Effect of Nanodisperse Ferrite Cobalt (CoFe2O4) Particles on Contractile Reactions in Guinea Pigs Airways

The effect of nanopowder CoFe 2 O 4 on contractile responses of smooth-muscle segments of guinea pigs airways was studied by mechanography. Both in vivo inhalation of nanopowder aerosol or in vitro application of nanopowder to isolated airway segments increased the amplitude of contractile responses to histamine and potentiated the dilatory reaction to adrenergic salbutamol.
