BACKGROUND This study compared histological and immunohistochemical changes of cutaneous leishmaniasis treated with meglumine antimoniate, imiquimod, and the combination of both therapies. METHODS Single blind clinicopathological studies of fifteen patients with old world cutaneous leishmaniasis in Kerman, Iran were included. A total of four patients received a combination of imiquimod (5% cr...

Treatment of cutaneous leishmaniasis is often difficult. Even though most cutaneous lesions will heal spontaneously, their duration cannot be predicted in an individual case. In general, only large, multiple or diffuse lesions of the face, head and neck need to be considered for therapeutic intervention. Pentavalent antimonials (sodium stibogluconate and meglumine antimoniate) administered intr...

Potassium pyroantimonate was used to localize sites of bound cations in human neutrophils under conditions of random migration, stimulated random migration (chemokinesis), and directed migration (chemotaxis). The cells were placed in a standard chamber in which 0.45-micron micropore filters separated the cells from the stimulus (buffer, Escherichia coli endotoxin-activated serum or the syntheti...

INTRODUCTION Pentavalent antimonials are the first drug of choice in the treatment of tegumentary leishmaniasis. Data on ototoxicity related with such drugs is scarcely available in literature, leading us to develop a study on cochleovestibular functions. CASE REPORT A case of a tegumentary leishmaniasis patient, a 78-year-old man who presented a substantial increase in auditory threshold wit...

OBJECTIVE To explore the knowledge, beliefs, and practices (KBPs) regarding cutaneous leishmaniasis (CL) treatment held by an endemic population in Ecuador. METHODS A follow-up to research done several years before, this study used random cluster sampling to select 529 adults who lived in rural northwestern Ecuador. Data were collected over a 24-month period using in-depth interviews suppleme...

In the immunocompetent host, visceral leishmaniasis (VL) is a fatal disease if untreated. In immunosuppressed patients, VL is an opportunistic infection for which there is no effective treatment for relapses. Here we report on the long-term activity of orally administered hexadecylphosphocholine (HDPC) against established Leishmania infantum infection in BALB/c mice. HDPC is a synthetic phospho...

Effects of different doses of dexamethasone plus flunixin meglumine on survival rate were investigated in lethal endotoxemia. A total of 60 Balb/C female mice were divided into 4 equal groups. Lethal endotoxemia (80-100%) was induced by lipopolysaccharide injection (Group 1, 1 mg, intraperinoneally). At 4 hours after the lipopolysaccharide injection; low-dose dexamethasone (0.6 mg/kg, SID, 5 da...

PURPOSE To compare enhancement characteristics and image quality of two macrocyclic gadolinium chelates, gadoterate meglumine and gadobutrol, in low-dose, time-resolved MRA of the calf station. MATERIALS AND METHODS 100 consecutive patients with peripheral arterial disease (stages II-IV) were retrospectively analysed. Fifty patients were included in each group - 32 men and 18 women for gadobu...

The pyroantimonate technique was employed to identify the binding sites for calcium in unfertilized Arbacia punctulata and Strongylocentrotus purpuratus eggs. Since antimony is non-specific and binds with a variety of cations, the indentification of calcium was established by specific chelation with ethyleneglycol tetra-acetic acid (EGTA) and X-ray microprobe analysis. Antimony deposits were ob...
