Currently, characteristics of colonic mucin in various colonic disorders has been studied by using different staining techniques. We have attempted to see characteristics of colonic mucin of the different sites in normal subjects in this study. The biopsy specimens from 48 subjects, proved to be macroscopically and histologically normal, were obtained from the cecum, ascending, transverse, descending, sigmoid colon and rectum via total colonoscopy. Various mucin staining such as AB pH 2.5-PAS, HID-AB PH 2.5 and PAT/KOH/PAS were employed in order to see mucin characteristics of the different sites of the colon. <BR>From our observation it became clear that in the right colon eutral mucin was more dominant than in the left colon, on the contrary in the left colon asid mucin was more dominant than in the right colon. Sulphomucin and O-acylated sialomucin without vicinal diol were predominantly seen in all sites of the colon.
