Lm. Livanova et al., PREVENTIVE EFFECT OF NEGATIVELY CHARGED A IR IONS ON RATS WITH DIFFERENT TYPES OF BEHAVIOR IN ACUTE STRESS, Zurnal vyssej nervnoj deatelnosti im. I.P. Pavlova, 46(3), 1996, pp. 564-570
Typological characteristics of behaviour of 63 male white rats weighin
g 200-250 g were estimated by their locomotion in the open field. Acut
e stress was induced by putting the rats into narrow tubes for 1 h. Pr
ior to the experiment, the rats were exposed to the air ions produced
by Chizhevsky airionizer (<<Elion-132>>) for 2 h daily within a week.
It was found out that the expression of separate pathological stress-i
nduced changes depended on typological characteristics of rats. The ai
r ions were shown to prevent completely the development of physiologic
al changes caused by acute immobilization, including arterial pressure
increase, gastric mucosa injuries (erosions, haemorhage), changes in
respiratory enzyme acrivity (succinate dehydrogenase and NADH-dehydrog
enase) in brain cells, cardiac and adrenal mass increase in rats with
the active type of behaviour.
