Catalase Inhibits Dose-Dependently Platelet Aggregation Induced by Collagen But Not by ADP or Thrombin

	Control	Catalase (250 U/mL)	Catalase (1,000 U/mL)
Collagen (2 μg/mL)	63.2 ± 9.4	31.0 ± 11.2*	6.1 ± 1.4†
ADP (2 μmol/L)	52.7 ± 3.3	50.7 ± 4.7	44.0 ± 3.4
Thrombin (0.1 U/mL)	92.0 ± 3.1	91.0 ± 2.6	84.2 ± 2.5

	Control	Catalase (250 U/mL)	Catalase (1,000 U/mL)
Collagen (2 μg/mL)	63.2 ± 9.4	31.0 ± 11.2*	6.1 ± 1.4†
ADP (2 μmol/L)	52.7 ± 3.3	50.7 ± 4.7	44.0 ± 3.4
Thrombin (0.1 U/mL)	92.0 ± 3.1	91.0 ± 2.6	84.2 ± 2.5

The percentage of maximal aggregation 5 minutes after stimulation is shown. Data are expressed as the mean ± SEM of five separate experiments.
