Abstract
  1. Packed cell volume (PCV) and plasma catecholamines, cortisol and glucose were determined in blood samples obtained from race horses, after competition. 2. All these parameters were higher than basals but catecholamines increased 6-7 times while cortisol was enhanced only by 25%. 3. The increase of glucose and PCV was related to the rise of catecholamines. 4. In samples withdrawn after overnight stress caused by change of horseshoes, it was not possible to find values from basal values significantly different. 5. Influence of nervous temperament was observed only in the higher hematocrit found in basal conditions, particularly in females.
摘要
  1. 对比赛后的赛马采集血样,测定其血细胞比容(PCV)、血浆儿茶酚胺、皮质醇和葡萄糖含量。2. 所有这些参数均高于基础值,但儿茶酚胺增加了6 - 7倍,而皮质醇仅增加了25%。3. 葡萄糖和血细胞比容的增加与儿茶酚胺的升高有关。4. 在因更换马蹄铁导致过夜应激后采集的样本中,未发现与基础值有显著差异的值。5. 仅在基础状态下较高的血细胞比容中观察到神经气质的影响,尤其是在雌性中。
