| parvalbumin in skeletal muscles of teleost (tinca tinca l. and misgurnus fossilis l.). histochemical and immunohistochemical study. | musculatures of two fish species belonging to the suborder cyprinoidei were examined histochemically and immunohistochemically for demonstration of matp-ase activity and parvalbumin content, respectively. the tench lateral musculature shows a typical "acid reversal" picture of matp-ase activity--red fibres are alkali labile, acid stable and white and white fibres are alkali stable, acid labile. in the pond loach a superficial layer of musculature is composed of alkali--and acid stable red fibres ... | 1992 | 1483535 |
| comparative study of the anatomy and laminar organization in the olfactory bulb of three orders of freshwater teleosts. | the anatomy and lamination of the olfactory bulb in cyprinus carpio, tinca tinca, barbus bocagei (fam. cyprinidae, or. cypriniformes); salmo gairdneri (fam. salmonidae, or. salmoniformes); and gambusia affinis (fam. poeciliidae, or. cyprinodontiformes), all of them freshwater teleosts, are studied. these species show significative differences on the location, size, morphology, and lamination of their olfactory bulbs. the presence of a new stratum in the olfactory bulb of salmo gairdneri and a co ... | 1989 | 2759410 |
| acetylcholinesterase in the alimentary canal of fish: light and electron microscopic detection, quantitative distribution in different segments of the gut. | the acetylcholinesterase activity was measured and histochemically localized in the alimentary tract of 2 fish species, carp (cyprinus carpio) and tench (tinca tinca). a comparison was made of the activities in the different gut segments. light and electron microscopic histochemistry revealed acetylcholinesterase-positive cell bodies along the entire length of the alimentary canal in both species, between the muscular layers. acetylcholinesterase-positive, cholinergic motor endplates were freque ... | 1989 | 2516680 |
| enteric neuromuscular junctions: comparison of ultrastructural features in different phylogenetic groups. | the enteric neuromuscular junctions of snail (helix pomatia), locust (locusta migratoria migratorioides), cockroach (periplaneta americana), carp (cyprinus carpio) and tench (tinca tinca) were studied by means of different light and electron microscopic methods. the nitroblue tetrazolium staining revealed that the myenteric plexuses of the above species are composed of nerve cells, a network of varicose nerves and nerve bundles. instead of highly organized ganglia, single neurons or small groups ... | 1988 | 3393275 |

| new aspects on the 'rodlet cell' in teleosts. | the enigmatic rodlet cells, hitherto interpreted mainly as unidentified parasitic stages ('rhabdospora thélohani') or as a sort of secretory cell, have been studied with electron microscopical and histochemical methods in three teleost species (cyprinus carpio l., tinca tinca l., salmo gairdneri rich.). the typical inclusions, the rodlets, consist of a dense core and a less dense cortex, with a coarse flocculent outer zone. the latter shows a positive reaction for neutral polysaccharides respect ... | 1983 | 6876223 |
| developmental stages and localization of peroxidatic activity in the leucocytes of three teleost species (cyprinus carpio l.; tinca tinca l.; salmo gairdneri richardson). | the ultrastructural localization of peroxidase (po) in the leucocytes of three teleosts (cyprinus carpio l., tinca tinca l., salmo gairdneri r.) has been investigated using the 3,3'-diaminobenzidine method. in the heterophilic granulocytes the granules show a species specific structure and are po-positive at ph 7.6. they can be traced back to small granules arising near the golgi apparatus (ga) in the promyelocyte. they coalesce to form larger granules and gradually change into the mature type. ... | 1981 | 7273125 |
| temperature and reproduction in tench: effect of a rise in the annual temperature regime on gonadotropin level, gametogenesis and spawning. i. the male. | during a 9-month period (corresponding to a sexual cycle), the adult male tench, tinca tinca, was kept in fish farm ponds receiving heated water from a power plant. in 1974, the males were submitted to three different temperature regimes: group i: ambiant temperature; group ii: ambiant temperature +3 degrees c; group iii: ambiant temperature + 6 degrees c. the experiment was repeated in 1975, but only using groups i and iii. the reproductive cycle and thermal treatment were studied from a quanti ... | 1980 | 7349412 |
| [the rodlet cells of some species of freshwater and marine bony fishes of orders cypriniformes and perciformes]. | the fine structure of rodlet cells from pronephros of cobitis taenia (l.), mesonephros of tinca tinca (l.), rutilus rutilus (l.), stizostedion volgense (gmelin), stizostedion lucioperca (l.), perca fluviatilis (l.), trachurus mediterraneus (staindachner) and diplodus annularis (l.) was studied. in the organs examined, cells at developmental stages iii, iv and v were detected. it is shown, that the rodlet cells have the structural organization similar to that described in different organs of fish ... | 2011 | 21539089 |

| [assessment of pathological changes in fish muscle tissue, forming as a result of exposure to toxic factors in the environment]. | our investigation of muscle tissue of fishes, inhabiting the regions with unfavorable ecological conditions (the river volga), permitted to select four types of degenerative changes in muscle tissue. these alterations are associated with both the phylogenetic status of fish species and ecological dispositions of species. using different methods of investigation several types of muscle destruction were shown. i. destruction of myofibrillar apparatus (lysis of protofibrils), with sarcolemma remain ... | 2000 | 10709249 |
| substance p-like immunoreactivity in the ganglion cells of the tench terminal nerve. | the distribution of substance p (sp) in the olfactory bulb of the tench tinca tinca was studied by using an indirect immunoperoxidase technique. many perikarya and processes of the ganglion cells of the nervus terminalis (nt) were strongly labeled. in addition, sp-like immunopositive fibers were observed in the proximity of these neurons and extending along the olfactory nerves and the olfactory tracts. the ganglion cells of the nt were not immunoreactive for methionine- and leucine-enkephalin, ... | 1989 | 2481248 |
