Effect of LU on the heart lipid peroxidation products and antioxidant enzymes.

Parameters	Control	LU	ISO	LU + ISO
MDA (nmol/mg protein)	0.59 ± 0.06	0.61 ± 0.08	1.35 ± 0.15a#	0.78 ± 0.08b#
SOD (U/mg protein)	5.05 ± 0.50	5.03 ± 0.50	3.31 ± 0.33a#	4.52 ± 0.47b#
CAT (U/mg protein)	14.84 ± 1.40	14.90 ± 1.60	10.80 ± 1.10a#	12.22 ± 1.20b*

Values are presented as the mean ± standard error of mean (SEM). The probability value (p-value; ^#p < 0.01, *p < 0.05): where ‘a’ indicates the significant difference between ISO group and Control group, while ‘b’ indicates the significant difference between LU + ISO group and ISO induced groups. LU: lutein; ISO: isoproterenol; NS: non-significant.
