The binding sites of lectins in parathyroid glands were determined by an immunohistochmical method in normal parathyroid gland, hyperplasia, adenoma and carcinoma, the used lectins were commercially available Glycine max (SBA), Concanavalina enciformis (Con A), Triticum vulgaris (WGA), Richinus communis (RCA), Banderiaea simplicifolia II (BSA II) and Arachis hypogaea (PNA). For normal parathyroid glands (2 cases) and hyperplasia (2 cases), WGA and BSA II were stained in cytoplasma and cell membrane. For carcinoma (1 cases), all lectins but BSA II were positively stained. In particular, SBA revealed more stronger stain than any other hystological types. From the staining patterns of lectins, it was suggested that adenomas (22 cases) be divided into one group similar to carcinoma and the others to normal parathyroid gland and hyperplasia. But there was no difference in clinical data of patients between the two groups.
