Summary
Hydrofluoric acid (HF) burns cause lung thrombosis, a key factor in fatalities. This study reveals HF-induced endothelial injury and platelet aggregation in mouse lungs, explaining severe outcomes.
Area of Science:
- Toxicology
- Pathology
- Materials Science
Context:
- Hydrofluoric acid (HF) use is increasing in electronics and petrochemicals.
- HF causes severe, penetrating burns to organic tissues.
- High-concentration HF burns can be fatal, leading to lung edema and systemic injury.
Purpose:
- To investigate the pathological mechanisms of hydrofluoric acid (HF) burns.
- To conduct histopathological and ultramicroscopic experiments on HF-induced injuries in mice.
- To identify the primary causes of death following HF exposure.
Summary:
- Histological examination revealed lung thrombosis in mice exposed to HF, correlating with higher mortality rates.
- Ultrastructural analysis showed platelet aggregation within lung capillaries, primarily due to endothelial cell injury.
- Fluoride accumulation in the lungs was linked to endothelial damage and subsequent thrombosis.
Impact:
- Identifies lung thrombosis as a critical factor in HF burn fatalities.
- Elucidates the cellular mechanisms of HF toxicity, including endothelial injury and platelet aggregation.
- Provides crucial pathological data for understanding and treating severe HF exposure incidents.
