  • Title: [Ultrastructural morphometric analysis of adrenaline- and noradrenaline-containing cells in rat adrenals during physical and emotional stress].
    Author: Arefolov VA, Malikova LA.
    Journal: Biull Eksp Biol Med; 1983 Jan; 95(1):101-3. PubMed ID: 6681992.
    Abstract:
    Ultrastructural organization of chromaffin cells of rat adrenal glands was studied in different stress models (48 h of running in the wheel, 48 h of immobilization, and sleep deprivation during 7 days). It was shown by ultrastructural morphometry that chromaffin cells experienced fine structural modifications (a decrease in the number of adrenaline- and noradrenaline-containing granules, swelling of mitochondria and endoplasmic reticulum). The degree of such modifications depended on a stress situation, being more pronounced during physical stress.
