It was shown previously that colonization of the frog urinary bladder by gram-negative bacteria leads to decreased ability of antidiuretic hormone to reabsorb water from the urinary bladder (Fock et al. J. Exp. Zool., 2013, 319A: 487-494). In the pre

[Protective effect of gangliosides against the toxic action of bacterial lipopolysaccharide of various serotypes on PC12 cells]

Autor: Iu A, Vlasova, L V, Baiunova, E I, Mikurova, Iu D, Liakhovnenko, S D, Nikolaeva, R G, Parnova, N F, Avrova

Publikováno v: Rossiiskii fiziologicheskii zhurnal imeni I.M. Sechenova. 99(7)

The effect of bacterial lipopolysaccharide (LPS) from E. coli on the viability of PC12 neuronal cell line was studied. LPS of 0111:B4 serotype and LPS of 055:B5 serotype were shown to have toxic effect on PC12 cells. But the toxic effect of LPS of 01

[Gram-negative bacteria influence on the ability of the arginine-vasotocin to stimulate osmotic permeability of the frog urinary bladder epithelium]

Autor: E A, Lavrova, L S, Gretchenko, R G, Parnova, E M, Fok

Publikováno v: Rossiiskii fiziologicheskii zhurnal imeni I.M. Sechenova. 98(4)

The influence of endogenous gram-negative bacteria colonizing the mucosal epithelium of frog Rana temporaria L. urinary bladders (FUB) on arginine-vasotocin AVT-stimulated osmotic water flow in isolated urinary bladders was investigated. 170 animals

[Regulatory interconnections of cyclooxigenase and inducible no-synthase in urinary bladder epithelial cells of the frog Rana temporaria under action of bacterial stimuli]

Autor: V T, Bakhteeva, T M, Fedotov, S D, Nikolaeva, E A, Lavrova, E M, Fok, R G, Parnova

Publikováno v: Zhurnal evoliutsionnoi biokhimii i fiziologii. 47(1)

Earlier we have shown that in epithelial cells of the frog urinary bladder under action of bacterial lipopolysaccharides (LPS) there is activated expression of inducible NO-synthase (iNOS) and there is increased the NO production, which can play an i

Publikováno v: Rossiiskii fiziologicheskii zhurnal imeni I.M. Sechenova. 95(3)

Since Gram-negative bacteria are known to be present in the cavity of urinary bladders in amphibian species, it was interesting to study the effect of bacterial endotoxins on epithelial signaling network which provides the arginine-vasotocin-induced

Publikováno v: Tsitologiia. 50(10)

We have shown previously that endogenous NO modulates the effect of arginine-vasotocin on the increase in the osmotic water permeability of the frog urinary bladder epithelium. The aim of the present work was to develop a procedure of cultivation of

Publikováno v: Zhurnal evoliutsionnoi biokhimii i fiziologii. 44(3)

The activity of arginase converting arginine into ornithine and urea is of particular interest among many factors regulating NO production in the cells. It is known that by competing with NO-synthase for common substrate, arginase can affect the NO s
