The use of different interpretative criteria
for E. coli responsible for UTIs therefore has no influence on the decision to be taken by the physicians managing the patients.”
“The aim of this study was to investigate the effects of Bersama engleriana and its potential mechanism on fictive ejaculation in spinal male rats. The electromyographic activities of the bulbospongiosus muscles were recorded in spinal cord transected and urethane-anesthetized rats treated intravenously with aqueous (100 mg kg(-1)) and methanolic (100 mg kg(-1)) extracts from the dried leaves of B. engleriana in the absence and presence of dopamine (0.1 mu mol kg-1) or oxytocin (0.5 UI kg(-1)). Mechanical stimulations of the urethra were also carried out 5 min after the sequential treatments. A single intravenous see more administration of aqueous (100 mg kg(-1)) and methanolic (100 mg kg(-1)) extracts of B. engleriana did
not activate fictive ejaculation. The electromyography Selleckchem SB203580 recorded after the application of the plant extract was similar to that obtained after intravenous saline injection (200 Gl min(-1)) with no contraction of the bulbospongiosus muscles. Dopamine (0.1 mu mol kg(-1)) and oxytocin (0.5 UI kg(-1)) induced rapid rhythmic contractions (P < 0.001) of the bulbospongiosus muscles accompanied by penile erection and sometimes with expulsion of the seminal plugs. Pretreatment of rats with the two plant extracts completely abolished the occurrence of ejaculation induced by dopamine (0.1 mu mol kg(-1)) and oxytocin (0.5 UI kg(-1)). Mechanical stimulation of the urethra carried out 5 min after the sequential treatments always induced penile movements and erections. The inhibitory effect of B. engleriana extracts on CCI-779 in vitro the expression of fictive ejaculation in spinal male rat is mediated through dopaminergic and oxytocinergic pathways. This prolonged ejaculatory latency caused by B. engleriana could support its potential use in patients with rapid ejaculation.”
“Study Design. Review the presentation
and diagnosis of a lumbar intradural varix.
Objective. To report an innovative magnetic resonance imaging (MRI) technique that enabled radiographic diagnosis in a rare case of symptomatic lumbar intradural varix.
Summary of Background Data. Lumbar variceal veins rarely occur intradurally, and may radiographically mimic nerve-sheath tumors. These lesions are typically diagnosed at surgery performed due to suspicion of tumor.
Methods. A 55-year-old man presented with radicular lower back pain and normal neurologic examination. MRI revealed an ellipsoid intradural enhancing mass at the L2 level. The patient refused to undergo the surgical procedure that was recommended. Over 2-year follow-up, symptoms resolved together with weight reduction. Repeat MRI revealed an unchanged lumbar lesion in addition to engorged epidural and intradural veins, thought to be related to outflow obstruction secondary to past right nephrectomy and obliterated inferior vena cava.
