Abstract
We studied the effect of bleomycin (1 mg/kg) in 1-day-old rat pups (single intraperitoneal injection) and 4-day-old pups (3 injections on postnatal days 1, 2, and 3). The formation of hyaline membranes against the background of oxidative stress was documented in all bleomycin-treated rats. Repeated injection of bleomycin (4-day-old pups) led to more pronounced destructive alterations in the lungs characterized by the formation of microcysts and atelectases as well as hypertrophy of the interstitial connective tissue. These alterations persisted in 14-day-old rats. Administration of bleomycin during the neonatal period can be a promising approach to simulation of hyaline membrane disease (respiratory distress syndrome).
