Activities of acid phosphatase and beta-glucuronidase in the cerebella of young jaundiced (j/j) and non-jaundiced (j/+; control) Gunn rats were studied with the enzyme histochemical method. The cerebellum of j/+ rats showed high acid phosphatase activities in Purkinje cells and neurons in the cerebellar nuclei. In j/j rats, a number of neurons were lost and numerous microglialike cells with a high acid phosphatase activity appeared in the hypoplastic cerebellum. Although beta-glucuronidase activity was rarely detected in the control cerebellum, a high enzyme activity was observed associated with microglialike cells in j/j rats. The present results provide a cytological basis for the reported differential increase in the activities of these lysosomal enzymes in the j/j rat cerebellum.
