The possibility of boosting antifibrotic activity of testicular hyaluronidase immobilized on polyethylene oxide with spiperone was studied on the bleomycin models of a single (partially reversible pneumofibrosis) and repeated (irreversible pneumofi brosis) injuries to the alveolar epithelium in C57Bl/6 mice. The antifibrotic effect was more pronounced after successive treatment with immobilized hyaluronidase and spiperone than after individual treatment with each of the compounds: no collagen deposition in the parenchyma of bleomycin-damaged lungs was found. The decrease in inflammatory cell (lymphocytes, macrophages, neutrophils, plasma cells) infi ltration of the alveoli and alveolar tracts interstitium in mice treated by immobilized hyaluronidase and spiperone did not differ from the anti-inflammatory effect of spiperone monotherapy.
