Three predominant patterns were identified: (1) normal mucosa, showing normal histological architecture and secretion of sulphomucins; (2) N+ type, histologically normal mucosa with predominance of sialomucins; (3) transitional mucosa; hyperplastic mucosa secreting sialomucins. Hyperplastic changes were ...
In the mouse and rat, sialomucins with some neutral mucins are found. In hamsters, dogs, non-human primates and humans both sulfomucins and sialomucins may be seen in the brush border.256 Some compounds may induce qualitative and quantitative changes in mucin content in the colonic mucosa ...
Carcinogenesis in the colonic mucosa is a complex, mul- tistep process. Genetic anomalies occur in the epithelial cells long before there is a visible change in the mucosal structure. These genetic changes alter the normal cellular response to factors that regulate growth and differentiation.3 The...
about the role of the different monosaccharides to determine the significance of mucins in the physiology and pathology of the bowel.In this study different carbohydrate structures have been investigated by fluorescence microscopy in normal, hyperplastic, adenomatous, and carcinomatous colonic mucosa. Lecti...
3). A biopsy of the colonic mass was performed, and results showed mild acute inflammatory infiltrates with hyperplastic features. A polypectomy was also performed, and the histology showed tubular adenoma with low-grade dysplasia. The patient subsequently underwent chemotherapy and radiotherapy for his...
(b) True Negative: Mild colitis, non-neoplastic mucosa. (c) False Negative: Individual cells and small collection of tumor cells are not detected. On the other hand, lymphoplasmacytic infiltrate causes inappropri- ate detection. (d) False Positive: Concentration of lymphocytes. The segments ...

hyperplastic changes in the adjacent mucosa which expressed higher levels of epidermal growth factor receptor, basic fibroblast growth factor, and vascular endothelial growth factor, and lower levels of interferon-尾 than did the control mucosa, which directly correlated with the degree of hyperplasia. ...

Precisely distinguishing between hyperplastic and adenomatous polyps and normal human colonic mucosa at the cellular level is of great medical significance. In this work, multiphoton laser scanning microscopy (MPLSM) was used to obtain the high-contrast images and the morphological characteristics from ...
