title: [The content of some trace elements in tissue of laryngeal squamous cell carcinoma].
abstract: The examination of the content of arsenic, nickel, copper, selenium, zinc, iron, cadmium, lead, cobalt, antimony and tin in the tissue of laryngeal squamous cell carcinoma was carried out. Material was taken from tumour of the larynx of 22 patients during laryngectomy. The control group was made up by healthy tissue of the larynx taken from 14 patients during diagnostic examinations. Trace elements were determined by means of BAIRD plasma spectrometer. Higher values of the concentration of arsenic, nickel, copper, cadmium, lead and cobalt were found in the tissue with carcinoma of the larynx as compared with the control group. The concentration of selenium, zinc, and iron in the carcinoma tissue was lower than in the healthy tissue. The concentration of antimony and tin was similar to that of the control group.
