  • Cat scratch disease is a zoonotic disease usually caused by the gram-negative bacterium Bartonella henselae. It is transmitted commonly by scratch or bite from cats or kitten. Cat scratch disease typically affects children and young adults, who develop regional lymphadenopathy. In contrast, in immunocompromised hosts, bacteremia may occur, bacillary angiomatosis and bacillary peliosis hepatitis or splenitis are the most common manifestations. Bartonella henselae was detected in three of thirty veterinarians and Bartonella clarridgeiae was detected in one of thirty veterinarians by a novel nested polymerase chain reaction. Cat scratch disease will not be neglected, and it needs continuous studies as well as observation and prevention of this disease.

  • Cellular automata are discrete dynamical systems, which provide the basis for the synthesis of complex emergent behavior. This paper proposes a new algorithm of digital watermarking based on cellular automata transform (CAT). The idea of two-dimensional CAT is introduced into the algorithm. After the original image is disassembled with 2D CAT, the watermark information is embedded into the Middle-frequency of the carrier picture. Cellular automata have a huge number of combinations, such as gateway values, rule numbers, initial configuration, boundary condition, etc. Using CAT, the robustness of the watermark will be tremendous strengthened as well as its imperceptibility. Experimental results show that this algorithm can resist some usual attacks such as compression, sharpening and so on. The proposed method is robust to different attacks and is more security.

  • Acorenone, a diterpene isolated from Acorus gramineus, showed strong resistance inhibitory activity against multi-drug resistant microorganisms such as Staphylococcus aureus SA2, which has resistance to 10 usual antibiotics including chloramphenicol (Cm). At the level of $5\;{\mu}g/ml$ when combined with $50\;{\mu}g/ml$ of Cm. Bacterial resistance to Cm is due to the presence in resistant bacteria of an enzyme, chloramphenicol acetyltransferase (CAT), which catalyses the acetyl-CoA dependent acetylation of the antibiotic at C-3 hydroxyl group. To elucidate the mechanism of resistant inhibitory effect, the acorenone which had the strongest resistant inhibitory activity, was investigated on the CAT assay. As the result, the combination of Cm and acorenone showed the strongest inhibitory activity on CAT as noncompetitive and dose dependent manner.

  • A 3-month-old, female Persian cat was presented with sclera mass. The mass was detected after cat's squeals during the playing with a dog before 2 days. On ophthalmic examination, a $2{\times}5mm$ dark purple colored raised mass was observed 1 mm behind the limbus in the right eye. Anterior chamber was filled with blood and epithelial defect was detected at 2 o'clock in the right central cornea. After general anesthesia, resection of the protruded iris was performed with iris scissors and bipolar cautery. Ruptured sclera and conjunctiva were closed with simple interrupted and simple continuous suture, respectively. Also, irrigation and aspiration (I/A) of the anterior chamber was performed to remove blood clot with bimanual I/A handpiece in the right eye. Four months after the surgery, the right eye was recovered completely and menace response was positive in spite of the retinal lesions.

  • In this paper, we propose on image encryption method which uses NC(Non-linear Cycle) and 2D CAT(Two-Dimensional Cellular Automata Transform) in sequence to encrypt medical images. In terms of the methodology, we use NC to generate a pseudo noise sequence equal to the size of the original image. We then conduct an XOR operation of the generated sequence with the original image to conduct level 1 NC encryption. Then we set the proper Gateway Values to generate the 2D CAT basis functions. We multiply the generated basis functions by the altered NC encryption image to conduct the 2nd level 2D CAT encryption. Finally, we verify that the proposed method is efficient and extremely safe by conducting an analysis of the key spatial and sensitivity analysis of pixels.

  • Neisseria (N.) animaloris is a common flora in animals, but its pathogenicity is rarely reported. In this case report, N. animaloris was isolated from a hospitalized cat with pneumonia. The cat was discharged after testing and treatment with appropriate antibiotics. This paper reports the first case of N. animaloris pneumonia in Korea.

  • A 14-year-old castrated male Persian cat presented with a 2-week history of respiratory difficulty. On physical examination, the patient showed intermittent open-mouth breathing and thoracic auscultation revealed wheezing. Thoracic radiographs revealed a narrowed upper airway and pulmonary infiltration. Computed tomography detected a mass occluding the lumen of the trachea at the level of the entrance to the thorax, a mass causing right main bronchus stenosis, and a nodule on the right caudal lung lobe. Bronchoalveolar lavage cytology tentatively diagnosed a carcinoma. Tracheal mass resection was performed through tracheostomy. Histopathology confirmed the presence of tracheobronchial carcinoma. The survival time after diagnosis was 10 months, during which time the cat underwent tracheostomy, debulking by endotracheal tube, and tracheal stent placement procedures in combination with toceranib phosphate adjuvant chemotherapy.

  • A four-month-old intact femlae Abyssinian cat was present for routine health evaluation, because her littermate was recently died of ventricular septal defect. Diagnostic imaging studies showed a large caudal paracardiac mass in thoracic radiography and homogenous mass adjacent to heart in the echocardiography. Further echographic study revealed that the mass was liver and the diaphragmatic line was intact. The positive contrast celiogram revealed that no extravasation of the contrast media across the diaphragm and the prolapse of diaphragm into the pleural cavity. Based on our diagnostic imaging studies, the case was diagnosed as diaphragmatic deformity in a cat mimicking a cardiac mass.

  • At the time of visiting, the cat was 6-year-old female Siamese cat. The mammary mass was solid and firm and measured $2{\times}5cm^2$ in greatest diameter. The uterus revealed thick uterine horn and cross sectioned wall. Histopathologically, the mammary mass revealed feline mammary carcinoma. In the uterus, cystic endometrial hyperplasia was observed. Feline leukemia virus positive reaction was detected by polymerase chain reaction. As far as we know, this is the first report of the simultaneous feline mammary carcinoma and uterine endometrial cystic hyperplasia with Feline leukemia virus infection in a cat.

  • A seven-year-old, castrated male, Korean domestic shorthair cat was referred because of a kidney abnormality. Radiography revealed left renal agenesis and right kidney enlargement. Ultrasonography and computed tomography (CT) showed amorphous calcified materials in a cyst-like lesion of the right kidney. In the excretory phase of the CT images, the lesion was opacified with contrast materials, indicating communication with the collecting system. Based on these findings, the cat was diagnosed with a calyceal diverticulum. A calyceal diverticulum may cause various clinical symptoms related to the urinary system. The excretory phase of CT is useful for diagnosing a calyceal diverticulum.
