PURPOSE The aim of this study was to assess the pharmacophysiological significance of the enteric nervous system for the mechanical responses of lower esophageal sphincter (LES) in infantile rats with kaolin-induced hydrocephalus. MATERIAL AND METHODS Hydrocephalus was created in 7-day-old rats by injection of kaolin into the cisterna magna. After 10 days, rats were decapitated. Contractile (...

Raman, IR, and surface-enhanced Raman scattering (SERS) were employed for the vibrational characterization of papaverine in the free and adsorbed state. The vibrational assignments were performed by means of density functional theory (DFT) calculations. The adsorption of the molecule was concluded with the isoquinoline and the benzene ring close to the silver surface in tilted orientations. Emp...

This study details our initial experience with pharmacologically induced penile erections in the diagnosis and therapy of patients with impotence. Intracavernosal injections of papaverine were performed in 5 normal volunteers, 5 patients with psychogenic impotence and 2 patients with penile venous incompetence. The patients were first investigated extensively to determine the etiological basis ...

The inhibitor constants of several inhibitors for cyclic AMP- and cyclic GMP-phosphodiesterase from various organs are compared. The inhibitors were classical theophyline, papaverine, and some of newly developed inhibitors: an imidazolidinone compound, RO20-1724, and two phthalazinol compounds, EG 467 and EG 626. Among the inhibitors tested, papaverine and EG 626 were found to be the most poten...

Cerebral vasospasm and delayed cerebral ischemia account for significant morbidity and mortality after aneurysmal subarachnoid hemorrhage. While most patients are managed with triple-H therapy, endovascular treatments have been used when triple-H treatment cannot be used or is ineffective. An electronic literature search was conducted to identify English language articles published through Octo...

Once an adrenal origin has been excluded the treatments available for PCO are temporary or symptomatic. Clomiphene can only be used short term under well-controlled conditions in women who want to have children. Anti-androgens can suppress hirsutism but their long-term effects are unknown and they do have to be taken continuously. Only wedge excision of both ovaries permits a full resumption of...

BACKGROUND There is a great deal of medical literature suggesting that substance use disorder is a serious clinical concern, affecting general population and associated with considerable economic, societal, and personal costs. OBJECTIVES This study sought to clarify the relationship between early trauma, dissociative experience, and suicide ideation as predictive factors of active and passive...

In the penis, nitric oxide (NO) can be formed by both neuronal NO synthase and endothelial NOS (eNOS). eNOS is activated by viscous drag/shear stress in blood vessels to produce NO continuously, a process mediated by the phosphatidylinositol 3-kinase (PI3kinase)/Akt pathway. Here we show that PI3-kinase/Akt physiologically mediates erection. Both electrical stimulation of the cavernous nerve an...

Embolic acute mesenteric ischemia (EAMI) is an uncommon abdominal emergency, but is associated with a high mortality rate. It results from sudden interruption to intestinal blood flow and leads to bowel infarction. Early diagnosis and treatment with prompt laparotomy and embolectomy is the standard treatment. There are reports using percutaneous catheter-based thrombolytic and mechanical clot e...

A high-resolution infrared (IR) camera was used to assess rhythmicity in localized renal blood flow, including the extent of regions containing nephrons with spontaneous oscillations in their individual blood flow. The IR imaging was able to follow changes in rat renal perfusion during baseline conditions, during occlusion of the main renal artery and during the administration of either saline ...
