Figure 2 Forearm blood flow (FBF) response to three doses of sodium nitroprusside (SNP) following placebo or losartan administration for four weeks. Forearm blood flow is expressed as the percentage change in the ratio of infusion arm to noninfusion arm flows relative to the baseline period preceding the administration of SNP. Values are means ± SE. No change in SNP response was evident following losartan administration (p = 0.6, ANOVA; at each infusion rate p > 0.4, t tests).
