Purpose: To develop a highly accurate molecular assay for evaluating the efficacy of metronidazole and some antifungal agents with meglumine antimoniate against L. infantum visceral leishmaniasis in different mouse tissues. Methods: The assay was performed with the Light-Cycler system using SYBR Green I and primers amplifying ca. 120-bp fragment from minicircles of the kinetoplast DNA (kDNA).Th...

Cutaneous leishmaniasis and HIV coinfection has been reported in Brazil since the initial description of AIDS in the country. We report an HIV-positive patient under antiretroviral treatment who presented with cutaneous leishmaniasis which was successfully treated with meglumine antimoniate.

AIM To evaluate the minimal iodine contrast medium load necessary for an optimal computed tomography colonography tagging quality. MATERIALS AND METHODS Faecal occult blood test positive patients were randomly selected for one of three iodine bowel preparations: (1) 3 × 50 ml meglumine ioxithalamate (45 g iodine), (2) 4 × 25 ml meglumine ioxithalamate (30 g iodine); or (3) 3 × 25 ml (22.5 g i...

The standard treatment of human visceral leishmaniasis involves the use of pentavalent antimony (SbV) compounds. In recent years increasing numbers of clinical failures of treatment with SbV have been reported, probably due to the development of parasite resistance to this compound. The mode of action and mechanisms of resistance to SbV have not been fully elucidated. In the present study an ax...

OBJECTIVES The aim of this study was to evaluate Gd retention in the deep cerebellar nuclei (DCN) of linear gadolinium-based contrast agents (GBCAs) compared with a macrocyclic contrast agent. MATERIALS AND METHODS The brain tissue retention of Gd of 3 linear GBCAs (gadobenate dimeglumine, gadopentetate dimeglumine, and gadodiamide) and a macrocyclic GBCA (gadoterate meglumine) was compared i...

The pentavalent antimonies, mainly the meglumine antimoniate, are recommends as first-choice medicines for leishmaniasis therapy. In this work we described the development of formulations of meglumine antimoniate injectable medication, as well as the analytical methodology used in the selective determination of Sb(III) and Sb(Total) by hydride generation - inductively coupled plasma atomic emis...

lead antimonate yellow and lead-tin-antimony yellow) have been produced, starting from various recipes and from pure chemicals, in different experimental conditions. The products were analysed using micro-Raman spectroscopy. Differences in stoichiometric ratios, in melting temperatures and in crucible typologies were examined. Other analytical techniques were required to characterize the stoich...

The most common agent used for infusion therapy in patients with diabetic ketoacidosis (DKA) is isotonic 0.9% sodium chloride solution. However, of required volumes can result development iatrogenic complications — i. e., worsening metabolic hyperchloremic acidosis DKA already altered acid-base balance. Balanced crystalloid solutions be as alternative to saline. Objective. To evaluate the feasi...
