Disparities of conjugating protective enzyme activities in the colon of patients with adenomas and carcinomas

Figure 1 Flow-cart: Glutathione S-transferase- and uridine glucuronosyltransferase activities examined from biopsies of adenoma and carcinoma patients. The number of patients in each type of neoplasia, the number of biopsy sites and the number and type of enzyme assays performed per site are shown. GST: Glutathione S-transferase; UGT: Uridine glucuronosyltransferase.

Figure 2 Distribution of enzyme values of uridine glucuronosyltransferase and glutathione S-transferase in the colon mucosa of the transversum of adenoma and carcinoma patients. The correlation between uridine glucuronosyltransferase (UGT) and glutathione S-transferase (GST) over the range of enzyme activities is illustrated in the colon transversum of 39 patients.
