THE ROLE OF LIPID PEROXIDATION AND ANTIOXIDANT SYSTEM IN THE PATOGENESIS OF THE EARLY PERIOD OF STOMACH ULCER IN EXPERIMENTAL PNEUMONIA

Experimental research of lungs of guinea pigs in the early period of ulcer on a background of pneumonia demonstrated growth of prooxidant system indices, including diene conjugates and malondialdehyde, and changes in enzyme antioxidant system (superoxide dismutase, catalase, glutathione peroxidase, glutathione reductase), which indicates the development of oxidative stress.
