  • Title: [Histochemical study of rabbit duodenal mucosa carried out using lectins].
    Author: Bosco L, Saccia M, Bufo P.
    Journal: Boll Soc Ital Biol Sper; 1990 Apr; 66(4):309-14. PubMed ID: 2390220.
    Abstract:
    The Authors report histochemical findings about rabbit's duodenal mucosa. The present study has been carried out using five different lectins (Peanut Agglutinin (PNA), Dolichos Biflorus Agglutinin (DBA), Wheat Germ Agglutinin (WGA), Soybean Agglutinin (SBA), Ulex Europaeus Agglutinin I (UEA-I). These lectins have been labelled with Horseradish Peroxidase and binding sites have been stained with 3-3' Diaminobenzidine, according to Farragiana et al. The PNA reacted with the glandular cells, while the reaction was negative in the superficial cells. The DBA reacted exclusively with the glandular cells. The superficial and the glandular cells showed strong positive binding sites to the WGA and slight positive binding sites to the SBA. The UEA-I did not react with the epithelial cells. The presence of binding sites for the lectins we have used in the present study, shows a different glycoprotein composition of the cellular secretion, in comparison with the other animals we have already studied. In addition, these lectins can not be used as cellular differentiation markers in the epithelial cells of the rabbit's duodenal mucosa.
