title: Abnormal release of storage pool adenine nucleotides from platelets of dogs affected with basset hound hereditary thrombopathy.
abstract: Platelets from dogs affected with Basset Hound Hereditary Thrombopathy (BHT), have a thrombasthenia-like aggregation defect but release storage pool ATP in quantities not significantly different from normal controls or BHT heterozygotes when stimulated with 1 X 10(-5)M ADP and 0.22 U/ml thrombin. However, the release occurs so rapidly in the BHT platelets stimulated with ADP that it is complete in approximately one-sixth of the time required for release from normal control and heterozygote platelets. Sequential electron micrographs reveal early release of BHT dense body constituents 30 seconds after stimulation with 1 X 10(-5)M ADP while resting BHT morphology is indistinguishable from normal control animals.
