[Aggregation of blood platelets and their energetic status in acute arterial hypertension].
The authors studied thrombin-induced aggregation of blood platelets washed clean of plasma and some parameters of their energetic status (content of ATP, ADP, and glycogen) in rats with acute vasorenal hypertension (AVH). Sensitivity of platelets to thrombin, the inductor of aggregation, was found to be increased and the initial aggregation in rats with AVN accelerated as compared to that in the controls. At the same time, the total adenine nucleotide content in platelets of rats with AVH was reduced--the ATP content by 33% and the glycogen content by 27%. The data obtained provide evidence that there is no correlation between the ATP and glycogen content in rat platelets and their ability for aggregation.
