Abstract

Background: Cutaneous leishmaniasis is a health problem in the world. Lesions should be treated on cosmetically or functionally important sites, such as the face and hands. Cantharidin is a terpenoid compound produced naturally by beetles of Meloidae and Oedemeridae families. Objectives: The current study aimed to investigate the effect of cantharidin on Cutaneous Leishmaniasis (CL) lesions and IFN-gamma and IL-4 patterns in infected BALB/c mice. Materials and Methods: Infected BALB/c mice were divided into five groups as: untreated (control group), eucerin-treated and 0.05, 0.1 and 0.5 cantharidin-treated. Lesions diameter was measured by Vernier caliper every three days for four weeks. Cytokines levels were measured by enzyme-linked immunosorbent assay (ELISA) using U-CyTech kit. Results: The results indicated that treatment with cantharidin exacerbates lesions compared with the controls, except for 0.05 cantharidin dose that restrained lesion growth significantly. Interferon gamma level in cantharidin-treated groups was significantly less than that of the control group. But interlukin-4 level was similar among the groups. Conclusions: The current study results indicated that high doses of cantharidin exacerbates leishmaniasis lesion, but low dose of cantharidin inhibits lesion growth.
