Abstract:
:Endothelial cells in biopsied blood vessels from von Willebrand factor (vWf)-deficient Doberman pinscher dogs contain immunologically detectable vWf. These dogs and normal dogs were treated with DDAVP (0.6 microgram/kg) and epinephrine (0.5 microgram/kg/min for 30 minutes) and were exercised, using 5 different exercise protocols, (3-4 m/s for 5-40 minutes at 0-5% grade) to determine if treatments reported to increase plasma factor VIII:C/vWf complex in humans would elevate canine plasma vWf. Following the two most strenuous exercise conditions--30 and 40 minutes--plasma von Willebrand factor antigen (vWf:Ag) increased in normal dogs by 30% and 70%, respectively. Factor VIII:C was increased 47% by the most strenuous exercise conditions. The vWf-deficient dogs would not exercise beyond 30 minutes and neither vWf:Ag nor factor VIII:C activity increased. Following DDAVP, plasma vWf:Ag increased in the normal dogs by 47% and factor VIII:C activity was increased by 48%. Factor VIII:C activity increased by 30% in the vWf-deficient dogs, but there was only a slight change in vWf:Ag. Bleeding time decreased in 5 of 6 vWf-deficient dogs. In the normal dogs vWf:Ag increased by 14% after epinephrine infusion, but factor VIII:C activity did not change; neither parameter was altered in the vWf-deficient dogs. While the factor VIII:C/vWf:Ag complex was increased in the normal dog by exercise and DDAVP, the increase is not as pronounced as has been reported for humans. It is not known whether the poor response of the vWf-deficient dog is due to low levels of vWf in their endothelium or to a release defect.
