In a previous histochemical study, high levels of acid phosphatase were found in the developing adrenal cortex of the golden hamster. The present study describes the cytochemical localization of acid phosphatase and thiamine pyrophosphatase in the adult animal. These localizations are then related to protein uptake by adrenal cortical cells using the exogenous horseradish peroxidase as a tracer protein. Animals were sacrificed at times ranging from 15 minutes to 24 hours after injection of peroxidase. The techniques described by Novikoff et al. were utilized for localization of acid phosphatase and thiamine pyrophosphatase.In acid phosphatase preparations (Fig. 1), dense bodies containing reaction product are found in the cytoplasm of most cortical cells and are often associated with small coated vesicles near the Golgi area. Acid phosphatase activity is present in cells of the zona glomerulosa as well as those of the other two cortical zones.

Acid phosphatase activities in a culture liquid and mycelial extract were studied in submerged cultures of the filamentous fungus Humicola lutea 120-5 in casein-containing media with and without inorganic phosphate (Pi). The Pi-repressible influence on the phosphatase formation was demonstrated. Significant changes in the distribution of acid phosphatase between the mycelial extract and culture liquid were observed at the transition of the strain from exponential to stationary phase. Some differences in the cytochemical localization of phosphatase in dependence of Pi in the media and the role of the enzyme in the release of available phosphorus from the phosphoprotein casein for fungal growth were discussed.
