biochemical compartmentation of fish tissues vii non-specific phosphomonoesterases in vital organs.	the viscera were compartmentalised in relation to non-specific phosphomonoesterase in a major carp, a catfish and a murrel. activity was highest in the middle region of the kidney and lowest in the cephalic region of muscle. the observed variations in various regions of the viscera are discussed in relation to feeding habits, growth rate and biochemical make-up of the viscera.	1985	4013773
quaternary structure has little influence on spin states in mixed-spin human methemoglobins.	a key feature of the perutz stereochemical model for cooperativity in hemoglobin is a strong coupling between quaternary structure and the spin state of the heme iron [perutz, m. f. (1979) annu. rev. biochem. 48, 327-386]. while this coupling appears to be present for carp azide methemoglobin, it should also be present for all liganded forms of human methemoglobin that exhibit a thermal high-spin in equilibrium low-spin equilibrium. to test this hypothesis, we have measured the changes in spin e ...	1985	4016083
occurrence of n-acylethanolamine phospholipids in fish brain and spinal cord.	n-acylethanolamine phospholipids were identified in the central nervous system of the fresh water fish, pike (esox lucius) and carp (cyprinus carpio), at levels ranging from 0.1 to 0.9% of total phospholipid. the n-acylethanolamine phospholipids of carp brain were isolated and characterized by chemical, biochemical and spectroscopic methods. two major species, 1,2-diacyl-sn-glycero-3-phospho(n-acyl)ethanolamines (approx. 30%) and 1-o-(1'-alkenyl)-2-acyl-sn-glycero-3-phospho(n-acyl)ethanolamines ...	1985	4016139
kinetic differences at low temperatures between r and t state carbon monoxide-carp hemoglobin.	we use the low-temperature recombination kinetics of carbon monoxide with carp hemoglobin to determine that the r and t states of hemoglobin exhibit different low-temperature geminate recombination kinetics. the peak of the fitted gaussian activation energy spectrum is at 1.5 kcal/mol for r state and 1.8 kcal/mol for t state. the distribution in activation energies is fit well by the agmon-hopfield linear strain model. the t state is fit with a stronger elastic constant than r, and has a larger ...	1985	4016198
[electrical characteristics of the epithelial tissue and cells of the carp and frog gallbladder].	transepithelial potential and resistance, the ratio of resistance of the apical to the basal cell membranes (ra/rb) were studied during transmural current clamps in isolated frog and fish gall-bladder (gb) with ringer's solution on both sides. the findings show that: 1) the difference between the mucosal and serosal membrane potentials (mps) was 3-8 mv as determined by transmural potential; 2) the ratio ra/rb depends on the mp value: it was less than 1 if mp was about 30 mv, and more than 1 if m ...	1985	4018298
antibody diversity in fish. isoelectrofocalisation study of individually-purified specific antibodies in three teleost fish species: tench, carp and goldfish.	natural anti-dnp antibodies were isolated by affinity chromatography from individual sera of three cyprinid fish species (carp, goldfish and tench) and their electrofocusing (ief) spectra were analysed in reducing conditions. in addition, immune anti-penicillin and anti-bsa antibodies were isolated from individual and pooled tench sera, and studied by ief techniques on reduced samples. diversity rates appeared to be rather low in the three fish species, and striking similarities arose between in ...	1985	4018343

a comparative study of tropomyosin from vertebrate ventricles.	a comparative study of vertebrate ventricle tropomyosin has been carried out from the viewpoint of molecular evolution. the ventricles containing one-component tropomyosin were generally known, and in this paper those containing two components were also found in 8 species among mammals, reptiles, amphibia, and fish, but not among birds. the two components were concluded to be authentic tropomyosin and not artifacts since they showed lower electrophoretic mobilities in the presence of urea, and t ...	1985	4030730
responsiveness and receptive field size of carp horizontal cells are reduced by prolonged darkness and dopamine.	in the fish retina the interplexiform cells contain dopamine and provide a centrifugal pathway from the inner plexiform layer to horizontal cells of the outer plexiform layer. dopamine application reduced the responsiveness and receptive field size of cone horizontal cells, as did a prolonged period of complete darkness. other results suggest that the interplexiform cells may release dopamine after a prolonged period in the dark. the interplexiform-horizontal cell system may modify the strength ...	1985	4035351
effect of thiol-reactive reagents on the permeability of fish erythrocyte membrane for spin-labelled non-electrolytes.	carp erythrocytes were treated with p-chloromercuribenzoate or n-ethylmaleimide. it was observed that these thiol-group inhibitors decreased the transport of spin-labelled hydrophilic compound, 4-hydroxy-2,2,6,6-tetramethylpiperidine-1-oxyl, and increased the transport rate of more hydrophobic 2,2,6,6-tetramethylpiperidine-1-oxyl.	1985	4036446
temperature dependence of the dielectric properties of blood.	the aim of the work was to investigate the temperature effect in physiological range on the dielectric properties of a fish (cyprinus carpio) blood. by applying an empirical non-damaging method and statistical analysis of the dielectric data, it is observed that a heating of carp blood induces an almost linear value variation of the electrical conductivity and permittivity of the intracellular matter of carp red blood cells. the dielectric data, however, reveal anomalous behaviour for conductivi ...	1985	4043438
light and electron microscopic identification of gonadotrophic cells in the pituitary gland of the goldfish by means of immunocytochemistry.	immunocytochemical techniques were used at the light and electron microscopical levels in order to localize and to characterize the gonadotrophs in the goldfish pituitary gland by means of antibodies to carp gonadotrophin (c-gth) or its subunit (c-gth beta). at the light microscopical level antibodies to c-gth reacted weakly with cells located in the rostral pars distalis (rpd) and strongly with cells of the proximal pars distalis (ppd). the labeling was restricted to the proximal pars distalis ...	1985	4043726
electrophysiological measurements of the spectral sensitivity of three types of cones in the carp retina.	the spectral sensitivities of red-, green-, and blue-sensitive cones were measured by intracellular recording in the carp retina. the responses from all cones were univariant, i.e., the waveform of a response to any wavelength and at any intensity could be superimposed on the response to other wavelengths if the intensity was properly selected. red-sensitive cones showed a maximum sensitivity at about 620 nm, green-sensitive cones at about 520 nm, and blue-sensitive cones at about 460 nm. the pe ...	2014	4046238
