OBJECTIVE To explore the effect of ginkgo leaf extract (GLE) on vascular endothelial function (VEF) in patients with early stage diabetic nephropathy (DN). METHODS Sixty-four patients were randomized equally by a randomzing digital table into two groups, the treated group and the control group. They were all treated for 8 weeks with conventional therapy(More)
STUDY OBJECTIVE To test the hypothesis that electrical burns of the genital tract and urethral strictures after hysteroscopic endometrial ablation and transurethral prostatectomy, respectively, are related to capacitive coupling and/or stray currents induced by intact and defective electrodes and/or resectoscopes. DESIGN Basic in vitro measurements. (More)
The number and variety of devices currently available for endoscopic lithotripsy reflect the reality that no single device is ideal in all situations. Although the search for the universal lithotriptor continues, the urologist must consider several factors if faced with the decision of which device to purchase. Perhaps foremost among these factors is the(More)
The aim of this study is to evaluate the influence of Tooth Mousse (TM) application, smear layer removal, and storage time on resin-dentin microtensile bond strength (µTBS). Dentin specimens were divided into two groups: (1) smear layer covered; (2) smear layer removed using 15% EDTA for 90 s. In each group, half the specimens were treated once with TM for(More)
Paeonia obovata Maxim. is a herbaceous plant in the peony family Paeoniaceae. It is mainly distributed in many parts of the world, such as the Russian Far East, Northeast China, North Korea, and Japan. Paeonia obovata has alternate and pinnately compound leaves on stout stems. Paeonia obovata flowers are pink borne in spring, emitting a strong(More)
PURPOSE This study was designed to define the pattern and significance of stray currents induced by two electrosurgical generators (ESGs) in relation to urethral strictures forming after transurethral resection of the prostate (TURP). MATERIALS AND METHODS A 24F resectoscope irrigated with glycine was activated at various power outputs in different modes,(More)
In the present paper, the authors discuss the locking phenomenon of the finite element method for three-dimensional elasticity as the Lamé constant λ → ∞. Three kinds of finite elements are proposed and analyzed to approximate the three-dimensional elasticity with pure displacement boundary condition. Optimal order error estimates which are uniform with(More)
BACKGROUND AND PURPOSE One of the most common complications of transurethral resection is urethral stricture. The exact etiology is still controversial. Postulated pathophysiology ranges from mechanical trauma to the urethra during the resection to inflammatory reaction secondary to local anesthesia. We propose electrical burn to the urethra as a(More)
