Why the study?
The contributions of endothelium-dependent vasodilatory pathways beyond nitric oxide to the passive leg movement-induced hyperemic response had not been evaluated.
Does combined inhibition of NOS, cyclooxygenase, and CYP450 pathways further diminish the hyperemic response to passive leg movement compared with NOS inhibition alone?

Answers are grounded in this paper and cite their sources.
The hyperemic response to passive leg movement is primarily mediated by nitric oxide, with no significant additional contribution from prostaglandins or endothelium-derived hyperpolarizing factor.
Passive leg movement (PLM) evokes a highly nitric oxide (NO)-mediated hyperemic response and may provide a novel evaluation of vascular function. The contributions of endothelium-dependent vasodilatory pathways, beyond NO and including prostaglandins and endothelium-derived hyperpolarizing factor, to the PLM-induced hyperemic response to PLM have not been evaluated. With intra-arterial drug infusion, the combined inhibition of nitric oxide synthase (NOS), cyclooxygenase, and cytochrome P-450 (CYP450) pathways did not further diminish the hyperemic response to PLM compared with NOS inhibition alone.
