Treatment of cutaneous leishmaniasis in murine model by hydro alcoholic essence of Artemisia sieberi

Considering the prevalence of leishmaniasis in Iran and many side effects associated with pentavalent antimony compounds use in its treatment, this study was designed to evaluate the effect of Artemisia sieberi essence on the experimental ulcers of cutaneous leishmaniasis on BALB/c mice. This experimental research was performed to determine the effect of various concentrations of Artemisia essence in BALB/c mice previously infected with active Leishmania major promastigote. A total of 50 infected BALB/c mice were randomly divided into 5 groups. Three groups [30 mice] were used in the experimental conditions and the others were assigned as the control groups. The experimental groups received 1%, 3% and 5% of Artemisia, respectively. One of the control groups received ethanol 80% and the other received no treatment. The drug was administered by dropping the liquid on the top lesions, three times daily for maximum of 30 d. Every 10 days the ulcers diameter were measured and sampled for amastigote in all groups. Ulcers diameter changes were determined by statistical tests. After 30 days, diameter of CL lesions increased in 1%, 3% and 5% Artemisia concentrations and the control groups. Ulcers got bigger with the more concentration. Treatments could not reduce the diameter or caused small lesions. In addition, the mice direct smears in microscopic studies were positive. To find the effective concentration and the mechanism of the effectiveness of the drug, further investigations with less concentrates of A. sieberi essence are recommended
