Abstract
The possibility of water-soluble dinitrosyl iron complexes (DNIC) with thiol-containing ligands introduction into lungs and other tissues of mice by free inhalation of little drops (2–3 microns diameter) of the solutions of these complexes was investigated. Little drops of 2–20 mM solutions of the complexes were obtained by using an inhalation apparatus (compressor nebulizer). A cloud of these little drops was then inhaled by animals in a closed chamber. A maximal amount of protein-bound DNICs formed in mouse lungs was 0.6 micromoles per kilogram of tissue weight. The amount of DNIC in lungs, liver and blood decreased to the undetected level within 2–3 hours after inhalation. No cytotoxic effect of DNIC formed in lungs on Mycobacterium tuberculosis was found in mice infected with these mycobacteria.
