2歳5カ月齢ホルスタイン雌乳牛が胸垂冷性浮腫,頸静脈拍動を呈し,心音聴取困難および心電図各波低電位所見から拡張型心筋症が疑われた.右胸腔には赤色変性性漏出液が多量に貯留しており,また超音波検査により心嚢水貯留を認めた.病理解剖の結果,心嚢は直径60cm大に腫大して血様心嚢水の貯留を認めたが,炎症あるいは腫瘍は認められず,血様心嚢水貯留の原因については不明であった.ただし右肩部に壊死巣を認めたことから,転倒等胸腔に強い衝撃を受けた可能性があると考えられた.心嚢水貯留が認められる場合には,心嚢腔内への出血も考慮すべき疾病のひとつであることが考えられた. A Holstein cow (two years and five months old) with jugular vein distension and non-inflammatory edema in the brisket showed decreased heart sound and abnormal waves on an electrocardiogram. Dilated cardiomyopathy was suspected. Unilateral pleural effusion was recovered from the right pleural cavity and found to be degenerated transudations. An ultrasonic cardiogram detected pericardial fluid. A pathological examination revealed that the pericardial cavity was enlarged with a... |

The aim of this study was to clarify the relationship between the placental retention time (PRT) and the reproductive performance following mating at the foal heat in Thoroughbreds. For this purpose, we interviewed 292 farmers over a period of 3 years with questionnaires evaluating foaling, expulsion of placenta and reproductive performance at the foal heat in 1,432 mares. The obtained data were later compared with a previous study of heavy draft mares. The average of the PRT of the 1,432 Thoroughbred mares was 58 ± 88 min (mean ± SD). The mean PRT of Thoroughbreds was significantly shorter than that of the148 min of heavy draft mares. The incidences of retained placenta (RP) occurring in the Thoroughbred mares were 5.2 and 4.0%, for over 3 and 4 hr after... |

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. |

病理学的に血様液貯留を特徴とする特発性心嚢水腫と診断された乳牛8症例(血様心嚢水貯留群)の臨床病理学的検査所見を回顧的に取りまとめ,心膜炎7症例(心膜炎群)の所見と比較した.血様心嚢水貯留群では冷性浮腫を呈する症例が心膜炎群に比べて多かったが,その他の臨床症状には両群で差がなかった.心エコー検査では血様心嚢水貯留群では,心膜炎でみられる心嚢内の顕著なフィブリン析出はなかった.血液及び生化学検査では,血様心嚢水貯留群では炎症像が弱く,心膜炎群と比較して白血球数,分葉核好中球割合,A/G比,アルブミン濃度,γグロブリン割合に有意差がみられた.両群でALP及びGGTの高値がみられたが,特に血様心嚢水貯留群のGGT増加は顕著であった.血様心嚢水貯留症例の診断は臨床症状だけでは困難であるが,心エコー検査所見,弱い炎症像,ALP及びGGTの高値などが心膜炎との鑑別診断に有用と考えられた. Clinicopathological findings of eight cases of idiopathic hydropericardium characterized by bloodhlike fluid (HBFhgroup) that were confirmed by necropsy were retrospectively summarized and compared with those of seven cows with pericarditis. Although the numbers of cows that showed edema in the HBFhgroup were larger than those in the pericarditishgroup, the frequency of... |

The present study evaluated the effect of hemoplasmosis on cattle productivity. Prevalence of bovine hemoplasma was examined by polymerase chain reaction (PCR) using whole blood samples collected from 93 breeding cows and their 71 calves in Hokkaido, Japan. Monthly milk production records and other clinical data were compared between Mycoplasma wenyonii (Mw)-infected, “Candidatus Mycoplasma haemobos” (CMh)-infected, co-infected and PCR-negative groups. Blood chemical parameters were obtained from the 93 cows and 64 calves. PCR results showed that 89.2% (83/93) of cows and 14.1% (10/71) of calves were positive for bovine hemoplasma. Based on productivity data obtained from the 93 cows, Mw-infected, CMh-infected and co-infected cows had significantly lower... |

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... |
