Mesenchymal-epithelial interactions are essential for the development of the male reproductive tract. Tissue recombination experiments have been used to define the characteristics of these interactions. When mesenchyme, embryonic connective tissue, is recombined with epithelium from another organ an instructive induction may occur in which the developmental fate of the epithelium is altered. In...

OBJECTIVE To use immunohistochemical methods to study the developing autonomic innervation of the human fetal vas deferens and seminal vesicle. MATERIAL AND METHODS Thirteen pre-natal specimens ranging in gestational age from 13 to 30 weeks were acquired following abortion or miscarriage. The overall innervation of each specimen was visualized using protein gene product 9.5 (PGP), a general n...

The results of several investigations1-5 have suggested that nucleic acids play a role in mediating the anabolic action of androgens. RNA extracted from prostatic nuclei of androgen-treated castrates enhanced the incorporation of amino acids into protein in a bacterial ribosomal system.6 An RNA preparation from the uteri of estrogen-treated rats induced morphologic changes resembling those prod...

AIM This study aims to determine the effect of seminal vesicle extract on cyclic adenosine monophosphate responsive element modulator (CREM) expression in rat Sertoli cells. MATERIALS AND METHODS This study examined the expression of CREM on 20 male rats (Rattus norvegicus) at 4 months of age, weighing 250-300 g. The rats were divided into four groups: K0, KP1, KP2, and KP3. K0 group was inje...

PURPOSE We review the functional and oncologic outcomes of seminal vesicle and prostate capsule sparing cystectomy combined with ileal orthotopic bladder substitution. MATERIALS AND METHODS Between May 2003 to April 2009 a select group of 31 patients (median age 61 years, range 30 to 77) underwent seminal vesicle sparing cystoprostatectomy for transitional cell carcinoma of the bladder. Preop...

We investigated the hormonal responsiveness of gland and stroma in the male accessory sex organs (ventral prostate, dorsolateral prostate and seminal vesicle). Immature rats (3 weeks old) were castrated and left untreated for 4 weeks and then distributed at random into 3 groups, A, B, C. The rats in groups A, B and C were injected subcutaneously with 0.2 ml of soybean oil, 5 alpha-dihydrotestos...

Background: Zinner syndrome is defined as seminal vesicle cysts with ipsilateral renal agenesis and an ectopic ureter. Symptomatic cases are very rare. In this article, we present a laparoscopic approach for a case of Zinner syndrome. Case Presentation: The patient was a 21-year-old male with difficult urination. A right seminal vesicle cyst and right kidney agenesis associated with ureterocele...

UNLABELLED The aim of this study was to elucidate the prognostic value of the immunohistochemical detection of the androgen receptor (AR) status, the chromogranin A assessment of neuroendocrine differentiation (NED) and the CD34 assessment of microvessel density (MVD) with time-to-biochemical failure among surgically treated patients with clinically localized prostate cancer. PATIENTS AND MET...

Prostatic abscess involving the seminal vesicle is a rare disease due to the widespread use of broad-spectrum antibiotics in patients with lower urinary tract symptoms. With the elevated risk of community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA), a great emphasis on its pathogenicity in prostatic abscesses is required. To the best of our knowledge, this is the first stud...

Seminal vesicle secretory protein IV (SVS IV) is perhaps the most abundant protein made by the epithelial cells of the rat seminal vesicle. In this report, we have asked whether the methylation of its gene correlates with its tissue-specific pattern of expression. Using methylation-sensitive restriction endonucleases HpaII and AvaI, we could examine seven potential methylation sites in or near ...
