Representative findings of immunohistological staining of ED-1 positive interstitial macrophages. There was a significant higher number of infiltrating macrophages and also of other inflammatory cells in (a) 10% hydroxyethyl starch (HES) 200/0.5 compared with (b) 6% HES 130/0.42 and (c) Ringer's lactate (RL). Original magnification: × 200. ED-1 = marker for macrophage infiltration.
