The lectin-binding patterns in the testis of the sexually matured Jindo dog were investigated to study the distribution of glycoconjugates in the seminiferous tubule under light and transmission electron microscopy. Positive reactions to Wheat germ agglutinin(WGA) and Dolichos biflorus agglutinin (DBA) were observed in the Sertoli cell and in the residual body of spermatid with a stronger reaction in the Sertoli cell to the lectins than in the residual body. Strong reactions to Soybean agglutinin(SBA) and Peanut agglutinin(PNA) were observed in the acrosome vesicles of the Golgi- and cap-phase spermatid, while a moderate reaction was observed in the acrosome-phase, maturation-phase spermatid and the residual body. The acrosome area of the spermatid reacted intensively to Griffonia simplicifolia agglutinin( GS-I) when the cell was in the acrosome-phase and maturation-phase, and the same reaction to the GS-I was observed in the residual body. However, the seminiferous tubule did not react to Ulex europeus agglutinin I(UEA-I). The gold-labelling of the Sertoli cells with DBA resulted in positive reactions of the Sertoli cell column and processes when observed under the electron microscopy, while the Golgi-, cap- and acrosome-phase spermatids reacted positively to SBA in the peripheral low-dense area of the acrosome vesicle of spermatid. Based on these results, we concluded that differences in the lectin-binding pattern of the seminiferous tubules were recognized in the Jindo dog compared to other animals.
