title: Endogenous peroxidatic activity in the cerebral and cerebellar cortex of normal adult rats.
abstract: There are at least three sources of endogenous peroxidatic activity that are present in both the cerebral and the cerebellar cortex. All three sources, being neuronal, astrocytic or hemoglobin-dependent, may obscure the interpretation of studies using exogenous horseradish peroxidase. The activities are to a variable extent influenced by fixation. From the present results DAB-incubation of cryostate sectioned brain appears to be an acceptable method for histochemical demonstration of the mitochondrial cytochrome chain enzymes.
