Figure 1 Brachytherapy reduces acetylcholine (ACh)-induced vasoconstriction. Individual vessel diameter changes (with median values) after infusion with ACh before and after brachytherapy. Circles = first vessel and squares = second vessel before (open circles and open squares) and at follow-up after brachytherapy (solid circles and solid squares); second vessel in non-irradiated states at first investigation (open triangles) and follow-up after brachytherapy of first vessel (solid triangles). p indicates effect of brachytherapy.
