Macrophages in Prostatic Fluid

Abstract
Non-specific esterase staining was useful in the detection of macrophages in prostatic fluid (PF). In the early stage of acute prostatitis, most of the leukocytes in a smear of PF took up the stain, suggesting the dominant participation of macrophages in the inflammatory area in this stage of the disease. In chronic prostatitis, only a few leukocytes took up the stain. In female acute cystitis, none of the large numbers of leukocytes exhibited staining at any stage of the disease. The reason for this is still to be determined. Frozen sections of prostatic tissue from patients with chronic prostatitis revealed similar cells around the acini. These appeared to be the source of the macrophages which appeared in the PF.
