BACKGROUND/AIMS Enterocutaneous fistulas are associated with prolonged hospital stay, high morbidity/mortality, and increased hospital costs. This study aims to describe the use of a vacuum system and normal oral diet in dealing with this problem. METHODS Seventy-four consecutive patients with recent and defined external postoperative fistulas were(More)
PURPOSE Statins are widely recognized as hypolipemic drugs, but some studies have observed anti-inflammatory and immunomodulatory effects, known as pleiotropic. The aims of this work was to study possible anti-inflammatory effects of simvastatin in abdominal sepsis. Serum pro-inflammatory cytokines and leukocytes count were determined in an experimental(More)
Topical treatment of cutaneous leishmaniasis represents an exciting alternative for reducing toxicity associated with parenteral administration of conventional amphotericin B. This work aims to develop and to characterize amphotericin B-loaded new carriers and to investigate their potential for topical delivery by conducting permeation studies with pig ear(More)
Carapa guianensis, a popular medicinal plant known as “Andiroba” in Brazil, has been used in traditional medicine as an insect repellent and anti-inflammatory product. Additionally, this seed oil has been reported in the literature as a repellent against Aedes aegypti. The aim of this work is to report on the emulsification of vegetable oils such as(More)
PURPOSE Amphotericin B (AmB), an antifungal agent that presents a broad spectrum of activity, remains the gold standard in the antifungal therapy. However, sometimes the high level of toxicity forbids its clinical use. The aim of this work was to evaluate and compare the efficacy and toxicity in vitro of Fungizon (AmB-D) and two new different AmB(More)
Structure and viscoelastic properties of negatively charged oil-in-water (o/w) microemulsions have been investigated. Microemulsions (ME) containing soya phosphatidylcholine (SPC), eumulgin HRE 40 (EU) and sodium oleate (SO) as surfactant, cholesterol (CHO) as oil phase, and aqueous buffer with and without the antitumoral doxorubicin (DOX) have been(More)
In this work the structural features of microemulsions (MEs) containing the pharmaceutical biocompatible Soya phosphatidylcholine/Tween 20 (1:1) as surfactant (S), Captex 200 as oil phase (O), and phosphate buffer 10mM, pH 7.2 as aqueous phase (W) were studied. Systems obtained with different proportions of the components were described by pseudo-ternary(More)
Although many authors have reported several beneficial effects ascribed to xylan, such as inhibitory action on mutagenicity activity, antiphlogistic effects, and mitogenic and comitogenic activities, few papers have investigated a systematic study on the technological properties of this polymer. The aim of the present work was to evaluate xylan as a promise(More)
This study evaluated the effects of total colectomy on the biodistribution of technetium-99m pertechnetate ((99m)TcO(4)(-)) on the 28th postoperative day in rats. Samples of several organs were harvested for counting the percent of injected radioactivity/g of tissue (%ATI/g). The %ATI/g in colectomy rats was higher in the stomach and ileum than in sham and(More)
PURPOSE This study explores the potential of the simvastatin to ameliorate inflammation and infection in open infected skin wounds of rats. METHODS Fourteen Wistar rats weighing 285 +/- 12g were used. The study was done in a group whose open infected skin wounds were treated with topical application of simvastatin microemulsion (SIM, n=7) and a second(More)
