The effect of irradiation on platelet arachidonic acid metabolism

Journal Article · · Transfusion (Philadelphia); (United States)

Irradiation of platelets in vitro to 2000 rads did not alter arachidonic acid metabolism through the cyclooxygenase pathway. Production of platelet thromboxane B2 and 12-hydroxy-5,8-10-heptadecatrienoic acid remained similar in control and paired irradiated platelets. In paired samples the platelet lipoxygenase metabolite 12-hydroxy-5,8,10,14-eicosatetraenoic acid was significantly increased postirradiation to 42 +/- 2.8 percent when compared to a control value of 34.1 +/- 3.6 percent (p less than 0.02). Although this latter product has been demonstrated to be chemotactic for neutrophils, its role in platelet function has not been specifically determined.
