[Kinetics of bilayer lipid membrane formation].

Methods of irreversible thermodynamics are used to describe some kinetic processes on lipid membranes (for example, growth of the black spots during bilayer formation, the spreading of shimming lens etc.). The equation derived here shows the balance of the membrane system energy. Although this equation is generally only a boundary condition for the corresponding hydrodynamic problem it could be directly applied for analysing the bilayer formation processes. The application of this theory to experimental results permitted a determination of the membrane viscosity, and this was found to be about 10 P for ox brain lipids.

[Kinetics of lens formation on phospholipid membranes].

Kinetics of lens formation on phospholipid membranes of different thickness (50-5 nM) has been investigated. It has been shown that lenses on the "gray" membranes (approximately 50 nM) are stabilized when alternating voltage (100-500 mV) of high frequency is applied. Semiempiric equation is used for the description of the spreading of lenses. Addition of florizin to the adjacent water solutions leads to an appearance of the slow relaxation component of the lens base radius. The results obtained show that the swimming lens method may be utilized for the investigation of the slow interaction processes between the membrane and their modifiers.

[X-ray monitoring in dental implantology].

The authors analyze x-ray findings in 268 patients before, immediately after implantation, and in the course of subsequent orthodontic treatment and in remote periods after it. Methods of examination and the principal x-ray parameters are discussed that were taken into consideration in the treatment making use of artificial implants.
