Fig. 4From: Lutein Dietary Supplementation Attenuates Streptozotocin-induced testicular damage and oxidative stress in diabetic ratsEffect of lutein on testicular activities of (a) SOD and (b) CAT of diabetic rats. Note the up regulating of both enzymes on the lutein dose dependent groups comparing to D group. Data were expressed as Mean ± SEM. and analyzed using one-way ANOVA followed by Student-Newman-Keuls multiple comparisons test (n = 6). Difference between groups was considered statistically significant when (*) P ≤ 0.05 and (**) P ≤ 0.01. (a)D group was compared with ND group; (b)lutein treated groups were compared with D groupBack to article page
