[The morphofunctional changes in human adrenals in death from acute alcoholic intoxication]

Area of Science:

• Endocrinology
• Toxicology
• Cell Biology

Background:

• Acute alcohol intoxication is known to affect various organ systems.
• The adrenal cortex plays a crucial role in stress response and hormone production.
• Lipid metabolism within the adrenal cortex is vital for its function.

Purpose of the Study:

• To investigate the effects of acute alcohol intoxication on adrenal cortex lipid composition.
• To characterize the cellular changes in adrenocorticocytes following alcohol exposure.
• To examine the relationship between lipid content and other cellular components like phospholipids and ascorbic acid.

Main Methods:

• Histological examination of adrenal cortex tissue.
• Staining techniques to identify sudanophilic and birefringent lipids (cholesterol and its esters).
• Microscopic analysis of adrenocorticocyte morphology and granule content.

Main Results:

• Complete delipidation of cholesterol and its esters observed in the reticular and bundle zones of the adrenal cortex.
• A clear, smooth horizontal interface demarcating lipid-depleted and lipid-rich areas.
• Accumulation of phospholipid granules in "dark" adrenocorticocytes, inversely proportional to cholesterol content.
• Significant decrease in ascorbic acid granules within cortical cells.

Conclusions:

• Acute alcohol intoxication induces rapid and widespread delipidation of the adrenal cortex.
• The observed changes in lipid, phospholipid, and ascorbic acid content suggest a disruption of adrenal function.
• These findings highlight the direct impact of alcohol on adrenal gland cellular integrity and biochemistry.
