[An experimental study on systemic inflammatory response syndrome induced by subeschar tissue fluid]
1Burn Unit, Nanfang Hospital, First Military Medical University, Guang Zhou, 510515, Guang Dong Provine, P.R. China.
Summary
Subeschar tissue fluid (STF) infusion in rats increased heart and respiratory rates, causing organ damage. STF activates macrophages, releasing inflammatory mediators like TNF-alpha and IL-1, potentially leading to SIRS and MODS.
Area of Science:
- Biomedical Science
- Physiology
- Immunology
Context:
- Subeschar tissue fluid (STF) is implicated in burn wound pathophysiology.
- Understanding STF's systemic effects is crucial for managing severe injuries.
Purpose:
- To investigate the physiological and cellular effects of STF.
- To explore the relationship between STF and inflammatory mediators.
Summary:
- Infusion of STF into rats elevated heart and respiratory rates, increased leukocyte counts, and caused multi-organ damage (lungs, liver, kidneys).
- In vitro studies demonstrated that STF activates peritoneal macrophages, stimulating the release of tumor necrosis factor-alpha (TNF-α) and interleukin-1 (IL-1).
Impact:
- STF may play a significant role in the development of Systemic Inflammatory Response Syndrome (SIRS).
- This research suggests STF could be a key factor in the progression to Multiple Organ Dysfunction Syndrome (MODS).
