Table 1. Time to vessel occlusion by thrombus under varying conditions.

Case	Occlusion time
ADP injected (same as Begent and Born24,25).	340 s
No ADP injected.	380 s
No ADP injected and with blocking of ADP.	590 s
No ADP injected and with blocking of TB.	620 s
No ADP injected and with blocking of TxA2.	380 s
No ADP injected and with blocking of all agonists.	N/A; (Up to 1200 s.)

For all of the cases there was an injured site as shown in Fig. 1, and all unmentioned conditions were the same as for the case studied previously²⁴,²⁵. The first case of Begent and Born implies no agonists were blocked, an injured site was present and ADP was injected at the injured site.
