[Effect of selective polishing of teeth on local circulation in prosthetic treatment by implantation].

An effect of occlusion disorders on a regional circulation was studied in periodontal tissues of abutment teeth, antagonist teeth, periimplant zone at different stages of preparation for a prosthesis by normalization of occlusion ratios by means of selective polishing of teeth. The terms and the periodicity of selective polishing promoting redistribution of the masticating pressure were determined. The connection of these factors was examined with periodontal vessel tonicity and periimplant zone on the basis of the rheoparodontographic findings.

[Dental occlusion and pathology of periodontal inflammation].

Effect of occlusion disorders on regional circulation in periodontal tissues was studied in patients with periodontitis of medium severity. The role of selective polishing in arrest of periodontal inflammation was determined on the basis of clinical and rheoparodontographic findings. Terms and stages of selective polishing promoting redistribution of masticatory loading were determined.

[Polymeric forms of the influenza virus nucleoprotein].

Two high-molecular-weight types of in vivo formed nucleoproteins (NP) capable of reacting with anti-NP monoclonal antibodies were detected in continuous MDCK cells and primary CEFs, along with the monomeric virus NP. High-molecular NP were stable at 37 degrees C, despite the presence of dodecyl sulfate and B-mercaptoethanol, but were converted to monomeric NP at 37 degrees C in the presence of 6 M urea, 1 M NaCl, and at acid pH. Hence, high-molecular-weight NP may be the polymeric forms of NP, which are probably stabilized by noncovalent bonds.

[Effect of autoinducers of anabiosis for some microorganisms on rat liver mitochondria respiration].

2-(4-Hydroxyphenyl)ethane-1-ol (tyrosol) and 5-n-alkyl(C19,C21)resorcinols produced by some microorganisms as anabiosis autoregulators (factors d1) inhibit the electron transport and uncouple oxidative phosphorylation in the respiratory chain of rat liver mitochondria: a 50% decrease of the respiratory control is caused by 0.32-0.36 mumol of tyrosol or by 0.

[Tyrosol--the autoregulatory d1 factor of the yeast Saccharomyces cerevisiae].

The autoregulatory d1 factor of the yeast, Saccharomyces cerevisiae, that induces the transition of vegetative cells into refractory resting forms, has been isolated from the cell-free culture medium as an individual crystalline compound. It has been shown to be 2-(4-hydroxyphenyl)ethane-1-ol which is also known as tyrosol. When added to the producer culture at 5-15 microM concentration, tyrosol stimulated the endogenous respiration of cells, but inhibited at 20-80 microM concentration.
