[Lysosomal enzyme activity in the serum of rats with experimental lead poisoning]

Examination of the effect of experimental lead poisoning on permeability of lysosomal membranes in albino rats demonstrated activation of lysosomal enzymes (alpha-manosidase and beta-acetylglucosaminidase) in the blood serum as soon as the third day after daily administration of lead acetate (20 mg/kg). Apparently damage of the lysosomal membrane played an important role in the pathogenesis of lead poisoning.
