PROCESSES OF LIPID PEROXIDATION AND ANTIOXIDANT PROTECTION IN ACUTE ODONOGIC OSTEOMYELITIS IN CHILDREN

Abstract

The paper presented summarizes the results on the parameters of free radical lipid oxidation and antioxidant protection factors in 24 children aged from 3 to 15 years with acute odontogenic mandible osteomyelitis. In addition to standard clinical examination, peripheral blood and unstimulated oral fluid fractions were collected from all patients for 10 min at hospital admission and discharge. The samples were used to determine the components of lipid peroxidation: diene conjugates; malondialdehyde, its initial level, in 1.5 hours of incubation and its growth; antioxidant protection factors as superoxide dismutase, and catalase. It has been found out at the time of hospitalization, clinical examination showed a significant deterioration of the general condition, which was accompanied by widespread infiltrative changes and collateral oedema in the projection of the involved region of the mandible. In 12 people (50%) osteomyelitis spread from temporary molars. In other cases, permanent first and second molars were regarded as the causes. The patients demonstrated the activation of lipid peroxidation processes and reduction of antioxidant protection factors found out in peripheral blood and unstimulated oral fluid fraction. Repeated studies over the clinical recovery following the treatment conducted in accordance with the protocol of medical care enables to estimate the absence of infiltrative changes, but despite the elimination of acute inflammation, not all the studied parameters reached the level of control values. This makes it necessary to address the issue on making corrections towards the complex of therapeutic measures by including antioxidants that seems to be quiet promising and requires further in-depth investigation.
