Primary cancer of the liver, especially common in inter-tropical Africa and South-East Asia, still remains inaccessible to a really effective therapy, except for a rapid surgical excision. Improvement of its particularly poor prognosis requires therefore early screening based on reliable biological markers. Following alpha-feto-protein, various parameters have been proposed: enzyme, ferritin, desialylated serum protein, decarboxylated prothrombin... However, alpha-feto-protein remains, in practice, the reference diagnostic test, in spite of a moderate specificity below 500 ng/ml and the fact that it is frequently missing in early cancers. Its diagnostic score may be improved either by the use of monoclonal antibodies, or by determining the ratio of fucosylated form, or by concomitant use of other markers: alpha-L-fucosidase, decarboxy-prothrombin.

This study reports the ultrastructural detection of fucosyl residues at the surface of axenically grown roots of Zea mays. The method used involved sequential binding of UeA lectin to the root and coupling of the bound UeA with fucosyl ferritin. Superficial dense ferritin labelling was found in the slime droplet ensheathing the root cap and in the external layer of the three-layered epidermal root surface. This pattern of binding of the fucose-specific lectin UeA suggests an overall distribution of the fucosyl residues on the root surface. Their localization within slime components of the root cap and the root epidermis is also assessed by the use of PATAg controls. Treatment of whole roots with alpha-L-fucosidase was ineffective in removing the fucosyl residues present at the root surface. The biological role of the fucosyl residues at the root-soil interface is discussed.
