Figure 3. Effects of (A) 2% enflurane (ENF), 2% halothane (HAL), and 2% isoflurane (ISO) and (B) 8% desflurane (DES) and 2% sevoflurane (SEV) on the endothelium-independent relaxation induced by sodium nitroprusside (SNP) in the presence of 100 micro Meter NG-nitro-L-arginine (n = 10-25). Where no error bar is shown, SEM falls within the dimensions of the symbol. CON = control.
