RESUMO
The lead method for the histochemical demonstration of presumptive mitochondrial adenosinetriphosphatase was applied to biopsy and autopsy samples of the human vastus lateralis muscle. The effect of p-chloromercuribenzoate and of Triton X-100 was tested microdensitometrically and the activity of 'mitochondrial' ATPase was compared to the activity of enzymes of the oxidative metabolism succinic dehydrogenase and NAD-tetrazolium reductase. It is concluded that the ATPase activity displayed is not mainly mitochondrial. In autopsy material, it seems to be predominantly myofibrillar.
