Abstract
Context: The heart is one of the target organs susceptible to attack by sepsis, and protection of the cardiac function in sepsis or alleviation dysfunction caused by sepsis appears a serious and urgent problem.
Objective: This study was designed to explore the effect of curcumin on myocardial injury induced by sepsis and to explore the therapeutic effect of curcumin in managing sepsis induced cardiac dysfunction.
Methods: Cecal ligation and puncture surgery were used to establish the sepsis model. Curcumin was administered by peritoneal injection (200 mg/kg/d, 3 days). The effects of curcumin on the cardiac functions [Ejection Fraction (EF), Fractional Shortening (FS), Cardiac Output (CO), Heart Rate (HR)], body temperature, cTn I and superoxide dismutase levels, malondialdehyde content (an index of lipid peroxidation), and myocardial histopathological and ultrastructural studies were carried out.
Results: We demonstrated that treatment of rats with curcumin significantly decreased elevated levels of cTn I and MDA (p < 0.05) in plasma, and increase the levels of SOD (p < 0.05) after CLP. Moreover, curcumin markedly enhanced the myocardial contractility by increasing the decreased EF and FS in rats with sepsis induced by CLP (p < 0.05). In addition, curcumin could alleviate the myocardial inflammation and structure damage of myocardial cells in sepsis induced by CLP.
Conclusion: In conclusion, the results from the present study demonstrate that curcumin has the protective effects on cardiac function in rats with sepsis and curcumin could be considered as an effective and safe therapeutic agent for the management of sepsis induced cardiac dysfunction.
