In this paper, we examined how the oxidative status (antioxidant system and oxidative damage) of Bombina variegata larvae changed during the metamorphic climax (Gosner stages: 42—beginning, 44—middle and 46—end) and compared the patterns and levels of oxidative stress parameters between individuals developing under constant water availability (control) and those developing under decreasing water availability (desiccation group). Our results revealed that larvae developing under decreasing water availability exhibited increased oxidative damage in the middle and end stages. This was followed by lower levels of glutathione in stages 44 and 46, as well as lower values of catalase, glutathione peroxidase, glutathione S-transferase and sulfhydryl groups in stage 46 (all in relation to control animals). Comparison between stages 42, 44 and 46 within treatments showed that individuals in the last stage demonstrated the highest intensities of lipid oxidative damage in both the control and desiccation groups. As for the parameters of the antioxidant system, control individuals displayed greater variety in response to changes induced by metamorphic climax than individuals exposed to desiccation treatment. The overall decrease in water availability during development led to increased oxidative stress and modifications in the pattern of AOS response to changes induced by metamorphic climax in larvae of B. variegata.

In this research, to determine toxicity of mercury (Hg) and whether selenium (Se) has any role in protection of this toxicity, it was investigated the alterations in oxidative stress parameters in tissues of Oreochromis niloticus. For this purpose, fish were exposed to 0.01 and 0.05 ppm Hg and 0.01 ppm Hg+0.01 ppm Se and 0.05 ppm Hg+0.05 ppm Se for 4 and 21 days and activities of superoxide dismutase (SOD) and catalase (CAT) and levels of malondialdehyde (MDA) in gill and liver were determined. It was observed significant changes in all analyzed parameters due to tissue, medium concentration and exposure period in the exposure of mercury alone and Hg+Se mixtures. In Hg alone, and in combination with Se especially in their higher medium concentrations, activities of SOD and CAT in the gill and liver significantly increased at 4 days (P˂0.05), while they significantly decreased at 21 days (P˂0.05). In the exposure of Hg and Hg+Se and in the both tissues, it not determined significant alteration in the MDA levels at 4 days (P˃0.05), while they elevated in their higher concentrations at 21 days (P˂0.05). In conclusion, it was determined the increases or decreases in activities of SOD and CAT and levels of MDA in O. niloticus were higher in the Hg alone than Hg+Se mixtures and selenium has a protective effect on oxidative toxicity of mercury.
