Background an objective: Leishmaniasis is a common disease endemic in some parts of Iran. Chemical or physical treatments or a combination of both are used for treatment of the disease. Nitric oxide (NO) is important for healing of leishmaniasis in human and animal. This study was designed to evaluate the beneficial effects of a NO releasing cream on cutaneous leishmaniasis in an animal model. Materials and Methods: Balb/c mice were infected with leishmania major by injecting promastigotes into the base of tails of mice to induce the lesion. Then the animals were divided into 3 groups (Control, placebo and treatment). Mice were treated with the drugs one time daily. The diameter of lesions were measured on days 0, 5, 10, 15, 20, 25, and 30 after the appearance of the lesions. Data were analyzed using one-way ANOVA test and (P<0.05) considered as significant. Results: The diameter of lesions were significantly reduced in 15, 20, 25 and 30 day in NO cream treated animals compared to control and placebo groups (P<0.05). Conclusion: NO releasing compounds may be effective in the treatment of leishmaniasis.

Background: Cutaneous leishmaniasis is a common parasitic disease in Isfahan province. A common complication of cutaneous leishmaniasis is bacterial superinfection, which may intensify the disease and produce scarring. Objective: The aim of this study was to determine the bacterial species isolated from infected lesions of cutaneous leishmaniasis. Patients and Methods: Two hundred out of 874 patients with cutaneous leishmaniasis referred to Dermatology and Leishmaniasis Research Center in Amin Hospital in Isfahan during four months (September to December 1999) who had signs of bacterial superinfection were studied by taking microbial cultures from their lesions. Results: Bacterial cultures were positive in 177 cases (20.7% of all patients and 88.5% of sample patients). The isolated bacterias included S.aureus in 61.5%, S.epidermidis in 20.5%, E.coli in 3.5%, proteus vulgaris in 1.5% and Klebsiella in 1.5%. Eighty seven percent of infected patients had ulcerative nodules. Bacterial super infection was significantly more common in ulcerated lesions than non-ulcerated ones (P=0.00001).

Background: Isfahan is one of the major foci of cutaneous leishmaniasis in Iran. According to the epidemiological studies, both urban and rural forms have been reported in Isfahan. Accurate identification and characterization of Leishmania is essential for the control of the disease. Several different molecular techniques for Leishmania identification are developed including use of monoclonal antibodies. Objective: In the present study specific monoclonal antibodies against L.major (T1, T9), L.tropica (T10, T11) and L.donovani (D2) were used to identify and characterize the leishmania parasites isolated from patients with cutaneous leishmaniasis in Isfahan. Patients and Methods: Samples were obtained from borders of lesions suspicious of leishmaniasis in 298 patients, stained with Giemsa and cultured in NNN and RPMI 1640 media supplemented with 10% fetal colf serum. The promastigotes were then purified, counted and used as antigen in ELISA test. Results: Mass production of promastigotes was successful in 120 cases. L.major was identified as the causative agent of the disease in 100 cases and L.tropica in 8 patients. In 12 cases the results were inconclusive as the antigens reacted with either 2 or 3 specific monoclonal antibodies. Conclusion: L.major is the most common cause of leishmaniasis in Isfahan.
