AIMS The aim of this study was to assess the impact of patient-perceived disease severity (PPDS) on the quality of life (QoL) of women with urinary incontinence (UI) and to identify factors predicting PPDS. METHODS A total of 109 women (mean age 54.9; range 31-77) with stress UI combined with or without urge UI were included in the primary analyses. The(More)
PURPOSE The effects of subphysiological and physiological levels of estradiol on vaginal blood flow and estrogen receptor were investigated. MATERIALS AND METHODS Intact or ovariectomized female Sprague-Dawley rats were used. Two weeks after surgery rats were infused with vehicle (polyethyleneglycol), or estradiol at subphysiological (5 microg daily) or(More)
Arginase is a binuclear manganese metalloenzyme that catalyzes the hydrolysis of l-arginine to form l-ornithine and urea. The X-ray crystal structure of a fully active, truncated form of human arginase II complexed with a boronic acid transition state analogue inhibitor has been determined at 2.7 A resolution. This structure is consistent with the(More)
BACKGROUND The objective of this study was to determine whether the outcome of mid-urethral sling procedures is influenced by the body mass index of Korean women suffering from stress urinary incontinence (SUI). METHODS A total of 285 women, ranging in age from 28 to 80 years (mean 55.4), all of whom were followed up for at least 6 months, were ultimately(More)

INTRODUCTION The mechanisms by which testosterone modulates female genital sexual arousal responses are poorly understood. AIM To investigate the effects of testosterone on vaginal blood flow and the expression of estrogen and androgen receptor proteins in the rat vagina. METHODS Mature female Sprague-Dawley rats were sham-operated (intact) or(More)
We investigated the effects of systemic modulation of angiotensin 2 on the erectile dysfunction of aged rats. Young and aged (18 months old) male Sprague-Dawley rats were either treated with daily administration of losartan (angiotensin type 1 receptor antagonist, 30 mg/kg/d PO) or the drug vehicle (control) for 4 weeks (n=6 in each group). We monitored the(More)
