| Autumn crocus poisoning of cattle is characterized by severe diarrhea caused by alkaloid colchicine. Previously, we examined pathologically this poisoning in cattle and reported that enterotoxic lesions were closely associated with apoptosis. To examine enterotoxicity of autumn crocus more precisely, a reproductive study was performed using guinea pigs and mice, and pathological findings associated with autumn crocus poisoning were compared with those of colchicine. Each group of guinea pigs given the bulb of autumn crocus or colchicine exhibited severe diarrhea. Histopathological findings in intoxicated guinea pigs were entirely consistent with those in the autumn crocus-poisoned cattle. In contrast, each group of mice administered with the bulb or... |

| 17日齢のホルスタイン種雌子牛が，神経症状を示した. 病畜は頭部を左後方に折り曲げて伏臥姿勢を示し，時折自力で起立したがすぐに倒れ歩行不能であった. 神経学的検査では右の対光反射，威嚇瞬き反射，眼瞼反射， および音響耳介反射が消失していた. ビタミンB1，およびデキサメサゾンの投与により第7病日に歩行可能となったものの左への斜頸・旋回が認められ，神経学的検査所見に改善は認められなかった. 第7病日に病理解剖を行い，肉眼的には橋の断面右側に直径1cm大の膿瘍を認め，嫌気培養にてFusobacterium necrophorumが検出された. 左側への斜頸，聴覚の消失等の脳神経疾状は，橋の右側の膿瘍により内耳神経等の脳神経核が圧迫された結果出現した聴覚障害，平衡障害のためと考えられた. A 17-day-0ld female Holstein calf exhibited the following neurological symptoms: the calf bent its neck to the left，turning its face backward and could stand alone，but would fall within a short time. Neurological examination further revealed losses of pupillary light reflex， menace response，palpebral reflex，and hearing on the right side. After administration of dexamethasone and vitamin B1，the calf was able to walk... |

| Computed tomography (CT) was used for diagnosis of brain abscess in a 6-month-old, Japanese black calf presented with neurological dysfunction, compulsive circling and vision disturbance. CT images showed asymmetric lateral ventricles, and presence of intra-cranial multiple low absorption lesions surrounded by capsule suggestive of abscess in the right cerebral hemisphere. Postmortem examination revealed marked swelling of right cerebral hemisphere and olfactory bulb. Multilocular large abscess containing creamy pus was found to occupy most area of periventricular and lateral ventricle. Fusobacterium necrophrum was isolated from the abscess contents as the causative agent. These results demonstrate that CT is useful tool for tentative diagnosis of bovine... |

| An 11-year-old Holstein-Friesian cow exhibited anorexia and jaundice. A large mass was found in the liver during necropsy. Macroscopically, the mass was composed of dark red multilobular tissue and a centrally located abscess, which was connected to the hepatic duct. Histologically, the mass consisted of proliferation of small neoplastic cells and was demarcated from the hepatic parenchyma by a thick region of granulation tissue. The neoplastic cells were predominantly arranged in solid sheets, but they also formed blood-filled cancellous structures, and proliferating foci were seen around blood vessels. Periodic acid-Schiff reaction demonstrated that a fine basement membrane-like structure surrounded the neoplastic cells. Immunohistochemically, the... |

| Humeral chondrosarcoma was found in an 18-year-old male Hokkaido brown bear (Ursus arctos yesoensis). Necropsy revealed a large firm mass under the left superficial pectoral muscle at the axillary region. The mass involved the left shoulder joint and peripheral muscles, and connected to the head of the humerus with osteolysis. Histopathologically, the mass was composed of irregularly shaped myxomatous to cartilaginous tumor lobules. The tumor cell showed moderate nuclear atypia with a relatively high mitotic index, especially in the edges of the myxomatous lobules. The tumor cells were positively immunostained with vimentin and S-100 protein. Based on these findings, the tumors were diagnosed as chondrosarcoma. Metastases were found in the left axillary... |

| 8カ月齢ホルスタイン種乳牛が起立不能を呈した.右下顎リンパ節相当部に腫瘤を認めたため，午白血病を疑い血液検査および針吸引細胞診を実施したが，確定診断に至らなかった.病理解剖においては，環椎および胸椎にも腫瘤が存在し脊髄を圧迫していた.病理組織学的に，腫瘍細胞はBLA-36抗原陽性であり，B細胞性リンパ腫と診断した. BLV抗体は陰性であった.これらのことから，本症例は非定型若齢牛の散発性牛白血病と考えられた. An 8-month-old Holstein heifer presented with difficulty in standing. Bovine leukosis was suspected because of the enlargement of the right mandibular lymph node; however，this could not be confirmed by fine needle aspiration of the lymph node and blood examination. A postmortem examination revealed that neoplastic masses compressed the spinal cord and nerves at the atlas and thoratic vertebra. A histopathological examination revealed the mass to be B-cell lymphoma based on BLA-36 positivity，but antibodies against bovine leukemia virus were not detected.... |
