- fear and anxiety are considered in animals (especially in domestic animals and especially in pets - such as the dog (Canis lupus familiaris) or the cat (Felis silvestris catus). ) and new pets (NAC) - as major emotional disorders, because dogs experiencing these conditions may exhibit behavioral disturbances (also known as behavioral disturbances), that is, unwanted behaviors that may be affect dog-human relationships and unfortunately lead to reactions ranging from abandonment to euthanasia (Bamberger and Houpt 2006, Casey 2002).
- behavioral disturbances also known as behavioral disturbances

- SOD Superoxide dismutase
- SOD is a ubiquitous enzyme (ie present in almost all aerobic organisms), different isoforms of this metalloprotein having been subsequently demonstrated, each characterized by
- a metal ion located at its active site (Cu, Zn, Fe or Mn metal cofactors).
- Fe SOD iron form
- the different isoforms of SOD are determined by their sensitivity:
- Fe SOD is inhibited by H2O2 and low concentrations of SDS.
- the radical O 2 can hardly cross the plasma membranes, therefore it must be detoxified in the same compartment where it was formed. This phenomenon explains the existence of different cytosolic, mitochondrial and extracellular superoxide dismutase isoforms.
- Cytosolic CuZn SOD is a soluble enzyme, generally very stable, mainly present in the cytosol of eukaryotic cells (exists in certain bacteria), but also in the chloroplasts of plant cells.
- Homodimeric intracellular protein its two subunits each contain a Cu 2+ ion and a Zn 2+ ion and their molecular weight varies from 16 to 19 kDa.
- the spatial organization of the electrostatic field at the surface of the Cu / Zn superoxide dismutase reveals a positively charged region, creating a chasm that leads the superoxide radicals to the copper ion to cause an effective collision.
- the extracellular form is a glycosylated tetrameric Cu / Zn superoxide dismutase. It is present in mammals, some plants, as well as some prokaryotes. Within the bacteria this enzyme is periplasmic, and is not released into the medium extracellular only following an osmotic shock. Its presence is necessary to protect the cell against the many extracellular 02 sources.
- Mn SOD is a homodimeric mitochondrial enzyme of 40 to 46 kDa in eukaryotes, in tetrameric form of 110 to 140 kDa in prokaryotes.
- Fe SOD non-existent in animal tissues, as indicated above, has important homologies, amino acid sequences and structure, with Mn SOD. Homodimeric, each of its subunits contains an iron atom and has a molecular weight of 23 kDa, it can also be found in tetrameric form in mammals.
- free radicals such as reactive oxygen species (ORS).
- ORS reactive oxygen species
- the increase in the level of free radicals causes numerous non-reversible damage to the cells of the body, such as peroxidation of membrane lipids, mitochondrial degradations, protein oxidation and alterations of the DNA.
- free radicals can induce mutagenic effects or the stop of DNA replications (base alteration, DNA-protein bridging, strand breaks, cross-links).
- the OH radicals are the main cause of the damage. They come from the Fenton reaction, in the presence of ferrous iron chelated to certain amino acids or phosphate groups of DNA. Very reactive, they react immediately on their formation sites, that is to say the nucleotide part with which they are directly in contact. These active forms of oxygen are also responsible for enzymatic inactivations, fragmentation of macromolecules, formation of dimers or protein aggregates in cytoplasmic membranes.
- oxidative stress is the essential initial cause of many pathologies such as cancers, pulmonary edema, acute pulmonary distress syndrome, amyotrophic lateral sclerosis, pro-inflammatory and cardiovascular diseases, neurological disorders, fibrosis, diabetes, cellular aging, Alzheimer's disease, rheumatism or accelerated aging.
- Oxidative stress is also a factor that potentiates the genesis of multifactorial diseases such as diabetes, Alzheimer's disease, rheumatism and cardiovascular diseases.
- the enzymatic activity of SOD makes it possible to reduce the quantity of superoxide anions present in the body and, consequently, to prevent and / or inhibit the oxidative damage that can be caused by oxidizing molecules derived from the superoxide anion.
- oxidizing molecules derived from the superoxide anion such as the hydroxyl radical or peroxynitrite.
