Red and blue distinctive mucin-histochemical types of Japanese colorectal mucosa.
Mucin-histochemical characteristics of normal human colorectal mucosa were investigated utilizing Culling et al.'s staining method which distinguishes the mode of C8-O-acylation of sialomucins. Normal mucosae of cecum, ascending, transverse and descending colon and rectum were obtained from autopsy and biopsy material. Japanese colorectal mucosa stained either entirely red or entirely blue, in contrast to previous reports dealing with Caucasians where all the normal mucosa reportedly stained red. The ratio of red to blue colon cases varied to some extent with age, i.e. it was found to be 1:1 in children aged 0 to 4, 2:1 in the 5-20 age group, and 4:1 in people older than 21 years, suggesting a tendency of shift from blue to red during early life in Japan. Each individual Japanese adult colorectal mucosa may thus be classified into either red or blue type mucin-histochemically.
