[Observation on ultrastructure of microvasculars in experimental cerebral ischemia].
Ultrastructure changes in microvasculatures were observed in cortical areas of cerebral post-ischemia. Mitochondria distention and endothelial swelling are first damage form in microvasculatures. A large number of pinosomes, damage of continuity of endothelial and basement membrane, membrane-bound intra-luminal bodies, narrow of lumen, compression of perivessels edema were considered as injury basis of microcirculation disturbance and edema in cerebral post-ischemia.
