Treatment of Cutaneous Leishmaniasis in Murine Model by Alcoholic Extract of Berberis vulgaris

In order to evaluate the effect of berberis vulgaris extract on the experimental ulcers of cutaneous leishmaniasis (cl) on balblc mice, a study was undertaken over a 12 months period. forty balblc mice were divided into 2 main groups a and b. each main group in turn was divided into 5 sub groups of 4 mice and each sub group were inoculated subcutaneously by o.lmi liquid phase culture containing promastigotes of leishmania major. after 2-3 weeks, nodules and ulcers appeared on 37 of 40 inoculated mice. ethanol extract of the stem and leaves as well as roots of berberis vulgaris in different concentrations, were used topically on cl lesions of 4 sub groups a and b, respectively. ethanol alone was used on the lesions of control mice. the surface area of lesions were measured before and 1-2 weeks after treatment. direct geimsa stained smear prepared 20 days after treatment. the results showed that after 2 weeks, a statistically significant decrease of ulcer size of treated mice observed, while in the control group the lesion growth continued. the examinations showed that using higher concentration of the extract caused more decrease in surface area of cl lesions on day 15 andnegative direct smear on day 20. alcoholic extract of b.vulgaris root was more effective than leaves and stem extract. alcoholic extract ofb vulgaris might be further used in animal model.
