Abstract

Tyloxapol is a nonionic surfactant oligomer inductor of dyslipidemia, which in turn is a risk factor for liver damage. Selenium-based compounds have emerged as promising therapeutic candidates for treating different experimental disorders. This study investigated the effects of p-chloro-diphenyl diselenide (p-ClPhSe)2 on toxicity induced by Tyloxapol in rats. Plasma lipid profile, hepatic functionality and oxidative stress parameters were evaluated in adult male Wistar rats treated with (p-ClPhSe)2 (10 mg/kg; oral administration by gavage) for seven days and exposed to a single Tyloxapol injection (400 mg/kg; intraperitoneal route) 30 min after the last (p-ClPhSe)2 treatment. Tyloxapol exposure increased the plasma levels of total cholesterol, triacylglycerol, non-HDL-cholesterol and the calculated cardiac risk index (CRI). The plasma activities of alanine and aspartate aminotransferase (ALT and AST, liver function markers) were increased in rats exposed to Tyloxapol, which demonstrates a hepatic lipotoxicity. In the liver, reactive oxygen species (ROS) content was enhanced and the non-protein sulfhydryl (NPSH) levels were decreased by Tyloxapol. The data revealed that repeated treatment with (p-ClPhSe)2 reduced plasma lipid alterations and hepatotoxicity induced by Tyloxapol. Although (p-ClPhSe)2 did not reduce ROS levels increased by Tyloxapol, it increased NPSH content in the liver. Pearson’s correlation coefficient revealed a positive relationship between the levels of hepatic NPSH and plasma HDL. HDL is known by eliciting antioxidant activity; therefore, the improvement in HDL function could be suggested as a therapeutic target. In conclusion, the results demonstrate the protective effects of (p-ClPhSe)2 on the hepatic lipotoxicity induced by Tyloxapol in rats.
