The Effect of Retinoic Acid on Seminal Vesicle Epithelial Cell

Purpose: The seminal vesicles are androgen dependent exocrine glands producing protein-rich secretion. The retinoic acid has been implicated as a signaling molecule for the seminal vesicle development. In the present study, the effect of retinoic acid on seminal vesicle epithelial cell of neonatal mouse was investigated. Materials and Methods: Newborn male N-MRI mice were injected intraperiton...

Cystadenoma of the seminal vesicle.

Primary tumors of the seminal vesicle are extremely rare. Among them, there is a spectrum of tumors derived from both epithelium and stroma and so classified as epithelial-stromal tumors. Herein, we report a case of a cystadenoma in a 49-year-old asymptomatic man, detected in a routine ultrasonography for liver disease follow-up. The digital rectal examination detected a large mass anterior to ...

Congenital agenesis of seminal vesicle.

Congenital agenesis of the seminal vesicle (CASV) is frequently associated with congenital absence of the vas deferens (CAVD) or ipsilateral congenital vasoureteral communication. We reported two cases of a rare condition that the vas deferens open ectopically into Mullerian duct cyst associated with agenesis of the ipsilateral seminal vesicle. The diagnosis was confirmed by vasography. Transur...

Purification and properties of bull seminal plasma Ca2+,Mg2+-dependent endonuclease.

A 950-fold purification of Ca2+,Mg+-dependent endonuclease was achieved from bull seminal plasma with a recovery of 33%. The final enzyme preparation showed a single major protein band with M, = 36,000 determined by sodium dodecyl sulfate-polyacrylamide gel electrophoresis. The molecular weight of native enzyme estimated by a gel chromatography was 28,000. The specific activity of the purified ...
