The antihypertensive effect of crude stevioside obtained from the leaves of Stevia rebaudiana (Bertoni) Bertoni (Compositae) on previously untreated mild hypertensive patients was examined. Patients with essential hypertension were submitted to a placebo phase for 4 weeks. The volunteers selected in this phase were randomly assigned to receive either(More)
The purpose of the present work was to investigate the influence of celecoxib on some hepatic metabolic parameters affected by the Walker-256 tumour in rats. Celecoxib was administered daily (5-50 mg/kg body weight) beginning at the day in which the tumour cells were inocculated. At day 14, the liver was isolated and perfused in order to measure alanine(More)
Vulvovaginal candidiasis (VVC) is regarded as an important public health issue, and several aspects of its pathogenesis are not yet sufficiently clear. Experimental in vivo models of vaginal infection with Candida albicans have been extremely useful in the identification of factors concerning hormonal influences on the infection, the virulence of the(More)
BACKGROUND Study of in vivo antifungal activity of the hydroalcoholic extract (HE) and n-BuOH extract (BUTE) of Sapindus saponaria against azole-susceptible and -resistant human vaginal Candida spp. METHODS The in vitro antifungal activity of HE, BUTE, fluconazole (FLU), and itraconazole (ITRA) was determined by the broth microdilution method. We obtained(More)
An extract from seeds of Chenopodium quinoa Willd. (quinoa), termed hydrolyzed quinoa (HQ), was obtained by enzymatic hydrolysis from seeds of the quinoa variety BRS-Piabiru. Analysis of the physical and chemical properties of quinoa and HQ showed that the hydrolyzed extract is rich in essential amino acids, particularly those with branched chains (leucine,(More)
AIM To study the influence of the course of diabetes, aging, and glycemia on the sorbitol accumulation in diabetic rats. METHODS Streptozocin (Str) diabetic rats were obtained by Str i.v. (35 mg.kg-1). Glycemia and sorbitol levels from sciatic nerve and lens were measured after 1 d, 2, 5, and 8 months of diabetes. Sorbitol concentrations in serum, heart,(More)
We evaluated the effect of chronic (3 wk) subcutaneous treatment with progesterone and estradiol (PE; producing serum levels observed in the 3rd trimester of pregnancy) or placebo (C) on hepatic and whole body insulin sensitivity and response to hypoglycemia in conscious, overnight-fasted nonpregnant female dogs, using tracer and arteriovenous difference(More)
AIM The contribution of insulin resistance (IR) and glucose tolerance to the maintenance of blood glucose levels in non diabetic pregnant Wistar rats (PWR) was investigated. MAIN METHODS PWR were submitted to conventional insulin tolerance test (ITT) and glucose tolerance test (GTT) using blood sample collected 0, 10 and 60 min after intraperitoneal(More)
Although most recent publications focus on Ventilator-associated Pneumonia, Non-Ventilator-associated Hospital-acquired pneumonia (NVHAP) is still worrisome. We studied risk factors for NVHAP among patients admitted to a small teaching hospital. Sixty-six NVHAP case patients and 66 controls admitted to the hospital from November 2005 through November 2006(More)
OBJECTIVE The purpose of this study was to develop an experimental model of diabetes in female rats and verify its influence on vulvovaginal candidiasis. STUDY DESIGN The animals were divided into control and diabetic groups. Diabetes was induced with the use of an intravenous solution of alloxan (42 mg/kg bodyweight). One week after confirmation of(More)
