title: Physical and chemical determinations of prostatic secretion in benign hyperplasia, prostatitis, and adenocarcinoma.
abstract: With a view to detecting early biochemical changes in diseased prostate glands, polyamines, zinc, cholesterol, and physical measurements of pH and specific gravity were determined in expressed prostatic secretion. The pH of prostatic secretion from normal men was found to be higher than previously reported in the literature. The other measured substances and specific gravity were found to be decreased in prostatitis whereas the specific gravity was markedly elevated in those patients with adenocarcinoma. Clarification of physicochemical studies on prostate secretion may lead to a system of better monitoring the course of prostate disease.
