A 2 months old female Korean domestic shorthair cat weighing 1.2 kg was come to hospital because of respiratory discomfort and lethargy. Heart sounds was more intense and clear on the right side than the left. On radiographic views, loss of the normal diaphragm line, undistinguishable shadow of heart, shadow of gas-containing intestines could be observed in thoracic cavity. Diaphragmatic herniorrhaphy was performed by using propofol 8 mg/kg IV and isoflurane without any complication. On 7th day after the operation, almost all the clinical signs and radiographs including diaphragmatic line, cardiac silhouette, liver and small intestines were turned to normal.

A 7-year-old castrated male domestic short-hair cat presented with anorexia, constipation, depression, and voice alteration. Physical and neurological examinations revealed hyperthermia ($40.5^{\circ}C$), ventroflexion of the neck, reduced responses to external stimuli, generalized muscle weakness, and exercise intolerance. Thoracic radiographs revealed the presence of a cranial mediastinal mass. The history, clinical signs, and other examination results were compatible with acquired myasthenia gravis (MG). Acetylcholine receptor (AChR) antibody titers were determined to confirm MG and the serum AChR antibody concentration was 1.24 nmol/L (reference interval, < 0.3 nmol/L). This is the first diagnosis of acquired MG in a cat in Korea.

Promoters of an alkali-tolerant Bacillus sp. isolated from soil have been cloned in Bacillus subtilis using promoter probe vector pPL703. The CAT specific activity of a clone harboring the strongest promoter activity among these transformants was 8.01. This activity was 2.5 times higher than that of Bacillus subtilis harboring expression vector pPL708 and was increased after the end of the logarithmic growth phase. In the 2.8kb of inserted DNA fragment, BamHI and Sal I recognition sites were located.

In this paper, we describe a method for synchronization protocol method used in control system based on network and IEEE 1599 synchronization method which used for implementation of synchronization technology of advanced industrial Ethernet. We also implement and perform the experiment for synchronization technology of EtherCAT communication which is one of the industrial Ethernet technology used IEEE 1599 synchronization technology based on time. And we describe an evaluation for experiment result, improve the problem and future plan.

An approximately 8-month-old, 2.61 kg, male Siamese kitten was referred with primary complaints of a 1-week history of respiratory distress, exercise intolerance and dyspnea. Diagnostic studies identified III/VI systolic murmur in the cardiac auscultation, right ventricular enlargement patterns in the electrocardiogram, pleural effusion and right-sided cardiomegaly in the thoracic radiography, and right marked ventricular dilatation, right atrial enlargement, atrial septal defect and abnormal left atrium divided by fibromuscular membrane. Based on these findings, the case was diagnosed as cor triatriatum sinistrum complicated with an ostium primum atrial septal defect. The cat was rescued with furosemide, nitroglycerine, oxygen supplement and fluid removal from pleural cavity.

We previously shown that sphingosylphosphorylcholine, a lysophosphatidic acid, produced contraction in isolated single cells of cat ilium. We investigated the mechanism of sphingosine-1-phosphate (S1P)-induced contraction of circular smooth muscle cells in cat esophagus. S1P produced esophageal contraction in a dose dependent manner. The maximal contraction (l0$\^$-7/ M) induced at 1min. Pertusis toxin (PTX) inhibited contraction induced by S1P, suggesting that the contraction is mediated to a PTX-sensitive G-protein. (omitted)

[6]-Gingerol, a major polyphenol of ginger (Zingiber officinale), exhibits a variety of biological properties including anti-oxidant, anti-inflammatory and anti-cancer activity. However, the radioprotective effect of [6]-gingerol is still unknown. The aim of this study was to investigate the radioprotective effect of [6]-gingerol against radiation-induced cell cytotoxicity and oxidative stress in HepG2 cells. [6]-Gingerol pretreatment attenuated radiation-induced cell cytotoxicity caused by 5Gy (half lethal dose, $LD_{50}$ of HepG2 cells). The measurements of superoxide dismutase (SOD) and catalase (CAT) activity were also performed. The results showed that [6]-gingerol pretreatment reduced increasing SOD and CAT activity after exposure of IR, indicating that [6]-gingerol protected oxidative stress by regulating cellular antioxidant enzyme (SOD and CAT) activity. These findings suggest that [6]-gingerol acts as a radioprotector by attenuating cell cytotoxicity and oxidative stress.

A 10-month-old intact male Scottish Fold was presented with cardiomegaly. The cat showed exercise intolerance after birth. Radiographs showed cardiomegaly with bulging of the main pulmonary artery and dilation of pulmonary arteries. Echocardiogram revealed abnormally arisen aortic root toward right ventricle with left-to-right shunted perimembraneous ventricular septal defect located underneath the aortic root. Based on imaging studies, the cat was diagnosed as subaortic type of double outlet right ventricle (DORV) without concurrent abnormalities.

A 12-month-old, 3.0-kg, male, Scottish fold cat was referred to Irion animal hospital with dyspnea and cardiac murmur. In radiograph, right-sided cardiomegaly and pleural effusion were identified. In echocardiographic examination, abnormal stenotic region was identified in right ventricle and dilation of right atrium and concentric hypertrophy of interventricular septum and the free wall of right ventricle were also identified. In the stenotic region, abnormal muscular band was identified. The turbulent flow was identified in infundibular region of right ventricular outflow tract with color-Doppler examination and high velocity flow (4.0 m/s) was also identified in stenotic region. With these results, double-chambered right ventricle (DCRV) was diagnosed.
