[Clinical studies of gamma-seminoprotein in prostatic disease. II. Immunohistochemical study of gamma-seminoprotein].

Localization of gamma-seminoprotein (gamma-Sm) was examined using horseradish peroxidase-labeled anti-gamma-Sm antibody (Chugai Corp. Ltd., Tokyo, Japan) by the enzyme-labeled antibody method in paraffin embedded specimens of 18 benign prostatic hyperplasias and 32 untreated prostatic cancers. The level of serum gamma-Sm was also determined by enzyme immunoassay in 10 untreated patients with prostatic cancer and 18 with benign prostatic hyperplasia. Specific gamma-Sm staining was detected in prostatic glandular epithelial cells and prostatic secretion of all specimens of benign prostatic hyperplasias and a half of the specimens of prostatic cancers. Specific gamma-Sm staining was shown to correlate with histological differentiation of the prostatic cancer, but no correlation was found between specific gamma-Sm staining and the level of serum gamma-Sm.
