| [the oncomiricidium of diplozoon nipponicum goto, 1891. a new type of larval haptor for the genus diplozoon (monogenea, discocotylidae)]. | diplozoon nipponicum goto 1891, a branchial parasite of cyprinus carpio is mentioned for the first time in france and western europe. carps, along with their monogenea, were introduced from hungary. after being obtained experimentally, the oncomiracidium is thoroughly studied (excretory system, ciliated cells, chaetotaxy, haptor). a new haptor for the genus diplozoon is described: two pairs of larval lateral hooklets are present. the taxonomic and phylogenic implications of these observations ar ... | 1982 | 7168525 |
| gaba-mediated negative feedback from horizontal cells to cones in carp retina. | in the isolated, perfused retina of the carp, properties of the feedback pathway from horizontal cells to cones were investigated by means of electrophysiological and neuropharmacological methods. when horizontal cells were hyperpolarized by illumination with an annulus, a depolarizing synaptic potential was produced in cones at the center of the annulus, suggesting that horizontal cells receive inputs from cones and exert a negative feedback to cones. on the other hand, a hyperpolarization (eps ... | 1982 | 7169699 |
| gaba-mediated negative feedback and color opponency in carp retina. | in the isolated, perfused retina of the carp, the effects of gaba and its antagonists, picrotoxin and bicuculline, were investigated on spectral responses of horizontal cells. when the gaba-mediated feedback from horizontal cells to cones was desensitized or blocked by these chemicals, remarkable changes were observed in spectral responses, due to selective suppression of responses to long wavelengths. in particular, the depolarizing responses in the biphasic c-type (h2) cell were abolished, whi ... | 1982 | 7169700 |
| functional regeneration of the visual system in teleosts. comparative investigations after optic nerve crush and damage of the retina. | goldfish and carp are shown to be capable of functional reconstitution of the visual system, although their neural retina except of the marginal growth zone at the ora serrata was completely destroyed by injection of the na-k-atpase inhibitor ouabain. this was demonstrated by the observation of the recovery of the optokinetic nystagmus after damage of the retina. recovery of vision coincides well with the morphological reconstitution of the visual system. the regenerated axons within the optic n ... | 2016 | 7183033 |
| biochemical compartmentation of fish tissues. hexokinase in the brain. | differential distribution of gross, particulate and soluble forms of hexokinase in the cerebrum, cerebellum, pituitary, hypothalamus and thalamus and medulla oblongata was studied in 9 inland teleosts of different phylogenetic age to clarify the compartmentation of glucose metabolism. enzyme activity (gross) was maximum in the cerebrum and minimum in the medulla oblongata, suggesting that glucose metabolism is more intensive in the former structure. the activity in the particulate fraction was h ... | 1982 | 7187168 |
| presence of liver-forming fraction in fish egg mrnas detected by its ability to encode albumin synthesis. | poly a attached rnas were isolated from carp ovarian and mature eggs. both were equally potent in cell-free translating wheat germ system. the products were analyzed with rabbit antiserum against carp albumin and polyacrylamide gel electrophoresis. the results revealed the presence of carp albumin, a liver specific protein. | 1980 | 7190727 |
| separation of subunits of pike eel gonadotropin by hydrophobic interaction chromatography. | subunits of pike eel gonadotropin were dissociated in propionic acid and separated by hydrophobic interaction chromatography on phenyl-sepharose cl-4b with a high yield (79%). isolated subunits were homogeneous, as tested by sodium dodecyl sulphate disc electrophoresis and by n-terminal analysis. the biological activities of two subunits, s-i and s-ii, were 0% and 2.8% of native molecule, respectively, as assayed by stimulation of androgen production on carp testes. reassociated molecules restor ... | 1981 | 7198649 |

| the uptake of zinc, lead, copper and manganese by carp fed with activated sludge. | the incorporation of 10 or 40% of activated sludge improved the growth rates of common carp, cyprinus carpio, by comparison with those receiving a commercial fish feed (tubifex worms) alone. the incorporation of 70% or 85% sludge, however, yielded very poor growth rates. the visceral organs of fish receiving 70 or 85% sludge contained 2 x zinc (zn), 2.5 x copper (cu) and 1.4 x manganese (mn) of the control group. | 1981 | 7222114 |
| electroencephalographic analysis of activities in the optic tectum of unrestrained carp. | electroencephalographic activity of the optic tectum in unrestrained resting carp was classified into three dominant frequency ranges of 4-7, 8-13 and 14-25 hz, peaking at 6, 10, and 17 and 22 hz, respectively, under power spectral analysis. all these activities were suppressed in the dark. the suppression was most prominent in the 8-13 hz waves, but less so in the 4-7 hz. however, while the fish was swimming actively, the 4-7 hz spectrum increased in power and no actual increase could be observ ... | 1981 | 7225222 |
| proton nuclear magnetic resonance determination of the sequential ytterbium replacement of calcium in carp parvalbumin. | the substitution of the paramagnetic lanthanide ion ytterbium for the calcium ions bound to the cd and ef sites of carp parvalbumin results in a series of 1h nmr resonances which are shifted far outside the envelope of the 1h nmr spectrum of the diamagnetic form of the protein. titration of ca2+-saturated parvalbumin with ytterbium (yb3+) demonstrate that yb3+ sequentially replaces the two bound calcium ions of the protein. analysis of the 1h nmr data yields the relative affinities of the two si ... | 1981 | 7225322 |
| dendritic bundles: occurrence and regeneration in the forebrain of the japanese carp, cyprinus carpio. | dendritic bundles were observed in the striatum and cerebellum of the japanese carp. the striatal bundles were found to regenerate following telencephalic removal. this finding in conjunction with incoming axonal budding suggests that formation of the bundles are under the control of dynamic biological factors and not simple mechanical distortions. | 1980 | 7229343 |
| does rigidity in structure of muscarinic agonists and antagonists reflect drug specificity? | the present work is an attempt to elucidate: (1) whether highly rigid structural analogs of acetylcholine are still capable of activating the muscarinic receptor; (2) whether such analogs, be they agonists or antagonists, discriminate among the various ach-mediated functions, thereby providing a tool for the study of a possible receptor heterogeneity; (3) whether structural rigidity is a significant factor in the kinetics of drug-receptor interaction. to this end, we investigated some properties ... | 1980 | 7231438 |
