of ordinary shampoo increased about 55.71% over 3 weeks. On the other hand, when using a general shampoo, the water content of the neck of the experimental dog was almost unchanged, and even when using the natural shampoo, the moisture content was almost unchanged. These results suggest that natural shampoos will have a better effect on maintaining the moisture content of companion animals compared to ordinary shampoos.

        Acorus gramineus is a herb used frequently in oriental medicine. Clinically, the effects of Acorus gramineus are known as awakening of one’s consciousness, removal of sputum, and relief of autism. Experimentally, Acorus gramineus root(AGR)-induced cerebral blood flow increase depending on the concentration causes diverse responses of blood pressure and regional cerebral blood flow and possesses strong inhibitory effects of apoptosis in the nervous system. We investigated the effects of AGR water extract on the adipose tissue status. Male C57BL/6 mice were fed high fat diet and a total of 35 mice were divided into 5 groups: normal group, control group, and groups treated with AGR water extract at concentrations of 20, 100, and 500 mg/kg. The mice were treated by oral administration once a day for consecutive 6 weeks, and their weight changes were monitored. As the results, the groups treated with AGR water extract showed weight loss. Also, the weights of liver, epididymal fat, retroperitoneal fat and peri-renal fat were decreased in the groups treated with AGR water extract. In histopathological examination, the sizes of adipose tissues decreased in liver, epididymal fat, retroperitoneal fat, and peri-renal fat. These results indicate that AGR water extract have an anti-obesity activity, which could be used as an useful material to decrease body adipose tissues.

        Hyperlipidemia has been ranked as one of the greatest risk factors contributing to the prevalence and severity of coronary heart diseases. The pharmacological actions of tangerine (Citrus unshiu) peel include the facilitation of fat digestive enzymes. Also, guarana (Paullinia cupana) has been used for stimulants and tonics over a long period. In this study, we aimed to optimize the mixed ratio of organic tangerine peel and guarana extracts to suppress fat accumulation. To determine the optimized the mixed ratio of tangerine (Citrus unshiu) peel extract (C) and guarana (Paullinia cupana) extract (P) on adipogenesis, maturing preadipocytes were incubated during the 8-day induction period with various ratio of the mixed extracts groups like as Vehicle (DMEM 200 μl/ml), Con (MDI DMEM 200 μl/ml), C10 (MDI DMEM 180μl/ml+C 20 μl/ml), C9:P1 (MDI DMEM 180 μl/ml+C 18 μl/ml+P 2 μl/ml), C5:P5 (MDI DMEM 180 μl/ml+C 10 μl/ml+P 10 μl/ ml), P10 (MDI DMEM 180 μl/ml+P 20 μl/ml). Thereafter, the adipocytes were stained with Oil-Red-O and analyzed for lipid contents. As the results, organic tangerine peel and guarana extracts were revealed to reduce fat accumulation in 3T3-L1 cells. The fat accumulation significantly decreased in C5:P5 group, which is equally mixed with organic tangerine peel and guarana extracts, as compared to other groups. Based on these results, we found the optimized ratio with organic tangerine peel and guarana extracts to suppress fat accumulation. We suggest that this optimized organic tangerine peel and guarana complex might reduce effectively the serum lipid components and improve the lipid metabolism in hyperlipidemic patient.

        Recently, several companies have released H. pylori stool antigen (HpSA) test kits. However, there is little information about the usefulness of HpSA testing for Helicobacter felis, which is the major Helicobacter species in cats. The aim of the present study was to compare diagnostic methods for diagnosis of H. felis with HpSA tests and PCR assay using cat stools or gastric mucosa. Male cats (n=6) were infected with H. felis ATCC 49179 (1.0 × 109 CFU /cat) by intragastric inoculation two times at 3-day intervals, and stool specimens of cats were collected 1, 3, 5, 7, 14, and 21 days after infection for HpSA testing and H. felis-specific PCR. For the results, sensitivities of the HpSA test and PCR analysis were 50.0% and 83.3% respectively. Cats were sacrificed 21 days after H. felis inoculation, and gastric tissues were homogenized. All gastric biopsy specimens were positive based on a rapid urease test (RUT) (6/6, 100%) and PCR (6/6, 100%). Based on these results, the HpSA kit is useful and effective for monitoring H. felis infection using stool specimens. If an HpSA test could be made with H. felis antibodies in the future, its sensitivity could be increased further. Further, PCR assay could be successfully used to detect H. felis in stools. Application of this HpSA kit and PCR assay can be utilized as a non-invasive strategy to identify H. felis in cats.

        In this article, we reviewed how the therapy animals for animal assisted intervention (AAI) could be treated ethically in the aspects of animal welfare. Our goal is to reexamine the animal-human partnership from the animal's viewpoint to see what the benefits might be for the animal, or to see if the raising, training, and deployment of assistance and therapy animals is causing significant degradation in animal welfare. Also, we want to make an impression for AAI therapists to examine their ethical responsibility for the welfare of their therapeutic assisting animals. Animal assisted psychotherapist must respect the integrity of the animals and recognize that their rights and safety are safeguarded. In this article, we intend to provide recent advanced knowledge on the animal welfare and ethical reference in the filed of animal-assisted intervention.

        Mycoplasma hyorhinis (M. hyorhinis) is considered an etiological agent of arthritis in suckling pigs. Recently, some M. hyorhinis strains were shown to produce pneumonia that is indistinguishable from the mycoplasmosis caused by M. hyopneumoniae. In this study, we developed a sensitive and specific PCR assay to detect M. hyorhinis and applied the developed PCR assay for detection of Mycoplasma infection in clinical piglets infected with M. hyorhinis. We developed a new PCR assay using a M. hyorhinis-specific primer pair, Mrhin-F and Mrhin-R, designed from the Mycoplasma 16S-23S rRNA internal transcribed spacer (ITS) region. The primers and probe for the assay were designed from regions in the Mycoplasma 16S-23S rRNA ITS unique to M. hyorhinis. The developed PCR assay was very specific and sensitive for the detection of M. hyorhinis. The assay could detect the equivalent of 1 pg of target template DNA, which indicates that the assay was very sensitive. In addition, M. hyorhinis PCR assay detected only M. hyorhinis and not any other Mycoplasma or bacterial spp. of other genera. The new developed PCR assay effectively detected M. hyorhinis infection in pigs. We suggest that this PCR assay using a M. hyorhinis-specific primer pair, Mrhin-F and Mrhin-R, could be useful and effective for monitoring M. hyorhinis infection in pigs.

        Environmental enrichment is the process of providing stimulating environments for zoo animals in order for them to demonstrate their species-typical behavior, to allow them exercise control or choice over their environment, and to enhance their well-being. We are aimed to provide the available knowledges about the animal enrichment programs for zoo animals through literature review. As the results, we reviewed the design of stimulating and naturalistic enclosures, the housing etc. Enrichment includes the design of stimulating and naturalistic enclosures, the housing of appropriate social groups in zoo, and the introduction of objects, sounds, smells or other stimuli in the animal’s environment. Conclusionally, environmental enrichment is just as critical to Zoo animal welfare as nutrition and veterinary medicine. At the zoos, enrichment will be an integral part of the daily care of the species in the collection.

        There are so many animals, mostly dogs, that have been abandoned by their families to roam around the streets of Korean cities and towns. These animals often die in a miserable way such as being run over or being killed and eaten. It is a terrible site to see these dogs, lost and confused in a world without kindness. One solution to the problem is adoption, as it can save life and by example become a driving force to fundamental change in the thinking of other and in society. We are aimed to conduct the survey research to evaluate the university students's awareness of the adoption of the abandoned animals. We deals with the findings obtained from extensive interviews with a representative samples. The objectives of interviews included 789 students in Wonkwang, Keimyung and Chosun University.

        Animal Assisted Intervention (AAI) is a goal oriented intervention that intentionally includes or incorporates animals in health, education and human service for the purpose of therapeutic gains in humans. Animal assisted interventions incorporate human-animal teams in formal human service such as Animal Assisted Therapy (AAT) or Animal Assisted Education (AAE). Animal Assisted Activity (AAA) is the informal AAI often conducted on a volunteer basis by the human-animal team for motivational, educational and recreational purposes. AAI could be used for rehabilitation therapy and psychotherapy for patients with various symptoms. AAI uses animals, mostly dogs, to aid in healing patients holistically. Dogs have an overwhelming gratitude and exuberance for life and this effect on people is astounding. Furthermore, AAI has been researched and its effectiveness on patients' outcomes and healing is documented. With a soaring trend of the incorporation of complementary therapies into the mainstream of therapy and health care, animal-facilitated therapy has become a popular interest for the therapy team to integrate into a patient's plan of therapy. The purpose of this manuscript is to raise awareness about AAI and to familiarize readers with the concepts surrounding AAI so that they can be informed aids to clients who might benefit from the technique.

        Canine respiratory coronavirus (CRCoV) is commonly associated with canine kennel cough worldwide. Clinically infected dogs present coughing, sneezing, and nasal discharge. Severe infections may progress to pneumonia. Through serological surveys, CRCoV has been identified as a worldwide pathogen found in the respiratory tracts of dogs suffering from mild or severe respiratory disease. In this study, three dogs were obtained from a dog kennel. Over the previous 5 days, the dogs showed coughing, sneezing, and nasal discharge. To detect the etiologic pathogen, we performed multiplex RT-PCR (mRT-PCR) to amplify the genes encoding canine influenza virus matrix protein, canine distemper virus nucleocapsid protein, and CRCoV spike protein. Dot blotting was achieved with a CRCoV-specific probe. Nasal-secreting CRCoV was detected by the 442 bp CRCoV-positive PCR reaction in the nasal swabbing samples from dogs. Further, CRCoV-positive reactions by dot blot hybridization were detected in the nasal swabbing samples from dogs. In conclusion, we detected CRCoV in kenneled dogs with respiratory disease in Korea. Multiplex RT-PCR was able to detect successfully CRCoV infection in dogs. We suggest that mRT-PCR would be useful and effective for monitoring CRCoV infection in various kinds of dogs.

        Salsola komarovi Iljin is a halophyte and herbaceous annual native to the sand dunes and beaches of Japan, northern China, Sakhalin, and Korea. The plants have been known as an ecologically important species for enhancing formation of sand dunes in Korea. The purpose of this study was to examine the anti-gastric ulcer effect of Salsola komarovi Iljin halophyte in an HCl-ethanol-induced gastritis model. SD rats (7-weeks-old) were divided into normal (I, n=10), control (II, 60% HCl-ethanol + water, n=10), 60% HCl-ethanol + Ranitidine 300 mg/kg (III, n=10), 60% HCl-ethanol + Salicornia herbacea L. 500 mg/kg (IV, n=10), 60% HCl-ethanol + 50% alcohol extract of Salsola komarovi Iljin 500 mg/kg (V, n=10), and 60% HCl-ethanol + water extract of Salsola komarovi Iljin 500 mg/kg (VI, n=10) groups. Salsola komarovi Iljin significantly suppressed gastric lesions and ulcers in the 60% HCl-ethanol-induced gastric model. Especially, 500 mg/kg of 50% alcohol extract of Salsola komarovi Iljin showed significant inhibitory effects against gastritis. Especially, 50% alcohol extract of Salsola komarovi Iljin 500 mg/kg showed a significantly inhibitory effect, which was more potent than that of 300 mg/kg of Ranitidine. In histopathological analysis of the animal model, Salsola komarovi Iljin attenuated gastric ulcer formation. Our results suggest that Salsola komarovi Iljin has inhibitory effects against gastritis and gastric ulcers and could be developed as a new anti-gastric ulcer agent.
