[Effect of temperature on the modification of spectral properties of tryptophan aqueous solutions induced by water previously treated with laser radiation].

It was shown that preliminary exposure of a solvent (water) to low-intensity laser radiation reduces the tryptophan fluorescence intensity, and this fluorescence quenching effect is retained throughout the temperature range explored (from 8 up to 50 degrees C). The effects found are interpreted as resulting from changes in solvent properties induced by the action of electromagnetic radiation on interaction of water molecules with solute.

[The adaptational changes in lipid peroxidation under the chronic action of an electrostatic field]. / Adaptatsionnye izmeneniia perekisnogo okisleniia lipidov v usloviiakh khronicheskogo deistviia élektrostaticheskogo polia.

Experiments on young puberal Wistar rats have shown that chronic effect of the electrostatic field brings lipid peroxidation (LPO) to a new level of the dynamic equilibrium. Metabolism of lipids proved to be sensitive to this factor. But the systems regulating LPO actively holds a new equilibrium state. Inert LPO products of the lipopigments type can bind vitamin E whose content in tissues remains unchanged.

[Effect of chronic effect of the electrostatic field on various biochemical indicators of the tissues]. / Vliianie khronicheskogo deistviia élektrostaticheskogo polia na nekotorye biokhimicheskie pokazateli tkanei.

The action of electrostatic field (320 kV/m) on the adaptability has been studied in experiments on young Wistar rats (females). Some parameters of carbohydrate, lipid and protein metabolism, and the process of lipid peroxidation were observed in blood serum, liver and brain. Glucose content was observed to increase in all the tissues, liver glycogen, cholesterol/phospholipid ratio. The urea and malondialdehyde increased in the liver and brain. The experiments have shown that the physiological adaptability is high.
