We compared electrophoretic evaluation of acid phosphatase isoenzymes with spectrophotometric determination of prostatic acid phosphatase in terms of clinical utility. In all of 33 cases of prostatic carcinoma, an increased prostatic fraction was detected; in nine prostatectomized patients, this fraction returned to normal as measured by either technique. Abnormal spectrophotometric results wer...

AIMS Small cell prostatic cancer is a rare but aggressive disease. Currently, its histogenetic origin is unclear and its distinction from metastatic small cell lung cancer is challenging. The aim of our study was to determine whether the ERG rearrangement commonly observed in acinar prostatic cancer can distinguish small cell prostatic cancer from small cell lung cancer samples. METHODS AND R...

Genetic changes in epithelial cells initiate the development of prostatic adenocarcinomas. As nascent tumors grow and undergo progression, epithelial tumor cells are intimately associated with stromal cells. Stromal cells within the tumor microenvironment acquire new properties, including the capacity to promote phenotypic and genetic progression in adjacent epithelial cells. Affymetrix microar...

Stem cells are believed to regulate normal prostatic homeostasis and to play a role in the etiology of prostate cancer and benign prostatic hyperplasia. We show here that the proximal region of mouse prostatic ducts is enriched in a subpopulation of epithelial cells that exhibit three important attributes of epithelial stem cells: they are slow cycling, possess a high in vitro proliferative pot...

Symptomatic prostatic paracoccidioidomycosis (PCM) is a very rare condition; however, it may express as a typical benign prostatic hyperplasia or a simulating prostatic adenocarcinoma. This case report presents PCM mimicking prostatic adenocarcinoma. The purpose of this paper is to call the general physician's attention to this important differential diagnosis.

There are many techniques have been used in the surgical treatment of prostatitis, prostatic abscesses and prostatic cysts. Partial or complete prostatectomy, marsupialization, or debridement and drainage have all been advocated; unfortunately all of these techniques are associated with complications such as incontinence, cyst or abscess recurrence, etc. More recently, prostatic omentalization ...

The present study investigated the histological prevalence of subclinical prostatic disease in a canine mixed-breed population. The reliability of digital rectal examination (DRE) as a screening test for subclinical prostatic disease was also evaluated. DRE was performed on 500 male dogs (age range 1 to 21 years) before the dogs died of diseases not related to the prostate. Necropsies of these ...

In the present review article, the penetration of antimicrobial agents into prostatic fluid and tissue was examined. Three major factors determining the diffusion and concentration of antimicrobial agents in prostatic fluid and tissue are the lipid solubility, dissociation constant (pKa) and protein binding. The normal pH of human prostatic fluid is 6.5-6.7, and it increases in chronic prostati...

Background: Heavy metals such as cadmium (Cd2+) are natural components of the Earth's crust which can not be degraded or destroyed. Industrial, mining and agricultural activities, particularly the excessive use of phosphate fertilizers, have led to high levels of cadmium contamination at many locations worldwide. Some toxic effects of cadmium are due to its inhibition of various enzyme sys...

abstract: the prostate gland is the major accessory gland in male dogs. prostate disease is a common problem in older intact male dogs. the aim of this study was to determine prostatic dimensions by plain radiography and urethrocystography in dogs and compare them with actual sizes. plain radiography and urethrocystography were performed on 10 intact young adult male dogs. after necropsy length...
