title: Ultrastructural changes in neurons of medullary giant-cell nucleus in growing rat exposed to acute stress.
abstract: Ultrastructural transformations in neurons of the medullary giant-cell reticular nucleus of young rats during exposure to acute emotional and painful stress attest to activation of the protein synthesis system (nucleolar hypertrophy, well-developed elements of the granular endoplasmic reticulum, increased content of free ribosomes and polysomes) in the majority of cells and the appearance of organelle injuries in some these cells.
