A high content of total glutathione and high activities of both GSH S-aryltransferase (CDNB) and GSH peroxidase were found in different segments of the human intestinal mucosa comparable to findings in human gastric mucosa. Intraindividual comparisons of tumorous and nontumorous tissue specimens in patients with adenocarcinomas of the colon and rectum revealed no marked differences in their glutathione content and enzyme activities except in the sigma, where we found significantly lower GSH concentrations and higher GSH S-aryltransferase activities in the carcinomatous tissue. gamma-Glutamyl-transpeptidase activity, a marker of neoplastic cell growth in experimental hepatocarcinogenesis, did not differ between tumorous and nontumorous tissue areas. The presence and high activity of the GSH-dependent enzyme system in different segments of the human intestinal mucosa may reflect its role in the defense against toxic and putative carcinogenic xenobiotics entering the body via the gastrointestinal tract.
