| [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 |
| 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 |
| [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 |
| 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 |
| 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 |
| 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 |
| 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 |
| 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 |
| 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 |
| 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 |
| 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 |
| 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 |
| [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 |
| 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 |

| another case of human gnathostomiasis in indonesia. | a male gnathostoma spinigerum was removed from the abdominal wall of a 29-year-old woman, who was in the habit of eating "naniura", a dish containing raw carp (cyprinus carpio). after the removal of the worm she still had pain in her chest and noticed intermittent swelling of her right lower arm. probably the patient still had one or more gnathostoma worms migrating in her body. | 1978 | 155313 |
| two calcium regulation systems in squid (ommastrephes sloani pacificus) muscle. preparation of calcium-sensitive myosin and troponin-tropomyosin. | the ca-regulatory system in squid mantle muscle was studied. the findings were as follows. (a) squid mantle myosin b (squid myosin b) was ca-sensitive, and its ca-sensitivity was unaffected by addition of a large amount of rabbit skeletal myosin (skeletal myosin) or rabbit skeletal f-actin (skeletal f-actin). (b) squid myosin was prepared from the mantle muscle. it showed a heavy chain component and two light chain components in the sds-gel electrophoretic pattern: the molecular weights of the l ... | 1978 | 153902 |
| calcium sensitivity of mantle muscle of squid. | ca2+-sensitivity of squid muscle proteins was studied by competition tests between squid actin and carp myosin on squid myosin b and by cross combination tests between squid myosin and actin and between carp myosin and squid thin filament fraction. the results suggest that the regulatory system of the squid mantle muscle is actin-linked as in skeletal muscle rather than myosin-linked. this view is supported by the presence of troponin-like components on sds-disc electrophoresis of squid thin fil ... | 1978 | 149115 |
