Auxins (IAA, NAA, p-CPA) caused 20–30% promotion of respiration of auxin-dependent cell cultures ofNicotiana tabacum, Glycine max, Taraxacum mongolica, andAtriplex sp. and had small if any effect on respiration of auxin-independent cell cultures ofRubus sp. andScorzonera hispanica. Antiauxin (p-CPIBA) did not affect the respiration. The auxin effect on the(More)
The effect of work on a computer on the functional state of preschool children (five to six years of age) using developing software (DS) with differently colored backgrounds (lettuce green, blue, black, or graypurple) has been studied. All other characteristics of DS were alike: the same children were examined while working with each of the four(More)

The functional status of the central nervous system (CNS), the character of the regulation of the heart rhythm, and general operative efficiency were studied in 96 five-, six-, and seven-year-old children working with a personal computer (PC). The study revealed certain age-specific features in the childrens' physiological reactions to this work:(More)
