[Effects of distorted geomagnetic field on the functioning of systems supporting rat's bone matrix adaptation and metabolism in open field].

Physiological responses of rats to daily 30-minute exposure to distorted geomagnetic field (DGMF) over 3 and 7 days and their reaction to open field following the exposure were studied. Increases in blood 11-oxycorticosteroids (11-OCS) were observed equally after 3- and 7-day DGMF exposure, whereas adrenal 11-OCS was found increased only on DGMF day-3; neither adrenaline in the adrenals nor glycogen in the liver were affected. On DGMF day-7, activation of bone matrix demineralization manifested itself by increased phosphorus and decreased calcium in blood, and activation of acidic phosphatase in serum. Rats reacted to open field by increases in blood and hepatic 11-OCS, reduction in adrenaline in the adrenals and glycogen in the liver, increase in serum free oxyproline and acidic phosphatase activation, and inhibition of alkaline phosphatase. Seven-day DGMF heightened or aggravated the reaction to open field.

[Effect of the perturbed geomagnetic field on the metabolism of the rat connective tissue during heat exposure].

The biochemical data of the researches of the perturbed geomagnetic field influence on the metabolism of the rat's connective tissue by the heating are presented. The possibility of adrenal glands reaction modification under using the perturbed geomagnetic field after high temperature is shown.

[The reaction of the systems of hormonal mediator regulation to a weak geomagnetic field against a background of ionizing radiation exposure]. / Reaktsiia sistem gormonal'no-mediatornoi reguliatsii na gipogeomagnitnoe pole na fone vozdeistviia ioniziruiushchego izlucheniia.

Guinea pigs were subjected for 30 minutes to geomagnetic field of ten times decreased induction. The increase of epinephrine and histamine level in blood was observed. The decrease of histamine and serotonin concentration as well as normalization of epinephrine level were found when the influence of weakened geomagnetic field was stopped. Preliminary 2 Gy X-radiation resulted in the suppressed response of the organism to the weak geomagnetic field.

The biochemical data on the influence of electromagnetic fields in microwave range on the hormonal-mediator regulation systems are presented. The possibility of biological effects modification under combined action of microwave radiation and foreign protein is discussed.

The biochemical data on the influence of perturbed geomagnetic field on the hormonal-mediator regulation systems are presented. The possibility of biological effects modification under combined action of perturbed geomagnetic field and high temperature of environment is discussed.

[Effects of perturbed geomagnetic field on connective tissue metabolism and some systems of homeostasis after hydroxyapatite implantation]. / Vliianie iskazhennogo geomagnitnogo polia na metabolizm soedinitel'noi tkani i nekotorye sistemy gomeostaza pri implantatsii gidroksiapatita.

The influence of perturbed geomagnetic field (PGMF) on glucocorticoid, epinephrine, hydroxyproline content in intact rats and after intramuscular implantation of demineralized bone matrix and combined (hydroxyapatite/bone meal) samples was investigated. It was found that the exposure of the intact rats to PGMF led to decrease in free and peptide-bound hydroxyproline in plasma. In the rats with hydroxyapatite/bone meal samples placed in ectopic sites the exposure to PGMF normalized hydroxyproline, glucocorticoid and epinephrine content.

[Characteristics of the catecholamine system in patients with endogenous depression before and after sleep deprivation therapy and tricyclic antidepressants]. / Osobennosti katekholaminovoi sistemy u bol'nykh éndogennymi depressiiami do i posle terapii deprivatsiei sna i tritsiklicheskimi antidepressantami.

Results are presented of the study of catecholamine system in endogenic depressive patients before and after treatment with sleep deprivation (26 patients) of tricyclic antidepressants (30 patients). Epinephrine, norepinephrine, and DOPA excretion were studied as related to clinical picture of the syndrome (2 groups: melancholic and anesthetic depressions). Sleep deprivation therapy was an effective method, as indicated by both clinical and catecholamine system signs.

[The combined action of microwave irradiation and hypoxia on the biogenic amine content of the blood in guinea pigs in anaphylactic shock]. / Kombinirovannoe deistvie mikrovolnovogo izlucheniia i gipoksii na soderzhanie biogennykh aminov v krovi morskikh svinok pri anafilakticheskom shoke.

The repeated effect of microwave radiation on guinea pigs was shown to arrest the anaphylactic shock and the related changes in histamine, epinephrine and norepinephrine content in the blood. The long-term adaptation of animals to hypoxia prevented this effect.

[The combined action of ionizing radiation and a heat load on the content of biogenic amines in the blood of guinea pigs with anaphylactic shock]. / Kombinirovannoe deistvie ioniziruiushchego izlucheniia i teplovoi nagruzki na soderzhanie biogennykh aminov v krovi morskikh svinok pri anafilaticheskom shoke.

The anaphylactic shock and alterations in the epinephrine and norepinephrine content of the blood were inhibited in guinea pigs which were repeatedly kept at high temperature (50 degrees C). Preirradiation with a dose of 1 Gy prevented this effect.

[The modification of the effect of microwave radiation on the biochemical processes in anaphylactic shock by using exposure to a weak and perturbed geomagnetic field]. / Modifikatsiia vliianiia mikrovolnovogo izlucheniia na biokhimicheskie protsessy pri anafilakticheskom shoke s pomoshch'iu vozdeistviia oslablennogo i iskazhennogo geomagnitnogo polia.

Repeated exposure of guinea pigs to microwave radiation (1 mW/cm2) caused in some animals inhibition of anaphylactic response accompanied by increasing the content of histamine, epinephrine and norepinephrine in the blood. This increase was more pronounced in irradiated guinea pigs died from anaphylactic shock than in nonirradiated animals. The long-term stay in the perturbed and weak geometric field reduced the effect induced by microwave radiation.
