Steroid Therapy for Pneumonitis Induced in Rabbits by Aspiration of Foodstuff

Abstract
The instillation of gastric contents, 0.5 ml/kg (pH 4.3), containing small food particles into the left diaphragmatic lobe of the lungs of 49 rabbits caused severe aspiration pneumonitis. Administration of methylprednisolone (30 mg/kg, i.m.) every 8 h for 3 days to 26 of the 49 rabbits did not alter the rate of roentgenographic resolution of the pneumonitis. Corticosteroids decreased the fibroblastic response of the lung to the aspirate, but also interfered with healing of granulomatous lesions.
