  • Abstract
  • Look Inside

Previous studies have demonstrated that rats treated with a proteinase inhibitor, leupeptin (Leu),show an accumulation of lipofuscin (Lf)-like dense bodies in the neurons. The present study examines the quantitative and ultrastructural changes in the Lf-like dense bodies of Purkinje (P) cells and Bergmann (B) glia over 20 days following a 4-day regimen of Leu administration by intracisternal infusion. Toluidine blue staining revealed consider-able Lf-like granules in both types of cells 1 day after Leu infusion. However, these granules had almost disappeared by 20 days after infusion.
