[Factors influencing formation of dinitrosyl complexes of non-heme iron in the organs of animals in vivo]. 1977

A F Vanin, and S V Kiladze, and L N Kubrina

The formation of paramagnetic non-haem iron dinitrozyl complexes (2,03 complexes) in mouse liver has been detected, when these animals were exposed to a diet with high content of nitrite or nitrite and iron salt. These complexes appeared after 3-5 days and their content was kept at the same level during a month. The 2,03 complexes content in mouse liver was 3 times higher for mice which were exposed to the diet with nitrite and iron salt than for those on the diet only with nitrite. While the liver preparations of experimental mice were treated with NO in vitro the 2,03 complexes content increased in the liver and reached the same level for all experimental mice. It has been supposed that the 2.03 complexes formation was limited in mouse liver in vivo, both by NO production in the liver and by the content of the more labile form of non-haem iron, which was primarily incorporated into the complexes.

D009609 Nitrous Oxide Nitrogen oxide (N2O). A colorless, odorless gas that is used as an anesthetic and analgesic. High concentrations cause a narcotic effect and may replace oxygen, causing death by asphyxia. It is also used as a food aerosol in the preparation of whipping cream.

D004578 Electron Spin Resonance Spectroscopy A technique applicable to the wide variety of substances which exhibit paramagnetism because of the magnetic moments of unpaired electrons. The spectra are useful for detection and identification, for determination of electron structure, for study of interactions between molecules, and for measurement of nuclear spins and moments. (From McGraw-Hill Encyclopedia of Science and Technology, 7th edition) Electron nuclear double resonance (ENDOR) spectroscopy is a variant of the technique which can give enhanced resolution. Electron spin resonance analysis can now be used in vivo, including imaging applications such as MAGNETIC RESONANCE IMAGING.
