SYNOPSIS. Changes in macromolecular content and certain enzyme levels have been studied during excystment of Schizopyrenus russelli. Protein, RNA and DNA increase with the onset of excystment, the increase being more marked in the first 2 hr than later. Cellulose content is considerably decreased as the trophozoites start emerging from the cysts. There is no significant change in glycogen content. Enzyme activities of glutamic oxalacetic transaminase and ribonuclease increase while those of aldolase and isocitric dehydrogenase decrease as excystment proceeds.
