The Mucoproteins of the Snails, Helix Aspersa and Helix Pomatia
The problem of the structure of complex proteins containing carbohydrates in their molecule is still a subject of discussion. The fundamental questions which have been debated during the last decades and which have been the subject of many controversies are concerned with the nature of the carbohydrate group present in the molecule of these substances. Since the discovery of mucoproteins or muc...
متن کاملSeasonal modulation of free radical metabolism in estivating land snails Helix aspersa.
We investigated the regulation of free radical metabolism in Helix aspersa snails during a cycle of 20-day estivation and 24-h arousal in summer in comparison with estivation/arousal in winter-snails. In winter-snails (J. Exp. Biol. 206, 675-685, 2003), we had already observed an increase in the selenium-dependent glutathione-peroxidase (Se-GPX) activity in foot muscle and hepatopancreas and in...
متن کاملPesticides induced oxidative stress in mammalian systems
Contents For over last two decades, the toxicological research has focused on pesticide-induced oxidative stress (OS) as a possible mechanism of toxicity. In fact OS is an outcome of a multistep process spanning from perturbations in the balance between the levels of oxidants / prooxidants and antioxidants (both enzymatic and non-enzymatic) to tissue damage leading to onset of several disease s...
متن کاملOrgan Profiles of the Antioxidant Defence System and Accumulation of Metals in Helix aspersa Snails
This paper studied the association between metals accumulation in selected tissues and the shell and antioxidant defence system in Helix aspersa snails. Accumulation of Zn, Fe, Pb, Cd, and Mg was organ-specific and was the highest in the hepatopancreas. Hepatopancreatic catalase and glutathione peroxidase activities were the highest, whereas the highest glutathione reductase activity was record...
متن کاملEffects and uptake of polycyclic aromatic compounds in snails (Helix aspersa).
The International Standardization Organization recently launched a soil toxicity test with snails (Helix aspersa). We assessed the sensitivity of this test for seven polycyclic aromatic compounds. Control animals had 100% survival and low variability for growth measurements. Maximum exposure concentrations of 2800 mg/kg (4000 mg/kg for acridine) had no effect on survival. Similarly, growth (bio...
