Effects of acute cerebral infarction on platelet ultrastructure (transmission electron microscope, × 20 000).
Golgi tubules and vesicles showed irregular arrangement in platelets from patients 1 day after infarction (B). These structures apparently increased in width and enlarged, compared with platelets from controls (A), in which Golgi internal structure is normal and regular. Arrows point to Golgi apparatus. Scale bars: 1 μm.
