BACKGROUND We describe a safe and easily reproducible technique to control Santorini plexus during radical retropubic prostatectomy (RRP) which uses simple digital dissection. METHODS We retrospectively reviewed 56 consecutive patients who underwent RRP for clinically localised prostate cancer from November 2008 to November 2010. Santorini plexus was isolated and secured in all patients using...

The microscopic vascular pattern of the rumina! wall of the sheep was studied by means of an India ink injection method followed by clarification in methyl salicylate. Both the epithelium and the tunica muscularis receive blood from a submucosal arterial plexus. Yenules arise from the lower regions or bases of the papillae as well as from an inter-muscular plexus. These join the submucosal veno...

objective: in previous studies it has been emphasized that the site of morphine action may be either in the embryo or the placenta. in the present study, we attempt to identify the site of morphine action on the fetal section of wistar rat placenta by using c14-morphine. materials and methods: in this study (experimental), female wistar rats (weights: 170-200 g) were mated with male rats and th...

Tissue vascularization entails the formation of a blood vessel plexus, which remodels into arteries and veins. Here we show, by using time-lapse imaging of zebrafish fin regeneration and genetic lineage tracing of endothelial cells in the mouse retina, that vein-derived endothelial tip cells contribute to emerging arteries. Our movies uncover that arterial-fated tip cells change migration direc...

Well-known as one of the main sources of cerebrospinal fluid (CSF), the choroid plexuses have been, and still remain, a relatively understudied tissue in neuroscience. The choroid plexus and CSF (along with the blood-brain barrier proper) are recognized to provide a robust protective effort for the brain: a physical barrier to impede entrance of toxic metabolites to the brain; a "biochemical" b...

Mucosal blood supply in the rat small intestine was studied by the injection replica scanning electron microscope method. The blood vascular plexus in the villus is originated at the tip of the villus and confluenced near the base of the villus. This supports the classical "fountain pattern" of MALL in the villous microcirculation. The capillary plexus in the crypt is derived at the base of the...

OBJECTIVE Choroid plexus carcinomas are rare and occur more frequently in children than in adults. The differential diagnosis includes choroid plexus papilloma and papillary ependymoma. The prognosis is generally poor. The objective of this paper is to discuss the epidemiological characteristics, diagnosis, treatment, and prognosis of this rare childhood tumor. CASE REPORT A three-year-old ch...

Epiplexus cells are a population of innate immune cells in the choroid plexus of the brain ventricles. They are thought to contribute to the immune component of the blood-cerebrospinal-fluid-barrier (BCSFB). Here we have developed a novel technique for studying epiplexus cells in acutely isolated, live and intact choroid plexus. We show that epiplexus cells are potently activated by exogenous A...

The p73 proteins are present in different kinds of cells of the central nervous system, such as the choroid plexus, circumventricular structures and neuroepithelium. It has been reported that spontaneously hypertensive rats show ventricular dilation, changes in cerebrospinal fluid proteins and variations in the circumventricular structures such as the organum vasculosum of the lamina terminalis...

Scanning electron microscope study was carried out on the methyl methacrylate cast of the intrahepatic blood vessels of the monkey and it was unequivocally demonstrated that the peribiliary blood vascular plexus received the afferent vessels from the hepatic artery and emitted the efferent vessels directly draining into the hepatic sinusoids. The possible significance of this vascular route, wh...
