[Some ultrastructural aspects of the cardiac muscle of albino rat during the acute stress produced by formaldehyde (author's transl)].

: The authors studied ultrastructurally the influence acute stress, produced by formaldehyde, has on some aspects of the cardiac muscle metabolism in albino rats. The results showed that the cardiac muscle was induced to develop additional work, represented ultrastructurally by an increase in the number of lipid droplets and increased concentration and volume of mitochondria.
