Correlation between the levels of certain carcinogenic and anticarcinogenic trace elements and esophageal cancer in northern Iran.

Levels of four carcinogenic (Ni, Fe, Cu, Pb) and four anticarcinogenic (Zn, Se, Mn, Mg) trace elements were measured in hair samples from esophageal cancer patients, their unaffected family members, and members of families with no history of cancer. Measurements were also made in non-esophageal cancer patients, using atomic absorption spectroscopy, inductively coupled plasma-emission spectroscopy, and neutron activation analysis. The results showed that Ni and Cu concentrations were significantly higher and Mg and Mn concentrations were significantly lower in all cancer cases. Levels of Zn, Fe, Se, and Pb were not significantly different in the above-mentioned groups. In addition, the serum albumin fraction, which is reported to have antioxidant activity, was found to be significantly lower among esophageal cancer patients.

Regional variation in As, Cu, Hg, and Se and interaction between them.

A comparative survey of trace elements in hair samples from three different regions of the world was carried out. The concentrations of the same trace elements in tissues from infants and adults from Glasgow are also presented. It was found that the Se levels in hair samples from Iceland are significantly lower than the levels found for the Glasgow area. The level of Hg was in the same range as that for the Glasgow area and the As level is much lower in Iceland. Comparison of the levels of Hg, As, and Se in hair samples from Iran and Glasgow revealed significantly lower levels of these trace elements in samples from Iran, but the Cu levels were similar. Comparison of adult and infant levels of Se and Cu revealed fetal storage of Cu in the livers of infants. Arsenic levels were higher in adult tissues. In the study of the interaction among trace elements in human tissues, a positive correlation between Hg and Cu in liver samples from the Glasgow area and hair samples from Iran was found. A positive correlation between Se and As was also found in spleen and lung tissues.

Bromine and selenium in human aorta.

The bromine and selenium concentrations of healthy and atheromatous human aorta and of other organs are reported. No relation between age and concentration in the aorta is found. The selenium levels of the aorta are similar to those of other internal organs; the content of the three layers show no significant differences. The bromine concentrations of the media are higher than those of the other layers, which are similar to those of the internal organs. A possibly greater concentration of bromine in atheromatous medial tissue is indicated.
