[Some ultrastructural aspects of the cardiac muscle of albino rat during the acute stress produced by formaldehyde (author's transl)]. / Alguns aspectos ultra-estruturais da fibra muscular cardíaca do rato albino sob a influéncia do "stress" agudo provocado pelo formol.

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.

[Pulmonary ultrastructural changes in dogs following experimental hemorrhagic shock (author's transl)]. / Alterações da ultraestrutura pulmonar provocadas pelo choque hemorrágico. estudo experimental em cães.

The authors have studied the ultrastructure of the lung in dogs following experimental hemorrhagic shock. They found intra-alveolar edema, red cells in the alveolar sac, disappearance of the substance of the lamellated osmiophilic bodies and cellular degeneration. Correlation among these alterations and increase of capillary permeability as well as consumption of surfactant secretion were established.
