Abstract
Curcumin is a natural phenolic compound extracted from the herbCurcuma longaL. rhizome and has received much attention on account of its biological properties. However, its poor solubility and low bioavailability limit its use. The purpose of this study was to synthesize curcumin-loaded nanoliposomes (Cur-NLs) to improve their bioavailability and evaluate the hepatoprotective effect of Cur-NLs against tetrachloromethane- (CCl4-) induced acute liver injury in mice. We prepared Cur-NLs by thin film dispersion method, and the characterizations of Cur-NLs were measured by transmission microscope, laser particle size analyzer, infrared spectrometer, and X-ray diffraction. After 14 days pretreatment of Cur-NLs, free curcumin, silybin, or PBS, the models of acute liver injury were established by CCl4intraperitoneal injection in mice. The organ index, biochemical liver function parameters, histopathology, and antioxidant enzyme activities of liver tissues were measured further to evaluate the protective effects of Cur-NLs on liver injury. Compared with the CCl4model control group, pretreatment of Cur-NLs effectively reduced the serum levels of ALT, AST, and ALP and attenuated the hepatic necrosis induced by CCl4intoxication. Furthermore, Cur-NL pretreatment remarkably exhibited decreased MDA level and increased SOD, GPx, and CAT activities compared to CCl4model control group. Compared with the free curcumin group, the Cur-NLs also showed a better hepatoprotective effect. These observations imply that Cur-NLs act as a promising hepatoprotective agent in reducing liver oxidative stress produced by different stress factors.
