Evaluation of Nanonanoliposomal Curcumin on Cutaneous Leishmaniasis Skin Lesions Caused by r in BALB/c Mice.

BACKGROUND

Curcumin is an extract of rhizome turmeric (diferuloylmethane), with antioxidant, anti-inflammatory, antimicrobial, and anti-parasitic properties, which making it a potential candidate for the treatment of leishmaniasis. The aim of the presented study was to evaluate curcumin as possible candidate for treatment of cutaneous leishmaniasis.

METHODS

We investigated the physicochemical properties and anti-leishmanial effects of nanoliposomal curcumin (40, 80, and 120 μM) in (MRHO/IR/75/ER) infected BALB/c mice at the faculty of Veterinary Medicinem University of Tehran, Iran. For this aim, promastigotes (MHROM/IR/75/ER) at stationary phase (2×106) were inoculated sub-cutaneously into the upper area of the tail in BALB/c mice (six groups, n= 10 per group). For evaluation of nanoliposomal curcumin, the zeta potential, particle size and stability of nanoliposomal curcumin was determined. Furthermore, the anti-leishmanial effects of nanoliposomal curcumin formulation on the lesion sizes was determined and the parasite burden in the leishmania induced lesion was performed using semi quantitative PCR.

RESULTS

Treatment of infected BALB/c mice with nanoliposomal curcumin led to a reduction in the kinetic of the skin lesion size development. The semi quantitative PCR analysis of DNA extracted from the lesions showed reduction of parasite burden. The most effective treatment could be found in 80 μM nanoliposomal curcumin. Treatment with Glucantime, as a positive control, also showed a nearly similar effect compared to the effect of 80 μM nanoliposomal curcumin.

CONCLUSION

Nanoliposomal curcumin could be considered as a potential drug against cutaneous leishmaniasis caused by in susceptible animal models.
