effects of ultimobranchialectomy (ubx) upon the bone catabolism and anabolism and on some aspects of the calcium metabolism regulation in anguilla anguilla l. 1976953845
[a method to measure the rate of metabolic clearance and secretion of cortisol in the eel (anguilla anguilla l.)].classical methods for the analysis of steroid dynamics were adapted to measure the metabolic clearance rate and the secretion rate of cortisol in the european eel using (1, 2-3h) cortisol as a tracer. 1. measurements were made whilst the eels were in the steady state; stresses which usually result from anaesthesia and handling were avoided by chronic catheterization of the blood vessels of the swim bladder. in this way, the plasma cortisol level were constant; thus, it was possible to obtain val ...1976953857
effects of calcitonin and ultimobranchialectomy (ubx) on calcium and bone metabolism in the eel, anguilla anguilla l.prolonged administration of synthetic salmon calcitonin (sct) to immature female silver eels, maintained in sea water, provoked a decrease of the serum calcium concentration and an increase of both the osteoblastic apposition and of the degree of mineralization of the intercellular matrix in the vertebral bone. the osteoclastic resorption and osteocytic osteolysis were not significantly affected, however the osteoclastic index was reduced. the ultimobranchial body, site of ct secretion, was caut ...19761260486
eel esophagus as an osmoregulatory organ.ion and water permeabilities were measured in the isolated esophagus of the eel (anguilla anguilla and a. japonica), and compared with those in the stomach and the intestine. the freshwater eel esophagus was impermeable both to na+ and cl- ions and to water, whereas permeabilities to the ions increased selectively after seawater adaptation. the ion permeabilities of both the freshwater and the seawater eel stomach were lower than in the seawater eel esophagus, although water permeability was gre ...19761063415
the effects of transecting the ixth and xth cranial nerves on hydromineral balance in the eel anguilla anguilla.the ixth and the xth cranial nerves in anguilla anguilla were transected, and the effects upon ion and water balance were studied in fresh water and sea water, and during transfer from fresh water and vice versa. in fresh water there is a slow demineralization due to an excess loss of na and cl ions. during freshwater to seawater transfer the eel survives only for 4-5 days. the fish do not drink and na efflux does not increase enough to extrude excess ions. in sea water the glossopharyngeal and ...1976932628
steroid biosynthesis by the ovary of the european eel, anguilla anguilla l., at the silver stage. 1976133849
the saccus vasculosus of anguilla anguilla (l.) from larva to adult. i. ultrastructural modifications of the coronet cells.the ultrastructure of coronet cells of the saccus vasculosus has been studied in specimens of anguilla anguilla (l.) at different stages of its life cycle. at all the stages observed coronet cells are composed of a basal and an apical part, the latter bearing globules with primary vesicles. in the larva (a marine form) and in the fully metamorphosed small eel at the time of entry into freshwater the narrow lumen and the vesicles within the apical globules are filled with electron-dense material. ...19761253249
trying to explain an effect of "per se" hydrostatic pressure on heart rate in fish.specific effects of "per se" hydrostatic pressure on mean heart rate have been studied on eels (anguilla anguilla l.), both untreated and treated with atropine and propranolol, and on isolated eel's heart. because temperature brings, by itself, heart rate modifications in fish, a quantitative study was performed in order to take away the increment of heart rate due to the water warming, which cannot entirely be suppressed during compression. the specific effects of "per se" pressure have been id ...19761259668
[influence of the acclimation temperature on the phospholipid metabolism of the fresh water ell (anguilla anguilla) (author's transl)].lowering of the acclimation temperature of the eel induced a reduction of 32p incorporation into the lipid phosphorus of various tissues. this effect was partly the result of a slight decrease of the inorganic phosphate exchange and metabolism of tissues. 2. the variation of the 32p incorporation into the various phosphatides was different according to the tissue ; gill and kidney phospholipids being the most effected. at high temperature (22 degrees c), the turnover of sphingomyelin and phospha ...1976933075
physiological properties of eel haemoglobin: hypoxic acclimation, phosphate effects and multiplicity.unlike the whole body oxygen affinity, which adapts readily to environmental oxygen tensions, haemoglobins, prepared from normoxic- and hypoxic-accimated eels (anguilla anguilla) show no adaptive changes in oxygenation properties or in multiplicity. hypoxic acclimation is, howeveer, accompanied by a strong decrease in red cell nucleoside triphosphates, particularly guanosine triphospphate (gtp), which depresses oxygen affinity of the composite and component haemoglobins more strongly than does t ...19765572
effect of environmental salinity change on osmotic permeability of the isolated gill of the eel, anguilla anguilla l.net water fluxes in the isolated gills of anguilla anguilla were studied during incubation in fresh water (fw) and in sea water (sw). when incubated in fw, water entry was greater in sw-adapted eels than in fw-adapted eels. in contrast, water loss in sw was less in sw-adapted eels than in fw-adapted eels. rectification of osmotic water fluxes was observed for both fw and sw-adapted eels, net water fluxes in the mucosal-serosal (m-s) direction being greater than those in the opposite (s-m) direct ...19761263144

[blood morphology of the european eel (anguilla anguilla). ii. studies on granulopoiesis].it was found that the granulocytes for anguilla anguilla mainly form in the kidney. the stem cell of granulocytes is the large hemocytoblast. sequences of development were established for the heterophil, cosinophil and basophil granulocytes. myeloblasts, promyelocytes, metamyelocytes, mature red-shaped and segmented forms were described as stages of development of the heterophil granulocytes. in the case of the eosinophil and basophil granulocytes the myeloblastic and myelocytic stages could be ...197664409
[studies on blood morphology in the european eel (anguilla anguilla). i. erythrocytes and their developmental stages].by means of heart tapping we produced a larger loss of blood in the european eel, anguilla anguilla. this resulted in enriching the peripheric blood with erythroblasts and proerythrocytes. by panoptic staining erythroblasts, proerythrocytes and mature erythrocytes could be prepared and described. by the aid of supravital staining it was possible to detect mitochondria and substantia granulofilamentosa in all stages of development. phase contrast observations proved that the erythrocytes of angui ...197661916
[feeding and growth of elvers of anguilla anguilla l. (eel-like teleosten fish) experimentally reared at various temperatures in the laboratory].in france, there are few researches carried out on the eel's elvers rearing. so, we have undertaken to do, in a first time, a study of their alimentation and growth, in relation to the temperature, at laboratory. the structure of european eels' elvers population, drawn in its natural environment, shows a polymodal frequency distribution of individual weights. the temperature has a direct effect on general metabolism of animals and consequently on their growth. for temperatures included between 1 ...197613699

[demonstration of leucine aminopeptidase in the peritoneal epithelium of early post-larval stages of anguilla anguilla l.)].the coelom of elvers (anguilla anguilla l.), eel0, is contenting glycoproteids, but these are not improvable in following stages of development. in peritoneal epithelium of eel0 activity of leucinamino-peptidase is present, but absent in the stage 2a. we can suppose that glycoproteids vanish by enzymatic catabolism and resorption within the peritoneal epithelium.19751213251
[comparative metabolism of phospholipids of osmoregulation effector organs in european eel (anguilla anguilla)].the phospholipid composition from various organs of the fresh water eel, such as gill, kidney, gut, liver and muscle, were determined by thin-layer chromatography. the major phosphatides found in these tissues were pc, pe and sph and minor constituents ps, pi, dpg, ap and also lpc in the gut. a greater percentage of ps and sph occurs in the osmoregulatory effector organs such as gill, kidney, and gut. from in vivo comparative kinetic studies of the 32p incorporation into the phospholipids, betwe ...19751182217
[histological, histochemical and histophysiological changes of the exocrine pancreas and stomach fundus in anguilla anguilla l. in the course of postlarval development].during the postlarval development of eels exocrine status of pancreas and fundus was investigated. therefore results of histomorphological, histophysiological and histochemical tests were interpreted. the conclusion is that there is no secretory activity till stage i. no relation exists between secretory activity and food-supply.19751158098
catecholamine fluorescence in the pituitary of the eel, anguilla anguilla, with special reference to its variation during background adaptation.in the neuro-intermediate lobe (nil) of the eel, anguilla anguilla, a specific formaldehyde-induced fluorescence, indicating a catecholamine (ca) innervation, has been demonstrated in the neural lobe processes. microspectrofluorimetric analyses and pharmacological treatments indicate noradrenaline or dopamine or both to be responsible for the fluorescence. the fluorescence in the nil has displayed a definite tendency toward variation during the adaptation to a white and to a black background. th ...19751122533
