[Ultracytochemical study of activity of various phosphatases during early postmortem period in experimental animals]

The activities of acid phosphatase (AP), glucose-6-phosphatase (G-6-P), and thiamine pyrophosphatase (TPP) were assayed in the epithelial cells of the main bronchi and hepatocytes of rats within 1 to 5 hours after their death. In the postmortem period, some enzymes (AC, G-6-P) retained their activity while the others (TPP) were inhibited. Furthermore, there were unusual intracellular sites of AP reaction products.
