A 4-year-old spayed female British shorthair cat was referred for abnormal pigmentation on the right iris. The pigmentation was mainly located in the medial portion of the iris. No abnormalities except iris were detected in a full ophthalmic examination. There was no evidence of metastasis after thoracic radiography and abdominal sonography. Enucleation was performed on the right eye and it was sent for a histopathological evaluation. It was confirmed as early stage of feline diffuse iris melanoma (FDIM) with involvement of iris stroma.

Antioxidant enzymes such as catalase (CAT), glutathione peroxidase (GSH-Px) and superoxide dismutase (SOD) are known to inhibit oxidative reactions by incativating compounds responsible for the formation of ree radicals. SOD transforms superoxide radical into hydrogen peroxide which is precursor to active free radicals. CAT reduces hydrogen peroxide to water. GSH-Px reduces hydroperoxides to corresponding alcohols. Antioxidant enzyme activities of muscle are different by animal species age, stress and exercise, muscle type and part, conditions of post mortem, storage and processing which are related to oxidative deterioration I muscle foods as well as oxidative defence in living systems. Antioxidant enzyme systems are enhanced rather than weakened in aging skeletal muscle. Red muscle contains higher antioxidant enzyme activity than white muscle. The antioxidant enzyme activities of poultry are higher in leg than in breast, and those of beef are higher in redder and more unstable muscles. It is clear that the effectiveness of the antioxidant enzyme in muscle foods seems to be influenced by meat processing operations. Both GSH-Px and CAT are inactivated by heat processing NaCl also influence the efficiency of the antioxident enzymes since its presence diminishes their catalyitc activity.

Patent ductus arteriosus (PDA) is a rare congenital cardiovascular anomaly in cats. Due to their small body, intercostal thoracotomy is the most common option to close the PDA. However, few reports detail the surgical technique for ligating PDA in kittens. In this case report, three cats weighing 1.4 kg, 1.2 kg, and 2.9 kg were diagnosed PDA. Clip ligation via left fourth intercostal thoracotomy was performed and the cats were successfully treated. Postoperative echocardiography showed no residual flow in any of the cases. This case report highlights clip occlusion for small cats with PDA could be safe and effective.

A 15-month-old, intact male, domestic short hair cat was presented with ataxia, protrusion of the right third eyelid, and anorexia. Clinical signs were firstly noted after ear cleaning at home. Symptoms of the Homer's syndrome were evident. However, postural and proprioceptive reaction deficits were not detected on neurologic examination. Otoscopic examination revealed foreign body in right ear canal. A diagnosis of peripheral vestibular syndrome was made based on results of physical examination including neurologic and otic examination, blood work, and magnetic resonance imaging (MRI). Based on these examinations, the present patient was definitely diagnosed as otitis medial interna induced by foreign body. The vestibular signs were resolved 10 days after removal of cotton tips in right ear canal. This case report indicates that home-care cotton swab can iatrogenically induce otitis media/interna in cats.

A 6-month-old, castrated male, Korean short-haired cat was referred with intermittent hematuria. Physical and laboratory examination including complete blood count and serum biochemistry profiles showed no specific findings. Ultrasonography revealed a cystic lesion of the mid-abdomen, which was approximately $2{\times}2cm$ in size. FNA cytology of cystic fluid showed numerous cholesterol crystals of varying size and shape and granulomatous inflammation. CT examination showed fluid-filled large cystic lesion in the left side of the abdomen. Taken together, this case was diagnosed as unilateral (left) renal dysplasia and cystic inflammation led by cholesterol crystallization in the left kidney.

Chemical carcinogen-induced alteration of aldehyde metabolic enzymes were examined in clone 9 cell. Diethylnitrosamine (DENA), N-nitrosoethylurea (NEU) and N-nitrosomorpholine (NNM) were wed as model carcinogens. Changes in enzyme activities by repetitive treatment of DENA, NEU or NNM were analyzed in terms of specific activities and activity stainings of the enzymes on the gel. Upon treatment of DENA, lipid peroxide level increased upto 10 fold, indicating strong oxidative stress state of the cell. Notable enhancement of ADH and ALDH activity occurred after DENA treatment, while glutathione-S-transferase activity was slightly increased. Furthermore, about 2.5 fold higher superoxide dismutase (SOD) activity was detected during deactivation of catalase (CAT) activity by repetitive treatment of DENA. However in NEU-treated cell, about 2.3 fold higher ALDH activity was found while ADH activity was slightly increased. Notable increase CAT and SOD could also be found. In contrast, maximum 3.5 fold higher CAT activity occurred during SOD deactivation in NNM-treated cell. These results suggest that there might be different enzymatic responses in relation to cell protection against DENA, NEU or NNM.

Lipid-lowering and antioxidant effects of Poncirus trifoliata extract were investigated in hyperlipidemic rat. Concentrations of FFA and triglyceride in plasma were decreased in Poncirus trifoliata extract treatment groups. Plasma total cholesterol and LDL-cholesterol were lower in Poncirus trifoliata extract treatment groups. However HDL-cholesterol showed no significant difference in all treatment groups. Concentrations of liver total cholesterol and triglyceride were decreased in Poncirus trifoliata extract treatment groups. Concentrations of plasma and liver TBARS showed a low values in Poncirus trifoliata extract treatment groups. The values of GSH-Px and CAT activities were increased in the Poncirus trifoliata extract treatment groups. However the values of SOD activity showed no significant difference in all treatment groups.

This study attempts to facilitate climate change adaptation in conservation area by spatial planning of climate adaptation zone for endangered species. Spatial area is South Korea and select leopard cat (Prionailurus bengalensis) as a target species of this study. In order to specify the climate adaptation zone, firstly, Maximum entropy method (Maxent) was used to identify suitable habitat, and then core habitat was selected for leopard cat. Secondly, land use resistance index was evaluated and least cost distance was analyzed for target species. In this step we choose dispersal capacity of leopard cat to reflect species ecological characteristic. Finally, climate adaptation zone is described and adaptation measures are suggested. The presented approach could be generalized for application into conservation planning and restoration process. Furthermore, spatial planning of climate adaptation zone could increase heterogeneity of habitat and improve adaptive capacity of species and habitat itself.

A 5-year-old castrated male domestic shorthair cat was referred for further investigation of pulmonary nodules incidentally detected on thoracic radiographs. Thoracic radiographs identified ill-defined soft tissue opacity nodules with small faint mineral opacity. Thoracic computed tomography (CT) revealed that bronchial dilation and bronchial wall thickening in bilateral cranial and accessory lung lobes. Round to ellipsoid mineralized concretions were found embedded in the intrabronchial soft tissue attenuation material. Based on radiography, CT, and cytology, the patient was tentatively diagnosed as having broncholithiasis with chronic bronchitis. This report described the CT diagnosis of broncholithiasis, which has been rarely reported in a cat.

Cellular automata (CA), which is known as a pseudo random number generator due to its excellent randomness, has various applications. Cho et al. designed a CA-based shrinking generator to generate a long period of nonlinear sequence. In addition, chaotic cat maps have been studied by many researchers as the complex nonlinear dynamics systems with sensitivity in initial conditions and unpredictable characteristics. In this paper, we propose a new image encryption method using nonlinear sequence generated by CA-based shrinking generator with maximum period and 3D chaotic cat map for high security.
