“…Many types of histochemical enzyme techniques were applied to vaginalis and published in a series of papers by Sharma and Bourne (Sharma and Bourne, 1963, 1964a, 1964b, 1966a, 1966b. Results are summarized: Succinic dehydrogenase and cytochrome oxidase (low levels), NAD and NADP-linked diaphorases (mitochondrial flavoprotein ox idizing NADH2 AND NADPH2), isocitrate, malate, glutamate, a-glycerophos phate, and lactate dehydrogenases, and acid and alkaline phosphatases were localized in "mitochondrial granules", ^-glucuronidase, dopa oxidase, and glycosan (glycogen) phosphorylase were found to be cyto plasmic, and 5'nucleotidase and urease in non-mitochondrial granules.…”
