title: Estradiol and testosterone in minor salivary glands of Sjögren's syndrome.
abstract: Nine patients with Sjögren's syndrome were studied in terms of estradiol, testosterone, and dihydrotestosterone in the labial minor salivary glands using the peroxidase-antiperoxidase method. In normal controls in women, estradiol was positive in the epithelial cells of duct, but testosterone and dihydrotestosterone were negative or doubtfully positive by case. Thus, it seems that there is a sex difference of receptors in the ductal epithelia. In the labial minor salivary glands of the patients, all estradiol, testosterone, and dihydrotestosterone were positive. As the background of Sjögren's syndrome, it seems that there is an influence of sex hormones.
