Influence of citrate concentration on the activation of blood cells in an in vitro dialysis setup

Fig 4

Representative scanning electron microscopy images of dialyzer fibers after in vitro dialysis in both citrate groups.

(a) On fibers from the 3 mM citrate group, occasional platelets and small platelet aggregates (top) or red blood cells and fibrin deposition (bottom) was detectable. (b) Fibers from the 4 mM citrate group appeared almost entirely clean (top), with very low numbers of adhering red blood cells (bottom). Scale bars represent 200 μm (overview) and 30 μm (insert).
