PURPOSE Dimethyl sulfoxide (DMSO) is used in a 50% solution to treat interstitial cystitis. Symptomatic relief occurs in about two-thirds of cases. The mechanism of action and effects of DMSO on bladder tissue function are poorly understood. Therefore, the effect of DMSO on bladder muscle compliance and contractility was evaluated.

The purpose of this study was to evaluate clinical, microbiological, and gingival crevicular fluid (GCF) profiles in periodontitis-resistant and periodontitis-susceptible subjects during 4 weeks of experimental gingivitis. Experimental groups of similar ages were defined as gingivitis controls (GC; n = 10) and history of rapidly progressive periodontitis(More)
OBJECTIVES To determine whether impaired reactivity to dilatory agonists could contribute to pulmonary hypertension, and whether there are gender differences in pulmonary vasodilator reactivity. METHODS Pulmonary arterial rings from monocrotaline (MCT)-induced pulmonary hypertensive and control rats were isolated. At the peaks of submaximal contractions(More)
OBJECTIVES To determine: 1) whether ovariectomy increases low-density lipoprotein (LDL) cholesterol; 2) if increased LDL cholesterol correlates with increased blood pressure; and 3) whether arterial muscle reactivity to the vasoactive oxidant hydrogen peroxide (H2O2) is gender-dependent in spontaneously hypertensive rats (SHR) and normotensive Wistar-Kyoto(More)
Oxidized low-density lipoprotein cholesterol (OX-LDL), a reactive oxidant, forms when reactive oxygen species interact with LDL. Elevated OX-LDL may contribute to high blood pressure associated with diseases such as diabetes and obesity. The current study objective was to determine if OX-LDL is a vasoconstrictor acting through the OX-LDL receptor (LOX1) on(More)
OBJECTIVE To determine the benefit of screening patients with pelvic ultrasound before commencing treatment with in vitro fertilization or gamete intra-fallopian transfer, as well as before each subsequent treatment cycle was performed. SUBJECTS AND SETTING Seven hundred and seventy-nine patients who were enrolled in the Royal Hospital for Women Fertility(More)
Electrophysiologic response characteristics of mouse sciatic nerve and spinal cord were investigated following CNS infection with the temperature-sensitive (ts) vesicular stomatitis virus (VSV) mutant G31 KS5. Measurements were obtained before clinical symptoms of the virus-induced CNS disease appeared. Sciatic nerve peak conduction velocities were not(More)
