JOURNAL FREE ACCESSIn June 2006, five goat kids showed signs of stumbling and astasia at a farm that kept 68 goats. Three of the five affected animals were submitted for examination. Virologically, the Caprine arthritis-encephalitis (CAE) virus gene was detected from the blood of one kid. The histopathological findings of the three animals, however, were different from those of CAE, and consisted of axonal degeneration of the spinal ventral root and central chromatolysis of the ventral horn neurons. The concentrations of copper in their livers and sera were very low. Based on these results, the disease was diagnosed as copper deficiency. The serum copper concentration survey of the remaining goats on the farm was low overall, but the copper concentration of the feeds was normal, so it was suggested that this disease wassecondary disease resulting from copper deficiency. Since this farm applied lime to the pasture soil in April 2006, we conducted a test lime application on the pasture to confirm the effect of liming on soil trace elements. Of the elements measured, the molybdenum concentration, which is known to affect the copper absorption of grazed animals, the limed pasture was higher than the nonlimed pasture at the end of the test. We therefore assumed thatthe 2006 liming might have been the major contributing factor to the present copper deficiency.View full abstractDownload PDF (1482K) -

JOURNAL FREE ACCESSThis paper is the first report of a horse with multisystemic eosinophilic epitheliotropic disease in Japan. A two-year-old male thoroughbred was admitted with anorexia and colic. The horse showed a remarkable increase in γ GTP, slight hypoproteinemia, hypoalbuminemia, and a lack of peripheral eosinophilia. The symptoms were not resolved with medical therapy. Exploratory laparotomy was performed, and a wall thickening and inflammation of theserous membrane on the small intestine were found. The horse was euthanatized with the diagnosis of perforation of the gastric ulcer two days after the laparotomy. White nodules were found in the pancreas at necropsy. Histopathologically, eosinophilic and lymphocytic infiltration as well as fibrosis were identified in the pancreas, liver, small intestine andlymph nodes (porta hepatic and mesenteric). The white nodules in the pancreas were eosinophilic granuloma. This case was histopathologically diagnosed as multisystemic eosinophilic epitheliotropic disease.View full abstractDownload PDF (3285K) -

JOURNAL FREE ACCESSThe purpose of this study was to document the incidence of canine tumors in Japan. During the period April 1985 to March 2006, 26, 072 dogs were referred to the Azabu University Veterinary Teaching Hospital. Of this number, 5, 819 dogs were diagnosed with a tumor. The 5, 819 canine neoplasm cases were analyzed by age, sex, malignant tumor rate, breed and site-specific tumor incidence. The average age of dogs with tumors was 9.2±3.3 years old.Cases with tumors were significantly older than general clinicalcases (6.1 ± 4.2 years) in dogs. The gender ratio was male 1: female 1.45, with female dogs showing asignificantly higher incidence than male dogs. The odds ratio, which reflects tumor incidence, washigher for Golden Retrievers (1.5) and Shetland Sheep Dogs (1.4), and significantly lowerfor Miniature Pinschers and Cavaliers. From the analysis of tumor incidence, malignancy rate, age, sex and canine breed for each specific site, we were able to confirm the statistical significance for each factor. Japanese canine breeds such as Shiba-inu and Kai-ken showed a significantly higher incidence of skin tumors, which included mast cell tumors. The odds ratio in Collies, Cocker Spaniels and Golden Retrievers for lymphoma was remarkably high in comparison with American reports. It was concluded that these results were useful clinical indicators for the diagnosis and treatment of canine tumors.View full abstractDownload PDF (926K) -

JOURNAL FREE ACCESSAfter a skin incision, spay and castration for rats, histopathological changes were compared against six different sutures widely used in the clinic. Spayed and castrated rats wereeuthanized at 30 days and 60 days after surgery, respectively. At necropsy, cutaneous fibrosis and yellowish masses of various sizes were observed in the spayed and castrated parts. Histopathologically, the lesions were characterized by various stages of foreign granuloma containing the suture materials. The inflammatory reaction wa more significant in spayed and castrated sites than in the sites of skin incision. Silk and absorbabl multifilamentsutures have produced the strongest tissue reaction among the tested suture materials. Theresults of the present study suggest that foreign granulomas occur with any suture, that tissue reactions continue as long as suture materials exist, and that the inflammatory response differs by suture materials and surgical site.View full abstractDownload PDF (4678K) -

JOURNAL FREE ACCESSThree foci of black crust-like lesions without thickening appeared in the dorsal skin of a15-year-old spayed female cat. Based on the initial diagnosis obtained from a skin biopsy, antiallergic treatment was attempted, but the skin lesions did not improve. The lesions changed into pigmentary thick plaques with an increase in their number. Total excision of the skin lesions was then performed, eighteen months after the initial diagnosis. Histopathologically, the skin lesions were diagnosed as squamous cell carcinoma in situ (Bowen-likedisease). Since cellular atypism and proliferative activity were not evident in the first biopsy specimens, neoplastic lesions may progress slowly over time. A new small focus appeared three months after the operation.View full abstractDownload PDF (2738K) -

JOURNAL FREE ACCESSAn atrial septal defect was diagnosed in an 11-year-old small male dog which was treated for mitral valve insufficiency over a period of five months. Continuous wave Doppler echocardiography revealed a left-to-right interatrial shunting flow with a maximal velocity of 3.5m/sec. With a worsening of the mitral valve insufficiency, the maximal velocity of interatrial shunting flow was elevated to 5.2m/sec. In spite of conservative therapy, the dog died after 86 days from left-sided heart failure. In the postmortem examination, a secundumatrial septal defect that measured 2 mm in diameter was detected. It was suggested that the hemodynamics of severe mitral valve insufficiency were unaffected by the small atrial septal defectView full abstractDownload PDF (1718K) -

JOURNAL FREE ACCESSTwo gentoo penguins (A, B) in a penguin aquarium showed symptoms of debilitation, anorexia, vomiting and hypochondria. Penguin A died in February 2007. Other penguins did not show any abnormalities. Three small pellets, two millimeters in diameter, were found in the abdominal cavity of A, andtwenty small pellets were found in B by X-ray examination. At necropsy of A, some slightly inflamed regions and two pellets were found in the stomach. Moreover, congestion and hemorrhaging were found in the intestinal mucous membrane of A. The lead level was 13.3±0.21ppm in the liver of A with an atomic absorption spectrophotometer, and the lead concentration in the serum of penguin B was 6.64 ppm. The pellets proved to be lead metal by X-ray qualitative analysis. The mean lead level was 0.007±0.003 ppm in the serums of the other four healthy penguins. The results suggested that the death and sickness were caused by lead poisoning.View full abstractDownload PDF (2280K)
