| effects of exogenous neuraminidase on unit activity in frog spinal cord and fish optic tectum. | the effect of exogenous neuraminidase on spontaneous and evoked synaptic activity was investigated following injection of the enzyme into frog spinal cord and into cord and into the carp optic tectum. 1. injection of enzyme into spinal cord segments caused a significant increase of motoneuron activity in the corresponding spinal nerve, which lasted for 7--31 min. 2. the amplitude of postsynaptic evoked potentials in the optic tectum was increased after neuraminidase injection up to 200% of contr ... | 1979 | 215438 |
| hydrolysis and synthesis of wax esters by different systems of carp hepatopancreas preparation. | it was found that the supernatant of hepatopancreas homogenate of the carp, cyprinus carpio, contained enzymes involved in the hydrolysis and esterification of wax esters. the enzymes were salted out by 30% saturation with ammonium sulfate. this fraction also contained the highest activities of lipase and esterase. the enzyme for the hydrolysis of wax esters, together with lipase and esterase, was eluted in tube numbers 20 to 22 (void volume) from a sephadex g-200 column. on the other hand, the ... | 1979 | 762038 |
| the hematology of mrigal, cirrhina mrigala (ham.) (teleostei: cyprinidae). | hematological parameters of a carp, cirrhina mrigala, are reported here. haematocrit ranged from 29.0 to 44.0%. the range of hemoglobin was 7.06 to 11.86 g/100 ml of blood, and the total number of erythrocytes varied from 1.7 to 3.0 million/mm3 of the blood, both hemoglobin and erythrocyte concentrations being higher in males than in the females. mean esr was 1.88 mm/h, with higher esr in females (2.05 mm/h) than in the males (1.67 mm/h). the clotting time in males (41.0 seconds) was lower than ... | 1979 | 543563 |
| the surface connected canalicular system of carp (cyprinus carpio) thrombocytes: its fine structure and three-dimensional architecture. | the presence and the three dimensional distribution of the surface connected canalicular system (sccs) in thrombocytes of a teleost, cyprinus carpio, were studied using a transmission electron microscope, a high voltage electron microscope and a scanning electron microscope. when the specimens were fixed routinely in glutaraldehyde followed by osmium tetroxide, numerous electron lucent vesicles and canaliculi were distributed throughout the cytoplasm. as ruthenium red-positive reaction product w ... | 1979 | 519726 |
| calcium and magnesium binding by parvalbumin. a proton magnetic resonance spectral study. | proton magnetic resonance spectroscopy has been used to monitor the kinetics and nature of the conformational transitions induced by binding of calcium and magnesium to carp parvalbumin. rate constants have been determined for the exchange between the cation dependent conformational states of the protein in solution. these data enable a description of the kinetics and mechanism controlling the calcium flux in vivo during contraction. | 1979 | 518923 |

| horizontal cells of the carp retina: golgi impregnation and procion-yellow injection. | application of two methods for the selective staining of neurons, golgi impregnation and intracellular marking with procion yellow, has revealed the anatomical arrangements of the horizontal cells in the carp retina. there are two basic horizontal-cell types, those with axons and these without. the former can be subdivided into three groups on the basis of the pattern of branching of the dendrites. these three structural groups are also functionally distinct, as shown by the electrical recording ... | 1978 | 83194 |
| synchronized rhythmic discharges of the secondary olfactory neurons in carp. | (1) rhythmic and synchronized multiunit bursts of spike discharges, which were superimposed on the peaks of the oscillatory potentials of 4--10 hz (olfactory tract waves), were induced in the olfactory tract fibers of the carp in response to olfactory stimulation. suppression of the spike discharges was observed during the interburst periods of discharges. (2) single-unit analysis revealed three types of discharge patterns in the olfactory tract fibers in response to olfactory stimulation: rhyth ... | 1978 | 709369 |

| receptive field arrangement of color-opponent bipolar and amacrine cells in the carp retina. | seven color-opponent bipolar and 50 color-opponent amacrine cells were identified in the carp retina and their spectral responses examined by using procion-dye-filled micropipets for staining and recording. four of the bipolar cells had a +r-g-and three a +y-b-type chromatic center. six of the bipolar cells showed hyperpolarizing non-color-opponent surrounds, while one +r-g-type cell had a +y-rb-type surround. this cell showed the greatest complexity of all bipolar cells identified so far, and i ... | 1978 | 755292 |
| ionic mechanisms underlying the center and surround responses of on-center bipolar cells in the carp retina. | reversal potentials were measured for the center and surround responses of on-center bipolar cells in the carp retina. in the scotopic condition, the center response showed a reversal at 29 +/- 13mv, the surround response at 38 +/- 13 mv. the result suggests that both the center and surround responses were -53 +/- 11 mv and -59 +/- 11 mv, respectively. these responses were sensitive to the red light. it is therefore suggested that both the center and surround responses contributed by rods are me ... | 1978 | 755291 |
| effects of gaba on neuronal activities in the distal retina of the carp. | when a transient depolarization was evoked in horizontal cells by a transretinal current pulse, a small hyperpolarizing deflection (probably ipsp) was detected in cones. the ipsp was abolished by superfusion of the retina with gaba-containing ringer solution, which also hyperpolarized the cones. these results suggest that, in the dark, a gaba-mediated negative feedback was operating from horizontal cells to cones, and terminated in the light. application of gaba also caused remarkable changes in ... | 1978 | 755289 |
| electrically evoked responses (e-responses) of l-and c-type horizontal cells in the carp retina. | electrically evoked responses (e-responses) of l-and c-type horizontal cells produced by transretinal stimulation were studied under chromatic illumination in the carp retina. from the examination of e-s relations (e-response verus s-potential) and of the shape of both responses the following results were obtained: (1) equilibrium potential of subsynaptic membrane is estimated as 0 to 10 mv above zero membrane potential. (2) l-cells receive signals from red-and probably from green-sensitive cone ... | 1978 | 755288 |
| [on--off impulse activity of carp retina amacrine cells]. | properties of spontaneous and light-evoked spikes of the "on--off" amacrine cells of the carp retina were studied. it was assumed that the dendrites of amacrine cells generated spike potentials and conducted them to the cell body. the data obtained suggest that the dendrites of amacrine cells have many spike-generation zones and that the transient depolarization component of the amacrine response to light is the compound spike consisting of many separate spikes generated in different parts of th ... | 1978 | 744273 |
| gas exchange in the carp gills in normoxic and hypoxic conditions. | respiratory exchange measurements in a teleost fish, cyprinus carpio, in normoxic and hypoxic conditions are presented. oxygen pressure in the dorsal aortic blood in normoxic carp was much lower than that in most of teleosts and elasmobranchs in similar conditions. the most evident physiological adjustment to the hypoxic condition was the increased ventilation due to an increased frequency of operation of the branchial pump. increased perfusion at the gills played a small role in the physiologic ... | 1978 | 741107 |
| studies on the mechanisms underlying horizontal-bipolar interaction in the carp retina. | responses of on-center bipolar cells and horizontal cells were recorded simultaneously in the carp retina, and the effect of polarization of horizontal cells on the bipolar cells was studied. hyperpolarization by extrinsic current of horizontal cells elicited in the bipolar cells a hyperpolarizing response which, unlike the electrical coupling betweeen adjacent horizontal cells, was accompanied by a change in membrane conductance. the bipolar cell responses elicited by polarization of external h ... | 1978 | 225825 |
| abnormality in body curvature of cyprinus carpio after injection of anaesthetics. | abnormalities in the body curvatures were noticed in cyprinus carpio after the injection of anaesthetics, viz. paraldehyde, tertiary butyl alcohol and butanol. these abnormalities occurred behind the dorsal fin and progressively developed over a period of four months. the abnormalities affect the locomotion and speed of swimming of the fish and appear to be due to toxic effects of the anaesthetics. | 1978 | 742410 |
| [interrelationships of the neurosecretory cells and capillaries in the preoptic nucleus of the carp]. | three layers are tentatively recognized in the wall of a blood capillary of nucleus praeopticus (np) of the carp, cyprinus carpio l: the inner layer--endothelium, the middle layer--basement membrane with pericytes, and the outer broken layer containing mostly leucocytes and fibroblast-like cells. 1). the plasmalemma of the neurosecretory cells (nsc) makes a direct contact with a capillary: (a) with the plasmalemma of a sole-like process of the endothelial cell (0.1%), (b) with the basement membr ... | 1978 | 734769 |
| occurrence of catecholamine-containing specific granules in the venous endothelia of carp. | the formaldehyde-induced fluorescence technique and the argentaffin reaction with ultra-thin sections were applied to the vessels of carp to demonstrate the presence of a catecholamine. after formaldehyde gas treatment for 30 minutes at 50 degrees c, the venous endothelia emitted a greenish-yellow fluorescence suggesting the presence of a primary catecholamine. in the endothelial cells of veins, the specific granules, consisting predominantly of spherical granules with a diameter of about 0.3 mi ... | 1978 | 707309 |
