Abstract
Therapeutic research is very important in the prevention and treatment of leishmaniasis due to problems such as drug resistance, scarring and disease recurrence. The aim of this study was to determine how Leishmania major responds to the anti-leishmaniasis properties of podophyllotoxin and podophyllin. Cultured Leishmania promastigotes were exposed to different concentrations of podophyllotoxin and podophyllin for 24 and 48 h. Then, during the animal phase, Balb/c mice were experimentally injected with Leishmania promastigotes. After wounding, the effects of 0.5% podophyllotoxin and 25% podophyllin on reducing wound diameter and the number of amastigotes in the wound were evaluated. Podophyllotoxin and podophyllin were 83% and 59% lethal to Leishmania major promastigotes at the highest concentrations (200 µg/ml) and time (48 h). In the in vivo study, the mean lesion diameter at the end of treatment in the negative control group was 15.10 mm compared to 14.21 mm and 11.55 mm in the 25% podophyllin and 0.5% podophyllotoxin groups, respectively. Although both agents reduced the size of mice wounds and the number of amastigotes in the wounds, podophyllotoxin was more effective in this regard. Based on the results, podophyllotoxin and podophyllin can be used as leishmaniasis drugs after further research.
期刊介绍:
The primary constituency of the Journal of Parasitic Diseases is parasitology. It publishes original research papers (pure, applied and clinical), which contribute significantly to any area of parasitology. Research papers on various aspects of cellular and molecular parasitology are welcome.
