OBJECTIVE Comparison of the levels of lipid peroxidation (LPO) products in condensate of the exhaled air (CEA) and in the biopsy samples from the inflammation focus. METHODS Extraction spectrophotometry was used to measure LPO products in CEA and biopsies from 30 males aged 30-60 years suffering from chronic bronchitis and 30 healthy controls of the same age. RESULTS There was activation of local accumulation of isopropanol-soluble LPO products in the bronchopulmonary system accompanied by lowered content of lipoperoxides and high antioxidant activity in CEA. CONCLUSIONS Chronic bronchitis is characterized by multidirectional shifts in LPO in the inflammation focus and CEA.

D002908 Chronic Disease Diseases which have one or more of the following characteristics: they are permanent, leave residual disability, are caused by nonreversible pathological alteration, require special training of the patient for rehabilitation, or may be expected to require a long period of supervision, observation, or care (Dictionary of Health Services Management, 2d ed).

D005609 Free Radicals Highly reactive molecules with an unsatisfied electron valence pair. Free radicals are produced in both normal and pathological processes. Free radicals include reactive oxygen and nitrogen species (RONS). They are proven or suspected agents of tissue damage in a wide variety of circumstances including radiation, damage from environment chemicals, and aging. Natural and pharmacological prevention of free radical damage is being actively investigated. Free Radical
