[The free-radical involvement of the salivary gland in stress]. / Svobodnoradikal'noe porazhenie sliunnoi zhelezy pri stresse.

It has been demonstrated in rat experiments that acute emotional painful stress enhanced free-radical lipid oxidation in salivary gland tissues and reduced the activities of antioxidant enzymes in it. Similar processes take place in the blood. Antiaggregation activity increases in the tissues of salivary gland, this being an essential adaptation factor in stress, preventing microcirculatory disorders in the tissues.

During a 5-year follow-up of rescue party members exposed to radioactive effects of the Chernobyl accident no material changes were observed versus healthy donors in the content of calcium, cholesterol, atherogenic lipoproteins, dienic conjugates, insulin, thyroxin, triiodothyronine, thyroglobulin, IgA, IgG and fibrinogen. Inhibition of peroxidation and emergence of hypocoagulation are attributed to a reduced respiratory splash of the neutrophils. Concentrations of hydrocortisone, testosterone, IgM rose, while the activity of some antioxidant enzymes remained stable.
