The following diagram shows how an erection is mediated and how sildenafil acts in the body. Nitric Oxide (NO) is released with sexual stimulation from nerve endings and endothelial cells in the spongy erectile tissue, the corpus cavernosum of the penis. The enzyme guanylate cyclase then converts guanosine triphosphate (GTP) into cyclic guanosine monophosphate (cGMP). cGMP causes the smooth muscle to relax, which causes an inflow of blood which then leads to an erection. cGMP is then hydrolysed back to the inactive GMP by phosphodiesteras type 5 (PDE5). The levels of cGMP are therefore controlled by the activation of cyclic nucleotide cyclase and the breakdown by PDE5. It is the latter that sildenafil acts upon. Men who suffer from erectile dysfunction often produce too little amounts of NO. This means that the small amount of cGMP they produce is broken down at the same rate and therefore doesnt have the time to accumulate and cause a prolonged vasodilation effect. Sildenafil works by inhibiting the enzyme PDE5 by occupying its active site.
This means that cGMP is not hydrolysed as fast and this allows the smooth muscle to relax. Sildenafil is a potent and highly selective inhibitor of PDE5. If viewed in cross section, the glans of the penis reveal that the penis consists of three tube-like projections of spongy tissue, the corpus spongiosum, located ventrally and the paired corpi cavernosi located dorsally. In each of the latter is the deep artery of the penis which carries blood over the length of the penis into the open channels that make up the corpus cavernosum.
The blood carried out of the corpi cavernosi empties into the dorsal vein of the penis which then returns the blood to the body. It is thought that the level of rigidity of the penis is due to the relationship between arterial inflow and venous outflow in the penis. This means that the larger the calibre of the arteries, the more blood enters the corpus cavernosum and enlarges the penis, and the larger the calibre of the veins, the more blood is shunted away from the penis. An erection is an involuntary action controlled by the autonomic nervous system which consists of the sympathetic and parasympathetic pathways. In general, sympathetic stimulation leads to the constriction of smooth muscle surrounding the arteries (reducing the calibre) and parasympathetic stimulation induces smooth muscle relaxation (larger artery). When stimulated sexually, the sympathetic stimulation of the penis decreases and the parasympathetic stimulation increases. It is the terminal of the axons of the parasympathetic nerves that release NO. The mechanism that causes erection is then the one shown above.
The ened sinusoids of the corpi cavernosipress the penile veins, which reduces blood outflow from the penis. Blood is therefore trapped in the penis, which maintains the erection. The cycle of transformations of guanosine triphosphate is shown in more detail below (GC-Guanosine cyclase): Sidenafil is selective for the enzyme phosphodiesterase of type 5. its effect is more potent on PDE5 than on the other known PDE enzymes. It is 80-fold more selective for PDE5 than PDE1 and over 1000-fold more selective for PDE5 than for PDE2, PDE3 and PDE4. However, its selectively is only 10-fold as potent for PDE5pared to PDE6 (found in the retina) which could be the basis for abnormalities related to colour vision (blue, green) which have been talked about a lot in the media. PDE5 is also found in lower concentrations in the platelets, vascular and visceral smooth muscle and skeletal muscle. Sildenafil inhibits PDE5 in these tissues as well, which is the cause of several side effects which are believed to be due to Viagra.
There are 7 types of phosphodiesterases (or isozymes). They catalyse the same reaction, but the isozymes show show different behaviour when subjected to physical biochemical techniques. Those 7 types of PDE are summerised in the table below. The Km values are equivalent to measurements of the tightness of binding (or affinity) of enzyme (PDE) to substrate (cGMP).
The smaller the Km value, the more tightly the substrate binds to the enzyme. Objectives Sildenafil citrate, a specific phosphodiesterase-5 inhibitor, is increasingly used for pulmonary hypertension in pregnancy. Sildenafil is also emerging as a potential candidate for the treatment of intra-uterine growth retardation and for premature labor. Its effects in the feto-placental circulation are not known.
Our objectives were to determine whether phosphodiesterase-5 is present in the human feto-placental circulation, and to characterize the effects and mechanisms of action of sildenafil citrate in this circulation. Study Design Ex vivo human chorionic plate arterial rings were used in all experiments. The presence of phosphodiesterase-5 in the feto-placental circulation was determined by western blotting and immunohistochemical staining. In a subsequent series of pharmacologic studies, the effects of sildenafil citrate in pre-constricted chorionic plate arterial rings were determined. Additional studies examined the role of cGMP and nitric oxide in mediating the effects of sildenafil. Conclusion Phosphodiesterase-5 is present in the feto-placental circulation.
Sildenafil citrate vasodilates the feto-placental circulation via a cGMP dependent mechanism involving increased responsiveness to NO. Background Sildenafil citrate, a specific phosphodiesterase-5 inhibitor, has demonstrated considerable promise as a pulmonary vasodilator 1 -4 . Sildenafil has been proposed as a potentially useful therapy for pulmonary hypertension in pregnancy, a disease characterized by poor maternal and fetal oue 5 ,6 . Several case reports of its use in pregnant patients with pulmonary hypertension have been published to date 7 ,8 . The effects of sildenafil citrate on the pulmonary vasculature and on pulmonary artery pressure are increasingly well understood. Sildenafil citrate acts by reducing cGMP breakdown, making pulmonary vascular smooth muscle more sensitive to both endogenous and exogenous NO, reducing ventilation/perfusion mismatch and hypoxia 1 ,9 ,10 . Sildenafil is also emerging as a potential candidate for the treatment of intra-uterine growth retardation and for premature labor 11 . Sildenafil has also been proposed as a potential therapeutic strategy to maintain placental function in pre-eclampsia 12 . While placental transfer of sildenafil citrate has not been quantified, due to its chemical characteristics it is likely to easily cross the placenta into the fetus. Should sildenafil citrate possess vasodilatory effects in the feto-placental circulation, this would significantly enhance its therapeutic potential in the setting of placental insufficiency. Of interest, sildenafil citrate has recently been demonstrated not to alter the contractile response to vasoconstrictors or to endothelial dependent vasodilators13 . However, the direct effects of sildenafil citrate in the feto-placental circulation have not been determined. The purposes of these studies were to determine whether the phosphodiesterase-5 enzyme was present in the feto-placental circulation, and then to characterize the effects and mechanisms of action of sildenafil citrate in this circulation. Following approval by the Galway University Hospitals Clinical Research Ethicalmittee, and written informed patient consent, term placentae were obtained following both vaginal and elective cesarean delivery under regional anesthesia from patients following normal pregnancy.
None of the patients from whom the samples were taken received general anesthesia for delivery. Exclusion criteria included intra-uterine growth retardation, pre-eclampsia, and patients with pregnancy induced hypertension, hepatitis and HIV. In all studies, umbilical arteries and their branches were identified as they spread out onto the chorionic plate of the placenta. Samples of the second-generation (second-order) chorionic plate arteries were taken within 120 minutes of delivery and placed directly into ice-cold pyrogen-free physiologic saline solution (122.6 mM NaCl, 5.4 mM KCl, 20 mM NaHCO 3 . 0.8 mM MgSO 4 . 0.9 mM Na 2 HPO 4 . 2.4 mM CaCl 2 and 5.5 mM glucose) or flash frozen depending on the experimental requirements. Characterization of Phosphodiesterase-5 RT-PCR detection of Phosphodiesterase-5 mRNA Freshly dissected chorionic plate arterial rings were homogenized in Tri-Reagent (Sigma Aldrich, Poole, Dorset, United Kingdom) using a Tissuptor (Qiagen, Crawley, United Kingdom). RNA was then isolated as previously described 14 . RNA concentration was assessed using a ND-1000 Spectrophotometer (NanoDrop Technologies, Wilmington, DE USA), and 1 x003bcg used to generateplementary DNA (cDNA) using an Access RT-PCR kit (Promega UK, Southampton, United Kingdom). Polymerase chain reaction was performed on the resulting cDNA in a DNA Engine thermal cycler (Bio-Rad Laboratories, Hercules, CA, USA). Detection primers used were: Lamin A/C control: forward 5-ATGGAGACCCCGTCCCAG-3 reverse 5-AGCTATCAGGTCACCCTCCTT-3 PDE-5: forward 5-TGGTCAATGCATGGTTTGCT-3 reverse 5-TCAGTCCATGGATATGCAAGA-3 PCR products were analyzed on a 1 agarose (w/v) TAE gel and imaged using GeneSnap image acquisition software (Syngene, Cambridge, United Kingdom).
Western blot detection of Phosphodiesterase-5 Protein Freshly dissected chorionic plate arterial rings were homogenized in ice-cold PBS, at 100 mg per mL, using a Tissuptor (Qiagen). Samples were sonicated, and centrifuged at 14000 g for 5 minutes to remove insoluble proteins. SDS-PAGE sample buffer was added to various volumes of lysate and samples electrophoresed on a 4x0201320 acrylamide gel. Protein was transferred to nitrocellulose and probed using a mouse monoclonal PDE-5 antibody (Clone number H00008654-M01, Abnova, Walnut, CA, USA). Immunohistochemical demonstration of Phosphodiesterase-5 Freshly dissected chorionic plate arterial rings were snap frozen in isopentane and embedded in OCT and sectioned to 15 x003bcM thickness on glass slides as previously described 15 . Sections were permeabilized with 0.3 triton-PBS (v/v), and probed using PDE-5 primary (Abnova) and phycoeryhtrin labeled secondary (Sigma Aldrich) antibodies. Coverslips were sealed to the slides with Hardset DAPI (Vector Laboratories, Servion, Switzerland) mounting medium, and images taken under fluorescent microscopy. The coverslip was later removed and the section stained with haematoxylin and eosin to demonstrate ring scture.

Miami Office Quintairos, Prieto, Wood amp Boyer, P. A. 9300 South Dadeland Blvd. QPWB Prevails with Defense Verdict in Nursing Home Malpractice Action TAMPA, Fla. Peter J. Molinelli and Sheila K. Nicholson . trial attorneys in the Tampa office of Quintairos, Prieto, Wood Boyer, P. A. . achieved a defense verdict on behalf of a nursing home where the plaintiff alleged that the nursing home failed to provide appropriate skin care and follow physician orders, which resulted in severe heel ulcerations. The resident was 88 years old when he entered the facility and turned 89 while residing there.
He was at the facility for nine and a half weeks and alleged that a delay in the delivery of a trapeze caused him to develop pressure ulcers to his heels. These pressure ulcers required debridement and were allegedly extremely painful. In addition, the nurses failed to document 33 doses of oxycodone on the Medication Administration Records (MAR) which the plaintiff argued that the resident did not receive thus suffering from untreated pain throughout his residency. A facility investigation found there were missing narcotics for another resident. Further, one of the nurses caring for the resident failed to document 24 doses of oxycodone on the MAR. During a g screening, she tested positive for cocaine and her employment terminated immediately. However, the nurses positive test was not for any of the residents prescribed medications, nor of the missing medication that prompted the testing. Plaintiff argued that not only did the nursing home cause the pressure ulcers but also failed to treat the residents persistent pain because the nurses were diverting narcotics to support other g habits. Plaintiff even called the police officer that investigated the missing narcotic gs and solicited testimony that it wasmon for narcotics to be diverted and sold for money to support other g habits.
During the trial, the plaintiff also added that the resident suffered from untreated pain related to a prior medical condition of spinal stenosis and metastatic bone cancer in an effort to establish there had been an exacerbation of prior condition. The defense was able to prove that the resident was alert and oriented so that if he was not receiving his pain medications he could and was the type of individual that would let someone know he had pain. Further, that the delay in receipt of a trapeze bar was not the cause of the heel wounds but rather, that the heel wounds were blisters that resulted from gait training with physical therapy. Additionally, based on the records, there were only two documented occurrences when the residentplained of pain and thereafter stated he had pain relief. Lastly, the defense was able to show over 55 entries in the medical records for the nine and a half weeks residency where it was documented that the resident had no pain. Thus, it became evident that the resident had not suffered from untreated pain. This documentation included the nursing home records as well as the wound care center and hospice records. The jury delivered a defense verdict based on evidence indicating that a delay in equipment did not cause the wounds and that the resident did not suffer from untreated pain.
The jury was able to separate the issue of the treating nurse testing positive for a g that led to her employment termination. About QPWB Quintairos, Prieto, Wood Boyer, P.
