Acylphosphatase activity and content were measured in erythrocytes from hyperthyroid patients and healthy controls. In addition, the soluble enzymes glucose-6-phosphate dehydrogenase, hexokinase, and the membrane bound (Na+ + K+)-ATPase and Ca2+-ATPase were assayed. Our results confirmed previous studies indicating a decrease of (Na+ + K+)-ATPase and an increase of Ca2+-ATPase activity in hyperthyroid erythrocytes. While glucose-6-phosphate dehydrogenase was not significantly changed, hexokinase and acylphosphatase activities were significantly higher in the hyperthyroid group. Both activities and content of acylphosphatase returned to normal levels in erythrocytes from treated patients, when they were euthyroid. These findings suggest that an excess of thyroid hormones may stimulate acylphosphatase biosynthesis in erythroid cells and indicate a potential clinical usefulness of this enzyme in hyperthyroidism.

The post-mortem stability of some brain enzymes was studied. Over the time period under examination, the cytoplasmic enzymes investigated underwent a decisive decay, hexokinase being the most labile and acylphosphatase the most stable. On the other hand, structured activities such as Na+, K+-ATPase and Ca2+, Mg2+-ATPase showed an apparent transitory increase. The differences in post-mortem stability of soluble enzymes could be ascribed, at least in part, to their different susceptibility toward proteolytic activities, as suggested by the electrophoretic results.
