[Effect of low-power laser irradiation on the structure and properties of protein molecules under non-specific energy absorbance]. / Vplyv nyz'koenerhetychnoho lazernoho vyprominiuvannia na strukturu ta vlastyvosti molekuly bilka za umov nespetsyfichnoho pohlynannia enerhiï.

The influence of the helium-neon laser emission on HSA was investigated at present work by means of the fluorescent probe MNBIS (4-morpholino-7-oxy-7-H-benzo-[de]-benzo-[4,5]-imidazo-[2,1-a]- izoquinolin-5-sulfonic acid) sensitive to protein conformational changes using. Fluorescence spectra parameters of the probe and kinetics of probe interaction with protein molecules were analyzed. Possible mechanisms of the helium-neon laser irradiation on water-protein solution structure are discussed.

[Changes of various physiologic characteristics in adult rats as effected by electrostatic field]. / Zmina deiakykh fiziologichnykh parametriv v organizmi zrilykh shchuriv pid vplyvom electrostatychnogo polia.

The chronic effect of electrostatic field has been studied in experiments on adult female Wistar rats. It is shown, that under these conditions the stability of erythrocyte membranes decreases, that causes their earlier hemolysis. The level of calcium and iron in blood increases, that is correlated with changes in the urea content. In the brain iron content decreases, while urea increases. The obtained results reflect the active establishment of dynamic equilibrium in conformity with this influence.
