Familial renal amyloidosis was found in a four-year-old male Shar Pei dog. The dog had intermittent fever with signs of renal failure. Another sibling of this dog also showed subclinical signs of renal amyloidosis. Despite aggressive therapy with peritoneal dialysis, the dog died after 10 days of the first presentation. With special staining for amyloid, the renal amylodosis was confirmed.

The choice of input distribution in quantitative risk assessments modeling is of great importance to get unbiased overall estimates, although it is difficult to characterize them in situations where data available are too sparse or small. The present study is particularly concerned with accommodation of uncertainties commonly encountered in the practice of modeling. The authors applied parametric and non-parametric bootstrap simulation methods which consist of re-sampling with replacement, in together with the classical Student-t statistics based on the normal distribution.

Swine influenza is an acute, infectious respiratory disease caused by type A influenza viruses in pigs. In the previous studies, serological surveys have indicated the presence of H3N2 swine influenza virus (SIV) since 1995 in Korea. And the percentage of the antibody-positive rate was 39.12% in the survey determining the prevalence of H1N1 SIV antibodies in 2002. The purpose of this study was therefore to investigate the sero-prevalence of SIV regard to the age of the pig and the season between June 2004 and May 2005. In this study, a total of 932 sera were used.

The occurrence of hydropericardium-hepatitis syndrome was confirmed for the first time in Korea from chickens submitted for diagnosis to our laboratory from broiler and baeksemi farms. Clinical signs included depression, inappetence, ruffled feathers and an increase in mortality. At necropsy, severe hydropericardium and hepatic necrosis was characteristically found. The most remarkable microscopic changes were seen in the liver, including basophilic intranuclear inclusion bodies in the hepatocytes, massive hemorrhages and necrosis in the liver parenchyma.

Neoheterobothrium hirame (N. hirame) is a large blood-feed gill-worm infecting the highly prized olive flounder. The present study was reported the occurrence and elimination of Neoheterobothrium infection from young cultured oliver founder in the western coast of Korea. Flounder (weight 18-25 g, length 10-15 cm) were obtained from a cultured farm at Taean of Korea at May 2006. A lot of flounder died with serious anemia. We isolated N. hirame from the buccal cavity wall of dead flounder. Adult parasites were 5-15 mm in total length, with 4 pairs of clamps on the pedunculated haptor and isthmus region embedded in host tissue, while immature and sub-adults were identified the attachment to the gill filaments, rakers and arches with the clamps.

Pneumocystis (P.) carinii is an opportunistic fungal pathogen of many animal species and human, which can cause fatal pneumonia in immunocompromised individuals. Three 100-day-old pigs with progressive atrophy, anorexia and respiratory distress were submitted to the Cheju National University for diagnosis. Grossly, the lungs were enlarged with rubbery consistency. Histopathologically, the lungs were characterized by diffuse interstitial pneumonia with thickening of alveolar septa due to infiltration of macrophages and lymphocytes.

A two-year-old intact male Miniature Schnauzer was presented with signs of anorexia and abdominal pain with six-week duration. An exploratory ventral midline laparotomy was performed for a confirmative diagnostic and therapeutic purpose, and the presence of a string gastrointestinal linear foreign body was observed originating in the stomach, extending to the ileum. In the small intestine, the linear foreign body was located in the serosal layer. A partial enterotomy was performed on the mesenteric border of the intestine and the string was removed.

This study was conducted to investigate the pathogenicity of Paenibacillus (P.) polymyxa JB115 and single oral dose toxicity of culture broth containing β-glucan (CBG-JB115) produced from P. polymyxa JB115 in Sprague-Dawely rats of both sexes for 14 days. After oral administration of P. polymyxa JB115 into rats, we could not find any abnormal clinical signs and variation in the body weight and temperature as compared with control group. We also investigated the acute toxicity of CBG-JB115. As the results, there were no clinical signs and variance in the body weight and temperature related with CBG-JB115 in comparison with the control group.

A 6-year-old female Maltese dog (body weight 2.0 kg) was referred to the Veterinary Teaching Hospital. Kangwon National University with primary complaints including exercise intolerance and heart murmur. Based on clinical and diagnostic findings including grade V/VI left basal continuous murmur, bounding femoral pulsation, left ventricular enlargement pattern in electrocardiogram, cardiomegaly with aortic bulging on the thoracic radiography, and shunt flow between aorta and pulmonary artery on the echocardiography, the dog was diagnosed as the left-to-right patent ductus arteriosus.

This study was performed to investigate the effects of urinary acupoint (BL-23, BL-28) by acupuncture (AP) and electroacupuncture (EA) on urinary bladder in dogs. Four healthy male dogs aged within the range of 6~8 months were used in this experiment. For Electrodes implantation on the bladder, dogs were to undergo surgical operation. The purpose of investigating the effect on urinary bladder was to evaluate electromyogram (EMG) changes according to AP or EA at Shen Shu (BL-23), Pang Guang Shu (BL-28) and non-acupoint.
