DMG-gold restored serum metabolic parameters and hepatic markers in serum of HFD animals. Metabolic parameters, such as triglycerides (A) and cholesterol (B), alanine aminotransferase (ALT) (C), aspartate aminotransferase (AST) (D), adiponectin (E), leptin (F), glucose and insulin (G) and insulin resistance-homoeostatic model assessment (IR-HOMA) index (H), were measured in serum. Data are presented as means ± SEM from n = 7 animals/group. CTR: control, HFD: high-fat diet, DMG: DMG-gold. Different superscripted letters on the histograms (a,b,c) indicate significantly different average values, p < 0.05.
