Background: Bradykinin has effects on histaminic response,vessels seepage,cellular reproduction,causing fever, pain and coughs caused by ACE controllers (3,4,6). Noscapin has controlled Bradykinins contractional effects on guinea pigs trachea and rats vazodofran (5,6). noscapin stops the secondary effects of eskimi in brains edema, with antagonizing the responses caused by Bradykinin (3,4,8). Objective: considering that opium’s alkaloids act as agonist of peptide systems like ankephalins and RAS, its interesting to know the effects of this alkaloids and among them Noscapine on B3 Bradykinin receptors on smooth muscle guinea pig trachea? Method: All variables are reported as mean and standard deviation.We have used pair test and the informations were processed by Excel, Statistical analysis with ANOVA (LSD) SPSS 9. Results: we took diagrams in to consideration and indicated that the contract ional effect of Bradykinin decreased dependent on density, in presence of three different amount of noscapines concentration. In this study we could demonstrate that noscapine interact with Bradykenin as a non competitive antagonist.

Background: Treatment of leishmaniasis is a challenge due to problems such as high price and dose of the drug, drug resistance and side effects. Objective: The study aims to introduce plants compounds, which their antileishmanial effects were approved in vivo conditions. Methods: This study as a review article was performed by searching the keywords of “medicinal plants with in vivo antileishmanial effects, nanocarrier, clinical trials, and mechanism of action” in the well-known databases to 2018. In this study, 14 medicinal plant compounds with antileishmanial effects were reviewed and mechanism of action and their in vivo therapeutic effect were evaluated. Results: It was found that while some of these compounds had low antileishmanial effects, their efficacy against leishmaniasis was significantly increased through loading into nanocarriers. Conclusion: This study indicated that active component of medicinal plants especially along with nano carriers can be of interest for the treatment of Leishmania.
