| To better understand the mechanism of excessive gas accumulation in the abomasum in bovine abomasal displacement, we performed gastric fluoroscopy in vagotomized cattle. Fifteen 6-month-old Holstein steers were divided into three groups: a non-vagotomized control group (Group C; n=5), a ventral thoraco-vagotomized group (Group V; n=5), and a dorsal and ventral thoraco-vagotomized group (Group DV; n=5). These groups were examined by fluoroscopy before and during a 5-week observation period after surgery. In Group C, no change was observed throughout the observation period. In Group DV, immediately after surgery, reticuloruminal motility was completely absent and ruminal distention was seen. Two weeks after surgery, abnormal reticulum motility and increased... |

| 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. |

| 19歳齢のペルシュロン種繁殖雌馬に血尿が認められた。血尿は止血剤および抗生剤投与によっては改善され なかった。患畜は次第に元気食欲の低下、削痩、貧血を呈し、高度蛋白尿および胸前部冷性浮腫が発現した。 直腸検査により人頭大に腫大した左腎を触知し、腎臓腫瘍を疑った。病理解剖の結果、左腎は27X18Xl0cmに 腫大し、血液に富む巨大な腫瘤形成(13X8X8cm)を認めた。左腎門リンパ節は腫大し、また右腎臓、左右 副腎、肝臓および肺では大小の白色腫瘤を認めた。病理組織学的検査によりこれらの腫瘍はいずれも浸潤性に 増殖する上皮性腫瘍組織であったことから、本症例は腎細胞癌が他の複数の臓器に転移したものと考察した。 |

| 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... |

| This study was designed to investigate gastrointestinal dysfunctions, especially the effects of gastrointestinal prokinetic agents on digestive disorders involving lowered motility. The effects of α2-adrenergic agonists for treating acute abdominal disorders involving intestinal torsion in horses were also investigated. The results are as follows: (1) It appeared that the functions of migrating contractions (MC) in horses were to transfer the contents of the digestive tract as soon as possible to the cecum and colon, in addition to maintaining homeostatis in the digestive tract. (2) Motilin was seen to be involved in the regulation mechanism of intestinal motility in the horse as well as in humans and dogs, and brought about MC. (3) The intravenous... |

| 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... |

| The effects of mosapride, a 5-hydroxytryptamine 4 (5-HT4) receptor agonist, on the motility of horse small intestine were examined by means of electrointestinography (EIG). Six adult healthy thoroughbreds were used, in which EIG signals from the small intestine were measured by a Degetorappar EGG system. Mosapride, dissolved in 200 ml water, was orally administered at a dose of 2 mg/kg. The total power of EIG signals at a frequency band of 3 cpm was 419.1 ± 122.0 (μV) 2 × cpm (n=6) before, and 2,093.6 ± 850.0 (μV)2 × cpm (n=6) after the drug administration, the latter mean value being significantly greater than the former. This result suggests that mosapride has a prokinetic action on the motility of horse small intestine. |

| The prokinetic effect of the 5-HT4 receptor agonist mosapride was evaluated in seven healthy thoroughbreds. Mosapride was orally administerd at doses of 0.5, 1.0 or 1.5 mg/kg. The breath 13CO2/12CO2 rate (Δ13CO2), an indirect indicator for the rate of gastric empting, was measured at appropriate points for 4 hr after drug administration. There was a significant increase compared with the control value at 15, 20 and 165 min for 0.5 mg/kg, 30 min at 1.0 mg/kg and 165 min for 1.5 mg/kg. The results suggest that mosapride may facilitate the gastric emptying in horses. |

| 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. |

| 十勝地区において疝痛を発症した馬３６頭を対象として、疝痛発症の危険因子および疝痛を発症した馬の予後 に関する疫学調査を実施した。調査の結果から、十勝地区における馬の疝痛発症には、過去の疝痛既往歴、駆 虫剤投与歴、飼養管理の急変などが関連していることが推測された。疝痛の種類別に来院時のヘマトクリット 値を比較すると、便秘疝の馬では変位疝や風気疝の馬と比較して有意に高値を示した。手術実施馬において、 疝痛発症から来院までの時間が長いほど予後が悪化する傾向がみられた。また、予後不良となった馬では術後 経過が良好で退院した馬と比較して、心拍数が有意に高値を示すということが判明した。 |
