Subcellular morphological changes in the rat kidney after phosphorus burn.

J Appelbaum, N Ben-Hur, J Shani

    Pathologia Europaea
    |January 1, 1975

    Summary

    Phosphorus burns cause significant kidney damage at the cellular level, leading to organ dysfunction and high mortality rates in rats. Understanding these subcellular changes is crucial for developing effective treatments for phosphorus burn injuries.

    Area of Science:

    • Toxicology
    • Pathology
    • Renal Medicine

    Background:

    • Phosphorus burns present unique challenges due to elemental phosphorus's toxicity.
    • Subcellular alterations in organs following burns are not fully understood.

    Purpose of the Study:

    • To investigate the subcellular pathological and biochemical changes in rat kidneys after experimental phosphorus burns.
    • To correlate observed cellular damage with physiological dysfunction and mortality.

    Main Methods:

    • Induction of experimental phosphorus burns in male rats.
    • Macroscopic and microscopic examination of organs, focusing on kidneys.
    • Electron microscopy for detailed subcellular analysis.
    • Biochemical assays of serum markers (urea, SGPT, PO-4).

    Main Results:

    • Phosphorus burns induced glomerular ischemia, capillary collapse, mesangial proliferation, and basement membrane thickening.
    • Proximal tubules showed necrotic cells, myelin-like structures in vacuoles, and lumen occlusion by debris.
    • Elevated serum urea, SGPT, and PO-4 levels were detected in burnt rats.

    Conclusions:

    • Phosphorus burns cause severe, multi-faceted kidney damage at the subcellular level.
    • Observed renal pathology and biochemical changes likely contribute to high mortality rates.
    • Findings provide insights into phosphorus burn pathophysiology, aiding treatment strategies.
