  • A 12-year-old neutered male Maltese was brought to our hospital with loss of appetite, generalized alopecia, anemia, and a palpable abdominal mass. Ultrasonography revealed multiple abdominal masses in the liver and spleen. Subsequently, splenectomy and liver biopsy were performed, and the masses were histologically diagnosed as metastatic fibrosarcomas of unknown primary origin. The owner refused further investigations such as computed tomography and hepatectomy, therefore, we decided to initiate chemotherapy in the form of metronomic therapy with toceranib phosphate, which has several advantages, such as better tolerability, low cost, and convenience. The size and number of hepatic fibrosarcomas continued to increase despite continued administration of toceranib (10 mg/dog, PO, q48h). The dog died approximately 43 days after initiation of the toceranib treatment. To the best of our knowledge, this is the first report on toceranib therapy for metastatic hepatic fibrosarcoma in a dog.

  • An eight-year-old, 28-kg male bull terrier who showed signs of lethargy and cough was referred for further evaluation of congestive heart failure. On presentation, physical examination revealed a systolic murmur at the left apex of the heart. Moreover, chest radiograph evaluation confirmed the mild alveolar and interstitial patterns in the caudal lung lobes and a grossly enlarged left atrium and left ventricle. Electrocardiography showed atrial fibrillation with a wide QRS complex, and transthoracic echocardiography revealed marked enlargement of the left atrium with abnormal morphology of the mitral valve. The thickened, hammer-like appearance and abnormal diastolic motion of the mitral valve leaflets were characterized by decreased leaflet separation and doming of the valve. The diagnosis was mitral stenosis with congestive heart failure and atrial fibrillation. The owner declined interventional valvuloplasty. Medical treatment included furosemide, pimobendan and diltiazem. Regular health check-ups have shown that vitality and clinical signs have improved considerably, and the dog have remained stable for 6 months after the presentation.

  • Endometrial tissue is a known source of mesenchymal stem cells (MSCs). We isolated canine endometrial stem cells from canine endometrial tissues using an enzymatic method and confirmed the immunophenotype of mesenchymal stem cells and multilineage differentiation. Canine endometrial tissues were obtained from canine ovariohysterectomy surgery and isolated using 0.2% collagenase type I. We measured the immunophenotype of stem cells using flow cytometry. To confirm the differentiation ability, a trilineage differentiation assay was conducted. In this study, canine endometrialderived MSCs (cEM-MSCs) were isolated by enzyme treatment and showed a spindle-shaped morphology under a microscope. Moreover, cEM-MSCs showed a trilineage differentiation ability. In this study, the canine endometrium was a good source of MSCs.

  • A commercial chromogenic agar medium (DFI) was supplemented with glucose (mDFI) to enhance the specificity of Enterobacter sakazakii (E. sakazakit) detection. Escherichia vulneris (E. vulneris), a putative false-positive strain on the DFI medium, produces ${\alpha}$-glucosidase. The enzyme ${\alpha}$-glucosidase hydrolyzes a substrate, 5-bromo-4-chloro-3-indolyl-${\alpha}$, D-glucopyranoside $(X{\alpha}Glc)$, producing green colonies. E. sakazakii strains produced green colonies on both DFI and mDFI agar, whereas E. vulneris produced green colonies on DFI agar but small white colonies on mDFI agar. E. sakazakii and E. vulneris were also readily differentiated by colony color when the mixed culture of the two strains was plated on mDFI agar and incubated for 24 h at $37^{\circ}C$. The results indicate that the selectivity of the commercial chromogenic agar medium could be improved by a simple supplementation with glucose.

  • Tone mapping for High Dynamic Range(HDR) image provides matching human visual perception between real world scene and displayable devices. Recently, a tone mapping algorithm based on localized gamma correction is proposed. This algorithm is using human visual properties of contrast and colorfulness with background intensity, generating a weight map for gamma correction. However, this method have limitations of controlling enhancement region as well as generating halo artifacts caused by the weight map construction. To overcome aforementioned limitations, proposed algorithm in this paper modifies previous weight map, considering base layer intensity of input luminance channel. By determining enhancement region locally and globally based on base layer intensity, gamma values are corrected accordingly. Therefore, proposed algorithm selectively enhances local brightness and controls strength of edges. Subjective evaluation using z-score shows that our proposed algorithm outperforms the conventional methods.

  • Broussonetia papyrifera and Lonicera japonica have long been used in the treatment of inflammatory disorders, especially respiratory inflammation, in Chinese medicine. Previously, phytoformula (BL) containing B. papyrifera and L. japonica was found to exert strong anti-inflammatory activity in vitro and in vivo. In this study, the effects of BL on lung inflammation including bronchitis were examined in vitro and in vivo. BL (10-100 ${\mu}g$/ml) inhibited nitric oxide (NO) production of lipopolysaccharide (LPS)-treated alveolar macrophages, MH-S cells, primarily by down-regulating inducible NO synthase. BL also inhibited production of the proinflammatory cytokines, TNF-${\alpha}$ and IL-6. Against an animal model of pleural cavity inflammation, BL (200-400 mg/kg) significantly inhibited 5 h and 24 h carrageenan-induced pleurisy in rats when administered orally. Additionally, BL inhibited experimental bronchitis induced by intratracheal instillation of LPS to rats. Taken together, these results indicate that BL may be effective for the treatment of human lung inflammation as well as bronchitis.

  • A 8-year-old intact female Siamese cat with chronic vomiting was referred to the Veterinary Teaching Hospital of Chungnam National University. The cat was diagnosed as lymphocytic-plasmacytic enteritis by complete blood count, blood chemistry, radiography, ultrasonography and histopathologic examination following small intestine biopsy. The cat show good prognosis to date after continuous hypoallergenic diet providing and low-dose prednisolone therapy.

  • An 8-year old female Korean Short Hair cat with a history of paralysis of both hind limbs less than 1 hour before admission was referred. On physical examination, the left hind limb was cold and there was no pulsation or mobility. On abdominal ultrasound examination, a thrombus 8 mm in length was found at the aortic bifurcation. The patient was diagnosed with hypertrophic cardiomyopathy (HCM) and cardiogenic pulmonary edema through radiologic evaluation and echocardiography. A tissue plasminogen activator (tPA) was applied intravenously using an accelerated dosing protocol (1 mg administered intravenously [IV] bolus, 2.5 mg IV over 30 min, 1.5 mg IV over 1 h) to treat the feline arterial thromboembolism. Within 12 h after administration of tPA, pulsation and mobility of both hind limbs were normal, without any noticeable complications. Clopidogrel was prescribed to prevent additional thrombus formation, and pimobendan, benazepril, and furosemide were prescribed for administration at home. The patient was discharged and survived 377 days.

  • A 2-year-old, female, Maltese dog (3.2 kg of body weight) was referred to the Veterinary Medical Teaching Hospital, Chungnam National University with vomiting, anorexia and depression. Twelve hours prior to the onset of clinical signs, the dog ingested some grape skins (about 60 g). Physical examination at the time of presentation showed peripheral edema and mucous pallor. Blood and blood chemical analysis revealed anemia and moderate azotemia with elevated blood urea nitrogen (107.2 mg/dl), creatinine (6.3 mg/dl) and hyperphosphatemia (11.3 mg/dl). Echogenicity of renal cortex were observred by ultrasonography. The dog was diagnosed as acute renal failure occurred by grape skin toxicosis. The dog was treated with supportive care such as fluid therapy, diuretics (furosemide) and phosphorus binder (almagate). A normal condition of blood and blood chemical findings and clinical signs was observed at five days after treatment, and prognosis is good to date.
