Attention has previously been drawn to a specific effect of NHCP on embryonic Pleurodeles cell differentiation. With a modified NHCP labelling technique, autoradiography has revealed a cytoplasmic concentration of labelled NHCP and has not revealed any difference between homospecific and heterospecific NHCP penetration. 相似文献

Mice treated with bovine gamma globulins showed an increased resistance to Salmonella typhimurium infection. This phenomenon seems to be bound to an increase of peritoneal macrophage phagocytic activity, as shown by the method of chemiluminescence, in experiments performed on peritoneal macrophages from mice treated with bovine gamma globulin. 相似文献

Zusammenfassung Durch Lösung von 0,1% Vanadiumoder Nickel-Naphthenat in Kohlenwasserstoffen kann deren Durchtritt in die Zelle der HefeCandida lipolytica elektronenmikroskopisch verfolgt werden. Die Kohlenwasserstoffe durchdringen die Zellwand, reichern sich an der Zytoplasmamembran an und verursachen im Zellinnern reiche Veränderungen. Diese beweisen meistenteils die Schlüsselaufgabe der Zytoplasmamembran, den direkten Kontakt der Kohlenwasserstoffe mit den Oxydationsenzymen zu vermitteln. 相似文献

The SCE frequency induced by Thiotepa and the effect of this antineoplastic drug in combination with caffeine have been studied in cultures of human peripheral blood. Caffeine was found to enchance SCE and breakage frequencies induced by Thiotepa in human lymphocytes. 相似文献

The levels of beta-trace protein and lysozyme were estimated in amniotic fluids from normal fetuses and from fetuses with neuraltube defects. The values of these proteins in normal amniotic fluids were found to be similar to those detected in fetuses with anencephaly and spina bifida. The levels of lysozyme were shown to be correlated with gestational age. 相似文献

Summary Catecholamine release evoked from isolated perfused bovine adrenals by Ba+2 or Cs+ is enhanced by lidocaine or by a calcium-free medium. The action of Cs+ therefore differs from that of K+ or Rb+ in adrenal medulla. Divalent and monovalent metallic cations of relatively large atomic weight like Ba+2 and Cs+, probably penetrate the cell more easily than small highly charged ions and act intracellularly to cause adrenal catecholamine release. Local anesthetics and calcium-free media may allow greater influx of Ba+2 and Cs+ into adrenomedullary cells.Acknowledgment. This work was supported by NIH, grant No. AM16153. 相似文献

Microspectrofluorometric methods have been used to study the kinetics of the increase of fluorescence due to the intake of Benzo(k)Fluoranthène and Benzo(a)Pyrène in single living L cells. A computer program based on the methods of the least square fit has allowed the determination of the kinetic parameters. The results show that pinocytosis cannot be the unique mechanism of intake. 相似文献
