Gender Peculiarities of Protein and Lipid Peroxidation of the Oral Liquid Under the Conditions of Preclinical Iodine and Iron Deficiency
Abstract
The prevalence of somatic pathology in children increases significantly with each passing year, which is associated with socio-economic, environmental conditions, the complex interaction of exogenous and endogenous factors. This problem may be related to micronutrient imbalances, among which iodine deficiency and sideropenia are quite common.
Objective. The aim of the study is to learn the peculiarities of peroxidation of proteins and lipids, the system of antioxidant defence of oral fluid in conditions of preclinical iodine and iron deficiency.
Materials and Methods. The study included 115 children aged 6-18 years. The level of peroxidation of proteins was characterized by the content of oxidative modification of protein products (aldehyde derivatives of the main nature) in the oral fluid. Peroxidation of lipids of oral fluid was assessed by the accumulation of diene conjugates (DCs) of polyunsaturated fatty acids and products responding to thiobarbituric acid (TBA-RP).
Results. It has been determined that in case of iodine and iron deficiencies, their combination causes significant activation of protein and lipid peroxidation processes in the oral fluid of children, accompanied by an imbalance of the prooxidant-antioxidant system of the oral cavity.
Conclusion. Such changes can be predictors of the development of dental pathology
