| homeothermic fish and hemoglobin: primary structure of the hemoglobin from bluefin tuna (thunnus thynnus, scromboidei). | some fish are warm-bodied, e.g. the bluefin tuna (thunnus thynnus), which has a muscle temperature 12-17 degrees c higher than its environment. this endothermy is achieved by aerobic metabolism and conserved by means of a heat-exchanger system. the hemoglobins of bluefin tuna are adapted to these conditions by their endothermic oxygenation, thus contributing to the preservation of the body energy. this is a new and so far unique property of tuna hemoglobin. the primary structure of the alpha and ... | 1987 | 3620111 |
| intrinsic fluorescence of carp hemoglobin: a study of the r----t transition. | the intrinsic fluorescence of hemoglobins is known to respond to ligand-induced changes in the quaternary structure of the protein. carp hemoglobin is an interesting model to study the quaternary transition since its r----t equilibrium is ph-dependent and at low ph, in the presence of organic phosphate, it remains in the t or 'deoxy' quaternary structure, even when saturated with ligand. in this study, using front-face fluorometry, we show that the intrinsic fluorescence intensity exhibited by c ... | 1987 | 3620472 |
| the influence of environmental temperature on the lymphocyte populations in carp (cyprinus carpio l.). | the influence of environmental temperature upon the lymphocyte populations in carp (cyprinus carpio l.) has been studied by immunoperoxidase labeling using different antisera. in carps kept in a warm and a cool environment, respectively, rabbit anti-carp igm as well as rabbit anti-carp fc antiserum showed different percentages of ig-positive lymphocytes, whereas the percentage remained unaffected by temperature after the use of rabbit anti-carp fab antiserum with a specificity against l-chains. ... | 1987 | 3555478 |
| ultrastructural characterization of leucocytes in the pronephros of carp (cyprinus carpio, l.). | in the pronephros of carp (cyprinus carpio, l.) the following cells were found and ultrastructurally characterized: erythrocytes; lymphocytes and plasma cells; thrombocytes; neutrophilic, eosinophilic and basophilic granulocytes; phagocytic reticular cells and monocytes and non-phagocytic reticular cells. the cells could be separated on a percoll continuous density gradient and relatively pure fractions could be obtained. in vitro phagocytosis of bacteria (bacillus megaterium) was found in monoc ... | 1987 | 3109968 |
| increased gonadotropin levels in goldfish do not result in alterations in circulating thyroid hormone levels. | to determine whether increases in gonadotropin levels are capable of altering thyroid function in goldfish, plasma thyroid hormone levels were measured following induced changes in endogenous gonadotropin secretion and injection of carp gonadotropin. radio-frequency lesions placed in the nucleus preopticus periventricularis or monosodium-l-glutamate-induced lesions of the posterior nucleus lateralis tuberis (nlt) of the hypothalamus were capable of stimulating significant increases in plasma gon ... | 1987 | 3114043 |
| experimental verification of the effect of the form (scaly or scaleless) of carp host (c. carpio l.) on the growth rate of micropopulations of gyrodactylus katharineri malmberg, 1964 (monogenea). | it was demonstrated that the growth rate of gyrodactylus katharineri micropopulations parasitizing the fry of cyprinus carpio l. was effected by water temperature and by the form of the fish host (scaly or scaleless). at lower water temperature (12 degrees c) the number of parasites increased in both host forms approximately at the same intensity. in warmer water (18 degrees c), the parasites reproduced intensively only on the scaly form of fish, whereas no parasites were found on the scaleless ... | 1987 | 3428761 |
| interaction of mycoplasma mobile 163k with erythrocytes. | mycoplasma (m.) mobile 163k isolated from fish was investigated for its hemadsorbing, hemagglutinating, and hemolysing capacities and for its ability to adhere to erythrocytes. hemadsorption to the colonies of m. mobile occurred with ovine, bovine, equine, trout, and carp erythrocytes and was inhibited by treatment of the mycoplasmas with substances acting on proteins (pronase, trypsin, glutaraldehyde), heat, uv-irradiation and homologous antiserum. hemadsorption could be prevented also by treat ... | 1987 | 3439386 |
| environmental changes induced by growth-associated triggering factors in injured optic nerve of adult rabbit. | central nervous system (cns) neurons of mammals regenerate poorly after axonal injury. however, if an injured cns neuron (rabbit optic nerve) is supplied with appropriate soluble substances ("growth-associated triggering factors") derived from medium conditioned by regenerating fish optic nerve or newborn rabbit optic nerve, it can express regeneration-associated characteristics. such characteristics include a general increase in protein synthesis, changes in synthesis of specific polypeptides, ... | 1987 | 3470808 |
| immune response of carps (cyprinus carpio l.) against dextran. | in carps no antibodies could be evoked by immunization with soluble high molecular weight dextran using doses of 1-5000 mg dextran per kg body weight. on the other hand, an immune response against dextran could be elicited by immunization with a vaccine of leuconostoc mesenteroides b512 as well as a dextran-bsa-conjugate. these carp anti-dextran antibodies showed precipitating and agglutinating activities with specificity against alpha linked dextran determined by the almost complete inhibition ... | 1987 | 2439389 |
| mechanism of the interaction between myelin basic protein and the myelin membrane; the role of arginine methylation. | the addition of solutions of bovine myelin basic protein to suspensions of unilamellar vesicles prepared from whole myelin suspensions results in the rapid equilibrium association of the vesicles into dimers, followed by time-dependent aggregation reactions. other cationic proteins also induce the dimerization of the vesicles and equilibrium constants for dimer formation are obtained for bovine myelin basic protein, lysozyme, polyhistidine and myelin basic protein from carp, which differs from t ... | 1987 | 2440426 |
