Abstract

The aim of the work was to study the effect of dinitrosyl iron complexes (DNIC) with a ligand based on N-acetyl-L-cysteine upon its prolonged administration into the rat body by inhalation. It was found that as a result of this, an effective transfer of stabilized forms of NO occurred through the alveolar wall into the lung tissue. Accumulation of dinitrosyl iron complexes with protein ligands in the lungs and other organs, an increase in their total NO level, as well as a significant and prolonged hypotensive effect were observed.

含 N-乙酰-L-半胱氨酸配体的二硝基铁络合物对吸入大鼠体内的影响
本研究的目的是研究以n -乙酰- l-半胱氨酸为配体的二硝基铁配合物(DNIC)经吸入长期进入大鼠体内的影响。结果发现,稳定形式的NO通过肺泡壁有效转移到肺组织中。二硝基铁配合物与蛋白质配体在肺和其他器官中蓄积,其总NO水平升高,并观察到显著和持久的降压作用。

期刊介绍: Biophysics is a multidisciplinary international peer reviewed journal that covers a wide scope of problems related to the main physical mechanisms of processes taking place at different organization levels in biosystems. It includes structure and dynamics of macromolecules, cells and tissues; the influence of environment; energy transformation and transfer; thermodynamics; biological motility; population dynamics and cell differentiation modeling; biomechanics and tissue rheology; nonlinear phenomena, mathematical and cybernetics modeling of complex systems; and computational biology. The journal publishes short communications devoted and review articles.
