Platelet function in the racing thoroughbred: implication for exercise-induced pulmonary hemorrhage.

Platelet function was evaluated in horses with exercise-induced pulmonary hemorrhage (bleeder) and in control horses (nonbleeder). Platelet aggregation, secretion, and adhesion to rabbit aortic subendothelium were similar for bleeders and nonbleeders. Platelets readily aggregated in response to ADP, thrombin, collagen, and arachidonic acid, but platelet secretion occurred only with high concentrations of thrombin. Platelets readily adhered to rabbit aortic subendothelium and tended to form large thrombi rather than platelet monolayers or aggregates. These data suggest that horses may be predisposed to thrombus formation and subsequent microvascular obstruction.

Quantitative evaluation of echinocytes in the dog.

Echinocytes were evaluated quantitatively in both healthy and sick dogs and compared with red blood cell (RBC) morphology on Wright's-stained blood smears. Of 68 samples submitted from sick dogs, 32 had high echinocyte numbers. Two diseases, glomerulonephritis and lymphosarcoma, accounted for 15 of the 32 cases. In only four instances were echinocytes reported from blood smear evaluation and not found to be high by quantitative studies. We conclude that nonartifactual echinocytosis occurs in the dog and that it may be associated with specific diseases.
