Arterial pressor responses and gastrocnemius muscle perfusion in LZR and OZR following intravenous infusion of the adrenoreceptor agonist phenylephrine (10 μg/kg) under control conditions and in response to pre-treatment with the α1/α2 adrenoreceptor antagonist phentolamine (10 mg/kg). Data (mean±SE) are presented for changes in mean arterial pressure (Panel A), femoral artery blood flow (Panel B) and vascular resistance across the gastrocnemius muscle (Panel C). * p<0.05 vs. LZR; † p<0.05 vs. OZR; n=6 animals under each condition.
