Change in M/C ratio after stimulation with the endothelium-dependent vasodilator serotonin (a), NO inhibitor L-NMMA (b) and the endothelium-independent vasodilator SNP (c) before (white circles) and 4 h (black circles) and 7 days (diamonds) after rHDL infusion in type 2 diabetes patients as well as in control volunteers (before, white triangle; after 4 h, black triangle). ^bp < 0.05 for type 2 diabetes patients compared with control individuals and ^ap < 0.05 for changes after rHDL within type 2 diabetes patients.
