Morphometric analysis of nucleolar organizer (NO), Balbiani rings (BR) - BR B , BR 1G , BR 2G , 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.
