Table 2. Increase in Tissue cGMP Concentrations After Incubation of Intracranial and Extracranial Arterial Segments with Sodium Nitroprusside

Data presented as mean ± SD. Statistical analysis was performed using factorial analysis of variance and post hoc  Bonferroni–Dunn test.

*Significant difference between intracranial and extracranial vessels.

†Significantly different from baseline and 10–9 m sodium nitroprusside (SNP).

‡Significantly different from baseline and 10–7 m SNP.

cGMP = cyclic guanosine monophosphate.
