Abstract

The antioxidant glutathione system (AGS) and lipid peroxidation (LP) level in tissues of the Black Sea cockle Cerastoderma glaucum (Bruguière, 1789) have been investigated and compared with those of other Black Sea bivalve mollusks with high resistance to oxidative stress (OS), namely, mussel Mytilus galloprovincialis (Lamarck, 1819) and anadara Anadara kagoshimensis (Tokunaga, 1906). The activity of glutathione peroxidase (GP) and glutathione reductase (GR) and the level of reduced glutathione (GSH) and LP products are measured in the hepatopancreas, gills, and foot of the mollusks. The parameters of AGS in C. glaucum are found to have tissue specificity. The hepatopancreas has the highest GP activity, 1.7–4.2 times higher than in the gills and foot of the mollusk. The gills have the lowest GSH level (by a factor of 2.1–2.3 times lower) and the highest GR activity (3.1–5.8 times higher) when compared to other tissues. In the cockle foot, the level of GSH is close to that in hepatopancreas and the activity of GP and GR is by a factor of 1.7–4.2 lower than in other tissues. In all studied tissues of C. glaucum, the LP level is significantly lower, i.e., by a factor of 3.2–16.3, when compared with that in mussel and anadara.

黑海双壳软体动物青皮褐皮病（Cardiidae）组织中抗氧化型谷胱甘肽系统的特定特征

摘要

研究了黑海蛤C青皮的皮肤中的抗氧化剂谷胱甘肽系统（AGS）和脂质过氧化（LP）水平（Bruguière，1789年），并将其与对氧化应激（OS）具有高抵抗力的其他黑海双壳贝类软体动物进行了比较。 ，即贻贝Mytilus galloprovincialis（Lamarck，1819）和Anadara Anadara kagoshimensis（Tokunaga，1906）。在软体动物的肝胰腺、,和足中测量谷胱甘肽过氧化物酶（GP）和谷胱甘肽还原酶（GR）的活性以及还原型谷胱甘肽（GSH）和LP产物的水平。青光眼中AGS的参数被发现具有组织特异性。肝胰腺的GP活性最高，比软体动物的the和足高1.7-4.2倍。与其他组织相比，具有最低的GSH水平（低2.1-2.3倍）和最高的GR活性（高3.1-5.8倍）。在鸟蛤脚中，GSH的水平与肝胰腺中的GSH接近，GP和GR的活性比其他组织低1.7-4.2倍。在所有研究的组织中C.灰绿，当与在贻贝和anadara相比，LP水平显著下，即，通过的3.2-16.3倍。
