[The effect of chronic aluminum loading on lysosomal enzymes in serum and organ homogenates. Methodologic aspects]

The influence of aluminium administration both on the lysosomes and on the activity of DNA-dependent enzymes in rats with intact kidney function or following partial nephrectomy was investigated. The elevation in free N-acetyl-beta-D-glucosaminidase in connection with a decrease of latent beta-NAG-level in liver, spleen and kidneys may be supposed a dose dependent aluminium damage of the lysosomes. Moreover, the decrease of free and total beta-glucuronidase in the liver and spleen could be caused by a selective inhibition of synthesis of this enzyme.
