A, a representative example of IBMX inhibitory effect on PDE activity in SANC lysate; B, PDE activity of SANC and LVC lysates in the presence and absence of IBMX; *p < 0.05, versus –IBMX, n = 4 to 7; C, Inhibition of total PDE activity in SANC and LVC by nimodipine (specific for PDE1), Ca2+-dependence of relative nimodipine-sensitive inhibition of total PDE activity; *p < 0.05, #p = 0.0343, n = 3 to 10.
