Abstract
H uman leishmaniasis is distributed worldwide, but mainly in the tropics and subtropics, with a prevalence of 12 million cases and an approximately incidence of 0.5 million cases of VL and 1.5 million cases of cutaneous leishmaniasis (CL). Leishmania parasites are vector-born protozoan pathogens found in tropical and subtropical regions of both the old and new world. The disease in human can be divided into cutaneous, visceral, and mucosal syndromes. The aim of this study was to conduct more experiments over our previous new formulation modify leishmania major antigen that had satisfactory results, before. In this study we have made preliminarily new vaccine with the same methodology again and selected two injection doses (100 & 200 μg/0.1ml), three injection groups: Leishmania plus BCG (LB), Leishmania plus new adjuvant (Teucrium Polium)[LT], leishmania plus BCG and Teucrium Polium (LBT),and one susceptible mice(Balb/c) and measure two type cytokines: Th1(IFN-γ, IL-12) and Th2(IL-4,IL-10) and expansion of white pulp size after challenge with live leishmania. Results show that both doses over LBT group have highest IL-12, lowest IL-10 and highest increasing in spleen?s white pulp size, whether; other two groups have lower IL-12, higher IL-10 and lowest increasing in spleen?s white pulp size in susceptible mice. When all of the three groups and two genius Balb/c mice (male/female), considered, and without consideration injection dose, the largest white pulp size were seen in female Balb/c LBT group, and smallest white pulp size were seen in male Balb/c LT group). Conclusion: Our study show that in Balb/c mice, best injection group that produced highest IL-12 and lowest IL-10 and highest increasing in spleen?s white pulp size, is LBT group, which have significant differences with others. This finding show that, adjuvant BCG both Teucrium have synergic effect with together.
