The researchers examined about a thousand workers at the Krasnoyarsk and Novokuznetsk works, where aluminium is obtained from bauxite. Part of the workers suffered from fluorosis. Fluorosis is a heavy disease affecting many organs and tissues, causing neuropsychic disorders, neuroses and pain syndrome. It often results in disablement. Palm prints of the examined persons were taken with the help of printer's ink. In line with that, the researchers took their blood tests and investigated some proteins of erythrocytes, leucocytes and serum. Based on the analysis of these proteins, the researchers managed to group all the persons under investigation according to genetic similarity. When the specialists completed all calculations, it turned out that eight genetically similar groups of workers consisted of persons affected by fluorosis, and five groups consisted of healthy persons.
After the researchers compared the blood proteins analysis results, line patterns on the palms or dermatoglyphic characteristics, with each worker's fluorine poisoning data, it turned out that the above characteristics correlate with each other to a large extent. On the one hand, the higher risk of falling ill with fluorosis is connected with a certain genotype and, therefore, with a certain set of blood proteins. On the other hand, individual predisposition to professional fluorosis or resistance to it can be judged by the directions of main lines on the palm, location of the so-called axled triradius that is in the center of the palm, and by saturation of patterns on some sections of the left palm.
Th researchers connect this phenomenon with the fact that the people born and raised in the vicinity of aluminium works are exposed to fluorine impact as early as in embryo, and they often have their palm lines direction changed. Parallel to that, adaptation mechanisms get switched on in the organism. As a result, these people become more resistant to fluorine in the conditions where its concentration is constantly high.
Thus, the elaborated method may help to determine whether a person can be engaged in aluminium smelting with no damage to health. To this end, the person's palm should be investigated and the blood test taken.
By the way, physicians have long used dermatoglyphic characteristics to timely discover various pathologies, for example, predisposition to cardiac infarction.
