Gostyukhina O. The particular features of the tissue antioxidant status of bivalve Mytilus galloprovincialis Lam. under the oxidative stress conditions

Dissertation is devoted research of features of antioxidant (AO) status of different functional specialization tissues of bivalve Mytilus galloprovincialis Lam. in the conditions of oxidizing stress of different nature. It has been found that the antioxidant (AO) system organization of the mussels possesses pronounced tissue specificity. It has been shown that low content of carotenoids (depigmented mussels) is accompanied by lipid peroxidation (LP) intensification and decline activity of AO system. The adaptation reactions of mussels at spawning were expressed in the increasing in LP level and activation of all links of AO defense. It has been found that artificial stress affects mussel's gills. The adaptation reactions of this tissue are expressed in activation of AO system with high and low affinity to substrate and in the LP level increasing. The black morph mussels have higher sensitivity to oxidative stress, in comparison with those of brown morph. The AO complex of gills complies with ecodiagnostics purposes to а greater extent.
