| Abstract: | Hormonal manipulation has been shown to result in less efficient bladder clearance of bacteria. We describe the use of a double antibody technique to semiquantitatively demonstrate the diminution of bladder glycoproteins from the transitional epithelium in oophorectomized rabbits. Rabbit bladder glycoprotein was isolated and used to immunize Swiss-Webster mice. Bladders of normal and oophorectomized rabbits were sequentially stained with mouse antirabbit sera and fluoresceinated goat antimouse antibody. A significant loss of bladder epithelial glycoprotein was evident in oophorectomized rabbits as compared to controls. This study, utilizing a semiquantitative immunologic staining technique, suggests an intact glycoprotein layer is important in the bladder defense mechanism. |
