The Germ Similarity in Ontogeny of Ciliates (Ciliophora)
The paper deals with the regularities of ontogenesis of mobile and sessile ciliated protozoans. It is shown, that the germ similarity is characteristic both in mobile and sessile ciliates. The mechanisms of controlling of morphogenesis in ciliates are probably homologues with the controllers of early morphogenesis in multicellular organisms. The special statement for the case of law of germ similarity in unicellular eucaryots named "principle of tomits similarity" has been offered.Π ΡΡΠ°ΡΡΠ΅ ΡΠ°ΡΡΠΌΠ°ΡΡΠΈΠ²Π°ΡΡΡΡ ΠΎΡΠΎΠ±Π΅Π½Π½ΠΎΡΡΠΈ ΠΎΠ½ΡΠΎΠ³Π΅Π½Π΅Π·Π° ΠΏΠΎΠ΄Π²ΠΈΠΆΠ½ΡΡ

Early developmental dynamics of cell surface glycoconjugates in the rat left ventricle myocardium relate to the tissue stereological data
The purpose of study was to reveal the connection between the dynamics of cellular surface glycoconjugates (detectable
by binding plant lectins: PNA, LCA, RCA I, UeA, WGA) and stereological parameters (volume densities of cardiac muscle cells,
capillaries and connective tissue) in the left ventricle myocardium of rat heart in early ontogenesis.
The weak RCA I binding was observed in the membranes of cardiac myocytes of left ventricle throughout 12-20th days
of gestation. There was the moderate reaction with RCA I, LCA and WGA on cellular surface of vascular endothelium, pericardial
mesothelium and endocardial luminal cells. LCA and WGA staining revealed the uniform pattern for cardiac muscle cells within
the left ventricle myocardium. The weak UeA binding in the cardiac muscle cells appeared after 16th day of gestation in the
subepicardial layer of myocardium.
PNA binding was not uniform during 14-18th days of gestation in cardiac muscle cells. It was corresponded the stereological
differences in regions with the high and low receptors density. During this period, the volume densities of cardiomyocytes and
capillaries were higher in areas with strong PNA binding (subepicardial and intramural layers). The volume density of connective
tissue was high in areas with weak reaction (subendocardial region). The irregularity in PNA staining of cardiac muscle cells
in the left ventricle myocardium disappeared to 20th day of gestation together with Π° loss of statistical difference in the volume
densities of structural components in layers of myocardium
Spirochona americana sp. n. (Ciliophora, Chonotrichia) β a New North American Freshwater Chonotrich Species from the Amphipod Gammarus lacustris
Spirochona americana Dovgal, sp. n. is described from specimens collected in Pyramid Lake, Alberta, Canada. The chonotrich was found colonizing the gills of the gammarid amphipod Gammarus lacustris. S. americana differs from eight other species of the genus Spirochona in the ratio of cell length to cell width, cell body shape, size and morphology of the peristomal funnel, maximum cell size, and geographical distribution.ΠΠΏΠΈΡΠ°Π½Π° Spirochona americana Dovgal, sp. n.

Acineta persiensis sp. n. (Ciliophora, Suctorea) β a New Freshwater Suctorian Species from the Water Mites of the Genus Protzia (Acari, Hydrachnidia)
Acineta persiensis Dovgal et Pesic, sp. n. β a new suctorian ciliate species, was described from specimens collected in Guik stream, Khorrasan Province, Iran and in Stream Bistrica near village Crkvine, Montenegro. The suctorian was found colonizing the legs of the hydrachnid mites Protzia sepasgosariani and P. invalvaris. A new species differs from other species of the genus Acineta in the lorica structure, stalk morphology, the ability to hyperphoretic pseudocolonies formation and geographical distribution.ΠΠΏΠΈΡΠ°Π½ Π½ΠΎΠ²ΡΠΉ Π²ΠΈΠ΄ ΡΡΠΊΡΠΎΡΠΈΠΉ, Acineta persiensis Dovgal et Pesic, sp. n., ΠΏΠΎ ΠΌΠ°ΡΠ΅ΡΠΈΠ°Π»Π°ΠΌ ΠΈΠ· ΠΏΠΎΡΠΎΠΊΠ° ΠΠΆΡΠΊ, ΠΏΡΠΎΠ²ΠΈΠ½ΡΠΈΡ Π₯ΠΎΡΠ°ΡΠ°Π½, ΠΡΠ°Π½ ΠΈ ΠΏΠΎΡΠΎΠΊΠ° ΠΡΡΡΡΠΈΡΠ° Ρ Π΄Π΅ΡΠ΅Π²Π½ΠΈ Π¦ΡΠΊΠ²ΠΈΠ½, Π§Π΅ΡΠ½ΠΎΠ³ΠΎΡΠΈΡ.

Comparative Morphology of Dendrocometes paradoxus (Ciliophora, Suctorea) from two Distant Regions (Ukraine and Mexico) and Different Host Species
Comparative analysis of Dendrocometes paradoxus Stein, 1852 cell morphology from various gammarid amphipod species in different regions of Ukraine, and those attached to several host body parts of Hyalella azteca collected in two Mexican lakes, was carried out in order to demonstrate the morphological variability, due to the hosts species or their geographical distribution. For hosts species and corporal distribution, no significant differences between the two populations were shown. As the result, it was found the suctorians common for amphipod crustaceans from Ukraine and Mexico all are conspecific and belong to D. paradoxus.ΠΡΠΈΠ²ΠΎΠ΄ΡΡΡΡ ΡΠ΅Π·ΡΠ»ΡΡΠ°ΡΡ ΡΡΠ°Π²Π½ΠΈΡΠ΅Π»ΡΠ½ΠΎΠ³ΠΎ Π°Π½Π°Π»ΠΈΠ·Π° ΠΌΠΎΡΡΠΎΠ»ΠΎΠ³ΠΈΠΈ ΡΡΠΊΡΠΎΡΠΈΠΈ Dendrocometes paradoxus Stein, 1852 ΠΈΠ· ΡΠ°Π·Π»ΠΈΡΠ½ΡΡ
