Cutaneous lymphoma is rare in cats. An 11-year-old spayed female Persian cat presented with crust, ulceration, and multiple nodules on the shoulder and forelimb for 2 months. Computed tomography revealed a diffuse, irregularly margined lesion in the dorsal cutis extending from cervical to thoracic vertebrae. Cytological evaluation predominantly revealed large round cells with multilobulated nuclei and basophilic cytoplasm. Histopathological examination confirmed round CD3+/PAX5-cells packed in the dermis. Thus, the diagnosis of non-epitheliotropic cutaneous lymphoma with a diffuse large T-cell type was made. The disease progressed rapidly for the next 2 weeks, and the owner elected humane euthanasia.

To understand antioxidant enzyme response of two contrasting Arundinella hirta ecotypes to drought stress, drought-tolerant Youngduk and drought-sensitive Jinju-1, were comparatively analyzed changes in the enzymatic activities of peroxidase (POD), ascorbate peroxidase (APX), catalase (CAT), superoxide dismutase (SOD), and glutathione reductase (GR). Two ecotypes, drought-tolerant Youngduk and drought-sensitive Jinju-1 were subjected to drought stress by withholding water for 12 days. ROS accumulation level and electrolytic leakage were significantly increased in both A. hirta ecotypes by drought stress treatment but less in Youngduk than Jinju-1. The RWC significantly decreased in both the drought stress-treated ecotypes as compared to control, but less in Youngduk than Jinju-1. Soluble sugar and protein content were increased more in drought stress-treated Youngduk as compared to Jinju-1. The activities of antioxidant enzymes such as SOD, CAT, POD, APX, and GR increased significantly in both the drought stress-treated ecotypes Youngduk and Jinju-1 as compared to control. The increase in antioxidant enzyme activity level was more prominent in drought stress-treated Youngduk as compared to Jinju-1. Taken together, these results suggest that Youngduk was more tolerant to drought stress than Jinju-1, and seem to indicate that tolerance of A. hirta to drought stress is associated with increased activity of antioxidant enzymes.

The purpose of this study is to investigate the major features of Next Generation Library Catalogs. 'Next Generation Melvyl Pilot' of University of California Library System and 'SearchWorks' of Stanford University Library are examined. While the former is developed, based on OCLC WorldCat Local, the latter is based on the Blacklight, an Open Source Catalog Software. Both commonly provide the features, including enriched contents, facet navigation, keyword searching, relevancy ranking of search results, and user contribution, etc., but some functions vary in scopes and contents. Also, it seems that both are in process of development rather than complete implementations.

A 1.5-year-old neutered male domestic short hair cat was presented with multiple nodular mass, and suspected mast cell tumor on the surface of the right ear, accompanied by submandibular lymph node involvement. Histopathological Examinations and KIT (CD117) immunohistochemical staining was performed after the surgical resection of the entire right ear pinna. This patient was diagnosed with an anaplastic mast cell tumor with a diffuse positive cytoplasmic expression of KIT. Imatinib mesylate was prescribed after surgical resection; the patient presented without recurrence or metastasis for 2 years. Mild leukopenia was observed as the only side effect of imatinib mesylate during medication.

Difference of learner speech and loanword phonology is investigated in terms of Korean learners' speech and their loanword adaptation of English words with a post-vocalic word-final stop. When we compared the speech of 12 Korean learners in mid-intermediate level with that of eight English speakers, the learner speech did not reflect loanword phonology of the vowel insertion after a voiced word-final stop (e.g., rib$[\dotplus]$, bad$[\dotplus]$, gag$[\dotplus]$ vs. tip[=], cat[=], book[=]), but, instead, the target phonology of vowel lengthening before a voiced word-final stop (e.g., rib[r.I:b], CAD$[k{\ae}:d]$, bag$[b{\ae}:g]$ vs. rip[rI.p], cat$[k{\ae}t]$, back$[b{\ae}k])$. A longitudinal study of learner speech before and after instruction showed some development toward the acquisition of target phonology. The results indicate that learner speech departs from loanword phonology, and approaches to target speech in a faster rate than direct ratio. Thus, native phonology predicts loanword phonology, but lends little support to learner speech. Our results also indicate that loanword phonology is constant, while learner speech changes toward the acquisition of target phonology.

Curcumin is widely used as a traditional medicine. This work was aimed to investigate its possible protective effect against chemically induced hepatocellular carcinoma (HCC) in rats. Fifty male albino rats were divided into five groups (n=10, each). The control group received a single dose of normal saline, the diethylnitrosamine (DENA) group received a single intra-peritoneal dose at 200mg/kg body weight, and the 3rd, 4th and 5th groups were given DENA and daily administrated curcunine (CUR) via intra-gastric intubation in doses of 300, 200 and 100 mg/kg b.wt. respectively for 20 weeks. Serum, and liver samples were used for determination of alpha feto-protein (AFP), interleukin-2 (IL-2), interleukine-6 (IL-6), serum liver enzymes (AST, ALT, ALP and GGT) levels as well the activities and gene expression of glutathione peroxidise (GPx), glutathione reductase (GR), catalase (CAT) and super oxide dismutase (SOD). Curcumin significantly lowered the serum levels of AFP, IL-2 and IL-6, ALT, ALT, and malondialdehyde (MDA) as well gene expression of IL-2 and IL-6. In contrast it increased the gene expression and activities of Gpx, GRD, CAT and SOD. The protective effect of CUR against DEN-induced hepatocarcinogenesis in albino rats was proven.

There has recently been a growing demand for pathodiagnosis to determine the cause of death in cats. We retrospectively analyzed the diseases diagnosed in cats that were submitted to Animal and Plant Quarantine Agency (APQA) in 2015~2017. Overall diagnostic rate in feline samples was 85.2% (n=104/122). Among diagnosed cases, infectious diseases (n=63) were responsible for most of the feline diseases and feline panleukopenia (n=29) were most prevalent. Highly pathogenic avian influenza (HPAI) H5N6 was first diagnosed in cats at the end of December 2016 in the HPAI outbreaks. One case in 2015, 4 cases in 2016, and 14 cases in 2017 were associated with animal abuse, such as trauma and poisoning. These results suggest that suitable vaccination of feline infectious diseases, monitoring of the susceptible domestic animals during HPAI outbreaks, and interest on veterinary forensics to prevent and determine animal abuse are needed.

Objectives : To investigate the effects of Cornu cervi parvum pharmacopuncture with regard to the blood picture and antioxidative activity in rats. Methods : Sprague-Dawley rats were divided into 3 groups (n=5 each) and were treated with Cornu cervi parvum pharmacopuncture every other day for 2 weeks. The groups are classified as follows; normal control without treatment (control group), Cornu cervi parvum pharmacopuncture at CV4 (CV4 group), and Cornu cervi parvum pharmacopuncture at BL23 (BL23 group). Thereafter, the blood and liver samples were obtained for blood analysis and superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GSH-Px) activity measurement. Results : Cornu cervi parvum pharmacopuncture groups showed higher values of red blood cell count and plasma cell volume compared with those of the control (p<0.05). However, hemoglobin level showed no significant differences among groups. With regard to the blood picture, plasma concentration in total protein and albumin showed no significant differences in pharmacopuncture groups, while higher ratio of albumin/globulin was observed in CV4 group. White blood cell counts and its composition showed no significant differences among groups. Pharmacopuncture groups showed higher values in SOD, CAT, and GSH-Px activities compared with those of control group. Conclusions : Cornu cervi parvum pharmacopuncture alleviates oxidative activities in rats.

An 11-month-old, 5.6 kg, grade 4 on a 5-point scale body condition score, castrated male Korean short hair cat was presented with right hindlimb lameness for 3 days without trauma. On physical examination, severe pain with crepitation was elicited at the hip region but not at the stifle. Radiographic examination and computed tomography revealed a Salter-Harris type 1 fracture of the femoral capital physis and dysplasia of the proximal tibial epiphysis. Spontaneous femoral capital physeal fracture was suspected and femoral head and neck osteotomy was performed. Treatment for proximal tibial dysplasia was not performed. On histopathologic examination of femoral head, a cluster of chondrocytes in a proliferative zone at the epiphyseal plate was observed. Therefore, spontaneous femoral capital physeal fracture was diagnosed. The patient recovered his gait, and no related clinical signs were observed during 6 months of follow-up.

The influence of various process parameters for the as-deposited poly silicon was investigated. The polycrystalline silicon films were successfully deposited on glass substrates at a low-temperature $(<200^{\circ}C)$ using the catalytic chemical vapor deposition (Cat-CVD). We achieved a low hydrogen content $({\sim}0.9%)$ and a high deposition rate $({\sim}35{\AA}/sec)$. The film is applicable to thin film transistors on plastic substrates.
