Lysosomal acid hydrolases play an imperative part in the initiation of inflammation processes associated with myocardial infarction. In the present investigation, we have studied the protective effect of L-glutamine on isoproterenol-induced myocardial damage in male albino rats with respect to alterations in lysosomal function. The myocardial infarction in experimental animals was induced by in...

Lamellar bodies and lysosomes from the lungs of rabbits were examined for the presence of 24 hydrolytic enzymes. All hydrolases detectable in lysosomes were also found in lamellar bodies. Hydrolase activities in lamellar bodies were not due to contamination with lysosomes as shown by isopycnic centrifugation of the subcellular organelles on continuous density sucrose gradients. Lysosomal prepar...
