| カメの体幹部は甲羅に覆われているため、単純Ｘ線撮影では得られる情報が少ない。そこで今回、ミシシッピーアカミミガメに対するＸ線CTによる断層撮影検査の有用性について検討した。まず基礎的検討として、臨床的に健康な6匹を用い、軟部組織、肺および骨のCT値を計測し、その結果からそれぞれの組織の観察に適したウインドウを設定した。また、病理学的検索の結果、全ての個体において肝臓の脂肪変性が認められ、肝臓のCT値が低い個体ほど変性の程度が大きく、CT値の高い個体ほど変性の程度が小さかった。このことから、肝臓のCT値の差により脂肪変性の程度を診断することが可能であった。さらに、臨床例についてCT検査を実施したところ、それぞれ、消化管内異物、肺炎および卵塞の診断が可能であった。以上の成績より、ミシシッピーアカミミガメの臨床診断において従来の単純Ｘ線撮影では読影が困難であった体幹部軟部組織について、CTにより詳細な情報を得ることが可能であった。よって、カメの臨床診断にはCTによる断層画像診断の積極的な利用が望まれる。 In turtles，conventional radiographic techniques give little information on the interna1 organs because of the density of the shell. Therefore， computed tomography (CT) was attempted in six clinically normal red-eared sliders(Trachemys scripta elegans). The CT values were measured in soft tissues such as the... |

| Chondroitinase ABC (C-ABC) is expected to be a novel agent for chemonucleolysis. The effect of C-ABC was investigated by magnetic resonance (MR) and radiograph. C-ABC was administered into the lumbar intervertebral disks on the clinically normal beagles (n=5), in a dose of 50 μl (12.5 units as C-ABC). MR scans were performed pre-dose, and 1, 3, 7, 14 and 28 days after administration of C-ABC, and the signal intensity (SI) of the nucleus pulposus was measured. Radiographs were taken pre-dose, and 1, 2, 3, 4, 5, 6, 7, 14 and 28 days post-dose, to evaluate narrowing of the disk space in terms of height index (HI). In addition, the quantity of the chondroitin sulfate (CS) and the hyaluronic acid (HA) in the nucleus pulposus were measured by high performance... |

| We report here the non-contrast and contrast-enhanced computed tomography performed in two calves with brain abscess and multiple pulmonary abscesses with pharyngeal abscess, respectively. Contrast-enhanced computed tomography was useful in the diagnosis of these diseases in both calves. The diseases were confirmed by histopathological examination. |

| ベントナイトのセシウム体内移行抑制効果について調べた。実験には，ホルスタイン種子牛6頭を使用し，28日の実験期間中，全頭に安定同位体の塩化セシウム（3.0mg/kg/day）を人工乳に溶解し，投与した。塩化セシウムに加えベントナイト0.5w/v％を人工乳に懸濁した投与群（n=3）と塩化セシウムのみの対照群（n=3）の2群を設定した。実験開始0，1，2，3，7，14，21および28日目に採血，28日目に骨格筋，心臓，肝臓，腎臓および糞便を採材し，ICP-MS （inductively coupled plasma mass spectrometry） によるセシウム濃度を測定した。臓器中のセシウム濃度からベントナイトの効果は明らかではなかったが，血球中セシウム濃度平均値は投与後14日まで投与群が対照群よりも低値を示した。このことから，ベントナイトによるセシウム体内移行抑制効果の可能性が示唆された。 |

| To establish a method to predict postpartum diseases using prepartum back fat thickness (BFT), the peripartum BFTs of 54 healthy multiparous cows before calving, which were diagnosed with postpartum displacement of the abomasum (DA), clinical ketosis or subclinical ketosis were compared with those of healthy cows from 8 weeks before the expected calving date to 8 weeks after calving. The peripartum BFTs of the cows with DA or clinical ketosis were significantly higher than those of healthy cows. The peripartum BFTs of the cows with subclinical ketosis were not significantly higher than those of the healthy cows. |

| A 17-year-old, gray Thoroughbred gelding was presented with recurrent epistaxis following exercise for over one year. Multidetector-row computed tomographic (MDCT) examination of the head performed under general anesthesia indicated the presence of malignant melanoma. MDCT examination revealed the exact location and size of masses in the right guttural pouch first identified by endoscopy and in the left guttural pouch unidentified by endoscopy. MDCT examination revealed the presence of a blood clot that filled the right maxillary sinus. The horse was euthanized due to poor prognosis as a riding horse and the owner's decision, and MDCT findings were confirmed by postmortem examination. MDCT is suggested as a useful technique for diagnosis of head problems... |

| A cat was brought to us for the treatment of depressionanorexia，and hypovolemia. We performed an adrenocortkotropic hormone( ACTH) stimulation examination，radiography，ultrasonography，and computed tomography. On the basis of clinical symptoms，a low cortisol level，microcardia.small pulmonary vessels，and small adrenal glands. the condition was diagnosed as hypoadrenocorticism. Imaging findings were useful for obtaining additional infonnation on hypoadrenocorticism. Although hypoadrenocorticism in cats extremely rare， we would recommend its consideration as a differential diagnosis for cats with nonspecific clinical symptoms and hypovolemia. 元気消失，食欲不振を主訴とし，循環血液量低下を呈した猫にACTH （adrenocorticotropic... |

| 牛臨床におけるComputed Radiography (CR) の有用性を確立するため，管球-カセッテ間距離およびImaging Plate (IP) の読み取り時間が画質に与える影響について検討した.管球-カセッテ間距離は画質の視覚的スコア(粒状性，鮮鋭性)に影響しなかった. IPの読み取り時間は画質の鮮鋭性と相関しなかったが，粒状性と相関が認められた.しかし読み取り時聞が12時間以内の場合には問題にならない程度であると考えられた.管球-力セッテ間距離を再現よく保つことが難しく， IP読み取り時間のばらつきが想定される牛の臨床画像診断においてCRは有用なX線撮影システムであると考えられた. The purpose of this study was to investigate the effect of X-ray tube-cassette distance and image scanning time on image quality to establish the benefit of Computed Radiography (CR) in bovine clinical practice. The tube-cassette distance had no effect on the visual evaluation score (graininess and sharpness). The image scanning time correlated with graininess but not sharpness. From these results，it was concluded that accidental variations in the tube-cassette... |

| 腫瘍の犬3症例にハタケシメジ抽出物を投与し経過を観察した。肝腫瘍症例は投与開始から1カ月後に，直腸癌症例は9カ月後に死亡したが，脳腫瘍症例は23カ月経過した現在も生存している。ハタケシメジ抽出物の腫瘍に対する直接的な効果は不明であったが，3症例とも投与後に末梢血液中のリンパ球数が増加した。このことから，ハタケシメジ抽出物には犬の腫瘍症例の末梢リンパ球数を増加させる働きがある可能性が示唆された。 The clinical courses of three canine tumor cases were observed after administration of capsulated Hatakeshimeji extract (Lyophyllum decastes Sing.). The liver tumor case died one month after administration of the ectract，the rectal carcinoma case in nine months. but the brain tumor case is alive for 23 months. However it is unclear what directly effect the administration Hatakeshimeji has on a tumor，the number of lymphocytes increased after the administration of Hatakeshimeji in all thrεe cases. Therefore，it suggests that Hatakeshimeji plays a role in... |

| Platelet-rich plasma (PRP) was administered to cattle with hoof defects (10-mm drill hole) to promote sole defect healing. Two types of gels were prepared. One was a mixed gel [compound of gelatin microspheres (GM) incorporated with PRP and alginate] and was used for the test group, while the other was an alginate gel used for the control group. Each hole was filled with one of these gels. The drill hole depth, pressure pain, and hardness of the regenerated tissue were measured for 3 weeks after treatment. These measurements improved significantly in the test group than in the control group. The results suggest that a compound of GM incorporated with PRP and alginate had a hoof-regenerating effect in cattle. |

| 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... |
