[Quantitative criteria of a rhinocytogram of healthy subjects]. / Kolichestvennye kriterii rinotsitogrammy zdorovogo cheloveka.

Presents qualitative and quantitative characteristics of normal rhinocytograms obtained by cytologic investigations of smears impressions from the surface of the anterior portion of the inferior turbinate bone and processing of the results by variation statistics methods. Actually only solitary scales and superficial cells of multilayer squamous epithelium and small groups of ciliary epithelium cells may be reliably present in a normal rhinocytogram of man.

[Morphology of the intranuclear inclusions in Entamoeba histolytica trophozoites]. / Morfologiia vnutriiadernykh vkliuchenii trofozoitov Entamoeba histolytica.

Electron microscope studies of spherical intranuclear inclusions (II) of Entamoeba histolytica trophozoites of two strains, which were maintained in polyxenous culture for different periods of time, were carried out. Data on the number of II in different individuals and in different strains are given. The structure of II whose external layer consists of electron dense material and resembles morphologically peripheral chromatin of the ameba's nucleus, an analogy of nucleolus chromatin of cells of other eucariots, is considered. Inside this layer some II have annular filaments about 9 nm thick rolled up spherically around the central zone of II. Comparison of results obtained and literary data suggests that the dynamic structure of II in question reflects a number of biosynthetic processes on the basis of annular extrachromosomal DNA of exogenic origin.
