PROGRAMMING AND ANALYTIC SPECTROMETRIC COMPLEX FOR NITROSAMINES IDENTIFYING
Scheme of nitroso compounds load on a human being
Nitrosamines (NA) have a wide a wide range of carcinogenic action; tumors may arise both under the action of nitrosamines and as a result of nitrosation of their non-cancerous precursors – nitrates, nitrites, amines and a number of other nitrogen-containing substances. There are singled out such characteristic properties of NA as their chemical resistance, high mobility in the ecosphere and a possibility of exogenous and endogenous formation from the precursors. As it is seen from the scheme where it is described the process of NA entering into the human body, this class of compounds includes various exogenous sources from the environment, indicating their interrelation with an endogenous synthesis of these compounds in the human body.

An increase of NDMA concentration in biological fluids of an organism may give rise to the oncological alertness. In cases when high NDMA concentration is associated directly with the presence of a tumor in the body, monitoring of this indicator may be useful for control of treatment effectiveness.
High concentration of NDMA in biological fluids may be one of the criteria for formation of oncological risk groups and may be applied along with the UBC and CYFRA21-1 markers in the quality of one of the additional diagnosis tests to detect bladder cancer (act of introduction of the technology, certificate № 460/2007 from October 29, 2008).
