Role of cytoskeleton in formation of airway muscle activity in the presence of nanosized magnetite

The mechanographic method was used to study the influence of iron oxide nano-powder on airway muscle activity in guinea pigs. Under the action of nanomaterial on isolated segments, amplitudes of cholinergic and histaminergic contractile reactions increased. The pre-processing of cytoskeleton by colchicines and nocodazole disintegrators led to an increase in the mechanical stress of segments under the action of carbacholine and histamine.
