characterization of these mucosal alterations , by means of conventional histology , morphometry after microdissection , cell kinetics , mucin histochemistry and quantitative enzyme histochemistry performed with serial sections , revealed mild epithelial dysplasia , a considerable elongation and dilatation of the crypts and a marked increase of the crypt cell production , including a shift of the main proliferative compartment from the basal to the medial crypt segment as well as the occurrence of mitotic figures in the luminal epithelium .
