Ethyl Pyruvate Injection Enhances the Ischaemic Zone Viability in Burn Wounds in Rats

Area of Science:

• Biomedical Science
• Wound Healing Research
• Pharmacology

Background:

• Burn injuries present significant clinical challenges due to oxidative stress, inflammation, and tissue necrosis, impairing healing.
• Ethyl pyruvate (EP) exhibits anti-inflammatory, antioxidant, anti-apoptotic, and anti-fibrotic properties, indicating therapeutic potential for burns.

Purpose of the Study:

• To evaluate the efficacy of ethyl pyruvate (EP) in promoting burn wound healing.
• To assess EP's ability to prevent progressive tissue necrosis in burn injuries.

Main Methods:

• 30 male Wistar rats with thermal injuries were divided into three groups: EP treatment (multiple doses), EP treatment (single dose), and saline control.
• Assessments included macroscopic, histopathological, immunohistochemical, and biochemical analyses (MDA, TAC).
• Evaluations were conducted on days 3 and 21 post-injury.

Main Results:

• Ethyl pyruvate (EP) administration effectively reduced and controlled oxidative stress and inflammation.
• EP treatment led to preservation of the stasis zone and accelerated healing in the coagulation area.
• Biochemical markers indicated a reduction in oxidative stress and an increase in antioxidant capacity.

Conclusions:

• Ethyl pyruvate (EP) injection halts progressive tissue necrosis in the stasis zone of burn wounds.
• EP significantly promotes burn wound healing, primarily attributed to its anti-inflammatory and antioxidant effects.
• EP is a promising therapeutic agent for managing burn injuries.
