title: [Mucin histochemical changes in various colo-rectal polyps in relation to carcinoma of the large bowel].
abstract: 210 various colo-rectal polyps including 46 inflammatory polyps, 21 juvenile polyps, 9 hyperplastic polyps, 65 tubular adenomas, 51 familial polyps, 11 villous adenomas, 7 adenomatous polyps with focal cancer, and 14 carcinoma of the large bowel were investigated by HE,HID-AB,PAT-KOH-PAS staining in order to study the mucin changes of these lesions. N-acetylated and C7,C9 O-acetylated sialomucin were mainly obtained in those adenomas with moderate and severe dysplasia (55-64.3%) and the proportion was even higher in cases of villous adenomas, familial polyps, adenomas with focal cancer and advanced carcinoma. These mucins might be assumed as a criteria in representing malignant transformation.
