A 10-year-old male beagle was referred to us with seizure related to hypoglycemia and a large intraabdominal mass. Based on various types of imaging and a laparoscopic biopsy, the intraabdominal mass was diagnosed as a hepatocellular carcinoma (HCC) of the quadrate lobe. The hypoglycemia was suspected to be associated with the HCC. After lobectomy of the quadrate lobe was performed, blood glucose levels continued to increase to higher than normal values and sugar was detected in the urine. The dog was diagnosed as diabetes mellitus (DM) and was treated with insulin for over two years after the surgery.  相似文献   

Seroepidemiological survey of morbillivirus infection in Kuril harbor seals (Phoca vitulina stejnegeri) of Hokkaido, Japan     

Fujii K  Sato H  Kakumoto C  Kobayashi M  Saito S  Kariya T  Watanabe Y  Sakoda Y  Kai C  Kida H  Suzuki M 《The Japanese journal of veterinary research》2006,54(2-3):109-117

Serological analysis was performed to detect morbillivirus infection in Kuril harbor seals in Hokkaido, Japan. Serum samples were collected from the seals at Nosappu (231 sera), Akkeshi (16), and Erimo (75) between 1998 and 2005. Antibodies to phocine distemper virus (PDV) were detected by ELISA in seals from Nosappu and Erimo. Antibodies to PDV were found in 56% (5/9) of the sampled seals from Nosappu in 1998, versus only 5% (3/66) for 2003, 1% (1/79) for 2004, and 1% (1/77) for 2005. These suggest epidemic caused by the virus in or before 1998. As antibody-positive seals included juvenile seals in 2003 and 2005, sporadic infections of the virus are thought to have occurred in recent years. In Erimo, antibodies to PDV were found in 50% (14/28) of sampled seals in 2004, versus only 13% (1/8) for 1999, 7% (1/15) for 2003, and 0% (0/24) for 2005. These suggest sporadic infection by the virus before 2003 and the epizootic between after autumn in 2003, when samples of 2003 were collected, and 2004. Since antibodies to canine distemper virus (CDV) were detected in one adult seal from Nosappu in each year from 2003 to 2005, sporadic infections of the virus were suggested. There were no difference in incidence of seals with antibodies to the viruses between males and females and between juveniles and adults.  相似文献   

MRI findings of haematomyelia in a dog with spontaneous systemic haemorrhage     

Okada M  Koie H  Kitagawa M  Kanayama K  Sato T  Yamamura H  Sakai T 《Australian veterinary journal》2006,84(9):332-335

A 7-year-old female cross-breed dog was brought to Nihon University Animal Medical Center for investigation of tetraplegia. Lameness in the pelvic limbs, that had developed 2 weeks previously, had progressed to tetraplegia. On magnetic resonance imaging of the spinal cord, isointensity was detected from C2 to C4 and T12 to T13, isointensity and hyperintensity were intermingled from L3 to L4, and hyperintensity was detected from L5 to L7 by T1-weighted imaging. On T2-weighted imaging, hyperintensity was detected in all regions described above. The dog recovered from anaesthesia, but died during the day from systemic bleeding as the result of a coagulopathy of unknown aetiology. Histopathological examination revealed haematomyelia in these regions of the spinal cord. This is the first report of magnetic resonance imaging findings of haematomyelia in canine spontaneous systemic haemorrhage. It appeared that the differences in the findings of T1-weighted imaging along the spinal regions reflected time-lags in the occurrence of bleeding.  相似文献   

Gastrointestinal helminths of feral raccoons (Procyon lotor) in Wakayama Prefecture, Japan     

Sato H  Suzuki K 《The Journal of veterinary medical science / the Japanese Society of Veterinary Science》2006,68(4):311-318

The population and distribution of feral raccoons (Procyon lotor) are expanding in Japan after escape or release from animal-owners. Wakayama Prefecture is one of the most typically devastated areas by this exotic carnivore, particularly in the last five years after a latent distribution for more than ten years. Official control measures of feral raccoons commenced in the summer of 2002 by several municipalities, and 531 animals collected in 12 municipalities between May 2003 and April 2005 were submitted for parasitological examination of gastrointestinal helminths. Detected parasites included six nematodes (Physaloptera sp. [prevalence; 5.1%], Contracaecum spiculigerum [0.9%], Strongyloides procyonis [25.5%], Ancylostoma kusimaense [0.8%], Arthrostoma miyazakiense [0.4%], and Molineus legerae [1.1%]), seven trematodes (Isthmiophora hortensis [4.9%], echinostomatid sp. with 34-39 collar spines [1.7%], Metagonimus takahashii [12.4%], M. yokogawai [0.8%], Plagiorchis muris [0.2%], Macroorchis spinulosus [1.9%], and Consinium ten [0.2%]), one cestode (Mesocestoides sp. [0.2%]), and six acanthocephalan spp. (Centrorhynchus bazalenticus [0.2%], Centrorhynchus teres [5.5%], Sphaerirostris lanceoides [2.4%], Plagiorhynchus ogatai [0.6%], Porrorchis oti [1.5%], and Southwelina hispida [1.9%]). Most of the collected parasites are food-borne, indigenous helminth species. Physaloptera sp. has never been recorded in indigenous wild carnivores in Japan, and resembles closely P. rara, prevalent in raccoons of North America, in morphology. The position of a pair of phasmids in the posteroventral region of the adult male, however, could differentiate it from P. rara. Since Strongyloides procyonis is known to cause creeping eruption as well as intestinal infection in a healthy human volunteer, we should be concerned about the rapid increase in the population and distribution of feral raccoons in Japan from the viewpoint of public health as well.  相似文献   

Immunohistochemical distribution of amyloid deposits in 25 cows diagnosed with systemic AA amyloidosis     

Yamada M  Kotani Y  Nakamura K  Kobayashi Y  Horiuchi N  Doi T  Suzuki S  Sato N  Kanno T  Matsui T 《The Journal of veterinary medical science / the Japanese Society of Veterinary Science》2006,68(7):725-729

The distribution of amyloid deposits was histopathologically and immunohistochemically examined in 25 cows aged 5 to 10 years that had been diagnosed with systemic AA amyloidosis. This examination revealed that amyloid deposits were also present in the hypophysis, ovary, uterus, mammary gland and skeletal muscle, in addition to the liver, kidney, spleen, pancreas, thyroid gland, adrenal gland, gastrointestinal mucosa, heart, lung and lymph nodes. The examined cows tended to have chronic inflammations, including chronic mastitis (six cases) or chronic pneumonia (four cases), which is thought of as a causative agent of AA amyloidosis. In contrast, five cases did not exhibit any chronic inflammation.  相似文献   

Molecular characterisation of equine group A rotavirus, Nasuno, isolated in Tochigi Prefecture, Japan     

Fukai K  Saito T  Fukuda O  Hagiwara A  Inoue K  Sato M 《Veterinary journal (London, England : 1997)》2006,172(2):369-373

In this study, equine group A rotavirus (RV-A), Nasuno, isolated from foal diarrhoea in Tochigi Prefecture, Japan was characterised genetically by sequence analysis of the genome segments encoding VP4 and VP7. The nucleotide and deduced amino acid sequences revealed high homology with P[12] RV-As (94.0-99.3% and 94.9-99.4%) and G3 RV-As (86.9-99.5% and 91.1-99.4%). Nasuno was also classified into P[12] and G3 in the phylogenetic analysis of the nucleotide sequences of the genome segments encoding VP4 and VP7.  相似文献   

Clone identification in Japanese flowering cherry (Prunus subgenus Cerasus) cultivars using nuclear SSR markers

Numerous cultivars of Japanese flowering cherry (Prunus subgenus Cerasus) are recognized, but in many cases they are difficult to distinguish morphologically. Therefore, we evaluated the clonal status of 215 designated cultivars using 17 SSR markers. More than half the cultivars were morphologically distinct and had unique genotypes. However, 22 cultivars were found to consist of multiple clones, which probably originate from the chance seedlings, suggesting that their unique characteristics have not been maintained through propagation by grafting alone. We also identified 23 groups consisting of two or more cultivars with identical genotypes. Most members of these groups were putatively synonymously related and morphologically identical. However, some of them were probably derived from bud sport mutants and had distinct morphologies. SSR marker analysis provided useful insights into the clonal status of the examined Japanese flowering cherry cultivars and proved to be a useful tool for cultivar characterization.  相似文献   

Anthracnose of bacopa caused by Colletotrichum destructivum     

Keisuke Tomioka  Toyozo Sato  Jouji Moriwaki  Yuichi Terasawa  Hiroki Koganezawa 《Journal of General Plant Pathology》2012,78(2):133-135

Severe spotting and blighting of leaves were found on bacopa (Sutera cordata), a scrophulariaceous ornamental, in greenhouses in Gunma Prefecture, Japan, from January through February 2007. After we isolated and identified the causal fungus as Colletotrichum destructivum and inoculated host plants with the isolate to confirm pathogenicity, we named this new disease anthracnose of bacopa.  相似文献

Spontaneous Gingivitis Related to Hair Penetration in Rats     

Aya Goto  Jiro Sonoda  Yuki Seki  Yoshikazu Taketa  Etsuko Ohta  Kyoko Nakano  Akira Inomata  Kazuhiro Hayakawa  Toyohiko Aoki  Kazuo Tsukidate  Satoru Hosokawa 《Journal of toxicologic pathology》2012,25(3):229-232

Maxillary gingivae from male and female Crl:CD(SD) rats at 12, 16, 21, and 34 weeks of age were examined histologically. The incidence of gingivitis was approximately 40%, with no age or sex predilection, and was most frequent between the first and second molar. Lesions were characterized by acute focal neutrophilic infiltration into the gingival mucosa, occasionally with inflammatory exudate. In severe cases, inflammation extended to the periodontal ligament with abscess formation, and adjacent alveolar bone destruction/resorption. The most characteristic finding was the presence of hair shafts associated with the lesion, which was observed in approximately 80% of the rats with gingivitis. These findings suggest that molar gingivitis occurs in rats from an early age and persists thereafter, and that the main cause of gingivitis in rats is hair penetration into the gingiva. It would be prudent to keep these background lesions in mind as potential modifiers in toxicity studies.  相似文献
