“…oxyradical scavenger that may functionally substitute antioxidant enzymes and/or help them to protect cells from oxidative stress (Viarengo et al, 1999). Our results are in agreement with those reported by Viarengo et al (1991) and Regoli (1998) for M. galloprovincialis, in which a general reduction of the antioxidant defence was found during the winter as a probable consequence of a change in the metabolic status of the animals. There is known to be a close functional relationship between the digestive system and gonad development and periods of food abundance (Mackie, 1984).…”

Seasonal variations of trace metals did not appear to influence those of biochemical parameters, which generally showed an opposite trend with higher enzymatic activities in summer when trace metal concentrations were lower. Organisms from Punta Cuevas (control site) showed higher induction of reactive oxygen species production than those from both considered impacted sites, suggesting the possibility of some biochemical adaptation in organisms or a higher modulation of environmental and physiological factors on antioxidant responses than levels of trace metals. This study, which is the first in the area in this matter, showed that seasonal variations of potential biomarkers should be incorporated into interpretation of long-term biomonitoring studies in this marine coastal ecosystem.

“…In liver and kidney of rats MDA concentrations were even lower in older animals (Cand and Verdetti, 1989). Furthermore, seasonal oscillation in MDA levels has been shown for Mytilus gallopro6incialis (Viarengo et al, 1991b). In the mantle musculature of S. officinalis only 10 months old, animals displayed a significant increase in MDA concentration.…”

Activities of the antioxidative enzymes superoxide dismutase (SOD), catalase, glutathione peroxidase (GPX) and glutathione reductase (GR) were measured in the cephalopods Sepia officinalis and Lolliguncula bre6is. Maximal enzyme activities were higher in gill tissue than in the mantle musculature of both species. Activities were generally lower in tissues of L. bre6is than in S. officinalis. Comparison with other ectothermic animals showed both cephalopod species to have a low enzymatic antioxidative status despite their high metabolic rate. Furthermore, changes in antioxidative enzyme activities were measured in the cuttlefish S. officinalis with increasing age. The concentrations of malondialdehyde (MDA) and lipofuscin were determined as indicators of lipid peroxidation. Investigated animals were between 1.5 months and over 12 months old. Changes of antioxidative enzyme activities with age were not uniform. SOD and GPX activities increased with age, while catalase activity declined. In contrast, GR activity remained almost unchanged in all age groups. The low level of antioxidative defense might allow for the significant age-induced rise in MDA levels in gills and mantle musculature and for the increase in lipofuscin levels in mantle and brain tissue. It might thereby contribute to increased oxidative damage and a short life span in these cephalopods.

“…The GSH variations could be related to the changing metabolic status of the organism. Indeed, Viarengo et al (1991) andWilhelm Filho et al (2001) have shown a close link between GSH concentrations and the reproduction cycle in Mytilus sp. and P. perna, respectively.…”

a b s t r a c tAs biomarkers are known to be influenced by biotic and abiotic factors (e.g. gender, temperature), we investigated over a one-year long sampling period, the influence of season and gender on reduced glutathione concentrations and its synthesis in the crustacean amphipod Gammarus roeseli. At the same time, we assessed energy reserves and malondialdehyde levels as toxic biomarker. Results have shown that, in both genders, reduced glutathione concentrations were inversely correlated to water temperature, and higher in females than in males whatever the season. Total lipid and glycogen contents were higher in females than in males, allowing females to have enough energy to assume the reproductive period and maintain high GSH concentrations for detoxification processes. Conversely, females have lower cell damages than males. These differences between genders could induce differential sensitivity in a contamination context, and thus affect the population. Females could resist better than males in contaminated environments, especially in spring when reduced glutathione concentration is the highest.
