    ABSTRACT

    Background: The fruits of Aronia melanocarpa (Michx.) Elliot is extremely rich in biologically active polyphenols. Objective: We studied the protective effect of A. melanocarpa fruit juice (AMFJ) in a model of amiodarone (AD)-induced pneumotoxicity in rats. Materials and Methods: AD was instilled intratracheally on days 0 and 2 (6.25 mg/kg). AMFJ (5 mL/kg and 10 mL/kg) was given orally from day 1 to days 2, 4, 9, and 10 to rats, which were sacrifi ced respectively on days 3, 5, 10, and 28 when biochemical, cytological, and immunological assays were performed. Results: AMFJ antagonized AD-induced increase of the lung weight coeffi cient. In bronchoalveolar lavage fl uid, AD increased signifi cantly the protein content, total cell count, polymorphonuclear cells, lymphocytes and the activity of lactate dehydrogenase, acid phosphatase and alkaline phosphatase on days 3 and 5. In AMFJ-treated rats these indices of direct toxic damage did not differ signifi cantly from the control values. In lung tissue, AD induced oxidative stress measured by malondialdehyde content and fi brosis assessed by the hydroxyproline level. AMFJ prevented these effects of AD. In rat serum, AD caused a signifi cant elevation of interleukin IL-6 on days 3 and 5, and a decrease of IL-10 on day 3. In AMFJ-treated rats, these indices of infl ammation had values that did not differ signifi cantly from the control ones. Conclusion: AMFJ could have a protective effect against AD-induced pulmonary toxicity as evidenced by the reduced signs of AD-induced direct toxic damage, oxidative stress, infl ammation, and fi brosis.
