[Use of MR spectroscopy in the study of the nature of paramagnetic complexes of nasal secretion].
New data are presented indicating that the electron paramagnetic resonance technique can be used to study nasal secretion paramagnetic centers. In the study 53 subjects, who were not exposed to industrial aerosols during their professional activities, were examined. It was demonstrated that nasal secretion contained paramagnetic centers bound with iron- and copper-containing proteins in the concentrations which were significantly lower than plasma had. It is postulated that metal-containing complexes may be involved in defence systems of the upper airways.
