| [histological study of the teleost liver. iii. the system of biliary pathways]. | in the liver of haplochromis burtoni four divisions of the intrahepatic biliary pathways can be distinguished: canaliculus, canaliculus ductulus transition, ductulus biliferus, ductus biliferus. there are no transitional stages between the hepatocytes and biliary epithelial cells. the results of the investigation suggest that the ductules open into the ducts in two ways, directly and by graded transition of structure. the first part of the ductulus has a very narrow lumen and therefore is simila ... | 1979 | 232800 |

| ultrastructural demonstration of hormone-induced movement of carotenoid droplets and endoplasmic reticulum in xanthophores of the goldfish, carassius auratus l. | the hormone-induced pigment dispersion in primary cultures of xanthophores of goldfish (carassius auratus l.) has been shown to involve the dispersion of not only carotenoid droplets but also of smooth endoplasmic reticulum. the dispersion of these organelles is inhibited by cytochalasin b and is accompanied by thinning of the cell body, thickening of the processes, and also overall changes in cellular morphology (process extension) under certain conditions. electron microscopic examination of h ... | 1978 | 210950 |

| hormone-stimulated glycogenolysis in isolated goldfish hepatocytes. | hepatocytes isolated from the liver of the common goldfish carassius auratus l. with crude bacterial collagenase maintained atp levels for at least 2 h. glycogenolysis was maximally activated by 1 x 10(-6) m epinephrine and 5.8 x 10(-9) m glucagon. in liver cells incubated in calcium-free buffer containing 1 mm ethylene glycol-bis-(beta-aminoethylether)-n,n'-tetraacetic acid, basal glycogenolysis was enhanced by the addition of 1-4 mm calcium but the elevation of cyclic amp and glycogenolysis du ... | 1976 | 183509 |
| in vitro induction of tyrosinase activity in goldfish (carassius auratus l.) integument by acth and dibutyryl-camp. | tyrosinase was first detected in melanoblasts by the dopa-oxidase reaction in the presence of catalase in explants of goldfish integument after 12 hr culture with either acth (1iu/ml) or db-camp (0.1mm). melanin did not appear in the new melanocytes until 24 hr. the data indicate that the release of camp within the melanoblast in response to acth treatment is rapid and the tyrosinase in the melanoblast is released from inhibition and/or activated at least 12 hr prior to melanization of premelano ... | 1976 | 175039 |
| 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 |
| [effect of acetylcholine on the heart ventricle of the goldfish carassius auratus, teleosts, cyprinidae. modification of the response as a function of temperature]. | acetylcholine (ach) is more efficient on the red fish heart at 14 degrees c than at 5 degrees c or 8 degrees c. it does not probably exist a cholinesterasic system and high concentrations of ach are to be used to obtain significant variations of the heart frequency. ach does not appear as a physiological mediator and temperature seems to be an essential factor in heart regulation and modulation of the pharmacological effects of eventual mediators. a thermal adaptation exists but the fast increas ... | 1978 | 150903 |
| comparative activities of glycogen phosphorylase and gamma-amylase in livers of carp (cyprinus carpio) and goldfish (carassius auratus). | 1. the activity of glycogen phosphorylase in goldfish liver is fivefold greater than that in carp liver, suggesting that the enzyme may not be as important in regulating glycogenolysis in the latter species. 2. the activity of gamma-amylase is comparable in carp and goldfish liver. 3. the activity of hepatic gamma-amylase is approximately one-half that of glycogen phosphorylase in carp whereas in goldfish, the activity of gamma-amylase is less than one-sixth that of phosphorylase. hepatic gamma- ... | 2002 | 122584 |
| studies on the biology of fish bone. iii. ultrastructure of osteogenesis and resorption in osteocytic (cellular) and anosteocytic (acellular) bones. | the comparative ultrastructure of fish bone osteogenesis and resorption induced by scale removal was described in the osteocytic (cellular-boned) carassius auratus and the anosteocytic (acellular-boned) tilapia macrocephala. osteocytes, present in osteocytic bone, were lacking in anosteocytic bone. in osteocytic bone the osteoblast secreted a collagenous preosseous matrix in which it became enmeshed and then was termed a preosteocyte. when the preosseous matrix mineralized, the preosteocyte was ... | 1979 | 115551 |
| temperature-related changes in the erythrocytic carbonic anhydrase (acetazolamide-sensitive esterase) activity of goldfish, carassius auratus. | 1. carbonic anhydrase activity in 'membrane' and 'cytosol' fractions of goldfish erythrocytes was assayed by the p-nitrophenyl acetate procedure following thermal acclimation. 2. the thermal sensitivity of "membrane"-associated activity was apparently unaltered by acclimation. "cytosol" activity in warm-acclimated specimens was somewhat more thermosensitive than that animals maintained at low temperature. 3. significant increases in specific activity, and activity per unit volume of packed cells ... | 1998 | 108353 |
| [immunocytology of alpha-endorphin positive hypothalamic fibers of carassius auratus l. and cyprinus carpio l]. | an immunocytological study of the basal hypothalamus of carassius auratus and cyprinus carpio with an alpha-endorphin antiserum shows the different nerve processes belonging probably to the immunoreactive cells of the lateral part of the n.l.t. according to their pathways, two main fibre tracts have been distinguished: many fluorescent fibres converge towards the pituitary gland into which they enter, other fibres run caudally through the tuber towards the nucleus tuberis inferior (baumgarten an ... | 1999 | 97002 |
| neuron culture from adult goldfish. | neurons and glia from the central nervous system of the adult teleost carassius auratus have been grown as explant cultures of minced brain tissue and as trypsin dissociated cells. these cultures exhibit extensive neurite growth from two neuronal types, have organotypic ultrastructure, and contain electrically active cells. autoradiographic data indicate that these neurons do not divide in culture, and histological evidence suggests that some mature neurons survive explantation and regenerate pr ... | 1976 | 63541 |
| [immunocytological study of corticotropic cells in several species of teleost fish: gasterosteus aculeatus l., carassius auratus l., lebistes reticulatus p., salmo irideus gibbs and perca fluviatilis l]. | 1976 | 59678 | |
| [on the effect of some inhibitors of proteinbiosynthesis on activity and learning behavior of goldfish (carassius auratus auratus l)]. | concerning the problems of learning and memory there is a distinction of a short term memory (stm) and a long term memory (ltm). it is supposed that the stm is an electrical phenomenon, whereas the ltm depends on material changes. the assumed materials are rna, proteins, lipids, amines etc, and the primary carrier of the information is dna. but there is a discrepancy: learning-specificity is based on environmental changes, but not the structure of dna. for the investigation of this, we trained g ... | 1975 | 53965 |

| a cl-/hco-3-atpase in the gills of carassius auratus. its inhibition by thiocyanate. | an atpase is demonstrated in plasma membrane fractions of goldfish gills. this enzyme is stimulated by cl- and hco-3, inhibited by scn-. biochemical characterization shows that hco-3 stimulation (km = 2.5 mequiv./l) is specifically inhibited in a competitive fashion by scn- (ki = 0.25 mequiv./l). this residual mg2+-dependent activity is weakly affected by scn-. in the microsomal fraction chloride stimulation of the enzyme occurs in the presence of hco-3 (km for chloride = 1 mequiv/l); no stimula ... | 1977 | 18177 |

| modulation of the root effect in goldfish by atp and gtp. | both atp and gtp are present in considerable amounts in red cells of the common goldfish carassius auratus. they both influence the root effect of the single major fish hemoglobin, but gtp is, depending on ph, 2-6 times more effective than atp. the two triphosphates account for 3/4 of the effect of trichloroacetic acid supernatant obtained from hemolysate which contains still some compound(s) which can influence the shift of the root effect toward higher ph. | 1977 | 13864 |
