    Area of Science:

    • Biochemistry
    • Hematology
    • Toxicology

    Background:

    • Hematomas represent localized bleeding under the skin.
    • Iron is a critical component of hemoglobin and cellular processes.
    • Understanding iron dynamics in hematomas is important for clinical and research applications.

    Purpose of the Study:

    • To quantify extractable and total iron content in rat subcutaneous hematomas over time.
    • To determine the proportion of extractable iron relative to total iron as hematomas age.
    • To assess the impact of autolysis on iron measurements in fresh hematomas.

    Main Methods:

    • Experimental subcutaneous hematomas were created in rats.
    • Iron concentrations were measured using acid digestion (total iron) and incubation with HCl followed by protein precipitation (extractable iron).

  • Control tissue samples were analyzed for baseline iron levels.

    • Main Results:

    • Extractable iron levels in hematomas significantly exceeded control values starting from 2 days post-formation.
    • Extractable iron increased substantially, reaching approximately 5x, 15x, and 20x control levels at 3, 7, and 14 days, respectively.
    • The ratio of extractable to total iron rose from ~1% at 1 day to ~65% by 14 days.

    Conclusions:

    • Iron becomes increasingly extractable from subcutaneous hematomas in rats as they age.
    • The proportion of extractable iron increases significantly with hematoma maturation.
    • Autolysis had a minimal, statistically insignificant impact on extractable iron measurements in short-term samples.
