第四胃変位手術前後に各6例のホルスタイン種乳牛について,血糖,血清総コレステロール,遊離脂肪酸(NEFA)およびアスパラギン酸アミノトランスフェラーゼ(AST),γ-グルタミルトランスフェラーゼ(γ-GTP)の活性値ならびにケトン体(3-ヒドロキシ酪酸とアセト酢酸)を測定した.ケトン体,NEFA,ASTは術前に高く,術後は低く,第四胃変位と血清ケトン体やNEFAの増加との関連が推測された.総コレステロールは手術前後に変化は認められず,γ-GTPは一定の変動傾向を示さなかった. --------------------日獣会誌 52,362〜365(1999)
Blood Chemistry Including Ketone Bodies before and after Surgical Operationin Cows with Abomasal DisplacementNoboru ITOH, Masateru KOIWA, Atsusi HATSUGAYA,Hiroshi YOKOTA and Takashi KUROSAWA
SUMMARY Blood chemical values including ketone bodies were measured before and after surgical operation in
6 each Holstein-Friesian cows with abomasal displacement. The increased and decrecased levels of aspartate
aminotransferase (AST), non-esterified fatty acid (NEFA) and ketone bodies (3-hydroxybutyric acid and
acetoacetic acid) were observed before and after operation, respectively, suggesting that the onset of
abomasal displacement was closely related to the increase of serum ketone bodies and NEFA. Total cholesterol
level was unchanged before and after operation, and no definite tendency could be found in γ-glutamyl
transpeptidase levels. --------------------J. Jpn. Vet. Med. Assoc., 52, 362〜365 (1999) |
