Effect of EHF radiation on metabolism of Cyanobacteria spirulina platensis and other photosynthesizing organisms.

A stimulatory influence of EHF radiation on the growth and physiological activity of photosynthetic organisms is shown. Some primary responses to this action are studied. Oxygen is considered to be of great importance in the mechanism of the stimulators effect of EHF radiation.

[The selenium haemostasis during experimental anaphylaxis reaction in rats treated with reduced glutathione and selenium enriched spirulina]. / Gomeostaz selena pri éksperimental'noi anafilaksii u krys na fone priema vosstanovlennogo glutationa i selenobogachshennoi spiruliny.

The main events caused by anaphilaxis in selenium haemostasis in rats include significant increase of selenium excretion with urine (6.36 +/- 1.18 nM Se/18 h., n = 10, compared with 1.72 +/- 0.38 nM Se/18 h., n = 10) and decrease of selenium plasma/selenium erythrocytes ratio from 0.939 to 0.791. Reduced glutathione (G-SH) administration led to 1.5-fold decrease of plasma selenium level and 1.3-fold increase of selenium concentration in intestinal walls of sensitized rats (r = -0.720, P < 0.001). Chromatographic separation of plasma proteins showed that intragastric intubation of G-SH to sensibilized rats significantly decreased the protein P content and did not influence the concentration of Se-GSHPx, thus indicating the local selenium acceptor role of G-SH. G-SH administration did not influence the intestinal permeability in sensitised rats while use of complex additive: G-SH and selenium enriched spirulina--normalized the latter parameter and the ratio of protein P/Se-GSHPx in plasma.

Novel concepts of the causes of EHF-radiation-induced stimulating effects.

This article reviewed our investigations and the literature on the interaction of EHF radiation with biological objects. This allowed us to advance the general mechanism for the effect of millimetric waves on photosynthesizing organisms.
