INTERPRETATION OF MORPHOLOGICAL PICTURE OBSERVED IN HISTOLOGICAL PREPARATIONS FROM THE POINT THE VIEW OF STEREOLOGY

The study of a biological microobject from the standpoint three-dimensionality gives more correct and realistic vision. material included 8 preparations palatine labial salivary glands adult human individuals fixed in 4% glutaraldehyde solution phosphate buffer (pH 7.4). Following pre-fixation, object was cut into individual slices freshly prepared similar fixator adding 1% calcium chloride at 4 °C for 12 hours. tissue washed after fixation then processed according to requirements electron microscopy. Tissues enclosed epoxy resin were used obtain semi-thin series histological sections further graphic plastic reconstruction epithelial components (including tubular) glands. Semi-thin stained with 0.1% toluidine blue different pH (from 5.5 8.5). Spiral, corkscrew, tortuous, arched other forms tubular structures microscopic level are no exception and, as our shows, natural phenomena along their rectilinear shape. It can be assumed that interdependence between shape transport microchannels laminar motion fluid naturally reflects elements curvilinear symmetry particular, its spiral property. Conclusion. Thus, we could assume tortuous channels animal tissues is useful stereomorphological device, three-dimensional modelling great scientific interest, understanding mechanism movement through tubes.
