We carried out histochemical investigations of lectin binding patterns in order to elucidate the characteristics of junctional epithelium (JE) regenerated from oral gingival epithelium (OGE). The maxillae and associated soft tissues were removed from rats under ether anesthesia immediately, 5, 10, 15 and 20 days after gingivectomy of the upper left palatal gingivae. Formalin-fixed, paraffin-embedded sections were reacted histochemically with Ulex europaeus agglutinin-I, peanut agglutinin, soybean agglutinin or wheatgerm agglutinin labeled with peroxidase. The lectin binding patterns in the regenerated epithelium were different from those in the OGE after the regenerated epithelium had developed morphologically into the JE, even though the latter was derived from the former. These reactions were the same as those in the reduced enamel epithelium. These results indicate that the expression of glycoconjugates in regenerated epithelium derived from the OGE has a tendency to change after reconstruction of the JE.
