Hematologic and rheologic changes were examined in 49 Thoroughbreds before and after competitive racing. Mean postrace values for RBC count, hemoglobin concentration, and PCV increased by 58 to 61%, whereas blood viscosity increased 2 to 3 times. Postrace echinocyte numbers were 162% greater than prerace values. Smaller, but statistically significant, changes were found for mean corpuscular hemoglobin concentration, red cell distribution width, plasma total protein concentration, total WBC count, neutrophil count, and lymphocyte count. Variables measured did not predict whether a horse was a bleeder not treated with furosemide, a bleeder treated with furosemide, or a nonbleeder.
对49匹纯种马在参加比赛前后的血液学和流变学变化进行了检查。赛后红细胞计数、血红蛋白浓度和红细胞压积的平均值增加了58%至61%，而血液粘度增加了2至3倍。赛后棘形红细胞数量比赛前值高162%。平均红细胞血红蛋白浓度、红细胞分布宽度、血浆总蛋白浓度、白细胞总数、中性粒细胞计数和淋巴细胞计数也有较小但具有统计学意义的变化。所测量的变量无法预测一匹马是否为未用速尿治疗的出血者、用速尿治疗的出血者或非出血者。
