Received 25 Jan Accepted 19 Aug An intense swelling of the mitochondrion with the presence of vesicles was observed in the parasites. However, the crude ethanol extract as well as the isolated compounds, ursolic acid and oleanolic acid, caused in vitro elimination of trypomastigotes at high concentrations of rarabidaea.

Antioxidant capacity of the leaf extract obtained from Arrabidaea chica cultivated in Southern Brazil. Abstract Currently available leishmaniasis treatments are limited due to severe side effects.

Despite the decrease in peptidase activity the results show that B2 was less effective against those peptidases.


Nitric oxide synthesis by Leishmania -infected macrophages treated with the B2 fraction. In a study conducted by Barbosa et al. After the parasites were washed twice in PBS they were fixed with glutaraldehyde solution 2. Taken together, the results presented herein in addition to those reported in literature concerning tissue healing effects and liver protection of A. To evaluate the inhibitory activity of B2 arrabiadea on Leishmania peptidases, parasites lysates were treated with the inhibitory and subinhibitory concentrations of the B2 fraction.

None of the extracts produced toxic effects in animals. Ultrastructure Analysis Alterations in the ultrastructure of the parasites were analyzed by transmission TEM electron microscopy.

Considering the clinical manifestations related to cutaneous and visceral leishmaniasis, such as skin lesions and hepatic damage, respectively, Arrabidaae. Preparation of extracts The leaves of A. In the present study, the reincubation of parasites treated at MIC values in fresh medium revealed that those cells were no longer able atrabidaea grow.
