[Changes in the lipid peroxidation activity and intensity of tissue respiration during healing of aseptic and infected wounds in animal experiments].
The variance of lipid peroxidation (LPO) was studied by the concentrations of malonic dialdehyde (MDA) in the tissue of wound bed and blood serum on the model of surface musculocutaneous aseptic and infected wounds simulated in 250 rats. The speed of oxygen consumption by isolated wound tissue was determined simultaneously. It was stated that the time course of MDA concentration in wounds and sera as well as tissue respiration in animals with infected wounds differed from those in animals with aseptic wounds. In a whole, MDA levels were found to be higher in cases with infected wounds and of changeable character. The latter animals demonstrated less intensive respiration of granulation tissue. Correlation between the variance of tissue respiration and MDA levels was established as was that of LPO and respiration with the phases of wound process. The findings could be used for the development of pathogenetic therapy and evaluation of its efficacy.
