Effects of K2 and K6 on serum biochemical parameters in the rat model of HF/HF-induced NAFLD. (a) Serum TG, (b) serum TC, (c) serum HDL, (d) fasting serum glucose, (e) leptin, (f) adiponectin, (g) superoxide dismutase (SOD), (h) GPx, and (i) CAT levels. NC, normal diet control; HC, HF/HF diet control; PC, HF/HF diet with silymarin; K2, HF/HF diet with ATG-K2; K6, HF/HF diet with ATG-K6; TG, triglycerides; TC, total cholesterol; HDL, high-density lipoprotein; SOD, superoxide dismutase; GPx, glutathione peroxidase; CAT, catalase. The data are presented as mean ± SD. Means with different letters (a, b, c, and d) are significantly different, p < 0.05, whereas those with similar letters are not different. The groups were compared using one-way ANOVA followed by Duncan’s multiple range tests.
