Increased cyclic adenosine monophosphate (cAMP) levels in the spinal cord after phosphodiesterase 2A inhibition. Spinal cord slices were preincubated with BAY 60–7550 (1 μM) or vehicle, and stimulated with N-methyl-d-aspartate (300 μM). Note that the BAY 60–7550 pretreatment increased the cAMP levels. n = 7 per group. *P < 0.05.
