| neuronal architecture of on and off pathways to ganglion cells in carp retina. | bipolar, amacrine, and ganglion cells of carp retina, stained intracellularly with procion yellow, can be divided into types a and b, according to the destination of terminals and dendritic trees in the inner plexiform layer (sublamina a and b, respectively). type a cells showed hyperpolarizing, or off, responses and type b cells depolarizing, or on, responses. carp thus resembles cat in the basic organization of on and off pathways in the retina. | 1977 | 73223 |
| relation between carp (multiple-sclerosis associated) agent and multiple sclerosis. | it is suggested that the carp (multiple-sclerosis associated and scrapie associated) agents may be the v-r.n.a. form of slow (d.n.a.) viruses which are the aetiological agents of the two diseases. | 1976 | 73745 |
| polymorphism of parvalbumins and tissue distribution: characterization of component i, isolated from red muscles of cyprinus carpio l. | the component i isolated from carp red muscle has been characterized as a true parvalbumin, fairly different from carp parvalbumins described so far. the protein is antigenically related to the parvalbumin iii from pike, which belongs to the so called parvalbumin lineage alpha. immunological investigations on the location of the various carp parvalbumins reveal genuine variation in the pattern of these proteins according to organ and type of muscular tissue. | 1978 | 75026 |
| pituitary cytology of the indian carp labeo rohita (ham.). | in the adenohypophysis of labeo rohita eight cell types could be identified on the basis of their different tinctorial response to various staining techniques. the rostral pars distalis has 3 types of cells. type 1 is stained with erythrosin, orange g, and acid fuchsin. type 2 cells are lead hematoxylin positive and give an amphiphilic reaction in response to tri and tetrachrome techniques. type 3 cells are stainable with pas, ath, ab, af, and aniline blue and are distributed in an area comprise ... | 1977 | 76451 |
| retinal ganglion cells in the crucian carp (carassius carassius). i. size and number of somata in eyes of different size. | ganglion cell somata were drawn, measured and counted in flat-mounted crucian carp and goldfish retinas stained with cresyl violet or methylene blue. some diameter histograms suggest that the ganglion cells can be divided into two populations with overlapping soma sizes: a large group of small cells and a small group of large cells, the latter constituting 2.5-5% of all ganglion cells. with increasing distance from the optic disc the mean soma diameter increases while the ganglion cell density d ... | 1978 | 76639 |
| isolation and characterization of the three light chains from carp white muscle myosin. | myosin from carp white muscle contains two mol of "dtnb" light chain (mol. wt 17 500 daltons) and two mol of "alkali" light chains (mol. wt 25 000 and 16 400 daltons). the three light chains have been isolated in pure state and characterized by electrofocusing, ultraviolet absorption, amino acid analysis and tryptic peptide mapping. our results show a great homology between the two carp alkali light chains whereas lc2 seems chemically more different. but the homology of lc1 and lc3 is not so ext ... | 1977 | 79371 |
| horizontal cells of the carp retina: golgi impregnation and procion-yellow injection. | application of two methods for the selective staining of neurons, golgi impregnation and intracellular marking with procion yellow, has revealed the anatomical arrangements of the horizontal cells in the carp retina. there are two basic horizontal-cell types, those with axons and these without. the former can be subdivided into three groups on the basis of the pattern of branching of the dendrites. these three structural groups are also functionally distinct, as shown by the electrical recording ... | 1978 | 83194 |
| molecular adaptability of carp myosin: a study of some physico-chemical properties and their comparison with those of rabbit myosin. | during thermal inactivation, the addition of as low as m urea resulted in the reduction of delta g identical to barrier of the inactivation of carp myosin ca2+-atpase, whereas that of rabbit myosin remained unaffected. in the absence of urea, a four-hour incubation of carp myosin was accompanied by the release of light chains at 30 degrees c, a value 10 degrees c lower than that for rabbit myosin. electron micrographs revealed that carp myosin forms artificial thick filaments, which were uniform ... | 1979 | 93883 |
| [structural and immunochemical studies of carp (cyprinus carpio l.) immunoglobulin. v. tryptic fragments of carp (cyprinus carpio l.) immunoglobulin m]. | carp igm, isolated from normal serum is more sensitive to trypsinization compared to a human myeloma protein igmgo. under the same conditions (treatment with trypsin at 56 degrees c for 30 min) carp igm was degraded to small, mostly dialysable peptides to a larger extent than igmgo. in both cases the fragmentation resulted in immunoelectrophoretically pure fab mu and fc mu fragments. the fab mu fragments of human igm (yield: 20% of used igm material) had a molecular weight of 54,000, the fc mu f ... | 1979 | 95144 |

| fluorescent and spin label probes of the environments of the sulfhydryl groups of porcine muscle adenylate kinase. | the environments of the two sulfhydryl groups of procine muscle adenylate kinase have been investigated by chemical modification reactions. the results indicate that the environments of the two-sh groups of procine muscle adenylate kinase are markedly different and that substrates induce conformational changes in the enzyme in the region of the sulfhydryl groups. the fluorogenic reagent 7-chloro-4-nitrobenzo-2-oxa-1, 3-diazole (nbd-chloride) reacts specifically with the -sh groups of the enzyme ... | 1975 | 163231 |
| crystalline adenylate kinase from carp muscle. | 1. the concentration of adenylate kinase in carp muscle is about 0.3 mg/g. an improved isolation procedure makes use of a dilute solution of the substrates, atp and amp, to elute the enzyme from a phosphocellulose column in overall yields of 60% before crystallization. by the hexokinase--ph-stat assay the specific activity is 3550 units/mg. the preparation has been found to be essentially homogeneous by dodecylsulfate gel electrophoresis, isoelectrofocusing and gel filtration. 2. the molecular w ... | 1975 | 164348 |
| structure-function relationships and mode of replication of animal rhabdoviruses. | recently accumulated knowledge allows more precise comparison of the structural (and possibly evolutionary) relationships of several different animal rhabdoviruses: vesicular stomatitis virus, rabies virus, kern canyon virus, and spring viremia of carp virus. each virus is composed primarily of a glycoprotein, an rna-associated nucleoprotein, and one or two membrane proteins. vesicular stomatitis virus group viruses contain lesser amounts of two additional distinct polypeptides, ns and l. the se ... | 1975 | 165494 |

| proprioceptive motor control in fish respiration. | the response of single respiratory neurones in the medulla oblongata of carp to short twitches of individual respiratory muscles were analysed. the muscle contractions were obtained through automatic electrical stimulation and could be consistently elicited in a predetermined phase relation to the ventilatory cycle. the results show that, apart from nerve cells which take part in long-term processing of proprioceptive information from several sources, neurones also exist which possess the proper ... | 1975 | 168305 |
| [exophthalmogenic effect of thyrotropin releasing hormone (trh) in the animal experiment]. | exophthalmos has been induced in carp by injecting thyrotropin releasing hormone (trh) (pyro-glutamyl-histidyl-prolinamide) into the coelom. this effect was dose-dependent (dose range 5-750 mug). it was significantly potentiated by prior administration of beta-1 minus 24 coricotropin (synacthen, ciba) and inhibited by prednisclone. no significant increase was obtained with 2-phenylalanine-8-lysire-vasopressin (octapressin, sandoz). the results show that in the fish model, trh exerts an exophthal ... | 1975 | 168634 |
| inactivation of rabbit, pig, and carp adenylate kinases by n6-o- and p-fluorobenzoyladenosine 5'-triphosphates. | n6-o- and p-fluorobenzoyladenosine 5'-triphosphates (iiic and iic, respectively) have been synthesized as potential adenosine 5'-triphosphate (atp) site-directed reagents for enzymes. iic and iiic were substrates of yeast hexokinase; neither they nor the corresponding adp derivatives inactivated yeast hexokinase or rabbit pyruvate kinase. iic rapidly inactivated rabbit and carp muscle adenylate kinases; the effect is probably atp site directed because n6-benzoyl-atp did not inactivate and was a ... | 1975 | 172123 |
| characterization of "pasteurella" piscicida isolated from white perch and cultivated yellowtail. | the morphological, physiological, and biochemical characteristics of twelve "pasteurella" piscicida strains isolated from white perch and yellowtail are described and the present uncertain taxonomic status of the organisms is discussed. the organisms isolated were gram-negative rods showing bipolar staining and pleomorphism. no spores or flagella were observed. they were non motile and viscid colonies were formed. growth was observed in a temperature range of 20 to 30 c and the salinity range of ... | 1975 | 172679 |
| effects of external ions on the synaptic transmission from photorecptors to horizontal cells in the carp retina. | 1. intracellular recordings were made from cones and horizontal cells of the isolated carp retina and the mechanisms of synaptic transmission from cones of horizontal cells were studied by changing the ionic composition of the external medium. 2. cones were depolarized and their light responses enhanced in low ca high-mg medium. in the same medium, in which chemical transmission is suposed to be blocked, horizontal cells were hyperpolarized and their light responses disappeared. 3. when the syna ... | 1975 | 173833 |
| cerebrospinal fluid-contacting neurons, ciliated perikarya and "peptidergic" synapses in the magnocellular preoptic nucleus of teleostean fishes. | the magnocellular preoptic nucleus of fishes (anguilla anguilla, amiurus nebulosus, cyprinus carpio, carassius auratus, ctenopharyngodon idella, cichlasoma nigrofasciatum) has been studied by light and electron microscopy. two kinds of neurons were found: a) large, electron-dense, gomori-positive cells with moderate acetylcholinesterase (ache) positivity which contain granulated vesicles of 1400 to 2200 a (in average 1600 to 1800 a), adn b) small, strongly ache-positive, electron-lucent neurons ... | 1987 | 174818 |
| the distribution of pyrophosphatidic acid in nature. | the occurrence of a novel phospholipid, pyrophosphatidic acid, in the lipid extracts of yeasts (23 species), bacteria (e. coli), algae (chlorella), mammalia (human, rabbit, guinea pig, and mouse), insect (cockroach), fish (carp), mollusc (clam), and spermatophyta (spinach) was investigated. pyrophosphatidic acid was found exclusively in the lipid extracts of several kinds of yeast species, but not in other normal living species (animals, plants, and microorganisms) so far investigated. all of th ... | 1975 | 175047 |
| evidence for species-specific substrate-site-directed inactivation of rabbit adenylate kinase by n6-(6-iodoacetamido-n-hexyl)adenosine 5'-triphosphate. | adenosine 5'-triphosphate (atp) derivatives bearing iodoacetylamino-n-alkyl substituents [(ch2)nnhcoch2i] on n6 were synthesized as potential atp-site-directed irreversible inhibitors of adenylate kinases from rabbit, pig, and carp muscle. when n was 5 no enzyme was progressively inhibited (inactivated) by 1 mm inhibitor under the test conditions (6 h at 0 degrees); when n was 6 the rabbit enzyme was 76% inactivated by 0.79 mm inhibitor whereas the pig and carp enzymes were unaffected by 2.76 mm ... | 1976 | 187748 |
| electron paramagnetic resonance study of carp methemoglobin. | the g anisotropy of the epr spectra of carp azidomethemoglobin is found to be ph-dependent, whereas, the spectra of human azidomethemoglobin are not. the two hemoglobins have the same g values at alkaline ph values. crystal field analysis yielded values of 2.25 and 3.31, respectively, for the rhombic distortion, v/lambda, and the tetragonal distortion, delta/lambda. the spin orbit coupling constant is lambda. at ph 4.0 the values of v/lambda and delta/lambda for carp azidomethemoglobin became 1. ... | 1977 | 190229 |
| cellular distribution of sarcoplasmic calcium-binding proteins by immunofluorescence. | specific antibodies against carp paravalbumin, crayfish calcium binding protein and crayfish arginine kinase were used for indirect immunofluorescence localization of the respective proteins. simultaneous staining of the same muscle sections with human serum containing anti-actin autoantibodies served as a probe to identify the isotropic band. parvalbumin appears to be evenly distributed in carp white muscle. the crayfish calcium binding protein however shows a distinct localization, in the isot ... | 1977 | 192701 |
| ca2+-dependent regulation of cyclic-amp phosphodiesterase by parvalbumin. | carp parvalbumin has been shown to activate rat brain phosphodiesterase in a ca2+-dependent manner. the concentration of ca2+ required for half-maximal stimulation is 1.4 x 10(-7) m, whereas rat testis ca2+-dependent regulator (cdr) of phosphodiesterase required 1.2 x 10(-6) m ca2+. the difference in the slopes of the two curves demonstrated that the activation induced by parvalbumin was not the result of a small contamination by cdr. in addition, it has been shown that ca2+ binding to parvalbum ... | 1977 | 195956 |
| [glucose-6-phosphatase activity of the pia mater of several representative vertebrates]. | studies have been made on the glucose-6-phosphatase activity in the pial matter of the lamprey lampetra fluviatilis, carp cyprinus carpio, frog rana temporaria, tortoises emys orbicularis and testudo horsfieldi, hen, rabbit and cat. the data obtained not only confirmed earlier observations on extremely high activity of the enzyme in lamprey's brain, but also demonstrated high activity of glucose-6-phosphatase in the pial matter of other vertebrates, especially in tortoises. | 1977 | 197748 |
| identification of respiratory motor neurons in the carp and determination of their firing characteristics and interconnections. | motor neurons of the respiratory muscles of the carp, located in the medulla oblongata, are identified with a signal averaging technique. analysis of the firing characteristics of these neurons provides data on their activity patterns under different circumstances. the results show that, on the one hand, the number of spikes a motor neuron fires per respiratory cycle depends on the respiratory intensity, and can even be as low as one action potential per respiration. on the other hand, with cons ... | 1977 | 200306 |
| [inhibition of corticotropic function by administration of gaba in carp (cyprinus carpio l.)]. | the intracardiac injection (50 microgram/g) of gaba to carps clearly inhibits the rise of the plasma cortisol level which occurs usually in response to the blood sampling manipulations. the inhibition starts thirty minutes after injection and lasts till the end of the experiment two hours later. the hypothesis that this neurotransmitter has a regulatory function on the corticotrop cells, especially on the excretion of acth has to be considered. | 1977 | 200377 |
| influence of quaternary structure of the globin on thermal spin equilibria in different methemoglobin derivatives. | we have measured the paramagnetic susceptibilities of sperm whale azide metmyoglobin and of carp azide, thiocyanate, and nitrite methemoglobin in the quaternary oxy (r) and deoxy (t) structures between about 300 and 90 k, using a new sensitive superconducting magnetometer. we have also measured the pressure dependence of the high- and low-spin optical absorption bands of azide metmyoglobin and of carp azide methemoglobin in the r and t structures between 1 and 2000-4000 atmospheres. at low tempe ... | 1990 | 210801 |
| ovarian neoplasia in ornamental hybrid carp (nishikigoi) in japan. | massive abdominal enlargements were observed in 21 adult carp 4--6 years old living in the breeding ponds of carp fisheries in northern japan. the abdominal enlargement rapidly increased, and the affected fish died within a few months. at necropsy, single or multiple tumors, 1.5--25 cm (average, 10.6 cm) in diameter, were found in the abdominal cavity. ovarian tissue was identified close to the tumors in 15 cases, and there was no evidence of anatomic continuity between the tumors and other visc ... | 1978 | 212993 |

| uptake, distribution, and elimination of sodium linear alkylbenzene sulfonate and sodium alkyl sulfate in carp. | uptake, distribution, and elimination of labeled surfactants, 35s-labeled sodium laurylbenzenesulfonate (35s-c12-las) and 35s-labeled sodium lauryl sulfate (35s-c12-as), were investigated in carp exposed to a low concentration level of the respective solutions found in river water in japan by whole-body autoradiography and liquid scintillation counting. whole-body autoradiograms showed that the fish absorbed 35s-c12-las and 35s-c12-as from the solutions principally through gills and that the sur ... | 1984 | 215398 |
| effects of exogenous neuraminidase on unit activity in frog spinal cord and fish optic tectum. | the effect of exogenous neuraminidase on spontaneous and evoked synaptic activity was investigated following injection of the enzyme into frog spinal cord and into cord and into the carp optic tectum. 1. injection of enzyme into spinal cord segments caused a significant increase of motoneuron activity in the corresponding spinal nerve, which lasted for 7--31 min. 2. the amplitude of postsynaptic evoked potentials in the optic tectum was increased after neuraminidase injection up to 200% of contr ... | 1979 | 215438 |
| l-aspartate: evidence for a role in cone photoreceptor synaptic transmission in the carp retina. | a number of putative neurotransmitter substances and their antagonists were applied to the carp retina while intracellular recordings from l-type cone horizontal cells were made. of all the substances tested, l-aspartate was found to be the most potent agent in depolarizing these horizontal cells in dark-adapted, partially light-adapted, and co2+-treated retinas. furthermore, dl-alpha-aminoadipate, an l-aspartate antagonist, blocked the effects of both the endogenous photoreceptor transmitter an ... | 1981 | 217017 |
| resonance raman and epr of nitrosyl human hemoglobin and chains, carp hemoglobin, and model compounds. implications for the nitrosyl heme coordination state. | we report the joint resonance raman (rr) and electron paramagnetic resonance (epr) study of five- and six-coordinate nitrosyl heme model compounds and of the titled nitrosyl hemoproteins. both epr and rr spectra fall into two types which, in the models, correspond to five- and six-coordinate nitrosyl hemes. however, neither rr nor epr spectroscopy is highly sensitive to the nature of the bond between a nitrosyl heme and a coordinated nitrogenous base, nor do the results of one technique uniforml ... | 1979 | 220232 |
| inability of parvalbumin to function as a calcium-dependent activator of cyclic nucleotide phosphodiesterase activity. | the calcium-sensitive phosphodiesterase-stimulating activity sometimes associated with parvalbumin preparations is due to contaminating (less than 0.1%) amounts of carp muscle cdr (calcium-dependent regulator)-like protein. this protein can be resolved from parvalbumins by sephadex g-75 chromatography and has many characteristics of the cdr. parvalbumin itself causes a nonspecific stimulation of phosphodiesterase at all calcium concentrations which, in the presence of cdr, can cause an apparent ... | 1982 | 220239 |

| studies on the mechanisms underlying horizontal-bipolar interaction in the carp retina. | responses of on-center bipolar cells and horizontal cells were recorded simultaneously in the carp retina, and the effect of polarization of horizontal cells on the bipolar cells was studied. hyperpolarization by extrinsic current of horizontal cells elicited in the bipolar cells a hyperpolarizing response which, unlike the electrical coupling betweeen adjacent horizontal cells, was accompanied by a change in membrane conductance. the bipolar cell responses elicited by polarization of external h ... | 1978 | 225825 |
| suppression of retinal spike discharge by dipropylacetate (depakene): a possible involvement of gaba. | effects of dipropylacetate (dpa) were studied on spike discharges in the isolated carp retina. (1) dpa, applied electrophoretically or by pressure-microinjection in the vicinity of the recording electrode at the inner plexiform layer, consistently activated spike discharges. (2) dpa introduced into the perfusate produced complex actions; some units responded to dpa with an initial activation followed by suppression of spike discharges. (3) when gamma-aminobutyric acid (gaba) was applied electrop ... | 1979 | 226226 |
