Ascorbic acid content of different tissues of fish following 21-days continuous exposure to nonlethal dose of endosulfan (1/10 dose of LC50) against unexposed control and fed with diets containing lecithin, betaine, and choline during experimental period. Mean values in the same set (one-way ANOVA) with different superscript letters (a, b, c, d) differ significantly. * P < 0.05, **P < 0.01—comparison of unexposed vs. corresponding endosulfan-exposed group.A
P < 0.05 and B
P < 0.01—indicates significant differences between endosulfan-exposed and methyl donor-fed and unexposed control fish. Data expressed as mean ± SE, N = 3
