Summary
Severe burns disrupt lymph circulation, increasing inflammatory factors and endotoxin translocation via the lymphatic system. This leads to local immunosuppression, impacting burn wound healing and patient outcomes.
Area of Science:
- Physiology
- Immunology
- Pathology
Context:
- Severe burns cause significant pathophysiological alterations in the lymphatic system.
- Understanding these changes is crucial for managing burn complications.
Purpose:
- To elucidate the importance of lymph circulation changes post-burn by summarizing experimental findings.
- To investigate the role of the lymphatic system in the inflammatory and immune response to severe burns.
Summary:
- Lymphatic contraction frequency decreases, while lymph flow speed increases during burn shock.
- Elevated levels of inflammatory factors (TNF-alpha, IL-6, IL-8, IL-10, IL-18, HMGB-1) and endotoxins are observed in lymph and lymph nodes, exceeding blood and liver concentrations.
- Lymphatic translocation of endotoxins and bacterial invasion (e.g., Pseudomonas aeruginosa) occur via the lymphatic route.
- A shift towards Th2 immunity and decreased CD4+/CD8+ T cell ratios in lymph nodes indicate local immunosuppression, potentially due to lymphocyte apoptosis.
Impact:
- Highlights the lymphatic system as a critical pathway for inflammatory mediator and pathogen dissemination after burns.
- Suggests the lymphatic system's involvement in the immunosuppression observed in burn patients.
- Provides insights into potential therapeutic targets within the lymphatic system for improving burn patient outcomes.

3.8K
Burn injuries occur when the skin and underlying tissues are damaged due to exposure to heat, electricity, chemicals, radiation, or friction. They can vary in severity, from minor superficial burns to severe deep burns that can be life-threatening.
The damage results in the death of skin cells, which can lead to a massive loss of fluid. Dehydration, electrolyte imbalance, and renal and circulatory failure follow, which can be fatal. Burn patients are treated with intravenous fluids to offset...

01:15Development of the Lymphatic System
1.8K
The development of lymphatic tissues and vessels in embryonic life begins around the fifth week. These structures originate from the mesoderm layer, with lymph sacs emerging from developing veins.
The first lymph sacs to form are the paired jugular lymph sacs located at the junction of the internal jugular and subclavian veins. From these sacs, lymphatic capillary plexuses extend to the thorax, upper limbs, neck, and head, eventually forming lymphatic vessels. Each jugular lymph sac maintains a...

01:16Lymphatic Vessels and Lymph Transport
21.6K
Lymphatic vessels, known as lymphatics, are crucial in transporting lymph from peripheral tissues to our venous system. This process begins with lymph entering through tiny capillaries that branch through tissues. These capillaries have unique features such as larger diameters, thinner walls, and a distinctive one-way valve system formed by overlapping endothelial cells.
This one-way system allows fluids, solutes, and even pathogens to enter but prevents their return to the intercellular...

01:20Overview of the Vascular System
3.3K
The vascular system comprises an extensive network of arteries, capillaries, and veins. The vascular system can be broadly divided into the blood and lymphatic systems. Typically, blood vessels can be categorized into three histological regions: tunica intima, tunica media, and tunica adventitia. The tunica intima consists of a single layer of endothelial cells attached to the basal lamina. Underlying the basal lamina is a connective tissue layer and an elastic lamina that gives stability and...
