investigations on the protonephridial system of post-larval gyrocotyle urna and amphilina foliacea (cestoda).the gross morphology and ultrastructure of the different parts of the protonephridial system of the monozoic tapeworms gyrocotyle urna and amphilina foliacea are described. the terminal cell in both species has numerous cilia which are interconnected and extend into the lumen of the first canal cell. the filtration area is built up from projections of two cells, the terminal cell and the first canal cell. the first canal cell forms a solid hollow cylinder without a cell gap and a desmosome as fo ...19921639564
the nervous system of amphilina foliacea (platyhelminthes, amphilinidea). an immunocytochemical, ultrastructural and spectrofluorometrical study.the nervous system of young and adult amphilina foliacea was studied with immunocytochemical, electron microscopical and spectrofluorometrical methods. the general neuroanatomy is described in detail. new data on the structure and development of the brain were obtained. the 5-ht and gyirfamide-immunoreactivities occur in separate sets of neurones. the innervation of the reproductive organs is described. the fine structure of 2 types of neurones in the cns, a sensory neurone, a 'glial' cell type, ...200011072908
the ultrastructure of glia-like cells in lateral nerve cords of adult amphilina foliacea (amphilinida).the ultrastructure of main lateral nerve cords (mcs) of adult a. foliacea was studied. by examination of the serial sections it has been found that some glia-like cells are located on a periphery of mc. the processes of glia-like cells surround mcs and penetrate into the cord and surround the group of adjacent axons and pairs of neurones. there is a fine extracellular matrix between processes of glia-like cells. the numerous tight junctions occur between processes. the difference between the per ...200011034168
sensory organs of adult amphilina foliacea (amphilinida).the distribution and morphological diversity of the sensory structures on the body surface, proboscis and caudal cavity of adult amphilina foliacea have been investigated. fifteen different types of receptors are described. along with nonciliated and uniciated receptors bi- and multiciliated receptors have been found for the first time. the zonal distribution of the sensory structures and their coincidence within the same areas of the body surface have been revealed. the concentration of sensory ...200011034167
[konstanty janicki: scientist, university professor, discoverer].janicki born in moscow (1876) lived in warsaw up to graduation from high school (1893). then he emigrated to the western europe for the next 25 years. janicki had studied and curried out scientific researches in the field of helminthology and protozoology at universities and institutes in germany, switzerland and italy. in 1918 poland reagained independence and konstanty janicki returned from abroad to warsaw. he was nominated as a professor and chairman of the department of systematic and morph ...200516913508
[fine structure of glial cells in the central nervous system of the tapeworm grillotia erinaceus (cestoda: trypanorhyncha)].the problem of glial cells existing in parasitic and free living flatworms is correlated with organization of parenchyma in platyhelmintes. in the contrary to the widespread opinion that myelin-like envelopes and glial cells do not exist in the nervous system of parasitic flatworms, it has been shown by ultrastructural researches that amphilina foliacea (cestoda, amphilinidea) has well developed glial cells and myelin-like envelopes in the ganglia and main cords, which include both glial cells a ...200818727401
helminth parasites of stellate sturgeon acipenser stellatus pallas, 1771 and persian sturgeon acipenser persicus borodin, 1897 (pisces: acipenseridae) from the south-east caspian sea.a total of 182 specimens of two sturgeon species, stellate sturgeon acipenser stellatus (n=112) and persian sturgeon acipenser persicus (n=70), from three coastal stations in the south-east caspian sea were examined for endohelminth parasites. four helminth species were recorded: cucullanus sphaerocephala (nematoda: cucullanidae) and skrjabinopsolus semiarmatus (digenea: acanthocolpidae), found in both host species, and leptorhynchoides plagicephalus (acanthocephala: rhadinorhynchidae) and amphi ...200818317807
spermatozoon cytoarchitecture of amphilina foliacea (platyhelminthes, amphilinidea).the mature spermatozoon of amphilina foliacea rudolphi, 1819 has been examined using transmission electron microscopy. the male gamete is filiform and tapered at both extremities. its moderately electron-dense cytoplasm possesses two parallel axonemes of unequal lengths with the 9 + "1" trepaxonematan pattern, a mitochondrion, a nucleus, parallel cortical microtubules, four electron-dense attachment zones, and electron-dense glycogen granules. a crested body is absent. the anterior extremity of ...201222932939
a reinvestigation of spermiogenesis in amphilina foliacea (platyhelminthes: amphilinidea).spermiogenesis in the amphilinidean cestode amphilina foliacea (rudolphi, 1819) was examined using transmission electron microscopy. the orthogonal development of the two flagella is followed by a flagellar rotation and their proximodistal fusion with the median cytoplasmic process. this process is accompanied by extension of both the mitochondrion and nucleus into the median cytoplasmic process. the two pairs of electron-dense attachment zones mark the lines where the proximodistal fusion of th ...201323539951
[ultrastructural characteristics of the vitellaria, uterus and vagina of amphilina foliacea rudolphi, 1819 (cestoda: amphilinidea)].the ultrastructural features of the vitelline follicles, uterus and vagina of the amphilinid cestode amphilina foliacea from the body cavity of acipenser ruthenus of the volga basin are described. some new distinguishing characters are revealed, including the presence of a single type of the cellular component in the vitelline follicles with sarcoplasmic processes filling the space around and within vitellocytes. the,uterus of this species is recognized by the presence of the syncytial epithelia ...201425464739
