Chironomus (diptera) polytene chromosomes functional activity under the influence of cholinotropic preparations
Morphometric analysis of nucleolar organizer (NO), Balbiani rings (BR) - BR<sub>B</sub>, BR<sub>1G</sub>, BR<sub>2G</sub>, chromosome I arm puff B, chromosomes compactness activity change under the influence of cholinotropic preparations was carried out. Most sensitive criterion - chromosomes compactness is, most stable under the influence of stress - NO is. Atropine and pilocarpine antagonistic effect on the polytene chromosomes (PC) sites activity pilocarpine manifested itself in functional activity and restoration period duration change: on cholinoblocker effect activity decreased, while on cholinomimetic effect activity increased.
