CAs were induced in 56 C57BL/6J mice divided equally into mice receiving vehicle only (DMSO), aspirin (25 mg/kg/day IP), Cox-1 inhibitor (Sc-560 10mg/kg/day IP), and Cox-2 inhibitor (NS-398 20 mg/kg/day IP). (1A, upper left graph) Aspirin and Cox-2 inhibitor did not alter the rate of CA formation in mice. (1B, upper right graph) Aspirin and Cox-2 inhibitor significantly reduced the risk of SAH in mice. (1C, lower graph) Aspirin and Cox-2 inhibitor significantly prolonged asymptomatic survival in mice.
