Abstract
Bleomycin-induced lung damage was assessed using both a functional end-point and mortality. The extent of lung damage was found to depend on the schedule, mode of administration and dose of the drug. Greater damage occurred following twiceweekly administration than when the same dose was given as a single injection. Intravenous administration resulted in greater damage than intraperitoneal administration. When bleomycin was given with thoracic irradiation lung damage occurred earlier and at lower radiation doses than with radiation alone. Similar responses were obtained whether bleomycin was given four weeks before, with or four weeks after irradiation. Thus although there was enhanced damage from the combined treatment, there was no evidence of a timedependent interaction.
