Abstract

Hemodynamic values were assessed in the cows diseased with mastitis. Hemodynamic testes were performed for white blood cell(WBC), red blood cell(RBC), packed cell volume(PCV), hemoglobin concentration, monocyte, eosinophil, neutrophil, lymphocyte, prothrombin time, activated partial thromboplastin time, thrombin time, fibrinogen, platelet concentrations, antithrombin-III and plasminogen activities. Significant alterations were observed in the mean values of most analytes. The numbers of monocytes, eosinophil, and neutrophil, and prothrombin time were increased while the number of lymphocyte, activated partial thromboplastin time, thrombin time, fibrinogen concentration, plasminogen activity and platelet concentration were decreased. The number of RBC, PCV, hemoglobin and antithrombin-III activity were unchanged compared with normal mean values. These data indicated that activation of hemodynamic mechanisms was initiated either directly by the endotoxin-releasing or indirectly by the inflammatory mediators released by response to etiologic agents. We suspected that the changes of hemodynamic values in the cows diseased with mastitis were very similar to those of experimental endotoxin-induced mastitis.
