Smooth muscle proliferation is an important and possibly androgen-dependent step in the development of atherosclerosis and BPH. Prospective studies are required to assess the effect of antiandrogens on atherosclerosis.
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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
