| 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 ... | 1975 | 1122533 |
| 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 ... | 1976 | 1063415 |
| [electroencephalographic activity of a fish (anguilla anguilla l.) exposed to various hyperbaric conditions (author's transl)]. | 1. as a continuation of previous work where our methods were fully described (barthelemy et al., j. physiol., paris, 1975, 70, 173-183), the present paper consists of research on eeg activity modifications in the eel (anguilla anguilla l.) submitted to different hyperbaric conditions (fig. 1). 2. in contrast with mammals, the fish makes it possible to isolate the specific effects of per se pressure: those were researched to a maximum pressure of 101 ata. slow and sharp-pointed theta waves appear ... | 1976 | 1011173 |

| [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 ... | 1976 | 933075 |
| 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 ... | 1976 | 932628 |
| relative estimation of ventilatory fow rate in the eel (anguilla anguilla l.) | freshwater eels (anguilla anguilla l.) were experimented on in order to measure ventilatory flow rate (by means of a direct method of collecting expired water), and simultaneously, to record sub-opercular pressure changes and opercular displacements (operculogram). significant correlations (p less than 0.01) were found between the ventilatory flow rate (v) and various characteristics of operculiogram records. the relationships which are significant in each fish experimented on are; v = a(f.lo) + ... | 1977 | 928851 |

| high affinity calcium binding peptides from the gills, gut and kidneys of the freshwater eel (anguilla anguilla). | we report the isolation of high affinity calcium-binding peptides from homogenates of gills, gut and kidneys of the freshwater eel anguilla anguilla. these peptides show identical gel-filtration profiles on biogel p-6, from which a molecular weight of 3500 was estimated. the average binding constant (kf) for calcium is 7 . 10(7)m-1, and mgcl2 up to 5 mm does not displace calcium. | 1978 | 708780 |
| growth of striated muscle fibres in the m. lateralis of the european eel anguilla anguilla (l.) (pisces, teleostei). | diameters of red and white muscle fibres were measured in the m. lateralis of eels cultured under laboratory circumstances over a period of 2 years, starting from the glass eel stage. the red fibres of eels less than 10 cm are unique in that their growth involves increase in diameter only. growth of the red fibres in eels greater than 10 cm, and of the white fibres in eels at all lengths considered, is characterized by an increase in number as well as diameter, the relative importance of these t ... | 1978 | 640952 |
| neurohypophysial hormonal control of kidney function in the furopean eel (anguilla anguilla l.) adapted to sea-water or fresh water. | low doses of arginine-vasotocin (avt), isotocin and oxytocin (1 pg-1 ng/kg body weight) were antidiuretic in eels adapted to fresh water but not in those adapted to sea-water. high doses (more than 10 ng/kg) were always diuretic. no effects on tubular water reabsorption were observed and the glomerular filtration rate (gfr) was proportional to the maximum reabsorptive rate for glucose (tm(glucose)) in eels adapted to sea-water. increases in urinary flow appeared therefore to result from glomerul ... | 1978 | 627824 |
| [electrical activity of the brain of the eel (anguilla anguilla l.) subjected to hypoxia and hypercapnia]. | the effects of hypoxia and hypercapnia on the electric activity of cerebral vesicles have been studied in 48 unrestrained eels placed in water in a soundproof location. 1. hypoxia (pwo2 less than 5 torr) was well endured for 8 hours after which sharp bursts appeared, rapidly followed by cerebral death. 2. hypercapnia (pwco2 congruent to 14 torr) gave an amplitude decrease in cerebral activity beginning with the first hour, and after 8 hours there was an appearance of slow waves which progressive ... | 1977 | 615248 |
