	SD	GSSE	HFD	HFD + GSSE
Cu2+ (mg/L)	286 ± 22.72	359.4 ± 33.32	216.5 ± 10.45*	308.2 ± 13.6§
Pb (μg/ L)	1673 ± 266.8	1637 ± 234.4	813.7 ± 152.2*	1575 ± 173§
Tyrosinase activity (U/ mg protein)	0.1383 ± 0.01239	0.1423 ± 0.006984	0.09833 ± 0.007356*	0.1393 ± 0.005783
Glutamine synthetase activity (nmol/min/mg protein)	1.947 ± 0.04842	1.913 ± 0.1618	1.353 ± 0.1179*	1.667 ± 0.1168§

Results are expressed as mean ± SEM (N = 6). p < 0.05 was considered significant: (*) for HFD vs. SD, and (§) for HFD + GSSE vs. HFD. (**) and (§§) for p < 0.01
