Treatment of neonatal rats with repeated doses of monosodium-L-glutamate resulted in changes of morphology and function of alveolar macrophages recovered from adult female rats. Numerous cellular lipid vacuoles and lamellar structures were observed in these alveolar macrophages under transmission electron microscopy. There was approximately 50% increase of cellular total lipid content measured by Oil-Red-O staining and colorimetric method. The yeast phagocytosis and intracellular killing ability, as well as the inhibitory effect on the growth of tumor cells were reduced in alveolar macrophages from neonatal MSG-treated rats.
