A new stable human hypernephroma cell line has been characterized by differential staining R-, C- and Ag-I-techniques. The karyotype of the cultivated hypernephroma cells has been designed using the statistical analysis and karyotype reconstruction methods. The specific chromosomal markers of the cell line are described. 相似文献

Effect of various doses of low-tense laser irradiation on proliferative and functional morphology of fundal gastric epitheliocytes in rats was studied by endogastric irradiation with the methods of histochemistry, autoradiography, transmission and scanning electron microscopy. It was shown that laser irradiation effect varied with its dose and was spread on gastric mucosa lying at the site of direct influence. The doses of irradiation that had no alternative effect induced reconstruction of epitheliocytes especially mucocytes indicating intensification of specific function in them, as well as an increase of proliferative activity. 相似文献

Binding of auramine O to poly-(methacrylic acid) (PMA) has been established over a large range of C0p/C0d values using spectroscopic methods (UV absorption and visible fluorescence emission spectra), equilibrium and sedimentation dialysis, potentiometric and viscosimetric titrations. All the results show qualitative agreement with those obtained previously with the system crystal violet-PMA although the binding seems to be less strong for auramine O than for crystal violet. From dialysis experiments binding isotherms were obtained at three different degrees of neutralization α'; at α' = 0.10 the results could be fitted to a Langmuir isotherm but at α' equal to 0.40 and 0.65 deviations with respect to such an isotherm occur. The results of potentiometric and viscosimetric titrations confirm that the conformational transition which the dye-free PMA exhibits upon ionization is affected by the dye binding. The region in which the conformational transion occurs is broadened and is less sharply defined in the presence of auramine O. 相似文献

The interferon-specific cellular receptors in human cells cultures differing in sensitivity to alpha-interferon have been studied. The J-41 cells resistant to alpha-interferon are practically devoid of receptors highly specific to alpha-interferon. The coefficient of equilibrium and the number of receptors analyzed after Scatchard for J-96 culture of cells are 15.6 x 10(11) M-1 and 210 +/- 90, respectively. Evidently, resistance of J-41 cells to alpha-interferon is connected with the absence of interferon receptors and, as a consequence, inability to interferon-receptor interaction. 相似文献

Biological diversity and the complexity of the community structure of benthic animals in different bodies of water are evaluated
using the Shannon index. The literature data on the communities in Lake Krasnoye (Karelian Isthmus, Leningrad Oblast), Shchuchy
Bay of Lake Ladoga, Neva Bay, and the eastern part of the Gulf of Finland have been analyzed. The extrema (maxima and minima)
and the inflection point of the curve of functions are determined with the help of derivatives. The rate of the secondary
succession is evaluated for the first time by the example of benthic communities. It is shown that the community structure
of bottom animals in the Shchuchy Bay ecosystem formed in the process of succession proves to be more complex than in Lake
Krasnoye and the Neva Bay communities that have been formed for a long time. Communities of bottom animals are less complex
in polluted waters of the top of the eastern part of the Gulf of Finland. It has taken 12 years to reach the maximum diversity
of the bottom animal communities in Shchuchy Bay, 16 years in Lake Krasnoye, and 7–10 years in Neva Bay. It is supposed that,
under favorable conditions in the waterbodies of a moderate climate and in the absence of heavy pollution or eutrophication,
it takes 12–14 years on average to form the most complex community structure of bottom animals (3–4 bit/spec.). The structure
of communities in polluted waters remains simple. 相似文献
