title: Myoinositol decreases N-nitroso-N-methylurethane induced lung surfactant deficiency.
abstract: Administration of 7.5 mg/kg body wt. of N-nitroso-N-methylurethane subcutaneously to rabbits decreased disaturated phosphatidylcholine, phosphatidylglycerol, and increased the minimum surface tension of alveolar lavage return. As compared to rabbits treated with N-nitroso-N-methylurethane alone, myoinositol supplementation (3-7 g/kg per day) of N-nitroso-N-methylurethane treated animals largely prevented both the decrease in disaturated phosphatidylcholine, and the increase in minimum surface tension. Myoinositol may be an important nutrient following damage of alveolar epithelium.
