[Alternating and pulsed magnetic fields for the treatment of dorsopathies].

The therapeutic application of isolated low-intensity magnetic field pulses (magnetic induction 150 mT) results in the significant improvement of the initial tone of microvessels and their vasomotor activity. The application of double pulses of the high-energy magnetic field (magnetic induction 1300 mT per pulse) stimulates the activity of the peripheral neuromuscular apparatus due to an enhancement of the initially low muscular tone and contractility. Moreover, it decreases the degree of manifestation of the functional state of peripheral nerves.

[Two types of metabolic regulation of phenol oxidase activity in ontogenesis of house fly].

Changes of the tyrosinase activity in ontogenesis of the house fly Musca domestica were shown to be phase-specific and ontogenetic changes of tyrosinase and dihydroxyphenylalanine oxidase activities proved to be coordinated. Ascorbic acid stimulated some ontogenetic stages of the house fly and physiological indices, such as fertility, survival at different stages, and weight of puparia. Also, ascorbic acid modulated the tyrosinase activity.
