Recently, there has been a marked increase in the use of bioactive products resulting from the fermentation of natural substances by microorganisms. In this study, Opuntia humifusa (OH) was fermented using Lactobacillus plantarum (fermented Opuntia humifusa; fOH). We then examined the anti-obesity effect of fOH in mice fed a 45% Kcal high fat diet (HFD). In this study, mice were treated with fOH concentrations of 100, 200, and 400 mg/kg. The mice in the control group were treated with OH at a concentration of 400 mg/kg based on previous animal experiments. All of the mice given a continuous HFD showed an increase in their weight, the density of abdominal fat, and the accumulated periovaric and abdominal fat. All of these obesity-linked factors, however, were significantly decreased in the groups treated with fOH at concentrations of 200 and 400 mg/kg. Mice treated with fOH at 100 mg/kg did not show a significant decrease in these obesity-linked factors compared to the control group. It appears that fOH fermented by L. plantarum has a greater anti-obesity effect in HFD-supplied mice compared to unfermented OH. While further studies of fOH are needed to examine its effect on obesity, hyperlipidemia, hepatic steatosis, renal function, and type II diabetes with its relevant complications, fOH may have significant therapeutic potential in the treatment of metabolic syndrome.
The movie WALL-E shows the Earth which has been overrun with garbage and devoid of plant and animal life, and humans who try to restore the ecosystem. The aim of this study is to find the implications of children's education with a detailed analysis of the movie's theme. The analysis method is the interpretive analysis model that is one of the qualitative methods of data analysis based on the concept of Wolcott. First, the Earth is an abandoned planet covered in trash: the Axiom is a haven for morbidly obese and indolent people. The main area of the earth's destruction, and the captain's cabin is the place to find a clue to awakening and change. Second, with the lapse of time, the Axiom becomes a ship allowing their return to earth. The Earth, recognized as their homeland, turns in to the land of hope when people return. Third, the cleaning robot Wall-E, as a main agent of change, has changed humans as well as itself. The results showed that we found nature-friendly development, destruction of nature, the criticism of modern civilization, the sanctity of life, ecological consciousness, coexistence, symbiosis and a win-win principle in our research.

In order to evaluate the anti-oxidative capabilities of Angelica dahurica Radix ethanol extract (ADEE), we analyzed the contents of polyphenol and flavonoid compounds and the electron donating ability from ADEE. For animal experimentation, the test agent was topically applied to the artificial tanning spots which were induced by 1,500 mJ/$cm^2$ of ultraviolet B radiation on the backs of brown guinea pigs weighing approximately 450~500g. The test agent of $30{\mu}{\ell}$ was applied (6areas per group) twice a day, five days a week, for five weeks. On completion of the experiment, the animals were sacrificed under anesthetization, and the artificial tanning spots were obtained by biopsy punch and stained with H&E to observe the histological change in the epidermis and dermis. As a result, the contents of polyphenol and flavonoid compounds in ADEE were 20.7mg/g and 19.5mg/g respectively. As the for electron-donating capability of ADEE, it was observed that ADEE displays a dose-dependent antioxidative capacity of 14.8% and 19.8% at the concentration of 500 and 1000 ${\mu}g/m{\ell}$ respectively. Tissue staining with H&E revealed that the epidermis of the control group was slightly thicker than that of the other groups. However no inflammation or any other undesirable effect on the skin tissue due to ADEE was observed. These results indicate that ADEE is of value as a natural antioxidant.
In Charlotte's Web, each character motivates the other and strives for the new generation based upon motherhood. The intersection between life and death is directly and symbolically addressed as a component of the natural life cycle. Borrowing Kristeva's theory of the semiotic, the symbolic and the chora, this study investigates the dialectical oscillation between the semiotic and the symbolic and the social circumstances of subjects in signification as well as highlights the features of character growth. From a feminist perspective, herein, motherhood is translated not only as a robust foundation for relations among characters but also as an impetus for developing into a good and influential individual who embraces all organisms with care and consideration. Charlotte's Web clearly shows how the semiotic and symbolic elements of each being, united by motherhood, interact and lead to positive change. Though the world appears to consist of incompatible ingredients, they are combined. Charlotte's Web awakens the fact that their harmony makes a commitment to building a more wonderful place. It can be suggested that Charlotte's Web, where animal characters contain two tendencies of the human mind, exhibits human development proceedings.

Soft tunic syndrome (STS) is a protozoal disease caused by Azumiobodo hoyamushi in the edible ascidian Halocynthia roretzi. Previous studies have proven that combined formalin-hydrogen peroxide ($H_2O_2$) bath is effective in reducing STS progress and mortality. To secure target animal safety for field applications, toxicity of the treatment needs to be evaluated. Healthy ascidians were bathed for 1 week, 1 h a day at various bathing concentrations. Bathing with 5- and 10-fold optimum concentration caused 100% mortality of ascidians, whereas mortality by 0.5- to 2.0-fold solutions was not different from that of control. Of the oxidative damage parameters, MDA levels did not change after 0.5- and 1.0-fold bathing. However, free radical scavenging ability and reducing power were significantly decreased even with the lower-than-optimal 0.5-fold concentration. Glycogen content tended to increase with 1-fold bathing without statistical significance. All changes induced by the 2-fold bathing were completely or partially restored to control levels 48 h post-bathing. Free amino acid analysis revealed a concentration-dependent decline in aspartic acid and cysteine levels. In contrast, alanine and valine levels increased after the 2-fold bath treatment. These data indicate that the currently established effective disinfectant regimen against the parasitic pathogen is generally safe, and the biochemical changes observed are transient, lasting approximately 48 h at most. Low levels of formalin and $H_2O_2$ were detectable 1 h post-bathing; however, the compounds were completely undetectable after 48 h of bathing. Formalin-$H_2O_2$ bathing is effective against STS; however, reasonable care is required in the treatment to avoid unwanted toxicity. Drug residues do not present a concern for consumer safety.
About 2-year old northern goshawk (Accipiter gentilis) which is designated as natural monument (#323-1) in Republic of Korea was rescued by a local farmer and presented with a 2-weeks history of pain, swelling, stiffness and limping. On physical examination, plantar pododermatitis and digit IV weakness were observed. Radiographic findings also showed bone lyses with soft tissue swelling in the foot. A definite diagnosis was made as stage III bumble foot after multidisciplinary approach of the patient. Bacterial culture was performed, and concurrently antibiotic susceptibility testing is determined using wound site exudates specimen. Bacterial isolates were identified as Staphylococcus aureus, known normal skin flora. Treatment was initiated with surgical incision and necrotized tissues removal. Lavage-drainage and ball bandage were applied with topical mupirocin ointment application. Doughnut shaped pad was attached on bottom of the ball bandage to reduce weight bearing. After three weeks of intensive care, the wound site completely healed but digit IV weakness remained permanently. The goshawk returned to nature after eight weeks after treatment.
High levels of inflammatory cytokines were proposed contributors to the pathogenesis of a various inflammatory skin disorders. Therefore, investigating the immune response of the inflammatory skin disorder allows a better understanding of pathogenesis of a various inflammatory skin disorders and therapeutic approaches. The aim of this study was to analyze of the immune response in dogs with chronic inflammatory skin disease. To this aim, the present study evaluated relative mRNA expression of canine $IFN-{\gamma}$, IL-4, $TGF-{\beta}$ and IL-10 using TaqMan realtime PCR assays and semi-quantitative RT-PCR in freshly isolated peripheral blood mononuclear cells from twenty dogs with chronic inflammatory skin disease and ten normal dogs. The relative mRNA expression levels of IL-4 mRNA were significantly higher in dogs with chronic inflammatory skin disease than those in normal dogs (P < 0.01). The results of present study also showed a tendency towards increased expression of IL-10 transcripts in dogs with chronic inflammatory skin disease. However, there were no significant differences in the levels $IFN-{\gamma},\;TGF-{\beta}$ between normal and chronically inflammed dogs. In addition, the concentration of serum IgE was significantly increased in dogs with chronic inflammatory skin disease compared with those in normal dogs (P < 0.01). In histopathological examination, we found that there were markedly increased mast cell counts in chronically inflammed dogs (P < 0.05). These results suggest that the pathogenesis of chronic inflammatory skin disease might be associated with a T-cell mediated inflammatory responses characterized by a Th2-skewed immune response. Based on these results, the modulation of Th1/Th2 balance may be an effective therapeutic strategy for the treatment of chronic inflammatory skin disease.

Antimicrobial resistance has been a well-recognized problem ever since the introduction of penicillin into clinical use. History of antimicrobial development can be categorized based on the major antibiotics that had been developed against emerging resistant $pathogens^1$. In the first period from 1940 to 1960, penicillin was a dominating antibiotic called as a "magic bullet", although S.aureus armed with penicillinase led antimicrobial era to the second period in 1960s and 1970s. The second stage was characterized by broad-spectrum penicillins and early generation cephalosporins. During this period, nosocomial infections due to gram-negative bacilli became more prevalent, while those caused by S.aureus declined. A variety of new antimicrobial agents with distinct mechanism of action including new generation cephalosporins, monobactams, carbapenems, ${\beta}$-lactamase inhibitors, and quinolones characterized the third period from 1980s to 1990s. However, extensive use of wide variety of antibiotics in the community and hospitals has fueled the crisis in emerging antimicrobial resistance. Newly appeared drug-resistant Streptococcus pneumoniae (DRSP), vancomycin-resistant enterococci (VRE), extended-spectrum ${\beta}$-lactamase-producing Klebsiella, and VRSA have posed a serious threat in many parts of the world. Given the recent epidemiology of antimicrobial resistance and its clinical impact, there is no greater challenge related to emerging infections than the emergence of antibiotic resistance. Problems of antimicrobial resistance can be amplified by the fact that resistant clones or genes can spread within or between the species as well as to geographically distant areas which leads to a global concern$^2$. Antimicrobial resistance is primarily generated and promoted by increased use of antimicrobial agents. Unfortunately, as many as 50 % of prescriptions for antibiotics are reported to be inappropriate$^3$. Injudicious use of antibiotics even for viral upper respiratory infections is a universal phenomenon in every part of the world. The use of large quantities of antibiotics in the animal health industry and farming is another major factor contributing to selection of antibiotic resistance. In addition to these background factors, the tremendous increase in the immunocompromised hosts, popular use of invasive medical interventions, and increase in travel and mixing of human populations are contributing to the resurgence and spread of antimicrobial resistance$^4$. Antimicrobial resistance has critical impact on modem medicine both in clinical and economic aspect. Patients with previously treatable infections may have fatal outcome due to therapeutic failure that is unusual event no more. The potential economic impact of antimicrobial resistance is actually uncountable. With the increase in the problems of resistant organisms in the 21st century, however, additional health care costs for this problem must be enormously increasing.
Five dogs diagnosed as apocrine gland adenocarcinoma (AGAC) of the anal sac based on cytology and/or histology. Mean age of these dogs was 11 years old. One dog treated with supportive care without other medical interventions for hypercalcemia was died one month after diagnosis. Other four dogs were treated with chemotherapy and one of these dogs was intervened with complete surgical resection. Two months after the diagnosis, one of the dogs treated with chemotherapy died. The survival time of other survived three dogs from the time of diagnosis was 19, 9, and 13 months respectively and they are still alive at this time. After chemotherapy, three dogs were managed generally in good body condition and maintained as similar in size as time of diagnosis. The results are suggested that it is worthwhile to try chemotherapy for managing AGAC in dogs especially complicated or metastasized to regional lymph nodes.

Vertigo is one of the subjective symptoms which appears commonly in so many diseases that it is often neglected. But it needs active medical care because it can be a forewarning of serious illness like cerebral apoplexy. This thesis makes a study of vertigo in view of Hyungsang medicine. The followings are the conclusion drawn in diagnosis and treatment of Vertigo: Excess in the upper and deficiency in the lower part(上實下虛) is a main cause of male vertigo. Deficiency in the upper and excess in the lower part(下虛上實) is a general cause of female vertigo. Vertigo is also caused by the insufficiency of the kidney water(腎水) or reservoir of marrow(髓海). persons of Jung pe(精科) with large check bones , those of Fish type(魚類) with Dig mouth and thick lips ; and those with large heads are mainly attacked by this cause. A fleshy person's vertigo comes from the deficiency of Ki and damp phlegm(氣虛濕症) so it is cured by reinforcing Ki, removing dampness and dispelling phlegm. A slim person's vertigo comes from the deficiency of blood and dryness heat(血虛有火) so it is treated by tonifying the blood, cleaning heat away the heat. In case of womanly shaped male and manly shaped female, the vertigo is due to the phlegm fire. Wind-heat(風熱) can cause vertigo generally 施 the persons of following types : wind type(風人), running animal type(走類),bird type(烏類), and Yangmyung meridian type (陽明形). Vertigo also comes from consumption. The deficiency of Ki can be a cause of vertigo in case of male; persons with pale complexion; and those with pronounced noses. The deficiency of blood can be a reason of vertigo in the persons of Hyul type(血科) and those with pale eyelids and lips. The hypofunction of the splean and stomach brings on the deficiency of Ki and blood, which can give rise to the vertigo for those with large nose and mouth. The old people's vertigo comes from the hypofunction of Ki, blood, Yin and Yang.
