Özet

Endotoxemic shock is a severe complication characterized by multiple organ failure, hypotension, and impaired tissue perfusion, all contributing to high morbidity and mortality. Recent studies have highlighted the antiinflammatory and antioxidant properties of tomentosin. This study investigates the protective effects of tomentosin against lipopolysaccharide (LPS)-induced cardiac injury and elucidates its underlying mechanisms. Mice were pre-treated with tomentosin before the LPS administration. Subsequently, cardiac injury markers, oxidative stress parameters, inflammatory mediators, and Nrf-2/NF-kappa B protein expression levels were analysed. The results demonstrated that tomentosin significantly reduced Troponin and CK-MB levels, alleviated oxidative stress, and suppressed inflammatory responses. Furthermore, tomentosin inhibited NF-kappa B activation while enhancing Nrf-2 expression. In conclusion, our findings suggest that tomentosin exerts cardioprotective effects by modulating the Nrf-2/ NF-kappa B pathway, positioning it as a potential therapeutic candidate for preventing LPS-induced cardiac dysfunction.
