7 Fig. 6 Cell ultrastructure changes of the cerebral cortex during operation.A, At 60 minutes of circulatory arrest, the majority of mitochondria were swollen and showed vacuolization (magnification × 15,000). B, At 30 minutes of reperfusion, all mitochondria were swollen and showed vacuolization, and some lanthanum granules were entering the cytoplasm and mitochondria (magnification × 20,000). C, In the CoQ10 group and at 60 minutes of circulatory arrest, a part of the mitochondria were slightly swollen (magnification × 8000). D, In theCoQ10 group and at 30 minutes of reperfusion, mitochondria were slightly swollen without remarkable vacuolization. Lanthanum granules were rarely seen entering the cytoplasm (magnification × 17,000). The Journal of Thoracic and Cardiovascular Surgery  , DOI: ( /uri:pii:S ) Copyright © 1994 Mosby, Inc.
