Figure 4: Angiographic and Doppler Changes in L-NAME Group Versus Other Groups

Changes in angiographic diameters and Doppler flow parameters before and after needle injury (pre-treatment) in the L-NAME group pigs versus the other groups not pre-treated with L-NAME (combined for the sake of comparison). Note the percentage change in angiographic diameter, VTI, and Vmax is not different between the groups. Abbreviations as in Figures 1 and 2.
