[Histochemical study of the mucus in villous tumors of the colon].
The study deals with a comparative histochemical evaluation of mucus secreted by normal large bowel mucosa and that obtained from 10 villous tumors (colorectal adenoma--6 and colorectal adenocarcinoma--4). Level of production and chemical composition of mucus changed with tumor advancement: an increase in neutral mucopolysaccharides synthesis was matched by lowered production of acid ones. Also, deranged sulphatation of mucus and changes in sialomucin profile were established.
