| Abstract: | Rat platelets were isolated and labelled with 1-14C] arachidonic acid. After aggregation thromboxane B2, 12-hydroxy 5,8,10-heptadecatrienoic acid (HHT) and 12-hydroxy-eicosatetraenoic acid (12-HETE) were the main metabolites formed. A comparison was made between several properties of the platelets of adrenalectomized and sham operated rats. There was no difference in collagen-induced aggregation. The amount of 12-HETE and the sum of TxB2 and 12-HETE formed from endogenous arachidonic acid after aggregation was higher in the first group. |
