Abstract:
Objective(s): Obesity is a metabolic syndrome that leads to many chronic diseases worldwide. In this study, we investigate the antihyperlipidemic activities of chitosan nanoparticles (CH NPs) on silymarin (SIL) as a carrier in the drug delivery system that can improve some biochemical parameters and hormones in the model of hyperlipidemic rats receiving a high-fat diet (HFD). Materials and Methods: Physicochemical characterization of silymarin-loaded chitosannanoparticles (CH-SIL NPs) was done by Fourier-transform infrared (FTIR) spectroscopy, dynamic light scattering (DLS), and drug loading efficiency (LE). Diet-induced hyperlipidemic rats were treated with SIL (۱۵ mg/kg/day) and CH-SIL NPs(۱۵ mg/kg/day) for twelve weeks orally daily. The body weight loss (BW), food consumption, serum total cholesterol (TC), triglycerides (TG), high-density lipoprotein (HDL), levels of fasting blood glucose (FBG) in serum, serum insulin, cortisol, testosterone, and brain neuropeptide Y (NPY), Y۱ and Y۵ receptor mRNA expression were analyzed. Results: A significant reduction in BW and food consumption from ۴۱۷ ± ۱۶ g and ۳۳ ± ۱.۰۳ in group HFD to ۳۳۸ ± ۱۰ g and ۱۷.۳۳ ± ۱.۰۲ in group CHS+HFD was observed, respectively. This data revealed that CH-SIL NPs improved hyperlipidemia, hyperinsulinemia, and hyperglycemia, reduced serum cortisol, and down-regulated NPY and Y۱R with a significant increase in HDL and testosterone hormones compared to the control group. Conclusion: The developed Sil-loaded CH NPs were good agents for improving efficacy. It is the first report of the proposed weight loss mechanism of SIL CH NPs, thereby providing information about the anti-hyperlipidemic and antihyperglycemic effects of silymarin-loaded chitosan nanoparticles, a natural food with proper effects against metabolic disorders in case of hyperlipidemia that may lead to obesity and up-regulation of brain NPY.
