Modification of X-ray-induced lung pathology after intratracheal administration of phosphatidylcholine-cholesterol liposomes
Abstract
The possibility of correction of X -ray-induced rat lungs pathology was investigated after a single intratracheal administration of phosphatidylcholine-cholesterol liposomes in dose 40 mg per kg of body weight. The rig h t rat lung was irradiated in dose 12 or 14 Gr once. The lung tissue underwent histological and electron -microscopic examination using morphometric methods in 7 and 13 weeks after irradiation. The decrease of intensity and extension of radial alveolitis was revealed. Ultrastructure alteration of some alveolocapillary barrier elements in treated animals was lower than in untreated ones. Intratracheal liposome administration can be used in complex therapy for the reduction of the severity of radio-induced lung injury.
