Abstract
Recent morphological studies of E. histolytica have revealed the presence of several intranuclear structures which are clearly distinguished from other nuclear components. These are round membrane bound bodies of variable marked electron density averaging from 15 to 40 milimicra in diameter (Fig. 1). Their intranuclear location and persistance within the nucleus along the various stages of the life cycle of E. histolytica seems to indicate that these structures may have a functional role in the nucleus. The present study was undertaken to determine the existence of DNA and RNA in this intranuclear structures.Trophozoites of E. histolytica ABRM strains obtained from monoxenic cultures were fixed for 35 minutes in 2.5% Glutaraldehyde, 0.1M sodium cacodilate buffer.
